How to create a solid Express.js app structure

Creating a solid Express.js app structure involves following best practices and principles of software design. Here are some key steps to help you organize your Express.js application effectively:



Define a clear folder structure: Start by defining a clear folder korea phone number structure for your Express.js application. Create separate folders for routes, controllers, models, views, middleware, public assets, and configuration files. This will help you locate and manage your code more efficiently.

Separate concerns: Follow the principle of separation of concerns by dividing your code into distinct modules based on their functionality. For example, separate your route handling logic from your business logic by creating separate files for routes and controllers.




Use middleware effectively: Middleware functions in Express.js are a powerful way to intercept and modify incoming requests. Use middleware to handle common tasks such as authentication, error handling, logging, and data validation. By splitting your middleware logic into separate modules, you can keep your codebase clean and modular.
