Duration set to 0 not work

[abchjsabc]

In line 21
args.duration = args.duration ? args.duration : defaultDuration;
If duration is set to 0, args.duration equals defaultDuration and it violates the doc

duration - Optional. The duration (in milliseconds) of message. A duration of 0 will prevent messages from closing automatically.

Workaround - set duration to any non-empty string. Since 'string' > 0 === false, but 'string' is truthy, it will prevent the timeout code from being triggered.

This is by no means a good solution, but it's a workable temporary workaround.

If you want to take it one step further, you could patch this for your local project globally with the following interceptor (test before using! :) ):

angular.module('myApp').config(function ($provide) {
    $provide.decorator('notify', function ($delegate) {
      return function (args) {
        if (typeof args !== 'object') {
          return $delegate(args);
        }

        if (args.duration === 0) {
          // Workaround
          args.duration = 'never close';
        }

        return $delegate(args);
      }
    });
  });

This will prevent things like notify.closeAll() from working, so beware!
