What can you do with SlimerJS?
SlimerJS allows you to execute JavaScript outside a classical web browser.
In your JavaScript you can use modules, providing access to many APIs:
Your script is also able to execute CommonJS modules,
even those written with the CoffeeScript language!
Your main script can be written with CoffeeScript as well. SlimerJS recognizes *.coffee
files.
In your Slimerjs scripts, benefit latest Javascript features implemented in Firefox, including ECMAScript 6 features: iterators, generators, destructured assignement, Map and WeakMap, "let" keyword, arrow functions, promises etc.
Since SlimerJS is executed on top of Firefox, it supports all the HTML5 standards recently implemented in Firefox, including things like audio, video, WebGL etc.
In fact, SlimerJS is not really stuck to a specific version of Gecko: it can use any recent version of Firefox 38+.
The web page rendering in SlimerJS is strictly identical to the rendering in Firefox.
No problem to launch your web site or your web app that use HTML5 bleeding edge features!
See the download page to know the version of Firefox compatible with the latest release of SlimerJS.
You can go on caniuse.com to see the list of HTML5 features supported by Firefox and you can use in web pages loaded by SlimerJS.

APIs of SlimerJS are similar to the APIs of PhantomJS but there are a few differences in their behavior. Some options and a few features are still missing. We're working on it. Feel free to help us to have a full compatibility (see release notes to have the list of missing features).
However, most of scripts for PhantomJS run perfectly well right now with SlimerJS!
Contrary to PhantomJS, SlimerJS is not headless: you see windows
and it needs a graphical environment. You can use a tool like
xvfb
on a Linux/MacOS system to have this headless
feature and to execute SlimerJS on Linux boxes that do not have xorg
installed.
