Added an explicit type to all $FlowFixMe suppressions to reduce
over-suppressions of new errors that might be caused on the same lines.
Also removes suppressions that aren't used (e.g. in a `@noflow` file as
they're purely misleading)
Test Plan:
yarn flow-ci
We rely heavily on being able to batch rendering after multiple fetches
etc. have completed on the server. However, we only do this in the
Node.js build. Node.js `setImmediate` has the exact semantics we need.
To be after the current cycle of I/O so that we can collect after all
those I/O events already in the queue has been processed.
This doesn't exist in standard browsers, so we ended up not using it
there. We could've used `setTimeout` but that risks being throttled
which would severely negatively affect the performance so we just did it
synchronously there. We probably could just use the `scheduler` there.
Now we have a separate build for Edge where `setTimeout(..., 0)`
actually behaves like `setImmediate` which is what we want. So we can
just use that in that build.
@Jarred-Sumner not sure what you want for Bun.
We currently abuse the browser builds for Web streams derived
environments. We already have a special build for Bun but we should also
have one for [other "edge"
runtimes](https://runtime-keys.proposal.wintercg.org/) so that we can
maximally take advantage of the APIs that exist on each platform.
In practice, we currently check for a global property called
`AsyncLocalStorage` in the server browser builds which we shouldn't
really do since browsers likely won't ever have it. Additionally, this
should probably move to an import which we can't add to actual browser
builds where that will be an invalid import. So it has to be a separate
build. That's not done yet in this PR but Vercel will follow
Cloudflare's lead here.
The `deno` key still points to the browser build since there's no
AsyncLocalStorage there but it could use this same or a custom build if
support is added.
