Use Rollbar (https://rollbar.com/) with Browserify

rollbar.js

// Download rollbar.js and rollbar.min.js from:
// http://d37gvrvc0wt4s1.cloudfront.net/js/1/rollbar.js
// http://d37gvrvc0wt4s1.cloudfront.net/js/1/rollbar.min.js
//
// Place them into vendor/ and this code into lib/rollbar.js, or something

(function(w, d) {
  w._rollbarParams = {
    "server.environment": "production",
    "notifier.snippet_version": "2"
  };

  w._rollbar = ["PASTE_CLIENT_ACCESS_TOKEN_HERE_PLEASE", w._rollbarParams];
  w._ratchet = _rollbar;

  // Catch all exceptions and errors
  w.onerror = function(e, u, l) {
    _rollbar.push({
      _t: 'uncaught',
      e: e,
      u: u,
      l: l
    });
  };
})(window, document);

require('../vendor/rollbar');

This little "hack" gets Rollbar working with Browserify, and with no extra requests! :) The client-side Rollbar script is bundled in with your own code. You just have to periodically check for new Rollbar version and update it in your Browserify project.
