REST APIs with Express

Express.js is a popular Node.js framework ideal for building RESTful APIs. REST APIs utilize HTTP methods to interact with resources efficiently. Before building APIs with Express, a basic understanding of Node.js, JavaScript, and REST concepts is crucial. Express simplifies API creation with robust routing, handling requests for specific resources. Its advantages include simplicity, scalability due to Node.js's non-blocking I/O, and a large community with extensive documentation. Middleware support allows extending functionality for tasks like authentication. However, error handling can be complex, and it lacks a built-in ORM, requiring integration of external tools. Large applications can become complex, demanding careful structuring. Overall, Express.js is a powerful tool for building REST APIs, suitable for projects of varying sizes. Developers should consider its limitations regarding error handling and large-scale scaling.
