PhantomJS: Conceptual implementation of a short-term shim to establish the window.postMessage API for IPC

Topic

Providing an inter-process communication (IPC) mechanism such that a WebPage can explicitly signal back to PhantomJS as a push, thus eliminating/minimizing the need for users to setup polling functions, etc.

In PhantomJS 1.6, @detro added a WebPage onCallback handler that could be triggered from a webpage client by invoking the specially attached window.callPhantom function. However, @ariya expressed some discontent with this approach and so the three of us began discussing utilizing an existing API for cross-domain messaging instead: window.postMessage. (See Discussion for more info.)

Problems

PhantomJS currently only allows for a single handler per signal (a separate problem I'm working on over here). As such, automatically attaching internal handler may prevent users from attaching their own handlers for onInitialized (tha

I like phantomjs, but it doesn't directly support getting images from webpages without requesting them separately like in casperjs. I went through QTNetworking code in the phantomjs repo until I figured out where the cache was. To use this, have all three files in the same directory. Then modify test.js for whatever you need. Call phantom js wit…
var fs = require('fs');
//this is the path that QTNetwork classes uses for caching files for it's http client
//the path should be the one that has 16 folders labeled 0,1,2,3,...,F
exports.cachePath = '/path/to/phantomjs/cache/data/folder';
//this is the extension used for files in the cache path
exports.cacheExtension = "d";
//the resources that are to be saved
