Typesetter's Son

Typesetter's Son is a small utility for generating images and PDFs based on lightly modified webpages. It loads a URL in Headless Chrome, substitutes innerHTML for elements you specify, and takes a screenshot.

It works great on SVGs too -- just sprinkle in id attributes where you want to modify text!

Installation

Library: npm install typesetters-son
Executable: npm install -g typesetters-son

typesetters-son http://dogpatchjs.com/banner -o dogpatch.png -w 1024 -c 'body' -s '{"#day": "Monday, July 17, 2017", "#where": "Spark Social", "#time": "6:30pm"}'
