Excellent! I have used PhantomJS for web scraping but as that is always a gray area of legality. I'd love to hear any other major uses you've seen it used for. I always love it when I find that a tool I'm using can be used for other purposes.

I use it to print out HTML presentations. I did found some very annoying bugs in saving to PDF (I'll have to see if they have got fixed!), but this is the only (scriptable) way I know of saving each slide of a HTML presentation to PDF (which you need sometimes)

I used PhantomJS to drive a system integration with a hostile legacy web application.

By hostile I mean that the legacy system had no API, was implemented using obfuscated code, and resisted being driven by URLs.

We needed to integrate with it to create documents, calendar appointments, etc. in the legacy system, based on stuff that was happening in the newer system we were building.

We ended up using PhantomJS to implement a module that drove the legacy system via its HTML user interface -- pushing buttons, selecting meeting participants from the HTML select tags, submitting forms, etc.

Although that sounds (and is!) hacky as hell, it worked flawlessly 100% of the time. PhantomJS was a gift from the gods.

Primarily scraping of comet/ajax updating sites of course, but also some interesting uses for testing - crawling a site taking screenshots and then comparing screenshots across releases looking for layout bugs was quite a fun thing. The same principle as https://github.com/BBC-News/wraith

I once wanted to do automated testing with it. But because PhantomJS used an old webkit version, I couldn't :(

But that's one use case where I would love to use phantomJS or any other headless engine to test the frontend. I'm aware that for headless testing to work, there should be a headless browser of every major vendor. Maybe it's an utopia.

I've been using jquerygo (which runs on phantomjs) to do automated UI testing. The familiar jquery selectors are convenient!

Being able to use websockets in my automated testing has been something of a holy grail, so jquerygo and phantomjs have been hugely helpful.

Yes, my team ran directly into the old webkit version issue as well. Does this 2.0 still use an old WebKit? Having trouble finding out...

Edit: it appears to be WebKit 538.1, from May 2014. But this is based on a readme which is pretty old, so it could be outdated info

[pothibo]

It uses a new version of Webkit(That includes DOM Mutation Events IIRC). But I believe that they always ship with their own version of webkit, which will always be behind.

For PhantomJS 2.0, I think they ship with a version of webkit that is > 6 months old.

[warfangle]

They don't ship with their own version of webkit; they use qtwebkit (or at least used to?).

I have solved this problem by using SlimerJS as an alternative.

[serve_yay]

Yeah, unfortunately we can't install that one on our build box, I believe because it needs X11. (As the page says it is not "totally headless")

[simlevesque]

You are mistaken. You can install SlimerJS on a box without X11. You must install Xvfb use it like this : xvfb-run slimerjs script.js

If you use casperjs you can modify the executable (it's python) and change "'default_exec' : 'slimerjs'" into "'default_exec' : 'xvfb-run slimerjs'"

I use it to let my linux-based custom digital picture frame automatically pull photos from my IOS photostream. This is insecure because it requires that my photos are temporarily public, but it gets the job done.

Baking SVGs into PNGs for attaching to e-mails. We used D3 to generate SVG charts for displaying analytics data in-browser and then use Phantom to generate PNG versions. Works well.

We use it to generate screenshots to use as the images in our open graph tags.
