Node.js API Development: Build and Test RESTful APIs with Express and MongoDB

Modern web and mobile applications rely heavily on robust backends to manage data and power user experiences. Building these backend systems requires a solid understanding of how to design secure, scalable, and fully tested APIs. This text-based course guides you through the process of building professional RESTful APIs using Node.js, Express, and MongoDB. You will transition from understanding core backend concepts to writing clean, maintainable server-side code, implementing robust security measures, and writing automated tests to ensure your application runs flawlessly. What you'll learn: - Understand the foundational concepts of Node.js, asynchronous programming, and the MVC architectural pattern. - Build functional RESTful endpoints using Express for routing, middleware integration, and request handling. - Configure MongoDB databases using Mongoose to model data, run queries, and manage relationships. - Implement secure authentication, authorization mechanisms, and data sanitization to protect your application. - Apply modern testing practices by writing unit and end-to-end (E2E) tests for backend routes. - Manage advanced API features like pagination, filtering, sorting, and file uploads using modern ES Modules syntax. The course starts with fundamental backend concepts and database setup before moving into hands-on API construction. You will then progress to advanced topics such as security, global error handling, automated testing, and preparing your application for deployment. This course is designed for beginners eager to learn backend development, frontend developers looking to transition to the full stack, and anyone interested in mastering API design. No prior backend experience is required, though a basic understanding of JavaScript is helpful. Start reading today to build your foundation in server-side development and automated API testing.
