How does URL routing work in different web frameworks?

URL routing is the process of mapping URLs to specific handlers or controllers in web frameworks. Different frameworks have their own conventions and methods for defining routes.

Can you give me examples of routing in Express and Django?

In Express, you define routes using app.get() or app.post() methods. For example:

app.get('/users', (req, res) => {
  res.send('User list');
});

In Django, you define routes in the urls.py file using the path() function:

from django.urls import path
from . import views

urlpatterns = [
    path('users/', views.user_list),
]

What about routing in Flask?

In Flask, you use the @app.route decorator to define routes. For example:

@app.route('/users')
def user_list():
    return 'User list'

Are there any best practices for URL routing?

Yes, some best practices include using RESTful conventions, keeping URLs simple and descriptive, and avoiding deep nesting of routes.
