Building Backend APIs with Node.js and Express

О курсе

This course teaches learners how to build modern backend APIs using Node.js and Express.js, helping them move from basic server-side programming to structured, scalable API development. You'll begin by understanding why frameworks are used in backend development and how Express simplifies the process of building web applications. You will explore the limitations of the native Node.js HTTP module, learn the role of Express in modern backend systems, and create your first Express application with routes, endpoints, route parameters, and query parameters. The course then moves into middleware architecture, where you'll learn how middleware supports request processing, validation, logging, and application flow. From there, you'll design RESTful APIs using clean endpoint structures, HTTP methods, status codes, and consistent response patterns. You will also implement CRUD operations, validate incoming requests, and create centralized error handling for reliable backend applications. Finally, you'll connect Express APIs to MongoDB using Mongoose. You will learn how databases support backend applications, create schemas and models, and perform database CRUD operations directly from API endpoints. By the end of this course, you will be able to: - Explain how Express.js simplifies backend API development. - Create Express applications with routes, endpoints, parameters, and middleware. - Apply REST API design principles using HTTP methods, status codes, and response structures. - Build CRUD APIs that create, read, update, and delete resources. - Implement request validation and centralized error handling in Express applications. Designed for learners who understand basic Node.js concepts and want to build real backend APIs, this course is ideal for aspiring backend developers, JavaScript developers, and software engineering students. A basic understanding of JavaScript, Node.js fundamentals, npm, and asynchronous programming will help you get the most from this course. Build your first complete REST API workflow and learn how Express.js brings structure, speed, and scalability to Node.js backend development.
