Building Scalable APIs with Node.js and Express
Scaling a backend is not just about more servers; it's about better architecture. Node.js provides a non-blocking I/O model that makes it ideal for handling thousands of concurrent connections.
Working with Express.js allows us to build robust routing systems quickly. However, as the application grows, we must look into horizontal scaling, caching strategies (like Redis), and database optimization to keep response times low.
Modular Design
Keeping your controllers, routes, and services separate is essential. This separation of concerns not only makes the code more testable but also allows different parts of the team to work on different modules without conflicts.
