puppeteer-render-text-cli

CLI for rendering text with headless chrome.

This CLI is also available as a library.

Why?

ImageMagick is the traditional unix tool to programatically render text, and while it works very well for simple use cases, trying to use it to render rich text or html is very difficult. Pango is another option that's been around for ages, but both suffer from archaic syntax and minimal rich text support.

Puppeteer, on the other hand, allows for robust, headless chrome screenshots with best-in-class support for all modern html / text / font features.

This CLI makes it easy to use headless chrome to render text + html to images.
