params in nodejs code example

Example 1: req.params req.query

req.params contains route parameters (in the path portion of the URL), 
and req.query contains the URL query parameters (after the ? in the URL).

You can also use req.param(name) to look up a parameter in both places (as well as req.body),

Example 2: node.js parameters

app.get('/index/profile/:id', function (req, res) {
  res.end('profile with id' + req.params.id)
});
