This project provides a NodeJS interface for interacting with a running BrowserMob Proxy through it's REST API. All methods in the REST API are available including JavaScript-based interceptors for requests/responses.

Installation command is npm install browsermob-proxy-api

For the specifics of the REST API used by BrowserMob Proxy, please see their documentation.

To open a port (10800) and start a new HAR:

var MobProxy = require('browsermob-proxy-api');
var proxy = new MobProxy({'host':'localhost', 'port': '8080'});

// start listening on port 10800:
proxy.startPort(10800, function(err, data) {
    // start new HAR report
    proxy.createHAR(10800, { 'initialPageRef': 'foo' });
});

To get the current HAR from a previously opened port:

proxy.getHAR(10800, function(err, data) {
    console.log(data);
});
