Learn FastAPI from scratch with PostgreSQL, SQLAlchemy, JWT, testing, and Docker by building a real e-commerce API.
What you'll learn
Build a complete e-commerce REST API from scratch using Python and FastAPI. Design maintainable FastAPI applications using routers, schemas, database models, configuration, and dependency injection. Create and validate REST endpoints using path parameters, query parameters, request bodies, response models, and Pydantic. Connect FastAPI to PostgreSQL with SQLAlchemy and implement CRUD operations, database sessions, and table relationships. Manage database schema changes by creating, applying, and reversing Alembic migrations. Implement secure registration and login with password hashing, JWT authentication, current-user dependencies, and protected routes. Create role-based authorization that provides different permissions for administrators and customers. Develop product and category management with search, filtering, sorting, pagination, and product-image uploads. Build complete shopping-cart, order-processing, order-history, order-status, and stock-management workflows. Handle validation errors, custom exceptions, CORS, environment variables, and common REST API security risks. Write automated tests with Pytest for API endpoints, authentication, database operations, shopping carts, and orders. Containerize FastAPI and PostgreSQL with Docker Compose and prepare the e-commerce API for production deployment.Requirements
Basic knowledge of Python, including variables, functions, classes, lists, and dictionaries. A willingness to code along and practice.Description
Learn FastAPI from the ground up by building a complete, real-world e-commerce REST API with Python, PostgreSQL, SQLAlchemy, JWT authentication, Docker, and deployment.
This is a practical, project-based course. You will begin with the fundamentals of APIs and FastAPI, then gradually develop a structured e-commerce backend containing products, categories, users, authentication, shopping carts, orders, stock management, image uploads, and more.
Instead of learning disconnected concepts, you will see how each feature fits into a complete backend application.
What You Will Build
By the end of the course, you will have created a complete e-commerce REST API featuring
User registration and login Secure password hashing JWT authentication Protected API endpoints Admin and customer roles Role-based authorization Product and category management Product search, filtering, sorting, and pagination Shopping-cart management Order creation and order history Product stock management PostgreSQL database integration SQLAlchemy models and relationships Alembic database migrations Docker and Docker Compose configuration Interactive Swagger and ReDoc documentation Production deployment preparationYour Step-by-Step Learning Journey
1. Understand Web and API Fundamentals
You will first understand how the web works, including HTTP requests, responses, methods, status codes, headers, JSON, APIs, and REST API principles. You will also learn how to test APIs using tools such as Postman or Insomnia.
2. Create Your First FastAPI Application
You will install FastAPI and Uvicorn, create your first application, run a development server, build API endpoints, return JSON responses, and explore automatic documentation using Swagger UI and ReDoc.
3. Work With Requests and Data Validation
You will learn how to use path parameters, query parameters, request bodies, response models, nested schemas, validation rules, optional values, and constraints using Pydantic.
4. Structure a Professional FastAPI Project
You will organize the application using routers, schemas, models, configuration files, environment variables, and dependency injection. This structure will make the project easier to maintain, test, and extend.
5. Connect FastAPI to PostgreSQL
You will connect the application to PostgreSQL using SQLAlchemy and Psycopg. You will create database models, manage sessions, implement CRUD operations, handle database errors, and build relationships between tables.
6. Manage Database Migrations
You will use Alembic to create, apply, update, and reverse database migrations safely as the application evolves.
7. Build the Product System
You will create products and categories, implement complete CRUD operations, and add practical features such as search, filtering, pagination, and sorting.
8. Add Authentication and Authorization
You will build user registration and login, hash passwords securely, generate and validate JWT access tokens, protect endpoints, retrieve the current user, and control access using admin and customer roles.
9. Develop Shopping Cart and Order Features
You will create cart and cart-item models, add products to a cart, update quantities, remove items, place orders, preserve product-price snapshots, manage order history, update order statuses, and control product stock.
10. Improve Security and Error Handling
You will handle HTTP and validation errors, create custom exception handlers, configure CORS, protect environment variables, understand SQL injection prevention, and learn about common API security mistakes.
11. Add File Uploads and Extra Features
You will implement product image uploads, validate uploaded files, serve static files, work with background tasks, and understand email-sending workflows.
12. Dockerize and Deploy the API
You will create a Dockerfile, configure Docker Compose, run FastAPI with PostgreSQL, manage production environment variables and migrations, inspect logs, and prepare the application for deployment.
What You Will Gain
After completing this course, you will be able to
Build modern REST APIs using Python and FastAPI Design maintainable backend project structures Validate request and response data with Pydantic Work confidently with PostgreSQL and SQLAlchemy Design relational database models Manage schema changes with Alembic Implement secure JWT authentication Create role-based authorization systems Develop real-world shopping-cart and order workflows Containerize backend applications with Docker Document and prepare APIs for production deployment Create a portfolio-ready backend projectPrerequisites
To follow this course, you should have
Basic knowledge of Python A willingness to code along and practiceYou donot need previous experience with FastAPI, PostgreSQL, SQLAlchemy, Alembic, JWT. These technologies are introduced step by step throughout the course.
