Other environments

  1. xpress.js (Node.js): PREFERRED
    • Express.js is a widely used Node.js web application framework that allows you to create robust and scalable web applications. It provides a powerful and flexible routing system, making it easy to handle HTTP methods like GET, PUT, POST, and DELETE.While Express.js itself does not natively support WebSockets, you can easily integrate WebSocket functionality using libraries like or ws alongside Express.js for real-time communication.
  2. Flask (Python):
    • Flask is a lightweight Python web framework that is easy to use and extend. It supports routing and allows you to handle GET, PUT, POST, and DELETE HTTP methods with ease.
    • For WebSocket support in Flask, you can use libraries like Flask-SocketIO or Flask-Socket-Redis to implement real-time features.
  3. ASP.NET Core (C#):
    • ASP.NET Core is a high-performance, cross-platform framework for building modern, cloud-based, and internet-connected applications. It provides a robust web server framework that can handle HTTP methods like GET, PUT, POST, and DELETE.
    • ASP.NET Core also offers SignalR, a library for real-time web functionality that includes WebSocket support for building interactive, real-time applications.
