How do I handle route parameters in different web frameworks?

Handling route parameters varies by framework. Are you looking for examples in specific frameworks like Express, Django, or Flask?

Yes, can you explain how to do it in Express?

In Express, you can define route parameters using a colon. For example, app.get('/user/:id', (req, res) => { ... }) allows you to access the id parameter via req.params.id.

What about in Django?

In Django, you define route parameters in your URL patterns. For example, path('user/<int:id>/', views.user_detail) allows you to access the id in your view function.

Can you give me an example in Flask?

Sure! In Flask, you can use route parameters like this: @app.route('/user/<int:id>') and access the id with request.view_args['id'].
