Node.js, Express: url handling, how to implement?

Question

Node.js

Hello, tell me please. Django handles urls nicely

urlpatterns = [
    url(r'^articles/2003/$', 'news.views.special_case_2003'),
    url(r'^articles/([0-9]{4})/$', 'news.views.year_archive'),
    url(r'^articles/([0-9]{4})/([0-9]{2})/$', 'news.views.month_archive'),
    url(r'^articles/([0-9]{4})/([0-9]{2})/([0-9]+)/$', 'news.views.article_detail'),
]

Is there such possibility in Node.js in Express or other framework. And how can this be done (article, example)? Thanks for your help and your time.

Have a look at this Express help section. It describes just that - how to set a controller for the url.
A few examples:
1) default index page handler:

app.get('/articles/2003/', function(req, res){
  res.send('articles in 2003 year');
});

2) Using Regex to validate url:

app.get(/^\/articles\/([0-9]{4})\/$/, function(req, res){
  res.send('articles in ' + req.params[0] + ' year');
});

3) Using format in url:

app.get('/user/:id', function(){
  // ... 
})

4) You can set the handler without specifying the inline function by placing the controllers in a separate file. So it will be even more like a subject:

var controllers = require('./controllers');
app.get('/articles/2003/', controllers.special_case_2003);
app.get(/^\/articles\/([0-9]{4})\/$/, controllers.year_archive);
app.get('/user/:id', controllers.user);

The controllers.js file describes the handler functions for each of the urls.
