Custom module loaders and script tags

# Guy Bedford (12 years ago)

I'm trying to work out how custom module loaders can be used with standard script tags.

For example, say I create a RequireJS-style loader (with an identical configuration API including map config etc), and want to use this within a script file loaded via a script tag:

<script>
  var RequireJSStyleLoader = new Loader({
    // ... etc ...
  });
</script>
<script src="some/module/file.js"></script>

How do I configure the loader to know that "some/module/file.js" should have its imports and module declarations applied with my custom loader (RequireJSStyleLoader) and not the system loader?

Or is it only possible to set a custom loader for imports executed with RequireJSStyleLoader.load(...)?

Currently, that's all that's possible. Dave and I plan to talk to people on the HTML side to enable this as well, but that has not yet begun.

Would it be better simply to override the default system loader, or would this be discouraged?

I notice Yehuda's examples are based on overloading of the System loader, so perhaps this will be the standard method.

We expect that modifying the System loader will be common, and creating new Loaders will be reserved for when new isolated context are required.

Ok sure, good to know, that makes a lot more sense. That covers my other post as well then. Reading the specs, it seemed like "new Loader" was the common form, and the idea of modifying a system global sounds like something generally to avoid, but here it does seem like it will be the better option in many cases.
