# callbag-from

Convert a Promise, Event, Observable, or Iterable to a callbag listenable source. This simply wraps existing conversion utilities and autodetects which one to use.

`npm install callbag-from`

## examples

Convert an Event (https://github.com/staltz/callbag-from-event)

```js

const fromAny = require('callbag-from');

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

const source = fromAny(document.body, 'click');

observe(x => console.log(x))(source); // MouseEvent ...

                                      // MouseEvent ...

```

Convert a Promise (https://github.com/staltz/callbag-from-promise)

```js

const fromAny = require('callbag-from');

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

const source = fromAny(

  fetch('http://jsonplaceholder.typicode.com/users/1')

    .then(res => res.json())

);

observe(user => console.log(user.name))(source); // Leanne Graham

```

Convert an Observable (https://github.com/staltz/callbag-from-obs)

```js

const Rx = require('rxjs');

const fromAny = require('callbag-from');

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

const source = fromAny(Rx.Observable.interval(1000).take(4));

observe(x => console.log(x))(source); // 0

                                      // 1

                                      // 2

                                      // 3

```

Convert an Iterable (https://github.com/staltz/callbag-from-iter)

```js

const fromAny = require('callbag-from');

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

const source = fromAny([10, 20, 30, 40]);

source(0, iterate(x => console.log(x)); // 10

                                        // 20

                                        // 30

                                        // 40

```
