ExpressJS features and specs

  • Fast Setup
    ExpressJS provides a minimal and flexible framework that allows rapid setup and development of web and mobile applications.
  • Middleware Support
    ExpressJS has a robust middleware system, allowing developers to add reusable functions to the request-handling pipeline.
  • Extensibility
    ExpressJS is highly extensible through third-party libraries and built-in functionality, catering to the needs of various applications.
  • Performance
    Due to its minimalist core, ExpressJS provides efficient performance and is capable of handling a high number of requests per second.
  • Community and Ecosystem
    A large and active community provides extensive documentation, support, and a wide array of open-source packages to extend functionality.

Possible disadvantages of ExpressJS

  • Minimalist Core
    The minimalist nature of ExpressJS may require additional time and effort to integrate required plugins and libraries for specific features.
  • Learning Curve
    While ExpressJS is straightforward, mastering the middleware pattern and effective usage can have a learning curve for new developers.
  • Callback Hell
    Developers can encounter 'callback hell' due to nested callback functions, though this can be mitigated using Promises and async/await in modern JavaScript.
  • Lack of Convention
    Unlike opinionated frameworks, ExpressJS lacks conventions, which can lead to inconsistent code structure and maintenance challenges across different projects.
  • Security
    ExpressJS does not have built-in security features and relies on third-party solutions, requiring developers to be vigilant about applying best security practices.
  • Scalability
    While ExpressJS can handle high traffic, building and maintaining a highly scalable application might require significant additional effort, particularly in terms of codebase organization and resource management.

  • Not a Middy Fan
    Express.js was created around the time callbacks were _the_ architecture in Node.js. The world, including UI, quickly found callbacks do not compose well, and void return values are hard to test because of side-effects. Promises were created so you could compose functions, but still have control where your side-effects go. This negates the need for middlewares / callbacks. - Source: dev.to / 19 days ago
