# Phase 4: Sample Feature Module (Blog)

## Overview
Create a sample blog module to demonstrate the module framework. This module will implement blog posts with CRUD operations, showing how to build a feature module that integrates with the core platform.

## Tasks

### 4.1 Module Setup
- [4.1.1 - Create Blog Module Directory](./4.1.1-create-modulesblog-directory.md)
- [4.1.2 - Initialize Go Module](./4.1.2-initialize-gomod.md)

### 4.2 Module Configuration
- [4.2.1 - Create Module Manifest](./4.2.1-create-modulesblogmoduleyaml.md)

### 4.3 Domain Layer
- [4.3.1 - Create Post Domain Model](./4.3.1-create-modulesbloginternaldomainpostgo.md)
- [4.3.2 - Create Ent Schema](./4.3.2-create-modulesbloginternalentschemapost.md)
- [4.3.3 - Generate Ent Code](./4.3.3-generate-ent-code-for-blog-module.md)

### 4.4 Repository Layer
- [4.4.1 - Create Post Repository Interface](./4.4.1-create-modulesbloginternaldomainpost_repogo.md)
- [4.4.2 - Implement Repository](./4.4.2-implement-using-ent-client-shared-from-core.md)

### 4.5 Service Layer
- [4.5.1 - Create Post Service](./4.5.1-create-modulesbloginternalservicepost_servicego.md)

### 4.6 API Layer
- [4.6.1 - Create API Handler](./4.6.1-create-modulesbloginternalapihandlergo.md)
