ChromicPDF - PDF generator
Hello!
Came here to announce ChromicPDF, a pet project PDF generator I’ve been working on for the past few months. Why another PDF generator, you may be asking? Because it was fun to implement a client for (small parts of) the Chrome DevTools Protocol in Elixir.
That’s basically Chromic’s main feature, it can talk to Chrome without the need for puppeteer / a NodeJS at runtime. It launches Chrome, spawns a number of targets that it keeps around, and to print a PDF instructs them to navigate to a URL. In sum, this makes for relatively performant PDF generation flow.
For good measure, I threw in a PDF/A converter using Ghostscript, capable of creating veraPDF-test-passing PDF/A-3b files - obviously inspired by a project where we needed to generate invoice PDFs for long-term storage.
Would be super interested in any opinion you might have! It’s not (yet) on hex.pm, will wait a bit to see if people are interested. Documentation can be found in the README and, oddly, in the Supervisor module.
cheers,
Malte
Also kudos to my employer for letting us work on pet projects

There is for example PrawnPDF in Ruby GitHub - prawnpdf/prawn: Fast, Nimble PDF Writer for Ruby · GitHub and they do it without a browser or other libs. I always wondered why there is nothing like this in Elixir.

Have not read the code nor do I know about the Chrome api, but maybe those options will be passed directly to the API and he just wanted to avoid manually converting from snake case to camel case.
If that is the case, I personally would leave it as it is as it follows the API and people who are familiar with the API would have an easier time working with it. However, if the goal is to completely abstract that, then having them in snake case would be better.
It depends on the viewpoint.
