Support for running phantomas in SlimerJS #313

Closed macbre closed 10 years ago

macbre commented 10 years ago

PhantomJS 2.0 release is past due by about 1 month and there are quite a lot of bugs still open.

Consider porting phantomas to SlimerJS:

it has the latest JavaScript engine
supports all HTML5 standards (including Audio, Video and WebGL)
support for Flash
they claim to have API 98% compatible with PhantomJS
onResourceReceived passes the body of the response (yay!)

Disadvantages:

SlimerJS is not headless, but xvfb can be used on *nix boxes where xorg is not installed

@stefanjudis, @william-p, @cvan, @gomezd - let's discuss it :)

NPM package

gomezd commented 10 years ago

Could it be possible to abstract phantomas core so it runs on both? That opens more possibilities for testing in webkit and gecko browsers, similar to what casperjs is doing.

@gomezd, as far as skimmed through SlimerJS documentation, that's possible and definitely worth it.

Will command line options like the following be enough?

--engine [gecko|webkit]

alternatively:

--gecko
--webkit

stefanjudis commented 10 years ago

Including both sounds great! :+1:

Guys, thanks for your feedback. Issue title updated accordingly :)

cvan commented 10 years ago

For an old side project of mine, I've gotten SlimerJS working with xvfb on my local machine and a VPS. However, I did have issues using it on Stackato (ActiveState's PAAS like herkou) where the requested frame buffer memory size caused SlimerJS to crash on graphic-intensive web sites.

I think we should totally do this, but we should do thorough testing on pages of varying sizes.

macbre commented 10 years ago

@cvan, thanks for the feedback! It will definitely require lots of testing.

SlimerJS playground

macbre commented 10 years ago

Blockers:

[x] Please support require("system").stdin
[x] slimer.exit() should be able to set exit status
[x] provide paths to CommonJS modules installed via npm (require.paths)
[x] the lack of system.stderr slimerjs/#189
[x] init event triggered twice

TODOs:

[x] run via xvfb

macbre commented 10 years ago

SlimerJS support (run via xvfb) added to phantomas as an experimental feature. Core functionality works correctly, expect some glitches in various modules :)
