Vercel app for taking screenshots of web pages using Puppeteer

Original code by @styfle in this pull request.

I upgraded the code to work with the latest Vercel and added a ?key= mechanism to protect it from unauthorized access.

Usage

Set a Vercel secret called SECRET_KEY with a random string in it (I generated mine by running uuidgen | md5), then deploy.

You can access screenshots for pages using:

https:/.../zeit.co/blog?type=png&key=...

Screenshots can take several seconds to generate so it's a good idea to cache them somewhere.

Querystring arguments

• ?viewportWidth= sets the browser viewport width in pixels. This defaults to 800.
• ?viewportHeight= sets the browser viewport height in pixels. This defaults to 600.
• ?type= set the output type to png or jpeg. Default is png.
• ?quality=75 set the JPEG output qualit. Ignored for PNG.
• ?fullPage=true fetch a screenshot of the full page, not just the browser viewport.
