Description

This PR changes the way opaque data is stored in eszip and makes allow lazy-load for individual data stored in eszip.

console.log(typeof createClient);
Deno.serve((_req) => new Response("Hello, world"));

Notes

It supports runtime migration for bundles created before this PR. However, performance will revert back to what it was before, so I recommend regenerating the bundle.

Once this PR is merged, it is worth looking closely to ensure that it is completely compatible with the previous implementation.

why removing this function? We could just create an async one?

[nyannyacha]

I recall that some of the functions it calls in its function body had their signatures changed to async, so I changed those functions to async due to contagious.

[nyannyacha]

I guess I could probably make that synchronously again by spawning async functions in the blocking threads

LGTM! Did some testing locally and common scenarios seems to work :)
