Install

run npm install. This installs one dependecy:

• phantom: https://www.npmjs.com/package/phantom

Test

To run the tests execute npm test. Please install the dev dependencies first.

When to use this

Please note that executing the browserNetworking.request function is insanely slow compared to normal HTTP networking (which is slow already). This package should only be used if speed is not an issue.

Example implementations:

• Check wether or not a certain website includes your banner or copyright image
• Check if certain scripts make certain calls as expected (for testing maybe, but there are better ways to achieve that)

It is recommended to run the script from a queue or cronjob in seperate non-blocking calls. The process is CPU intensive. This is what happens:

• The request function is called with an URL
• PhantomJS is started. PhantomJS is a headless browser (no GUI).
• We navigate to the given URL
• We wait for the page to completely load and catch all called URLs
• We return the result and close the workers in the background

API

Exposes a request function which takes one argument: the url of the request. The function returns a Promise. The promises resolves to an Array of urls or rejects to an error object.

Example

browserNetworking.request('http://www.google.com').then(urls => {

        // urls is an array of resources requested by the browser

    },
    error => {

        // handle error

    });

The result for Google (depending on your geolocation, the IP, etc) would look something like this:

[ 'http://www.google.com/',
