personal-puppeteer

This is a personal web page screenshotting service. By personal I mean only I can use it. But it is open source, and you can run your own instance.

How to use it

1. Generate a JWT with these fields:

   Key	Description
   iss	JWT issuer, which must be in the following allowlist
   url	URL to screenshot
   width	Width of the viewport
   width	Height of the viewport
   deviceScaleFactor	1 for normal display, 2 for retina
   waitUntil	load / domcontentloaded / networkidle0 / networkidle2
   js	Custom JavaScript code to run after page load
   css	Custom CSS to inject into page

2. Construct a URL and use it:

Notes

• The generated screenshot is then cached by Vercel Edge Network. The cache header being used is public, immutable, no-transform, s-maxage=31536000, max-age=31536000, which means that you must generate a new URL to invalidate the cache.
