I think before landing this we should try to address the question at #468 (comment).

@annevk Thanks for making this link. I think we should work out an answer in conjunction with TC39 to this question, given that ECMAScript includes things that are pretty equivalent in power/appropriateness to put everywhere to TextEncoder and URL. I'm fine with letting this PR be blocked on this question.

We should include the jsidl label on this issue, since all ES APIs will need to be exposed to all globals

@littledan I believe we should follow up on this PR for the proper ShadowRealms integration, right?

We could add this for ShadowRealms, or we could just add [Exposed=ShadowRealm]. The choice depends on whether we want to go around adding lots of things to Worklets which are not currently exposed, and which we might decide to expose on ShadowRealm. In offline conversations with different HTML editors, I heard mixed opinions on this question, cc @domenic @annevk . Given that, I thought that it might be better to start with the more conservative approach of just adding things specifically to ShadowRealm.

I think it'd be better to add [Exposed=*]? Saying that in worklets you have to access these APIs indirectly via shadow realms seems strange.

annevk commented Sep 23, 2021

In an offline discussion tc39/ecma262#1120 came up, but since we did not change JavaScript to support minimal realms (i.e., a subset of what is defined in JavaScript), we should not do so here by excluding worklets. (As that would make worklets the new minimal realms due to organizational boundaries.)

As I understand it the primary motivation for having minimal realms in worklets was to avoid steering web developers down the wrong path, but in practice this hasn't been much of a problem.

This is a long way of saying that I agree with @domenic, but I thought it might be useful to add some context.

OK, thanks for the clarifications everyone, sounds like I was the confused/misunderstanding one. Does that mean we should move ahead with [Exposed=*]?

@Ms2ger it would be helpful if you could make a list of interfaces which [Exposed=*] is proposed somewhere publicly. Thanks!

Besides the ones already listed in tc39/proposal-shadowrealm#331, we might propose some parts of Crypto and Performance - please do let me know if you'd like me to present the list in some other way

This change looks great, but I don't think it handles the ShadowRealm case yet, since that is not an interface.

@littledan that's a good point. I suppose we should put that requirement in HTML along with the overall ShadowRealm integration?
