A progress bar NodeJS

Example

var KeyLoad = require('keyload')

var bar = new KeyLoad({
  whole: 20, // Total amount for loading bar
  undone: ' ', // Character for the undone section of the loading bar
  done: '=', // Character to be used for the finished sectiond of the loading bar
  middle: '>', // The middle character on the loading bar
  stream: process.stderr // The stream for output
})

// Interval for ticking up the bar
var interval = setInterval(bar.tick, 500)

// Interval for setting a random message on the bar
var interval2 = setInterval(function() {
  bar.message('f'.repeat(Math.round(Math.random() * 100) % 16))
}, 500)

// Listener for the bar being finished
bar.on('end', function() {
  clearInterval(interval)
  clearInterval(interval2)
  console.log('complete')
})

// Increasing the bar by one
bar.tick()

API

tick()

Increases the bar by one.

on(eventStr, callback)

Listen for events on the bar. Currently only end is supported.

message(string)

Put a message on the loader bar. It will be truncated or removed if there is not enough space. This is the alternative to console.log while using this bar, since it unfortunately breaks it.
