# callbag-tap

[Callbag](https://github.com/callbag/callbag) operator that allows you to `tap` data, error and completion. Allows you to inspect and do side effects without disturbing the stream.

In contrast to [forEach](https://github.com/staltz/callbag-for-each) which is a sink and actively consumes sources), `tap` does not consume sources.

Install with:

`npm install callbag-tap`

You can tap data, error and completion respectively:

```js

const tapped = tap(dataTapFunc, errorTapFunc, completionTapFunc)(source);

```

## example

```js

const fromIter = require('callbag-from-iter');

const tap = require('callbag-tap');

const forEach = require('callbag-for-each');

const source = fromIter([1,2,3]);

const tapped = tap(x => console.log("tap", x))(source);

const sink = forEach(x => console.log("sink", x))(tapped);

// tap 1

// sink 1

// tap 2

// sink 2

// tap 3

// sink 3

```
