Routing is the process of defining paths in a web application to handle different requests. Here's a quick guide to understanding and implementing routing effectively:

🧭 What is Routing?

Routing determines how an application responds to a client request based on the URL path and HTTP method.
For example:

  • /about → GET → Display a static page
  • /api/data → POST → Process data submission

🛠️ Common Routing Implementations

  • Express.js (Node.js): Use app.get(), app.post() etc. 
    app.get('/en/tutorials/web_application-routing', (req, res) => {
  res.send('Routing Tutorial Page');
});
  • Flask (Python): Define routes with @app.route()
  • Spring Boot (Java): Use @RequestMapping or @GetMapping
