In the very first recipe of this cookbook, Setting up a router, we explored various ways to set up routing in Node. Express provides a far superior and very powerful routing interface which we'll explore in this recipe.
Let's say we want to add a page for a fictional character by the name of Mr Page. We'll name the route page
, so in the routes
section of app.js
we add the following code:
app.get('/page', function (req, res) { res.send('Hello I am Mr Page'); });
We can also define flexible routes, and grab the requested route using req.params
, like so:
app.get('/:page', function (req, res) { res.send('Welcome to the ' + req.params.page + ' page'); });
It's okay to throw our callbacks directly into app.get
while developing, but in the interest of a clutter-free app.js
let's take our callbacks and load them from routes/index.js
as follows:
exports.index = function(req, res){ res.render('index', { title: 'Express...
