JavaScript Backend Development: Build APIs with Express and Swagger

Building a modern application requires a robust, secure, and well-documented backend. If you know basic JavaScript, you are already halfway to creating powerful server-side applications that connect databases, handle authentication, and power frontend clients. In this course, you will transition from writing simple scripts to architecting production-ready REST APIs. You will gain a deep understanding of how servers process requests, store data securely, manage user sessions, and integrate third-party services like payment gateways and cloud media storage. What you'll learn: - Understand foundational backend concepts, HTTP methods, and request-response cycles. - Build secure RESTful APIs using Express, Node.js, and MongoDB with structured error handling. - Configure modern authentication flows using JSON Web Tokens (JWT), sessions, and secure cookies. - Document your APIs professionally using Swagger so frontend teams can easily consume your endpoints. - Integrate third-party services for cloud file uploads with Cloudinary and process mock payments. - Apply modern security practices, environment variable management, and data validation to protect your application. You will start by exploring the core architecture of backend systems before moving step-by-step through database integration, user authentication, and API documentation. Through written explanations and practical code scenarios, you will learn to structure clean, maintainable backend code. This course is designed for aspiring backend developers and frontend engineers who have a basic understanding of JavaScript and want to learn server-side development from the ground up.
