# Highland Callback

Run callback after a stream is complete. This will run the callback once, on the first error or when the stream has
finished. Note that you should only use this as the last `.consume` in the stream chain.

## Install

    npm install highland-callback

## Usage

    var _ = require('highland');
    var highlandCallback = require('highland-callback');

    _([1, 2, 3])
    .consume(highlandCallback(function(error) {
      // executed after nil is seen, in this case all the values will be logged before this is executed
      console.log('executed');
      console.log('hi');
    }))
    .doto(function(value) {
      console.log(value);
    })
    .resume();

    // output:
    // 1
    // 2
    // 3
    // executed
