bridge between node.js and PhantomJS using pure WebSockets
This is a port of the node-phantom library to use pure WebSockets. It has the following advantages over node-phantom:
cluster(node-phantom does not due to how
server.listen(0)works in cluster)
You will need to install PhantomJS first. The bridge assumes that the "phantomjs" binary is available in the PATH.
For running the tests you will need Expresso. The tests require PhantomJS 1.6 or newer to pass.
npm install node-phantom
You can use it exactly like you would use Node-Phantom, for example this is an adaptation of a web scraping example :
var phantom=require'node-phantom';phantomcreatereturn phcreatePagereturn pageopen""console.log"opened site? " status;pageincludeJs''//jQuery Loaded.//Wait for a bit for AJAX content to load on the page. Here, we are waiting 5 seconds.setTimeoutreturn pageevaluate//Get what you want from the page using jQuery. A good way is to populate an object with all the jQuery commands that you need and then return the object.var h2Arr =pArr = ;$'h2'eachh2Arrpush$thishtml;;$'p'eachpArrpush$thishtml;;returnh2: h2Arrp: pArr;console.logresult;phexit;;5000;;;;;
options is an optional object with options for how to start PhantomJS.
options.parameters is an array of parameters that will be passed to PhantomJS on the commandline.
will start phantom as:
You may also pass in a custom path if you need to select a specific instance of PhantomJS or it is not present in PATH environment. This can for example be used together with the PhantomJS package like so:
You can also have a look at the test folder to see some examples of using the API.
