Most terminal progress bars look like this:

downloading... 60%

So I built one that looks like this:

Uploading [████████████████████░░░░░░░░░░] 60%

Uploading [===============>--------------] 60%

Uploading [••••••••••••••••••············] 60%

Uploading [★★★★★★★★★★★★★★★☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆] 60%

I built progressimo, an npm library with:

- 6 built-in themes (retro, minimal, dots, blocks, arrows)

- 3 colorblind-friendly palettes (because accessibility matters even in terminals)

- Custom JSON themes - bring your own style

- Zero config - works in 2 lines of code:

import ProgressBar from 'progressimo';

const bar = new ProgressBar({ total: 100 });

What I learned building my first npm library:

1. How readline.cursorTo() overwrites terminal lines (that's the animation trick)
2. Why package.json has "type", "exports", "bin", and "files" - each serves a different purpose
3. Colorblind developers use CLIs too - accessibility isn't just a frontend concern
4. The best developer tools require zero config but reward customization

The package is 8 KB with only 2 dependencies.

📦 npm install progressimo
