Building REST APIs with Node.js

Build APIs That Actually Work in Production

Most API tutorials teach you how to return JSON from an endpoint. This course teaches you how to build APIs that handle real traffic, real users, and real problems — the kind you'll face on the job.

From your first Express route to deploying a production-ready API, you'll learn every layer of the stack: routing, middleware, validation, authentication, database integration, testing, and deployment.

What You'll Build

Throughout this course, you'll build a complete REST API from scratch. Not a toy project — a properly structured API with authentication, input validation, error handling, pagination, and tests.

Topics Covered

• Express fundamentals — routing, middleware chains, request/response lifecycle
• Input validation with Zod — never trust user input, validate everything
• Database integration — Drizzle ORM with SQLite, CRUD operations, transactions
• JWT authentication — secure your endpoints with industry-standard tokens
• Security hardening — rate limiting, CORS, security headers with Helmet
• Testing — unit tests with Vitest, integration tests with Supertest
• Deployment — environment config, process management, CI/CD basics

Who Should Take This Course?

This course is designed for developers who know JavaScript and want to build backend services. If you've built frontends but never created your own API, this is the perfect next step.

You should be comfortable with JavaScript basics — functions, async/await, and working with objects. No backend experience required.

Why Node.js for APIs?

Node.js lets you use the same language on both frontend and backend. Its non-blocking I/O model handles concurrent requests efficiently, and the npm ecosystem gives you battle-tested libraries for every common backend task.

Express is the most widely-used Node.js web framework for a reason — it's minimal, flexible, and has a massive community. The patterns you learn here will transfer to any Node.js framework.
