Organizing your Express.js project structure for better productivity

Express.js, a popular Node.js framework, is known for its speed, minimalism, and flexibility, making it a preferred choice for web development by companies like Accenture, IBM, and Uber. Despite its advantages, Express lacks a predefined project structure, which can lead to challenges in maintaining consistency and organization, especially within a team setting. The article outlines a recommended project structure for Express applications to promote productivity and maintainability, emphasizing the importance of organizing the code into distinct folders for configuration, controllers, middleware, routes, models, services, and utilities. It also suggests maintaining a separate folder for tests, mirroring the source code structure, to ensure comprehensive coverage. This structured approach aids in minimizing guesswork and enhancing code predictability across team members. An example project utilizing Node.js and MySQL is provided to demonstrate this organizational strategy, highlighting the benefits of an opinionated structure within the otherwise unopinionated framework of Express.js.
