Custom error handling

[tomyam1]

I would like to integrate my custom error handling to karma-browserify, e.g. notify with node-notifier when there is a bundling error.

Currently karma-browserify just logs errors to the console and it takes me some time to realize that an error has occurred. Especially when tests are run due to a change of a watched file.

I couldn't find any API for that, but this monkey-patch seems to work fine:

// monkey patch karma-browserify before karma starts
var KarmaBrowserify = require('karma-browserify');

KarmaBrowserify['framework:browserify'][1] = function framework(injector, bro) {
  var w = injector.invoke(bro.framework);
  w.on('bundled', function(err, content) {
    if (err) {
      // Custom error handler
    }
  });
  return w;
};

Is there any correct way to do that? If not, would you consider adding such mechanism?

No great answer here. An error event will crash the process unless we only emit if there's a listener. There's already some non-standard events so I think it's reasonable. Will take a PR.

I see. For now I'll stay with my current solution. Thanks for the quick response @bendrucker !
