Export to PDF

[Jakob Gillich]

Puppeteer has the ability to export a page to a PDF, and that feature was recently added to Firefox as well.

Is it possible to support this in Marionette? As far as I can tell, the WebDriver protocol does not support this feature.

If it's not a feature supported by webdriver that's a no. Puppeteer uses the DevTools protocol, which allows it to do a lot more than we can with webdriver. I wanted to wrap DevTools as well at first, but dealing with event based IO like WebSockets in Crystal is a pain right now.

Can you tell me more about that? I might actually build this.

So there's two libraries you might look at right now. I considered doing this again, but I've been working on other things. The first is playwright which is a newer project by Microsoft that's supposed to be "the new puppeteer". And there's puppeteer itself which is a Google project. I'd focus on replicating the functionality of playwright if I were you. Google also has decent API documentation for the Devtools Protocol.

Thank you, I will check it out. I think this can be closed.
