This repository contains the complete code for the FastAPI - A Python Framework | Full Course tutorial on YouTube. The project demonstrates how to build a robust backend API using FastAPI, covering everything from basic setup to authentication, database integration, and deployment.

📚 About the Project

This project is a hands-on implementation of a blog API using FastAPI. It covers essential backend development concepts such as routing, request/response handling, database models, authentication with JWT, and more. The codebase is structured for clarity and scalability, making it a great reference for both beginners and intermediate Python backend developers.

🗂️ Codebase Structure

How the Codebase Works

This project follows a modular and scalable structure, making it easy to maintain and extend. Here’s how the main components interact:

• main.py
  The entry point of the application. It creates the FastAPI app instance and includes routers for different parts of the API (such as blogs and users).

• routers/
  Contains route definitions for different resources.

  • routers/blog.py: Defines the API endpoints for blog operations (CRUD).
  • routers/user.py: Defines the API endpoints for user operations.
  • routers/authentication.py: Handles authentication-related endpoints (e.g., login).

• repository/
  Contains the business logic and database operations.

  • repository/blog.py: Implements the core logic for blog-related actions (e.g., create, read, update, delete blogs).
  • repository/user.py: Implements the logic for user-related actions.

• models.py
  Defines the SQLAlchemy models for the database tables.

• schemas.py
  Contains Pydantic models for request and response validation.

• database.py
  Sets up the database connection and session.

• hashing.py
  Handles password hashing and verification.

• JWTtoken.py
  Manages JWT creation for authentication.

• oauth2.py
  Handles OAuth2 authentication logic.

This separation of concerns ensures that:

• Routes (in routers/) only handle HTTP request/response and delegate business logic.
• Business logic (in repository/) is reusable and testable.
• Models and schemas keep data validation and database structure organized.

Example flow:
A request to a blog endpoint is routed from main.py to routers/blog.py, which then calls the appropriate function in repository/blog.py to interact with the database and return a response.

🧑‍💻 API Overview

The project implements a RESTful API for a blog platform, including:

• Authentication: JWT-based login
• Blogs: CRUD operations (create, read, update, delete)
• Users: User registration and retrieval

Example: Swagger UI

🚀 Getting Started

1. Clone the repository:

   git clone https://github.com/<your-username>/FastAPI-Backend-Course.git
   cd FastAPI-Backend-Course

2. Create and activate a virtual environment:

   python -m venv blog-env
   # On Windows:
   blog-env\Scripts\activate
   # On macOS/Linux:
   source blog-env/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

4. Run the FastAPI server:

   uvicorn blog.main:app --reload

5. Access the API docs:
