Release notes

SlimerJS allows you to interact with a web page through an external JS script

> Opening a webpage,
> Clicking on links,
> Modifying the content...

SlimerJS is useful to do functional tests, page automation, network monitoring, screen capture, etc.

SlimerJS is similar to PhantomJs, except that it runs Gecko, the browser engine of Mozilla Firefox, instead of Webkit (And it is not yet truly headless).

Simple example
var webpage = require('webpage').create();
webpage
  .open('http://somewhere') // loads a page
  .then(function(){ // executed after loading
    // store a screenshot of the page
    webpage.viewportSize =
        { width:650, height:320 };
    webpage.render('page.png',
                   {onlyViewport:true});
    // then open a second page
    return webpage.open('http://somewhere2');
  })
  .then(function(){
    // click somewhere on the second page
    webpage.sendEvent("click", 5, 5,
                        'left', 0);
    slimer.exit()
  });
