Question

I am redirecting to a page using ``` res.redirect('/pageOne'); ``` so after the redirect i want call a function , But when i called the function ``` res.redirect('/pageOne'); callBack(); ``` I found that the callBack executed before the redirect, so there any way to pass callBack to redirect ? according to the api its no. any other workaround ?

Accepted Answer

According to the current implementation, there is no way to pass a callback into the `redirect` method. However, since the response object `res` inherits from Node's own `ServerResponse`, which in turn is a `Writable` stream, you can watch for the related events. For example, you might try the `finish` event:

Event: 'finish'

When `end()` is called and there are no more chunks to write, this event is emitted.

So, for example,

```
res.on('finish', callback);
res.redirect('/pageOne');
```
