router.route(path)
Returns an instance of a single route which you can then use to handle HTTP verbs with optional middleware. Use router.route() to avoid duplicate route naming and thus typo errors.
Building on the router.param() example above, the following code shows how to use router.route() to specify various HTTP method handlers.
var router = express.Router();
router.param('user_id', function(req, res, next, id) {
// sample user, would actually fetch from DB, etc...
req.user = {
id: id,
name: 'TJ'
};
next();
});
router.route('/users/:user_id')
.all(function(req, res, next) {
// runs for all HTTP verbs first
// think of it as route specific middleware!
next();
})
.get(function(req, res, next) {
res.json(req.user);
})
.put(function(req, res, next) {
// just an example of maybe updating the user
req.user.name = req.params.name;
// save user ... etc
res.json(req.user);
})
.post(function(req, res, next) {
next(new Error('not implemented'));
})
.delete(function(req, res, next) {
next(new Error('not implemented'));
});
This approach re-uses the single /users/:user_id path and add handlers for various HTTP methods.
NOTE: When you use router.route(), middleware ordering is based on when the route is created, not when method handlers are added to the route. For this purpose, you can consider method handlers to belong to the route to which they were added.
