One thing we’ve been meaning to do more of is tell our blog readers more about new features we’ve been working on across WHATWG standards. We have quite a backlog of exciting things that have happened, and I’ve been nominated to start off by telling you the story of
charset attributes applied. The end result can be seen in a number of places in the HTML Standard, most notably in the definition of the
script element and the scripting processing model sections. At the request of the Edge team, we also added support for worker modules, which you can see in the section on creating workers. (This soon made it over to the service workers spec as well!) To wrap things up, we included some examples: a couple for
<script type="module">, and one for module workers.
Of course, specifying a feature is not the end; it also needs to be implemented! Right now there is active implementation work happening in all four major rendering engines, which (for the open source engines) you can follow in these bugs:
And there's more work to do on the spec side, too! There's ongoing discussion of how to add more advanced dynamic module-loading APIs, from something simple like a promise-returning
self.importModule, all the way up to the experimental ideas being prototyped in the whatwg/loader repository.
