Build a RESTful API with Node.js and Express - Build a Production-Grade API with Node and PostgreSQL

Node.js API development and Express RESTful API. Build a RESTful API with Node.js and Express. Learn Node.js API development. From your first route to a production-ready service, this hands-on guide covers validation, authentication, error handling, and a real database. Whether you're a beginner or aspiring pro, Hugo Kessler walks you through every step. Unlike Web Design with HTML, CSS, JavaScript and jQuery Set or JavaScript and jQuery: Interactive Front-End Web Development, this book focuses solely on backend API creation with Node.js and Express. Start by setting up your environment and creating a basic Express server. Then add routes, middleware, and request validation. Implement JWT-based authentication and secure endpoints. Integrate MongoDB or PostgreSQL for persistent data storage. Handle errors gracefully with custom error classes and global handlers. Write unit and integration tests with Jest and Supertest. Deploy your API to cloud platforms like Heroku or AWS. By the end, you'll have a production-ready API with logging, rate limiting, and documentation. Each chapter includes practical exercises and real-world scenarios. You'll learn to structure code for scalability, use environment variables, and manage dependencies. The book also covers API versioning, pagination, and caching. No prior Node.js experience required—just basic JavaScript knowledge. Perfect for web developers transitioning to backend, or beginners wanting a solid foundation. Competing books like Learning Web Design: A Beginner's Guide to HTML, CSS, JavaScript, and Web Graphics or A Software Engineer Learns HTML5, JavaScript and jQuery focus on frontend or general web development. This book is laser-focused on building APIs with Node.js and Express. Also compare with JavaScript from Beginner to Professional which covers JavaScript broadly but not API development.
