Dockerized web api to convert HTML to PDF using phantomjs

Html to PDF API

Exposes an API to convert Html to PDF.

It is just a small API (using express) over the phantom-html-to-pdf NodeJS package, so any options for phantom-html-to-pdf can be passed.

Routes

• GET /test - Internal test to make sure PDF creation is functioning properly. It will return a pair of 2x1 labels.
• GET /test.html - Returns the HTML used to create the two labels.
• GET /test.json - Returns the json passed to the self-test.
• POST / - Receives a json body with the options to be passed into PDF converter. Returns PDFs.

Notes

For some reason, with PhantomJS 2+ the zoom is off when rendering to PDF. I offset this in my POC by setting a zoom factor when rendering the page, but with the phantom-html-to-pdf package I didn't have a good way to do this. I solved it by duplicating the entire phantomjs rendering script from his repo, adding the little stub I needed, and then passing the new script file path into the converter engine.
