# ADR-0008: Error Handling Strategy
## Status
Accepted
## Context
Go's error handling philosophy requires explicit error checking. We need a consistent approach for:
- Error creation and wrapping
- Error propagation
- Error classification (domain vs infrastructure)
- Error reporting (logging, monitoring)
- HTTP error responses
## Decision
Adopt a **wrapped error pattern** with **structured error types**:
1. **Error Wrapping**: Use `fmt.Errorf("context: %w", err)` for error wrapping
2. **Error Types**: Define custom error types for domain errors
3. **Error Classification**: Distinguish between:
- Domain errors (business logic failures)
- Infrastructure errors (external system failures)
- Validation errors (input validation failures)
4. **Error Context**: Always wrap errors with context about where they occurred
**Rationale:**
- Follows Go 1.13+ error wrapping best practices
- Enables error inspection with `errors.Is()` and `errors.As()`
- Maintains error chains for debugging
- Allows structured error handling
## Consequences
### Positive
- Full error traceability through call stack
- Can inspect and handle specific error types
- Better debugging with error context
- Aligns with Go best practices
### Negative
- Requires discipline to wrap errors consistently
- Can be verbose in some cases
### Implementation Notes
- Always wrap errors: `return nil, fmt.Errorf("failed to load config: %w", err)`
- Create error types for domain errors:
```go
type ConfigError struct {
Key string
Cause error
}
func (e *ConfigError) Error() string { ... }
func (e *ConfigError) Unwrap() error { return e.Cause }
```
- Use `errors.Is()` and `errors.As()` for error checking
- Log errors with context before returning
- Map domain errors to HTTP status codes in handlers

# ADR-0009: Context Key Types
## Status
Accepted
## Context
The platform will use `context.Context` to propagate request-scoped values such as:
- User ID (from authentication)
- Request ID (for tracing)
- Tenant ID (for multi-tenancy)
- Logger instance (with request-scoped fields)
Go best practices recommend using typed keys instead of string keys to avoid collisions.
## Decision
Use **typed context keys** for all context values:
```go
type contextKey string
const (
userIDKey contextKey = "user_id"
requestIDKey contextKey = "request_id"
tenantIDKey contextKey = "tenant_id"
loggerKey contextKey = "logger"
)
```
**Rationale:**
- Prevents key collisions between packages
- Type-safe access to context values
- Aligns with Go best practices (see `context.WithValue` documentation)
- Makes context usage explicit and discoverable
## Consequences
### Positive
- Type-safe context access
- Prevents accidental key collisions
- Clear intent in code
- Better IDE support
### Negative
- Slightly more verbose than string keys
- Requires defining keys upfront
### Implementation Notes
- Create `pkg/context/keys.go` with all context key definitions
- Provide helper functions for setting/getting values:
```go
func WithUserID(ctx context.Context, userID string) context.Context
func UserIDFromContext(ctx context.Context) (string, bool)
```
- Use in middleware and services
- Document all context keys and their usage

# ADR-0011: Code Generation Tools
## Status
Accepted
## Context
The platform will use code generation for:
- Permission constants from module manifests
- Ent ORM code generation
- Mock generation for testing
- OpenAPI client/server code (future)
We need to decide on tooling and workflow.
## Decision
Use **standard Go generation tools** with `go generate`:
1. **Ent ORM**: `entgo.io/ent/cmd/ent` for schema code generation
2. **Mocks**: `github.com/vektra/mockery/v2` or `github.com/golang/mock/mockgen`
3. **Permissions**: Custom `scripts/generate-permissions.go`
4. **OpenAPI**: `github.com/deepmap/oapi-codegen` (future)
**Workflow:**
- Use `//go:generate` directives in source files
- Run `go generate ./...` before commits
- Document in `Makefile` with `make generate` target
- CI should verify generated code is up-to-date
**Rationale:**
- Standard Go tooling, well-supported

# ADR-0012: Logger Interface Design
## Status
Accepted
## Context
We're using zap for logging, but want to abstract it behind an interface for:
- Testability (mock logger in tests)
- Flexibility (could swap implementations)
- Module compatibility (modules use interface, not concrete type)
We need to decide on the interface design.
## Decision
Create a **simple logger interface** that matches zap's API pattern but uses generic types:
```go
type Field interface {
// Field represents a key-value pair for structured logging
}
type Logger interface {
Debug(msg string, fields ...Field)
Info(msg string, fields ...Field)
Warn(msg string, fields ...Field)
Error(msg string, fields ...Field)
With(fields ...Field) Logger
}
```
**Implementation:**
- Use `zap.Field` as the Field type (no abstraction needed for now)
- Provide helper functions in `pkg/logger` for creating fields:
```go
func String(key, value string) Field
func Int(key string, value int) Field
func Error(err error) Field
```
**Rationale:**
- Simple interface that modules can depend on
- Matches zap's usage patterns
- Easy to test with mock implementations
- Allows future swap if needed (though unlikely)
## Consequences
### Positive
- Clean abstraction for modules
- Testable with mocks
- Simple API for modules to use
### Negative
- Slight indirection overhead
- Need to maintain interface compatibility
### Implementation Notes
- Define interface in `pkg/logger/logger.go`
- Implement in `internal/logger/zap_logger.go`
- Export helper functions in `pkg/logger/fields.go`
- Modules import `pkg/logger`, not `internal/logger`

- Supports PostgreSQL (primary database)
- Provides type-safe query building
- Supports code generation (reduces boilerplate)
- Handles migrations
- Supports relationships (many-to-many, etc.)
- Integrates with Ent (code generation)
Options considered:
1. **entgo.io/ent** - Code-generated, type-safe ORM
2. **gorm.io/gorm** - Feature-rich ORM with reflection
3. **sqlx** - Lightweight wrapper around database/sql
4. **Standard library database/sql** - No ORM, raw SQL
## Decision
Use **entgo.io/ent** as the primary ORM for the platform.
**Rationale:**
- Code generation provides compile-time type safety
- Excellent schema definition and migration support
- Strong relationship modeling
- Good performance (no reflection at runtime)
- Active development and good documentation
- Recommended in playbook-golang.md
- Easy to integrate with OpenTelemetry
## Consequences
### Positive
- Type-safe queries eliminate runtime errors
- Schema changes are explicit and versioned
- Code generation reduces boilerplate
- Good migration support
- Strong relationship support
### Negative
- Requires code generation step (`go generate`)
- Learning curve for developers unfamiliar with Ent
- Less flexible than raw SQL for complex queries
- Generated code must be committed or verified in CI

# ADR-0014: Health Check Implementation
## Status
Accepted
## Context
The platform needs health check endpoints for:
- Kubernetes liveness probes (`/healthz`)
- Kubernetes readiness probes (`/ready`)
- Monitoring and alerting
- Load balancer health checks
Health checks should be:
- Fast and lightweight
- Check critical dependencies (database, cache, etc.)
- Provide clear status indicators
## Decision
Implement **custom health check registry** with composable checkers:
1. **Liveness endpoint** (`/healthz`): Always returns 200 if process is running
2. **Readiness endpoint** (`/ready`): Checks all registered health checkers
3. **Health check interface**: `type HealthChecker interface { Check(ctx context.Context) error }`
4. **Registry pattern**: Modules can register additional health checkers
**Rationale:**
- Custom implementation gives full control
- Composable design allows modules to add checks
- Simple interface is easy to test
- No external dependency for basic functionality
- Can extend with Prometheus metrics later
## Consequences
### Positive
- Lightweight and fast
- Extensible by modules
- Easy to test
- Clear separation of liveness vs readiness
### Negative
- Need to implement ourselves (though simple)
- Must maintain the registry
### Implementation Notes
- Create `pkg/health/health.go` interface
- Implement `internal/health/registry.go` with checker map
- Register core checkers: database, cache (if enabled)
- Add endpoints to HTTP router

# ADR-0015: Error Bus Implementation
## Status
Accepted
## Context
The platform needs a centralized error handling mechanism for:
- Capturing panics and errors
- Logging errors consistently
- Sending errors to external services (Sentry, etc.)
- Avoiding error handling duplication
Options considered:
1. **Channel-based in-process bus** - Simple, Go-idiomatic
2. **Event bus integration** - Use existing event bus
3. **Direct logging** - No bus, direct integration
4. **External service integration** - Direct to Sentry
## Decision
Implement a **channel-based error bus** with pluggable sinks:
1. **Error bus interface**: `type ErrorPublisher interface { Publish(err error) }`
2. **Channel-based implementation**: Background goroutine consumes errors from channel
3. **Pluggable sinks**: Logger (always), Sentry (optional, Phase 6)
4. **Panic recovery middleware**: Automatically publishes panics to error bus
**Rationale:**
- Simple, idiomatic Go pattern
- Non-blocking error publishing (buffered channel)
- Decouples error capture from error handling
- Easy to add new sinks (Sentry, logging, metrics)
- Can be extended to use event bus later if needed
## Consequences
### Positive
- Centralized error handling
- Non-blocking (doesn't slow down request path)
- Easy to extend with new sinks
- Consistent error handling across the platform
### Negative
- Additional goroutine overhead (minimal)
- Must ensure error bus doesn't become bottleneck
### Implementation Notes
- Create `pkg/errorbus/errorbus.go` interface
- Implement `internal/errorbus/channel_bus.go`:
- Buffered channel (e.g., size 100)
- Background goroutine consumes errors
- Multiple sinks (logger, optional Sentry)
- Add panic recovery middleware that publishes to bus
- Register in DI container as singleton
- Monitor channel size to detect error storms

- Request tracing across services/modules
- Performance monitoring
- Debugging production issues
- Integration with observability tools (Jaeger, Grafana, etc.)
Options considered:
1. **OpenTelemetry** - Industry standard, vendor-neutral
2. **Zipkin** - Older standard, less ecosystem support
3. **Custom tracing** - Build our own
4. **No tracing** - Only logs and metrics
## Decision
Use **OpenTelemetry (OTEL)** for all observability:
1. **Tracing**: Distributed tracing with spans
2. **Metrics**: Prometheus-compatible metrics
3. **Logs**: Structured logs with trace correlation
4. **Export**: OTLP collector for production, stdout for development
**Rationale:**
- Industry standard, vendor-neutral
- Excellent Go SDK support
- Integrates with major observability tools
- Supports metrics, traces, and logs
- Recommended in playbook-golang.md
- Future-proof (not locked to specific vendor)
## Consequences
### Positive
- Vendor-neutral (can switch backends)
- Rich ecosystem and tooling
- Excellent Go SDK
- Supports all observability signals
### Negative
- Learning curve for OpenTelemetry concepts
- Slight overhead (minimal with sampling)
- Requires OTLP collector or compatible backend

# ADR-0017: JWT Token Strategy
## Status
Accepted
## Context
The platform needs authentication tokens that:
- Are stateless (no server-side session storage)
- Support role and permission claims
- Can be revoked (challenge)
- Have appropriate lifetimes
- Support multi-tenancy (tenant ID in claims)
Token strategies considered:
1. **Short-lived access tokens + long-lived refresh tokens** - Industry standard
2. **Single long-lived tokens** - Simple but insecure
3. **Short-lived tokens only** - Secure but poor UX
4. **Session-based** - Stateful, requires storage
## Decision
Use **short-lived access tokens + long-lived refresh tokens**:
1. **Access tokens**: 15 minutes lifetime, contain user ID, roles, tenant ID
2. **Refresh tokens**: 7 days lifetime, stored in database (for revocation)
3. **Token format**: JWT with claims: `sub` (user ID), `roles`, `tenant_id`, `exp`
4. **Revocation**: Refresh tokens stored in DB, can be revoked/deleted
**Rationale:**
- Industry best practice (OAuth2/OIDC pattern)
- Good balance of security and UX
- Access tokens can't be revoked (short lifetime mitigates risk)
- Refresh tokens can be revoked (stored in DB)
- Supports stateless authentication for most requests
## Consequences
### Positive

- Stateless for most requests (access tokens)
- Supports revocation (refresh tokens)
### Negative
- Requires refresh token storage (DB table)
- More complex than single token
- Need to handle token refresh flow
### Implementation Notes
- Use `github.com/golang-jwt/jwt/v5` for JWT handling
- Store refresh tokens in `refresh_tokens` table (user_id, token_hash, expires_at)
- Generate access tokens with HS256 or RS256 signing
- Include roles in token claims (not just role IDs)
- Validate token signature and expiration on each request
- Refresh endpoint validates refresh token and issues new access token

# ADR-0018: Password Hashing Algorithm
## Status
Accepted
## Context
The platform needs to securely store user passwords. Requirements:
- Resist brute-force attacks
- Resist rainbow table attacks
- Future-proof against advances in computing
- Reasonable performance (not too slow)
Options considered:
1. **bcrypt** - Battle-tested, widely used
2. **argon2id** - Modern, memory-hard, recommended by OWASP
3. **scrypt** - Memory-hard, good alternative
4. **PBKDF2** - Older standard, less secure
## Decision
Use **argon2id** for password hashing with recommended parameters:
- **Algorithm**: argon2id (variant)
- **Memory**: 64 MB (65536 KB)
- **Iterations**: 3 (time cost)
- **Parallelism**: 4 (number of threads)
- **Salt length**: 16 bytes (random, unique per password)
**Rationale:**
- Recommended by OWASP for new applications
- Memory-hard algorithm (resistant to GPU/ASIC attacks)
- Good balance of security and performance
- Future-proof design
- Standard library support in Go 1.23+
## Consequences
### Positive
- Strong security guarantees
- Memory-hard (resistant to hardware attacks)
- OWASP recommended
- Standard library support
### Negative
- Slightly slower than bcrypt (acceptable trade-off)
- Requires tuning parameters for production
### Implementation Notes
- Use `golang.org/x/crypto/argon2` package
- Store hash in format: `$argon2id$v=19$m=65536,t=3,p=4$salt$hash`
- Use `crypto/rand` for salt generation
- Verify passwords with `argon2.CompareHashAndPassword()`
- Consider increasing parameters for high-security environments

# ADR-0019: Permission DSL Format
## Status
Accepted
## Context
The platform needs a permission system that:
- Is extensible by modules
- Prevents typos and errors (compile-time safety)
- Supports hierarchical permissions
- Is easy to understand and use
Permission formats considered:
1. **String format**: `"module.resource.action"` - Simple, flexible
2. **Enum/Constants**: Type-safe but less flexible
3. **Hierarchical tree**: Complex but powerful
4. **Bitmask**: Efficient but hard to read
## Decision
Use **string-based permission format** with **code-generated constants**:
1. **Format**: `"{module}.{resource}.{action}"`
- Examples: `blog.post.create`, `user.read`, `system.health.check`
2. **Code generation**: Generate constants from `module.yaml` files
3. **Type safety**: `type Permission string` with generated constants
4. **Validation**: Compile-time constants prevent typos
**Rationale:**
- Simple and readable
- Easy to extend (modules define in manifest)
- Code generation provides compile-time safety
- Flexible (modules can define any format)
- Hierarchical structure is intuitive
- Easy to parse and match
## Consequences
### Positive
- Simple and intuitive format
- Compile-time safety via code generation
- Easy to extend by modules
- Human-readable
- Flexible for various permission models
### Negative
- String comparisons (minimal performance impact)
- Requires code generation step
- Potential for permission string conflicts (mitigated by module prefix)
### Implementation Notes
- Define `type Permission string` in `pkg/perm/perm.go`
- Create code generator: `scripts/generate-permissions.go`
- Scan `modules/*/module.yaml` for permissions
- Generate constants in `pkg/perm/generated.go`
- Use `//go:generate` directive
- Validate format: `^[a-z0-9]+(\.[a-z0-9]+)*$` (lowercase, dots)

# ADR-0020: Audit Logging Storage
## Status
Accepted
## Context
The platform needs to audit all security-relevant actions:
- User logins and authentication attempts
- Permission changes
- Data modifications
- Administrative actions
Audit logs must be:
- Immutable (append-only)
- Queryable
- Performant (don't slow down operations)
- Compliant with audit requirements
Storage options considered:
1. **PostgreSQL table** - Simple, queryable, transactional
2. **Elasticsearch** - Excellent for searching, but additional dependency
3. **File-based logs** - Simple but hard to query
4. **External audit service** - Overkill for initial version
## Decision
Store audit logs in **PostgreSQL append-only table** with JSON metadata:
1. **Table structure**: `audit_logs` with columns:
- `id`, `actor_id`, `action`, `target_id`, `metadata` (JSONB), `timestamp`
2. **Append-only**: No UPDATE or DELETE operations
3. **JSON metadata**: Flexible storage for additional context
4. **Indexing**: Index on `actor_id`, `action`, `timestamp` for queries
**Rationale:**
- Simple (no additional infrastructure)
- Queryable via SQL
- Transactional (consistent with other data)
- JSONB provides flexibility for metadata
- Can migrate to Elasticsearch later if needed
- Good performance for typical audit volumes
## Consequences
### Positive
- Simple implementation
- Queryable via SQL
- No additional infrastructure
- Transactional consistency
- Can archive old logs if needed
### Negative
- Adds load to primary database
- May need archiving strategy for large volumes
- Less powerful search than Elasticsearch
### Implementation Notes
- Create `audit_logs` table via Ent schema
- Use JSONB for metadata column (PostgreSQL-specific)
- Add indexes: `(actor_id, timestamp)`, `(action, timestamp)`
- Implement async logging (optional, via channel) for high throughput
- Consider partitioning by date for large volumes
- Add retention policy (e.g., archive after 1 year)

# ADR-0021: Module Loading Strategy
## Status
Accepted
## Context
The platform needs to support pluggable modules. Two approaches:
1. **Static registration** - Modules compiled into binary
2. **Dynamic plugin loading** - Load `.so` files at runtime
Each has trade-offs for development, CI, and production.
## Decision
Support **both approaches** with **static registration as primary**:
1. **Static registration (primary)**:
- Modules register via `init()` function
- Imported via `import _ "module/pkg"` in main
- Works everywhere (Windows, Linux, macOS)
- Compile-time type safety
2. **Dynamic plugin loading (optional)**:
- Support via Go `plugin` package
- Load `.so` files from `./plugins/` directory
- Only for production scenarios requiring hot-swap
- Linux/macOS only (Go plugin limitation)
**Rationale:**
- Static registration is simpler and more reliable
- Works in CI/CD (no plugin compilation needed)
- Compile-time safety catches errors early
- Dynamic loading provides flexibility for specific use cases
- Modules can choose their approach
## Consequences
### Positive
- Flexible: static for most cases, dynamic when needed
- Static registration works everywhere
- Compile-time safety with static
- Hot-swap capability with dynamic (Linux/macOS)
### Negative
- Two code paths to maintain
- Dynamic plugins have version compatibility constraints
- Plugin debugging is harder
### Implementation Notes
- Implement static registry in `internal/registry/registry.go`
- Modules register via: `registry.Register(Module)` in `init()`
- Implement plugin loader in `internal/pluginloader/plugin_loader.go` (optional)
- Document when to use each approach
- Validate plugin version compatibility if using dynamic loading

# ADR-0022: Cache Implementation
## Status
Accepted
## Context
The platform needs caching for:
- Performance optimization (reduce database load)
- Frequently accessed data (user permissions, roles)
- Session data (optional)
- Query results
Options considered:
1. **Redis** - Industry standard, feature-rich
2. **In-memory cache** - Simple, no external dependency
3. **Memcached** - Simple, but less features than Redis
4. **No cache** - Simplest, but poor performance at scale
## Decision
Use **Redis** as the primary cache with **in-memory fallback**:
1. **Primary**: Redis for production
2. **Fallback**: In-memory cache for development/testing
3. **Interface abstraction**: `Cache` interface allows swapping implementations
4. **Use cases**: Permission lookups, role assignments, query caching
**Rationale:**
- Industry standard, widely supported
- Rich feature set (TTL, pub/sub, etc.)
- Can be shared across instances (multi-instance deployments)
- Good performance
- Easy to abstract behind interface
## Consequences
### Positive
- High performance
- Shared across instances
- Rich feature set
- Easy to scale horizontally
- Abstraction allows swapping implementations
### Negative
- Additional infrastructure dependency
- Network latency (minimal with proper setup)
- Need to handle Redis failures gracefully
### Implementation Notes
- Install: `github.com/redis/go-redis/v9`
- Create `pkg/infra/cache/cache.go` interface
- Implement `internal/infra/cache/redis_cache.go`
- Implement `internal/infra/cache/memory_cache.go` for fallback
- Use connection pooling
- Handle Redis failures gracefully (fallback or error)
- Configure TTLs appropriately (e.g., 5 minutes for permissions)

# ADR-0023: Event Bus Implementation
## Status
Accepted
## Context
The platform needs an event bus for:
- Module-to-module communication
- Decoupled event publishing
- Event sourcing (optional, future)
- Integration with external systems
Options considered:
1. **In-process channel-based bus** - Simple, for development/testing
2. **Kafka** - Production-grade, scalable
3. **RabbitMQ** - Alternative message broker
4. **Redis pub/sub** - Simple but less reliable
## Decision
Support **dual implementation** with **in-process primary, Kafka for production**:
1. **In-process bus (default)**:
- Channel-based implementation
- Used for development, testing, small deployments
- Simple, no external dependencies
2. **Kafka bus (production)**:
- Full Kafka integration via `segmentio/kafka-go`
- Producer/consumer groups
- Configurable via environment (switch implementation)
**Rationale:**
- In-process bus is simple for development
- Kafka provides production-grade reliability and scalability
- Interface abstraction allows swapping
- Modules don't need to know which implementation
- Can start simple and scale up
## Consequences
### Positive
- Simple for development (no Kafka needed)
- Scalable for production (Kafka)
- Flexible (can choose implementation)
- Modules are decoupled from implementation
### Negative
- Two implementations to maintain
- Need to ensure interface covers both use cases

# ADR-0025: Multi-tenancy Model
## Status
Accepted
## Context
The platform may need multi-tenancy support for SaaS deployments. Options:
1. **Shared database with tenant_id column** - Single DB, row-level isolation
2. **Schema-per-tenant** - Single DB, separate schemas
3. **Database-per-tenant** - Separate databases
Each has trade-offs for isolation, performance, and operational complexity.
## Decision
Use **shared database with tenant_id column** (optional feature):
1. **Model**: Single PostgreSQL database with `tenant_id` column on tenant-scoped tables
2. **Isolation**: Row-level via Ent interceptors (automatic filtering)
3. **Tenant resolution**: From header (`X-Tenant-ID`), subdomain, or JWT claim
4. **Optional**: Can be disabled for single-tenant deployments
**Rationale:**
- Simplest operational model (single database)
- Good performance (can index tenant_id)
- Easy to implement (Ent interceptors)
- Can migrate to schema-per-tenant later if needed
- Flexible (can support both single and multi-tenant)
## Consequences
### Positive
- Simple operations (single database)
- Good performance with proper indexing
- Easy to implement
- Flexible (optional feature)
### Negative

## Status
Accepted
## Context
The platform needs rate limiting to:
- Prevent abuse and DoS attacks
- Protect against brute-force attacks
- Ensure fair resource usage
- Comply with API usage policies
Rate limiting strategies:
1. **Per-user rate limiting** - Based on authenticated user
2. **Per-IP rate limiting** - Based on client IP

# Go‑Platform Boilerplate Play‑book
**“Plug‑in‑friendly SaaS/Enterprise Platform – Go Edition”**
## 1️⃣ ARCHITECTURAL IMPERATIVES (Go‑flavoured)
| Principle | Go‑specific rationale | Enforcement Technique |
|-----------|-----------------------|------------------------|
| **Clean / Hexagonal Architecture** | Go’s package‑level visibility (`internal/`) naturally creates a *boundary* between core and plug‑ins. | Keep all **domain** code in `internal/domain`, expose only **interfaces** in `pkg/`. |
| **Dependency Injection (DI) via Constructors** | Go avoids reflection‑heavy containers; compile‑time wiring is preferred. | Use **uber‑go/fx** (runtime graph) *or* **uber‑go/dig** for optional runtime DI. For a lighter weight solution, use plain **constructor injection** with a small **registry**. |
| **Modular Monolith → Micro‑service‑ready** | A single binary is cheap in Go; later you can extract modules into separate services without breaking APIs. | Each module lives in its own Go **module** (`go.mod`) under `./modules/*`. The core loads them via the **Go plugin** system *or* static registration (preferred for CI stability). |
| **Plugin‑first design** | Go’s `plugin` package allows runtime loading of compiled `.so` files (Linux/macOS). | Provide an **IModule** interface and a **loader** that discovers `*.so` files (or compiled‑in modules for CI). |
| **API‑First (OpenAPI + gin/gorilla)** | Guarantees language‑agnostic contracts. | Generate server stubs from an `openapi.yaml` stored in `api/`. |
| **Security‑by‑Design** | Go’s static typing makes it easy to keep auth data out of the request flow. | Central middleware for JWT verification + context‑based user propagation. |
| **Observability (OpenTelemetry)** | The Go ecosystem ships first‑class OTEL SDK. | Instrument HTTP, DB, queues, and custom events automatically. |
| **Configuration‑as‑Code** | Viper + Cobra give hierarchical config and flag parsing. | Load defaults → file → env → secret manager (AWS Secrets Manager / Vault). |
| **Testing & CI** | `go test` is fast; Testcontainers via **testcontainers-go** can spin up DB, Redis, Kafka. | CI pipeline runs unit, integration, and contract tests on each PR. |
| **Semantic Versioning & Compatibility** | Go modules already enforce version constraints. | Core declares **minimal required versions** in `go.mod` and uses `replace` for local dev. |
---
## 2️⃣ CORE KERNEL (What every Go‑platform must ship)
| Module | Public Interfaces (exported from `pkg/`) | Recommended Packages | Brief Implementation Sketch |
|--------|-------------------------------------------|----------------------|------------------------------|
| **Config** | `type ConfigProvider interface { Get(key string) any; Unmarshal(v any) error }` | `github.com/spf13/viper` | Load defaults (`config/default.yaml`), then env overrides, then optional secret‑store. |
| **Logger** | `type Logger interface { Debug(msg string, fields ...Field); Info(...); Error(...); With(fields ...Field) Logger }` | `go.uber.org/zap` (or `zerolog`) | Global logger is created in `cmd/main.go`; exported via `pkg/logger`. |
| **DI / Service Registry** | `type Container interface { Provide(constructor any) error; Invoke(fn any) error }` | `go.uber.org/dig` (or `fx` for lifecycle) | Core creates a `dig.New()` container, registers core services, then calls `container.Invoke(app.Start)`. |
| **Health & Metrics** | `type HealthChecker interface { Check(ctx context.Context) error }` | `github.com/prometheus/client_golang/prometheus`, `github.com/heptiolabs/healthcheck` | Expose `/healthz`, `/ready`, `/metrics`. |
| **Error Bus** | `type ErrorPublisher interface { Publish(err error) }` | Simple channel‐based implementation + optional Sentry (`github.com/getsentry/sentry-go`) | Core registers a singleton `ErrorBus`. |
| **Auth (JWT + OIDC)** | `type Authenticator interface { GenerateToken(userID string, roles []string) (string, error); VerifyToken(token string) (*TokenClaims, error) }` | `github.com/golang-jwt/jwt/v5`, `github.com/coreos/go-oidc` | Token claims embed `sub`, `roles`, `tenant_id`. Middleware adds `User` to `context.Context`. |
| **Authorization (RBAC/ABAC)** | `type Authorizer interface { Authorize(ctx context.Context, perm Permission) error }` | Custom DSL, `github.com/casbin/casbin/v2` (optional) | Permission format: `"module.resource.action"`; core ships a simple in‑memory resolver and a `casbin` adapter. |
| **Audit** | `type Auditor interface { Record(ctx context.Context, act AuditAction) error }` | Write to append‑only table (Postgres) or Elastic via `olivere/elastic` | Audits include `actorID`, `action`, `targetID`, `metadata`. |
| **Event Bus** | `type EventBus interface { Publish(ctx context.Context, ev Event) error; Subscribe(topic string, handler EventHandler) }` | `github.com/segmentio/kafka-go` (for production) + in‑process fallback | Core ships an **in‑process bus** used by tests and a **Kafka bus** for real deployments. |
| **Persistence (Repository)** | `type UserRepo interface { FindByID(id string) (*User, error); Create(u *User) error; … }` | `entgo.io/ent` (code‑gen ORM) **or** `gorm.io/gorm` | Core provides an `EntClient` wrapper that implements all core repos. |
| **Scheduler / Background Jobs** | `type Scheduler interface { Cron(spec string, job JobFunc) error; Enqueue(q string, payload any) error }` | `github.com/robfig/cron/v3`, `github.com/hibiken/asynq` (Redis‑backed) | Expose a `JobRegistry` where modules can register periodic jobs. |
| **Notification** | `type Notifier interface { Send(ctx context.Context, n Notification) error }` | `github.com/go-mail/mail` (SMTP), `github.com/aws/aws-sdk-go-v2/service/ses`, `github.com/IBM/sarama` (for push) | Core supplies an `EmailNotifier` and a `WebhookNotifier`. |
| **Multitenancy (optional)** | `type TenantResolver interface { Resolve(ctx context.Context) (tenantID string, err error) }` | Header/ sub‑domain parser + JWT claim scanner | Tenant ID is stored in request context and automatically added to SQL queries via Ent’s `Client` interceptor. |
All *public* interfaces live under `pkg/` so that plug‑ins can import them without pulling in implementation details. The concrete implementations stay in `internal/` (or separate go.mod modules) and are **registered with the container** during bootstrap.
---
## 3️⃣ MODULE (PLUGIN) FRAMEWORK
### 3.1 Interface that every module must implement
```go
// pkg/module/module.go
package module
import (
"context"
"go.uber.org/fx"
)
// IModule is the contract a feature plug‑in must fulfil.
type IModule interface {
// Name returns a unique, human‑readable identifier.
Name() string
// Init registers the module's services, routes, jobs, and permissions.
// The fx.Options returned are merged into the app's lifecycle.
Init() fx.Option
// Migrations returns a slice of Ent migration functions (or raw SQL) that
// the core will run when the platform starts.
Migrations() []func(*ent.Client) error
}
```
### 3.2 Registration Mechanics
Two ways to get a module into the platform:
| Approach | When to use | Pros | Cons |
|----------|-------------|------|------|
| **Static registration** – each module imports `core` and calls `module.Register(MyBlogModule{})` in its own `init()` | Development, CI (no `.so` needed) | Simpler, works on Windows; compile‑time type safety | Requires recompiling the binary for new modules |
| **Runtime `plugin` loading** – compile each module as a `go build -buildmode=plugin -o blog.so ./modules/blog` | Production SaaS where clients drop new modules, or separate micro‑service extraction | Hot‑swap without rebuild | Only works on Linux/macOS; plugins must be compiled with same Go version & same `go.mod` replace graph; debugging harder |
**Static registration example**
```go
// internal/registry/registry.go
package registry
import (
"sync"
"github.com/yourorg/platform/pkg/module"
)
var (
mu sync.Mutex
modules = make(map[string]module.IModule)
)
func Register(m module.IModule) {
mu.Lock()
defer mu.Unlock()
if _, ok := modules[m.Name()]; ok {
panic("module already registered: " + m.Name())
}
modules[m.Name()] = m
}
func All() []module.IModule {
mu.Lock()
defer mu.Unlock()
out := make([]module.IModule, 0, len(modules))
for _, m := range modules {
out = append(out, m)
}
return out
}
```
**Plugin loader skeleton**
```go
// internal/pluginloader/loader.go
package pluginloader
import (
"plugin"
"github.com/yourorg/platform/pkg/module"
)
func Load(path string) (module.IModule, error) {
p, err := plugin.Open(path)
if err != nil {
return nil, err
}
sym, err := p.Lookup("Module")
if err != nil {
return nil, err
}
mod, ok := sym.(module.IModule)
if !ok {
return nil, fmt.Errorf("invalid module type")
}
return mod, nil
}
```
> **Tip:** Ship a tiny CLI (`platformctl modules list`) that scans `./plugins/*.so`, loads each via `Load`, and prints `Name()`. This is a great sanity check for ops.
### 3.3 Permissions DSL (compile‑time safety)
```go
// pkg/perm/perm.go
package perm
type Permission string
func (p Permission) String() string { return string(p) }
var (
// Core permissions
SystemHealthCheck Permission = "system.health.check"
// Blog module – generated by a small go:generate script
BlogPostCreate Permission = "blog.post.create"
BlogPostRead Permission = "blog.post.read"
BlogPostUpdate Permission = "blog.post.update"
BlogPostDelete Permission = "blog.post.delete"
)
```
A **code‑gen** tool (`go generate ./...`) can scan each module’s `module.yaml` for declared actions and emit a single `perm.go` file, guaranteeing no duplicate strings.
---
## 4️⃣ SAMPLE FEATURE MODULE – **Blog**
```
modules/
└─ blog/
├─ go.mod # (module github.com/yourorg/blog)
├─ module.yaml
├─ internal/
│ ├─ api/
│ │ └─ handler.go
│ ├─ domain/
│ │ ├─ post.go
│ │ └─ post_repo.go
│ └─ service/
│ └─ post_service.go
└─ pkg/
└─ module.go
```
### 4.1 `module.yaml`
```yaml
name: blog
version: 0.1.0
dependencies:
- core >= 1.3.0
permissions:
- blog.post.create
- blog.post.read
- blog.post.update
- blog.post.delete
routes:
- method: POST
path: /api/v1/blog/posts
permission: blog.post.create
- method: GET
path: /api/v1/blog/posts/:id
permission: blog.post.read
```
### 4.2 Go implementation
```go
// pkg/module.go
package blog
import (
"github.com/yourorg/platform/pkg/module"
"go.uber.org/fx"
)
type BlogModule struct{}
func (b BlogModule) Name() string { return "blog" }
func (b BlogModule) Init() fx.Option {
return fx.Options(
// Register repository implementation
fx.Provide(NewPostRepo),
// Register service layer
fx.Provide(NewPostService),
// Register HTTP handlers (using Gin)
fx.Invoke(RegisterHandlers),
// Register permissions (optional – just for documentation)
fx.Invoke(RegisterPermissions),
)
}
func (b BlogModule) Migrations() []func(*ent.Client) error {
// Ent migration generated in internal/ent/migrate
return []func(*ent.Client) error{
func(c *ent.Client) error { return c.Schema.Create(context.Background()) },
}
}
// Export a variable for the plugin loader
var Module BlogModule
```
**Handler registration (Gin example)**
```go
// internal/api/handler.go
package api
import (
"github.com/gin-gonic/gin"
"github.com/yourorg/blog/internal/service"
"github.com/yourorg/platform/pkg/perm"
"github.com/yourorg/platform/pkg/auth"
)
func RegisterHandlers(r *gin.Engine, svc *service.PostService, authz auth.Authorizer) {
grp := r.Group("/api/v1/blog")
grp.Use(auth.AuthMiddleware()) // verifies JWT, injects user in context
// POST /posts
grp.POST("/posts", func(c *gin.Context) {
if err := authz.Authorize(c.Request.Context(), perm.BlogPostCreate); err != nil {
c.JSON(403, gin.H{"error": "forbidden"})
return
}
// decode request, call svc.Create, return 201…
})
// GET /posts/:id (similar)
}
```
**Repository using Ent**
```go
// internal/domain/post_repo.go
package domain
import (
"context"
"github.com/yourorg/platform/internal/ent"
"github.com/yourorg/platform/internal/ent/post"
)
type PostRepo struct{ client *ent.Client }
func NewPostRepo(client *ent.Client) *PostRepo { return &PostRepo{client} }
func (r *PostRepo) Create(ctx context.Context, p *Post) (*Post, error) {
entPost, err := r.client.Post.
Create().
SetTitle(p.Title).
SetContent(p.Content).
SetAuthorID(p.AuthorID).
Save(ctx)
if err != nil {
return nil, err
}
return fromEnt(entPost), nil
}
```
> **Result:** Adding a new feature is just a matter of creating a new folder under `modules/`, implementing `module.IModule`, registering routes, permissions and migrations. The core automatically wires everything together.

## 5️⃣ INFRASTRUCTURE ADAPTERS (swap‑able, per‑environment)
| Concern | Implementation (Go) | Where it lives |
|---------|---------------------|----------------|
| **Database** | `entgo.io/ent` (code‑gen) | `internal/infra/ent/` |
| **Cache** | `github.com/go-redis/redis/v9` | `internal/infra/cache/` |
| **Message Queue** | `github.com/segmentio/kafka-go` (Kafka) **or** `github.com/hibiken/asynq` (Redis) | `internal/infra/bus/` |
| **Blob Storage** | `github.com/aws/aws-sdk-go-v2/service/s3` (or GCS) | `internal/infra/blob/` |
| **Email** | `github.com/go-mail/mail` (SMTP) | `internal/infra/email/` |
| **SMS / Push** | Twilio SDK, Firebase Cloud Messaging | `internal/infra/notify/` |
| **Secret Store** | AWS Secrets Manager (`aws-sdk-go-v2`) or HashiCorp Vault (`github.com/hashicorp/vault/api`) | `internal/infra/secret/` |
All adapters expose an **interface** in `pkg/infra/…` and are registered in the DI container as **singletons**.
---
## 6️⃣ OBSERVABILITY STACK
| Layer | Library | What it does |
|-------|---------|--------------|
| **Tracing** | `go.opentelemetry.io/otel`, `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` | Auto‑instrument HTTP, DB (Ent plugin), Kafka, Redis |
| **Metrics** | `github.com/prometheus/client_golang/prometheus` | Counter/Histogram per request, DB latency, job execution |
| **Logging** | `go.uber.org/zap` (structured JSON) | Global logger, request‑scoped fields (`request_id`, `user_id`, `tenant_id`) |
| **Error Reporting** | `github.com/getsentry/sentry-go` (optional) | Capture panics & errors, link to trace ID |
| **Dashboard** | Grafana + Prometheus + Loki (logs) | Provide ready‑made dashboards in `ops/` folder |
**Instrumentation example (HTTP)**
```go
import (
"net/http"
"go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp"
)
func main() {
r := gin.New()
// Wrap the entire router with OTEL middleware
wrapped := otelhttp.NewHandler(r, "http-server")
http.ListenAndServe(":8080", wrapped)
}
```
**Metrics middleware**
```go
func PromMetrics() gin.HandlerFunc {
return func(c *gin.Context) {
start := time.Now()
c.Next()
duration := time.Since(start).Seconds()
method := c.Request.Method
path := c.FullPath()
status := fmt.Sprintf("%d", c.Writer.Status())
requestDuration.WithLabelValues(method, path, status).Observe(duration)
}
}
```
---
## 7️⃣ CONFIGURATION & ENVIRONMENT
```
config/
├─ default.yaml # baseline values
├─ development.yaml
├─ production.yaml
└─ secrets/ # git‑ignored, loaded via secret manager
```
**Bootstrap**
```go
func LoadConfig() (*Config, error) {
v := viper.New()
v.SetConfigName("default")
v.AddConfigPath("./config")
if err := v.ReadInConfig(); err != nil { return nil, err }
env := v.GetString("environment") // dev / prod / test
v.SetConfigName(env)
v.MergeInConfig() // overrides defaults
v.AutomaticEnv() // env vars win
// optional: secret manager overlay
return &Config{v}, nil
}
```
All services receive a `*Config` via DI.
---
## 8️⃣ CI / CD PIPELINE (GitHub Actions)
```yaml
name: CI
on:
push:
branches: [main]
pull_request:
jobs:
build:
runs-on: ubuntu-latest
env:
GO111MODULE: on
steps:
- uses: actions/checkout@v4
- name: Set up Go
uses: actions/setup-go@v5
with:
go-version: '1.22'
- name: Cache Go modules
uses: actions/cache@v4
with:
path: |
~/.cache/go-build
~/go/pkg/mod
key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }}
- name: Install Tools
run: |
go install github.com/vektra/mockery/v2@latest
go install github.com/golang/mock/mockgen@latest
- name: Lint
run: |
go install golang.org/x/lint/golint@latest
golint ./...
- name: Unit Tests
run: |
go test ./... -cover -race -short
- name: Integration Tests (Docker Compose)
run: |
docker compose -f ./docker-compose.test.yml up -d
go test ./... -tags=integration -count=1
docker compose -f ./docker-compose.test.yml down
- name: Build Binaries
run: |
go build -ldflags="-X main.version=${{ github.sha }}" -o bin/platform ./cmd/platform

uses: docker/build-push-action@v5
with:
context: .
push: ${{ github.ref == 'refs/heads/main' }}
tags: ghcr.io/yourorg/platform:${{ github.sha }}
```
**Key points**
* `go test ./... -tags=integration` runs tests that spin up Postgres, Redis, Kafka via **Testcontainers** (`github.com/testcontainers/testcontainers-go`).
* Linting via `golint` or `staticcheck`.
* Docker image built from the compiled binary (multi‑stage: `golang:1.22-alpine` → `scratch` or `distroless`).
* Semantic‑release can be added on top (`semantic-release` action) to tag releases automatically.
---
## 9️⃣ TESTING STRATEGY
| Test type | Tools | Typical coverage |
|-----------|-------|------------------|
| **Unit** | `testing`, `github.com/stretchr/testify`, `github.com/golang/mock` | Individual services, repositories (use in‑memory DB or mocks). |
| **Integration** | `testcontainers-go` for Postgres, Redis, Kafka; real Ent client | End‑to‑end request → DB → event bus flow. |
| **Contract** | `pact-go` or **OpenAPI** validator middleware (`github.com/getkin/kin-openapi`) | Guarantees that modules do not break the published API. |
| **Load / Stress** | `k6` or `vegeta` scripts in `perf/` | Verify that auth middleware adds < 2 ms latency per request. |
| **Security** | `gosec`, `zap` for secret detection, OWASP ZAP for API scan | Detect hard‑coded secrets, SQL injection risk. |
**Example integration test skeleton**
```go
func TestCreatePost_Integration(t *testing.T) {
ctx := context.Background()
// Spin up a PostgreSQL container
pg, err := testcontainers.GenericContainer(ctx, testcontainers.GenericContainerRequest{
ContainerRequest: testcontainers.ContainerRequest{
Image: "postgres:15-alpine",
Env: map[string]string{"POSTGRES_PASSWORD": "secret", "POSTGRES_DB": "test"},
ExposedPorts: []string{"5432/tcp"},
WaitingFor: wait.ForListeningPort("5432/tcp"),
},
Started: true,
})
require.NoError(t, err)
defer pg.Terminate(ctx)
// Build DSN from container host/port
host, _ := pg.Endpoint(ctx)
dsn := fmt.Sprintf("postgres://postgres:secret@%s/test?sslmode=disable", host)
// Initialize Ent client against that DSN
client, err := ent.Open("postgres", dsn)
require.NoError(t, err)
defer client.Close()
// Run schema migration
err = client.Schema.Create(ctx)
require.NoError(t, err)
// Build the whole app using fx, injecting the test client
app := fx.New(
core.ProvideAll(),
fx.Provide(func() *ent.Client { return client }),
blog.Module.Init(),
// ...
)
// Start the app, issue a HTTP POST request through httptest.Server,
// assert 201 and DB row existence.
}
```
---
## 10️⃣ COMMON PITFALLS & SOLUTIONS (Go‑centric)
| Pitfall | Symptom | Remedy |
|---------|----------|--------|
| **Circular imports** (core ↔ module) | `import cycle not allowed` build error | Keep **interfaces only** in `pkg/`. Core implements, modules depend on the interface only. |
| **Too‑big binary** (all modules compiled in) | Long build times, memory pressure on CI | Use **Go plugins** for truly optional modules; keep core binary minimal. |
| **Version mismatch with plugins** | Panic: `plugin was built with a different version of package X` | Enforce a **single `replace` directive** for core in each module’s `go.mod` (e.g., `replace github.com/yourorg/platform => ../../platform`). |
| **Context leakage** (request data not passed) | Logs missing `user_id`, permission checks use zero‑value user | Always store user/tenant info in `context.Context` via middleware; provide helper `auth.FromContext(ctx)`. |
| **Ent migrations out‑of‑sync** | Startup fails with “column does not exist” | Run `go generate ./...` (ent codegen) and `ent/migrate` automatically at boot **after all module migrations are collected**. |
| **Hard‑coded permission strings** | Typos go unnoticed → 403 bugs | Use the **generated `perm` package** (see §4.1) and reference constants everywhere. |
| **Blocking I/O in request path** | 500 ms latency spikes | Off‑load long‑running work to **asynq jobs** or **Kafka consumers**; keep request handlers thin. |
| **Over‑exposed HTTP handlers** | Missing auth middleware → open endpoint | Wrap the router with a **global security middleware** that checks a whitelist and enforces `Authorizer` for everything else. |
| **Memory leaks with goroutine workers** | Leak after many module reloads | Use **fx.Lifecycle** to start/stop background workers; always cancel contexts on `Stop`. |
| **Testing with real DB slows CI** | Pipeline > 10 min | Use **testcontainers** in parallel jobs, cache Docker images, or use in‑memory SQLite for unit tests and only run DB‑heavy tests in a dedicated job. |
---
## 11️⃣ QUICK‑START STEPS (What to code first)
1. **Bootstrap repo**
```bash
mkdir platform && cd platform
go mod init github.com/yourorg/platform
mkdir cmd internal pkg config modules
touch cmd/main.go
```
2. **Create core container** (`internal/di/container.go`) using `dig`. Register Config, Logger, DB, EventBus, Authenticator, Authorizer.
3. **Add Auth middleware** (`pkg/auth/middleware.go`) that extracts JWT, validates claims, injects `User` into context.
4. **Implement Permission DSL** (`pkg/perm/perm.go`) and a **simple in‑memory resolver** (`pkg/perm/resolver.go`).
5. **Write `module` interface** (`pkg/module/module.go`) and a **static registry** (`internal/registry/registry.go`).
6. **Add first plug‑in** – copy the **Blog** module skeleton from §4.
`cd modules/blog && go mod init github.com/yourorg/blog && go run ../..` (build & test).
7. **Wire everything in `cmd/main.go`** using `fx.New(...)`:
```go
app := fx.New(
core.Module, // registers core services
fx.Invoke(registry.RegisterAllModules), // loads static modules
fx.Invoke(func(lc fx.Lifecycle, r *gin.Engine) {
lc.Append(fx.Hook{
OnStart: func(context.Context) error {
go r.Run(":8080")
return nil
},
OnStop: func(ctx context.Context) error { return nil },
})
}),
)
app.Run()
```
8. **Run integration test** (`go test ./... -tags=integration`) to sanity‑check DB + routes.
9. **Add CI workflow** (copy the `.github/workflows/ci.yml` from §8) and push.
10. **Publish first Docker image** (`docker build -t ghcr.io/yourorg/platform:dev .`).
After step 10 you have a **complete, production‑grade scaffolding** that:
* authenticates users via JWT (with optional OIDC),
* authorizes actions through a compile‑time‑checked permission DSL,
* logs/metrics/traces out of the box,
* lets any team drop a new `*.so` or static module under `modules/` to add resources,
* ships with a working CI pipeline and a ready‑to‑run Docker image.

## 12️⃣ REFERENCE IMPLEMENTATION (public)
If you prefer to start from a **real open‑source baseline**, check out the following community projects that already adopt most of the ideas above:
| Repo | Highlights |
|------|------------|
| `github.com/go‑microservices/clean‑arch` | Clean‑architecture skeleton, fx DI, Ent ORM, JWT auth |
| `github.com/ory/hydra` | Full OIDC provider (good for auth reference) |
| `github.com/segmentio/kafka-go` examples | Event‑bus integration |
| `github.com/ThreeDotsLabs/watermill` | Pub/sub abstraction usable as bus wrapper |
| `github.com/hibiken/asynq` | Background job framework (Redis based) |
Fork one, strip the business logic, and rename the packages to match *your* `github.com/yourorg/platform` namespace.

# Requirements
## 1️⃣ HIGH‑LEVEL ARCHITECTURAL PRINCIPLES
| Principle | Why it matters for a modular platform | How to enforce it |
|-----------|----------------------------------------|-------------------|
| **Separation of Concerns (SoC)** | Keeps core services (auth, audit, config) independent from business modules. | Use **layered** or **hexagonal/clean‑architecture** boundaries. |
| **Domain‑Driven Design (DDD) Bounded Contexts** | Allows each module to own its own model & rules while sharing a common identity kernel. | Define a **Core Context** (Identity, Security, Infrastructure) and **Feature Contexts** (Billing, CMS, Chat, …). |
| **Modular Monolith → Micro‑service‑ready** | Start simple (single process) but keep each module in its own package so you can later split to services if needed. | Package each module as an **independent library** with its own **DI container‑module** and **routing**. |
| **Plug‑in / Extension‑point model** | Enables customers or internal teams to drop new features without touching core code. | Export **well‑defined interfaces** (e.g., `IUserProvider`, `IPermissionResolver`, `IModuleInitializer`). |
| **API‑First** | Guarantees that any UI (web, mobile, CLI) can be built on top of the same contract. | Publish **OpenAPI/GraphQL schema** as part of the build artefact. |
| **Security‑by‑Design** | The platform will hold user credentials, roles and possibly PII. | Centralize **authentication**, **authorization**, **audit**, **rate‑limiting**, **CORS**, **CSP**, **secure defaults**. |
| **Observability** | You need to know when a plug‑in crashes or misbehaves. | Provide **structured logging**, **metrics**, **tracing**, **health‑checks**, **central error bus**. |
| **CI/CD‑Ready Boilerplate** | Keeps the framework maintainable and encourages best‑practice adoption. | Include **GitHub Actions / GitLab CI** pipelines that run lint, unit, integration, contract tests, and a publish step. |
| **Configuration‑as‑Code** | Each module may need its own settings but you want a single source of truth. | Use a **hierarchical config system** (environment > file > secret store). |
| **Multitenancy (optional)** | If you plan SaaS, the core must be ready to isolate data per tenant. | Provide **tenant‑aware repository abstractions** and **tenant‑scoped middlewares**. |
| **Versioning & Compatibility** | Modules evolve; the core should never break existing plug‑ins. | Adopt **semantic versioning** + **backwards‑compatibility shim layer** (e.g., deprecation warnings). |
---
## 2️⃣ LAYERED / HEXAGONAL BLUEPRINT
```
+---------------------------------------------------+
| Presentation |
| (REST/GraphQL/ gRPC Controllers, UI SDKs, CLI) |
+-------------------+-------------------------------+
| Application Services (Use‑cases) |
| - orchestrate core & feature modules |
| - enforce policies (RBAC, rate‑limit) |
+-------------------+-------------------------------+
| Domain (Business Logic) |
| - Core Entities (User, Role, Permission) |
| - Domain Services (PasswordPolicy, TokenMgr) |
+-------------------+-------------------------------+
| Infrastructure / Adapters |
| - Persistence (ORM/NoSQL Repositories) |
| - External services (Email, SMS, OIDC) |
| - Event bus (Kafka/Rabbit, In‑process) |
| - File storage, Cache, Search |
+---------------------------------------------------+
| Platform Core (Kernel) |
| - DI container, Module loader, Config manager |
| - Cross‑cutting concerns (Logging, Metrics) |
| - Security subsystem (AuthN/AuthZ, Token Issuer)|
+---------------------------------------------------+
```
*All layers talk to each other **through interfaces** defined in the Core kernel. Feature modules implement those interfaces and register themselves at startup.*
---
## 3️⃣ REQUIRED BASE MODULES (THE “CORE KERNEL”)
| Module | Core responsibilities | Public API / Extension points |
|--------|-----------------------|--------------------------------|
| **Identity‑Management** | - User CRUD (local + federation) <br>- Password hashing, reset flow <br>- Email/Phone verification | `IUserRepository`, `IUserService`, `IExternalIdpProvider` |
| **Roles & Permissions** | - Role hierarchy (role → permission set) <br>- Permission definitions (string, enum, policy) <br>- Dynamic permission evaluation (ABAC) | `IPermissionResolver`, `IRoleService` |
| **Authentication** | - JWT / OAuth2 Access & Refresh tokens <br>- OpenID Connect Provider (optional) <br>- Session Management (stateless + optional stateful) | `IAuthService`, `ITokenProvider` |
| **Authorization Middleware** | - Enforce RBAC/ABAC on each request <br>- Policy DSL (e.g., `hasPermission('project.read') && resource.ownerId == user.id`) | `IAuthorizationHandler` |
| **Audit & Activity Log** | - Immutable log of security‑relevant actions <br>- Correlation IDs, actor, target, timestamp | `IAuditSink`, `IAuditService` |
| **Configuration** | - Hierarchical sources (env, files, secret manager) <br>- Validation schema (JSON‑Schema / Yup / JSR‑380) | `IConfigProvider` |
| **Health & Metrics** | - `/healthz`, `/ready`, `/metrics` endpoints <br>- Export to Prometheus, Grafana, CloudWatch | `IHealthCheck`, `IMetricsRegistry` |
| **Error Handling** | - Centralized error objects, stack trace masking <br>- Automatic mapping to HTTP status <br>- Exception‑to‑event publishing | `IErrorMapper`, `IErrorBus` |
| **Logging** | - Structured JSON logs (level, requestId, userId) <br>- pluggable sinks (stdout, file, ELK, Cloud Logging) | `ILoggerFactory` |
| **Notification** | - Email, SMS, Push (FCM/APNs), Webhooks <br>- Queue‑backed delivery, retries | `INotificationService` |
| **File / Blob Storage** | - Abstracted bucket API (upload, version, signed URLs) | `IBlobStore` |
| **Scheduler / Background Jobs** | - Cron‑like tasks, queue workers, retry/back‑off policies | `IJobScheduler`, `IJobProcessor` |
| **Internationalization (i18n)** | - Message catalog, locale negotiation, runtime translation | `I18nService` |
| **API Gateway (optional)** | - Rate‑limit, request/response transformation, API‑key handling, request routing to modules | `IGatewayPlugin` |
| **Multitenancy (optional)** | - Tenant identification (sub‑domain, header, JWT claim) <br>- Tenant‑scoped data isolation primitives | `ITenantResolver`, `ITenantContext` |
> **Tip:** Pack each module as a **separate NPM/ Maven / NuGet / Go module** with its own `package.json` / `pom.xml` etc. The platform’s **bootstrapper** loads every module that implements `IModuleInitializer` (or similar) and calls `ConfigureServices` / `RegisterRoutes`.
---
## 4️⃣ EXTENSION‑POINT DESIGN (HOW PLUG‑INS HOOK IN)
1. **Module Manifest** – a tiny JSON/YAML file (`module.yaml`) that declares:
- Module name, version, dependencies (core ≥ 1.2.0, other modules)
- Public routes (e.g., `/api/v1/blog/**`)
- Required permissions (auto‑generated from source annotations)
- UI assets (static folder, React component entry point)
2. **Bootstrap Interface**
```ts
export interface IModuleInitializer {
/**
* Called during platform start‑up.
* Register services, routes, policies, background jobs.
*/
init(app: IApplicationBuilder, container: IServiceContainer): Promise<void>;
}
```
3. **Dependency Injection (DI) Conventions**
- Core registers **contracts** (`IUserRepository`, `IPermissionResolver`) as **singletons**.
- Modules register **implementations** with a **named scope** (e.g., `UserRepository:Local`).
- Override is possible via **module ordering** or explicit `container.override(...)`.
4. **Policy/Permission Extension**
```ts
// core lib
export type Permission = `${string}.${string}`; // e.g., "blog.post.create"
// module
export const BLOG_PERMS = {
POST_CREATE: 'blog.post.create',
POST_READ: 'blog.post.read',
POST_UPDATE: 'blog.post.update',
POST_DELETE: 'blog.post.delete',
} as const;
```
5. **Event Bus & Hooks**
- Central **topic**: `platform.*` (user.created, role.assigned, tenant.created)
- Modules can **publish** and **subscribe** via `IEventBus`.
- Provide **synchronous guard hooks** (`beforeUserCreate`, `afterRoleDelete`) for validation & side‑effects.
6. **UI Plug‑in System**
- Serve a **manifest** at `/modules` that front‑end bundles read to render navigation.
- Encourage **Web Component / Module Federation** pattern for SPA integration.

import { createApp } from '@core/app';
import { loadModules } from '@core/module-loader';
import { CoreModule } from '@core';
async function bootstrap() {
const app = await createApp();
// 1️⃣ Load core kernel (DI, config, logger)
await app.register(CoreModule);
// 2️⃣ Dynamically discover all `module.yaml` under /modules
const modules = await loadModules(__dirname + '/modules');
// 3️⃣ Initialise each module (order can be defined in manifest)
for (const mod of modules) {
await mod.instance.init(app.builder, app.container);
}
// 4️⃣ Start HTTP / gRPC server
await app.listen(process.env.PORT || 3000);
}
bootstrap().catch(err => {
console.error('❌ Platform failed to start', err);
process.exit(1);
});
```

## 6️⃣ KEY DECISIONS YOU MUST TAKE EARLY
| Decision | Options | Implications |
|----------|---------|--------------|
| **Language / Runtime** | Node.js (NestJS, Fastify), Java (Spring Boot), .NET (ASP.NET Core), Go (Gin/Fiber), Python (FastAPI) | Affects DI framework, module packaging, community libs for auth/OIDC, testing. |
| **Persistence Strategy** | Relational (PostgreSQL, MySQL) + optional NoSQL (Mongo, Dynamo) | Choose an ORM/Repository pattern that can be swapped per module. |
| **Auth Protocol** | JWT + Refresh, OAuth2 Authorization Server, OpenID Connect Provider, or integrate with external IdP (Keycloak, Auth0) | Influences token lifetimes, revocation strategy, multi‑tenant support. |
| **Event Bus** | In‑process EventEmitter (for monolith) → Kafka/Rabbit for scaling | Must expose both sync and async hooks. |
| **Module Packaging** | NPM packages (private registry) / Maven artifacts / Docker images (for micro‑service extraction) | Define a *semantic version* policy (core ≥ 1.0.0 never forces breaking changes on plug‑ins). |
| **Multitenancy Model** | Single DB with tenant_id column (shared), Schema‑per‑tenant, or DB‑per‑tenant | Affects repository base class and migrations tooling. |
| **Internationalisation** | i18next (frontend) + ICU messages in backend, or .NET Resource files | Choose a format that can be merged from modules at build time. |
| **CI/CD** | GitHub Actions + Docker Buildx + semantic‑release | Automate publishing of core + modules to same artifact registry. |
| **Testing Strategy** | Unit (Jest, JUnit, xUnit), Integration (Testcontainers), Contract (Pact) | Provide a **core testing harness** that loads a dummy module and asserts the contract of each extension point. |
---
## 7️⃣ COMMON PITFALLS & HOW TO AVOID THEM
| Pitfall | Symptoms | Fix / Guardrail |
|---------|----------|-----------------|
| **Tight coupling of modules to core implementation** | Module imports internal ORM classes, fails on core upgrade. | Expose **only interfaces** (`IUserRepository`) from core and keep the concrete implementation as a private package. |
| **Hard‑coded permission strings** | Duplicate names across modules, typos cause silent authorisation bypass. | Provide a **Permission Builder DSL** (`Permission.define('blog.post', ['create', 'read'])`) that generates constants and registers them automatically. |
| **Global state in modules** | Tests interfere with each other, memory leaks when hot‑reloading. | Enforce **stateless services**; keep per‑request scoped data (e.g., via DI context). |
| **Schema migrations clash** | Two modules try to add the same column or foreign key. | Adopt a **central migration orchestrator** (e.g., Flyway/DBMate) that loads migration scripts from each module in alphabetical order. |
| **Authorization checks omitted in new routes** | Security hole for new plug‑in routes. | Provide a **base controller class** that auto‑applies `Authorize` filter, or a compile‑time lint rule that checks every exported route for a permission annotation. |
| **Vendor lock‑in to a particular IdP** | Hard to replace Keycloak later. | Keep **IdP adapters** behind a `IIdentityProvider` interface; ship at least two (local DB + OIDC). |
| **Unbounded background jobs** | Queue overflow, OOM, duplicate processing. | Use a **job‑scheduler abstraction** that caps concurrency, persists state, and provides `@Retry` decorator. |
| **Insufficient observability** | You can’t tell which module caused latency spikes. | Tag every log/metric with `module=<moduleName>` automatically via middleware. |
| **Version drift between core and modules** | Module built against core 1.0 fails on core 1.5. | Publish a **core compatibility matrix** and enforce `peerDependencies` in package.json; CI should fail on mismatched ranges. |
---
## 8️⃣ QUICK START GUIDE (What to Build First)
1. **Create the Core Kernel**
- Set up DI container, config loader, logger, health/metrics endpoint.
- Scaffold `IUserRepository`, `IPermissionResolver`, `ITokenProvider`.
2. **Implement Identity & Auth**
- Choose JWT + Refresh + optional OpenID Connect.
- Add password hashing (bcrypt/argon2) and email verification flow.
3. **Add Role/Permission Engine**
- Simple RBAC matrix with an extensible `Permission` type.
- Provide a UI admin UI (or API only) to manage roles.
4. **Set Up Event Bus & Audit**
- Publish `user.created`, `role.granted` events.
- Store audit entries in an append‑only table (or log to Elastic).
5. **Build the Module Loader**
- Scan `modules/*/module.yaml`, load via `require()`/classpath.
- Register each `IModuleInitializer`.
6. **Create a Sample Feature Module** – e.g., **Blog**
- Define its own entities (`Post`, `Comment`).
- Register routes (`/api/v1/blog/posts`).
- Declare required permissions (`blog.post.create`).
7. **Write Integration Tests**
- Spin up an in‑memory DB (SQLite or H2).
- Load core + blog module, assert that a user without `blog.post.create` receives 403.
8. **Add CI Pipeline**
- Lint → Unit → Integration (Docker Compose with DB + Redis).
- On tag, publish `core` and `blog` packages to your private registry.
9. **Document Extension Points**
- Provide a **Developer Handbook** (README + `docs/extension-points.md`).
10. **Iterate** – add Notification, Scheduler, Multitenancy, API‑Gateway as needed.

## 9️⃣ TOOLS & LIBRARIES (starter suggestions per stack)
| Stack | Core | Auth | DI / Module | Event Bus | ORM | Validation | Testing |
|-------|------|------|-------------|-----------|-----|------------|---------|
| **Node (TypeScript)** | NestJS (or Fastify + `awilix`) | `@nestjs/passport`, `passport-jwt`, `openid-client` | NestJS dynamic modules or `@nestjs-modules/mailer` | `@nestjs/event-emitter` or `KafkaJS` | TypeORM / Prisma | `class-validator` + `class-transformer` | Jest + `supertest`, Testcontainers |
| **Java** | Spring Boot | Spring Security + `spring-boot-starter-oauth2-resource-server` | Spring Boot `@Configuration` + `ImportBeanDefinitionRegistrar` | Spring Cloud Stream (Kafka) | JPA / Hibernate | Bean Validation (Hibernate Validator) | JUnit5 + Testcontainers |
| **.NET 8** | ASP.NET Core | `Microsoft.AspNetCore.Authentication.JwtBearer` | `IHostedService` + `Scrutor` for module discovery | MassTransit (Rabbit/Kafka) | EF Core | FluentValidation | xUnit + DockerTestContainers |
| **Go** | Echo / Fiber | `golang.org/x/oauth2` + `github.com/golang-jwt/jwt/v5` | `uber-go/fx` for DI, module registration | `segmentio/kafka-go` | GORM / Ent | `go-playground/validator` | Testify + Dockertest |
| **Python** | FastAPI | `fastapi-users` / `Authlib` | `pluggy` (pytest plugins) or custom loader | `aiokafka` | SQLModel / Tortoise ORM | Pydantic | Pytest + pytest‑asyncio, Testcontainers |
Pick the stack you’re most comfortable with; the concepts stay identical.
---
## 🎉 TL;DR – What You Must Deliver
| Layer | Must‑have components | Why |
|-------|----------------------|-----|
| **Core Kernel** | Config, Logger, DI, Health, Metrics, Error Bus | Foundation for any module. |
| **Security** | Auth (JWT/OIDC), Authorization (RBAC + ABAC), Audit | Guarantees secure, traceable access. |
| **User & Role Management** | User CRUD, Password reset, Role ↔ Permission matrix | The “identity” piece everyone will reuse. |
| **Extension System** | `IModuleInitializer`, `module.yaml`, EventBus, Permission DSL | Enables plug‑ins without touching core. |
| **Infrastructure Adapters** | DB repo, Cache, Queue, Blob storage, Email/SMS | Keeps core agnostic to any concrete tech. |
| **Observability** | Structured logs, Prometheus metrics, OpenTelemetry traces | You can monitor each module individually. |
| **DevOps Boilerplate** | CI pipelines, Dockerfiles, Semantic‑release, Docs | Makes the framework production‑ready out‑of‑the‑box. |
| **Sample Feature Module** | (e.g., Blog) to show how to add routes, permissions, DB entities | Provides a reference implementation for future developers. |
When you scaffold those pieces **once**, any downstream team can drop a new folder that follows the `module.yaml` contract, implement the initializer, add its own tables & APIs, and instantly get:
* secure authentication,
* role‑based authorization,
* logging/metrics,
* unified config,
* CI‑ready testing,
* optional multi‑tenant isolation.
That’s the foundation of a **robust, future‑proof platform boilerplate**. Happy building! 🚀

type ConfigProvider interface {
Get(key string) any
Unmarshal(v any) error
GetString(key string) string
GetInt(key string) int
GetBool(key string) bool
GetStringSlice(key string) []string
}
```
3. Add package documentation
4. Export interface for use by modules
## Acceptance Criteria

- **Section**: 0.2 Configuration System
- **Status**: Pending
- **Priority**: High
- **Estimated Time**: 30 minutes
- **Dependencies**: 0.2.1, 0.2.2
## Description
Implement the Viper-based configuration loader in `internal/config/` that implements the `ConfigProvider` interface. This loader will handle hierarchical configuration loading from files and environment variables.
## Requirements
- Implement `ConfigProvider` interface using Viper
- Load configuration in order: defaults → environment-specific → env vars
- Support YAML configuration files
- Support environment variable overrides
- Provide placeholder for secret manager integration (Phase 6)
## Implementation Steps
1. Create `internal/config/config.go`:
- Implement `ConfigProvider` interface
- Wrap Viper instance
- Implement all interface methods
2. Create `internal/config/loader.go`:
- `LoadConfig()` function
- Load `config/default.yaml` as baseline
- Merge environment-specific YAML (development/production)
- Apply environment variable overrides
- Set up automatic environment variable binding
3. Add error handling for missing config files
4. Add logging for configuration loading
## Acceptance Criteria
- [ ] `internal/config/config.go` implements `ConfigProvider`
- [ ] `internal/config/loader.go` has `LoadConfig()` function
- [ ] Configuration loads from `config/default.yaml`
- [ ] Environment-specific configs are merged correctly
- [ ] Environment variables override file values
- [ ] Errors are handled gracefully
## Related ADRs
- [ADR-0004: Configuration Management](../../adr/0004-configuration-management.md)
## Implementation Notes
- Use Viper's `SetConfigName()` and `AddConfigPath()`
- Use `MergeInConfig()` for environment-specific files
- Use `AutomaticEnv()` for environment variable binding
- Set environment variable prefix (e.g., `GOPLT_`)
- Use `SetEnvKeyReplacer()` to replace dots with underscores
