# callbag-pausable-interval

A callbag listenable source that sends incremental numbers every x milliseconds, but can be paused (and resumed) when it is pulled by a sink. 

This is a hybrid source, it is both listenable and pullable. Don't use `forEach` directly as the sink for this source, because `forEach` pulls every time it receives data. You can use this source as the argument for `sample`, though.

`npm install callbag-pausable-interval`

## example

```js

const pausableInterval = require('callbag-pausable-interval')

const source = pausableInterval(600)

source(0, (type, data) => {

  if (type === 0) {

    const talkback = data

    // Every 2 seconds, send a message "null" back to the source

    setInterval(() => talkback(1, null), 2000)

  }

  if (type === 1) console.log(data)

})

// 0

// 1

// 2

// ...pauses and waits...

// 3

// 4

// 5

// ...pauses and waits...

// 6

// 7

// 8

// ...

```
