Building Scalable APIs with Express & TypeScript.

Building scalable APIs requires a solid foundation. Express.js is one of the most popular frameworks for Node.js, but when combined with TypeScript, it becomes even more powerful. With TypeScript, you get type-safety, autocompletion, and improved developer experience. In this article, we will cover project structure, environment variables, middleware, controllers, error handling, and database integration. Additionally, you will learn best practices for securing your API, logging, and performance monitoring to ensure your app can handle real-world traffic.
