By Technoupskills – Create Fast, Scalable & Secure Web APIs

Learn to build modern, efficient, and RESTful APIs using Node.js and Express.js. This course is essential for backend and full stack developers who want to power frontend apps (like React, Angular, Flutter) with a solid server-side foundation.

🔥 What You’ll Learn

✅ RESTful API principles & architecture
✅ CRUD operations using Node.js & Express
✅ Connecting APIs to MongoDB with Mongoose
✅ Authentication using JWT
✅ API request handling & error management
✅ Building scalable backend services
✅ Postman for testing APIs

📚 Course Curriculum

Module 1: Introduction to REST & APIs

• What is an API?

• REST vs SOAP vs GraphQL

• Understanding endpoints, HTTP methods (GET, POST, PUT, DELETE)

• JSON as a data format

Module 2: Setting Up the Server

• Installing Node.js and Express

• Project structure & environment setup

• Creating your first API route

• Using Nodemon for development

Module 3: Routing & Controllers

• Defining routes for resources

• Route parameters & query strings

• Controller functions for clean architecture

• Handling status codes (200, 201, 400, 404, 500)

Module 4: CRUD with MongoDB & Mongoose

• Connecting to MongoDB using Mongoose

• Creating models and schemas

• API endpoints for Create, Read, Update, Delete

• Using async/await for DB operations

• Error handling in DB operations

Module 5: Middleware & Validation

• Creating custom middleware

• Express built-in middleware

• Input validation using express-validator

• Logging requests with morgan

Module 6: Authentication & Authorization

• Register/Login endpoints

• Hashing passwords with bcrypt

• JWT (JSON Web Token) authentication

• Securing routes using middleware

• Role-based access control (admin/user)

Module 7: Advanced REST API Features

• Pagination, sorting, and filtering

• Rate limiting & security (Helmet, CORS)

• File uploads (using Multer)

• Building nested routes (e.g., comments on posts)

Module 8: API Testing & Deployment

• Using Postman to test endpoints

• Writing sample API documentation

• Deploying to Render / Cyclic

• Using environment variables with dotenv

🎓 Who Should Take This Course?
