I just got bitten by a variation of this too - I'm just using AMD with requirejs.
You cannot mix and match them. Put require.js, pubsub.js and this HTML file in the same directory:
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript" src="require.js"></script>
<script>
require(['pubsub'], function (PubSub) {
// PubSub in this scope (given as param from require) is not the
// same as window.PubSub, and maintain different sets of
// subscriptions, which is surprising
PubSub.subscribe(
'myEvent', function (name, value) {
console.log("required subscription", name, value);
}
);
window.PubSub.subscribe(
'myEvent', function (name, value) {
console.log("global subscription", name, value);
}
);
PubSub.publish('myEvent', 'required publish');
window.PubSub.publish('myEvent', 'global publish');
});
</script>
</head>
<body>
</body>
</html>
It prints this in the console:
requrired subscription myEvent required publish
global subscription myEvent global publish
I was definitely expecting four lines of input: Both subscriptions should be called for both publishes.
Or - at least - pubsub.js shouldn't set a global variable when being requiredd.
