progress is a little package that draws a progress bar when iterating over an array in Node. It's kind of like tqdm.

Install it:

npm install --save https://github.com/jrc03c/progress

Use it:

const progress = require("progress")
const x = [5, 4, 3, 2, 1]

progress(x).forEach(value => {
  // do something with `value`;
  // while that's happening,
  // you should see a progress
  // bar at the bottom of the
  // terminal!
})

You can also set the progress bar value manually by passing either a fraction from 0 to 1 or a numerator and denominator:

progress(0.5) // 50%
progress(30, 60) // 50%
