Before, after and around
|
|
========================
|
|
|
|
The `before`, `after` and `around` methods can easily be replaced by middleware:
|
|
|
|
Old:
|
|
|
|
```js
|
|
let start;
|
|
ctrl.before(function (req, res) {
|
|
start = Date.now();
|
|
});
|
|
ctrl.after(function (req, res) {
|
|
console.log('Request handled in ', (Date.now() - start), 'ms');
|
|
});
|
|
```
|
|
|
|
New:
|
|
|
|
```js
|
|
router.use(function (req, res, next) {
|
|
let start = Date.now();
|
|
next();
|
|
console.log('Request handled in ', (Date.now() - start), 'ms');
|
|
});
|
|
```
|
|
|
|
Note that unlike `around` middleware receives the `next` function as the *third* argument (the "opts" argument has no equivalent).
