callback-collector

------------------

When I was first getting acquainted with node.js, I was experimenting with different

ideas for handling async callbacks. This is one of the ideas I had where you wrap each

of your callbacks in a call to `callback-collector`. `callback-collector` intercepts each

callback and counts the number of still pending callbacks.

Ultimately it is not what I settled on for general use; I do not recall exactly why. But,

here it is for good measure anyway.

install

-------

```bash

npm install callback-collector

```

example

-------

```js

var request = require('request');

var cbc = require('callback-collector');

var c = cbc(function () {

	console.log('0. all callbacks have been called');

});

setTimeout(c(function () {

	console.log('1. setTimeout is done');

}), 1000);

request('https://www.google.com', c(function (err, res, data) {

	console.log('2. https request is finished');

}));

```

output:

```bash

2. https request is finished

1. setTimeout is done

0. all callbacks have been called

```
