Checking out the Express.JS API Reference
A myriad of HTTP utility methods it says. Thinking about HTTP verbs and the syntax
app.get('/', function(req, res){
res.send('hello world');
});
which is about all I really know at this point, let's dig in and see how Express
is put together to extend node.JS with a robust set of features.
app.routes
The app.routes object houses all of the routes defined mapped by the associated HTTP verb. This object may be used for introspection capabilities, for example Express uses this internally not only for routing but to provide default OPTIONS behaviour unless app.options() is used. Your application or framework may also remove routes by simply by removing them from this object.
console.log(app.routes)
{ get:
[ { path: '/',
method: 'get',
callbacks: [Object],
keys: [ ],
regexp: /^\/\/?$/i },
{ path: '/user/:id',
method: 'get',
callbacks: [Object],
keys: [{ name: 'id', optional: false }],
regexp: /^\/user\/(?:([^\/]+?))\/?$/i } ],
delete:
[ { path: '/user/:id',
method: 'delete',
callbacks: [Object],
keys: [Object],
regexp: /^\/user\/(?:([^\/]+?))\/?$/i } ] }While I'm here I want to make a note on serving files from multiple directories because I think this is a good thing.
app.use(express.static(__dirname + '/public'));
app.use(express.static(__dirname + '/files'));
app.use(express.static(__dirname + '/uploads'));
