User & Post Backend API

This is a full-fledged RESTful backend for managing Users and Posts (Articles), strictly following OOP principles with TypeScript, Express, and Mongoose.

Features

1. User Management (OOP)

• Create User: Add new users with name, email, role.
• Read Users: Get list of all users or single user by ID.
• Update User: Modify user details.
• Delete User: Remove users.

2. Post Management

• Create Post: Add new articles with title, content, author.
• Read Posts: Get all posts or single post.
• Update Post: Edit post title or content.
• Delete Post: Remove posts.
• (Note: Refactored from previous 'Todo' codebase).

Architecture

The project follows the Controller-Service-Model pattern:

• Models (src/models/): Database Schemas & Interfaces (user.model.ts, post.model.ts).
• Services (src/services/): Business Logic layers (user.service.ts, post.service.ts).
• Controllers (src/controllers/): Request handlers (user.controller.ts, post.controller.ts).
• Routes (src/routes/): API Endpoint definitions (user.routes.ts, post.routes.ts).
