asciinema is a terminal screen recorder.
📦 Node.js, 🌐 Web, 📜 Files, 📰 Docs. 📘 Wiki.

With this package you can auto-generate terminal recordings for Node.js examples through asciinema programmatically. But you need to install asciinema first!

This package is available in Node.js and Web formats (for retimeData()). The web format is exposed as extra_asciinema standalone variable and can be loaded from jsDelivr CDN.

Stability: Experimental.

const asciinema = require('extra-asciinema');
// import * as asciinema from 'extra-asciinema';

asciinema.recSync('saved.cast', {input: 'example.js'});
// runs example.js interactively in node.js, saves 'saved.cast'

asciinema.retimeSync('saved.cast', {inputDelay: 2});
// 'saved.cast' is updated

asciinema.uploadSync('saved.cast');
// asciicast URL
