# callbag-trace

[Callbag](https://github.com/callbag/callbag) operator for debugging that allows you to pass in a function (e.g. console.log) that will be called on each value as it is passed through.

`yarn --dev add callbag-trace`

## example

```js

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

const {forEach, fromEvent, map, filter, pipe} = require('callbag-basics');

const accum = []

pipe(

  fromEvent(document, 'click'),

  filter(ev => ev.target.tagName === 'BUTTON'),

  trace(console.log),

  map(ev => ev.target.id),

  forEach(id => accum.push(id))

)

```
