Qwik City on Fastly

[kalebpace]

Summary

Hello 👋

I've been working on an adapter for the Qwik City meta-framework so it can be run on Compute@Edge. I wanted to open this issue to ask a few questions and socialize this work a bit in case this is helpful to anyone else.

I've run into a few missing APIs in the js-compute runtime when implementing the adapter in Qwik City's e2e integration project:

• AbortSignal API
• formData/blob on Request objects
• Intl API - Causes wizer error

Wizer Error

Exception while evaluating JS: (new ReferenceError("Intl is not defined", "<stdin>", 20115))
  @<stdin>:20115:12
  @<stdin>:25647:3

Error: the `wizer.initialize` function trapped

Caused by:
    0: error while executing at wasm backtrace:

Questions

I am mainly curious about:

1. Whether these APIs are planned for the runtime
2. How a project like https://github.com/fastly/next-compute-js might suggest solving for their unavailability

Thanks very much in advance for your time and attention to this!

Hi @kalebpace,

Whether these APIs are planned for the runtime

Yes, we would like to implement these APIs

How a project like fastly/next-compute-js might suggest solving for their unavailability

I'm not sure on that one, I don't work on the next-compute-js project, if you open an issue on that project then hopefully the team their will be able to answer 🤞

Hey @JakeChampion, thanks for looking at this.

Yes, we would like to implement these APIs

Since there is interest here, is there a recommendation on how best to contribute/start work on these changes?

For example, the missing Intl API seems to be a flag in the spidermonkey runtime.

Would it be as simple as opening a PR with a successful build of it enabled or are there larger implications to making a change like this?
