@articulate/progress

Cheap, functional, terminal progress bar.

Next time you're tempted to process.stderr.write('.') to track the progress of a script... don't. Use this instead.

API

progress : Object -> Number -> ()

To setup your progress bar, execute the module with an optional options object:

const progress = require('@articulate/progress')({ /* options here */ })

The following options are accepted:

Name	Type	Default	Description
label	String	'progress'	custom label for your progress bar
stream	stream.Writable	process.stderr	output stream for progress
width	Number	24	max width of the bar

The returned function accepts a progress ratio between 0 and 1, and writes the progress bar to the output stream. Each time it is called, it will overwrite the previous state of the progress to appear animated in the console.

const progress = require('@articulate/progress')()

progress(0.55)
//> progress: ⣠ [==============          ] 55%

See demo.js for a slightly more complex example.
