What this PR solves / how to test:

This PR does two things:

  1. Renames the --node-compat CLI/config option internally to legacyNodeCompat. Nothing changes externally. You still invoke it with --node-compat or node_compat. We maybe want to think about moving this to experimental as we stabilize thedev() API, but that discussion can happen elsewhere.
  2. Marks any imports prefixed with node: as external when bundling with the nodejs_compat compatibility flag.

We need to add support for this compatibility flag in Miniflare (cloudflare/miniflare#473) but once the workerd PR is merged and released, this'll be available with --experimental-local.

Could we get tests for preventing users from running the legacy flag and the runtime flag together?

There are checks for exclusivitity throughout?

Correct, I would like to see tests for that as a proof/coverage of that check functionality.

Edit: I apologize, my wording was ambiguous.

What is the status of this PR?
Will it enable the use of async_hooks in worker scripts?

Currently I get this error when trying to use it:
The package "async_hooks" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

Is this PR related / will enable this workerd PR: cloudflare/workerd#208 ?

@danbars , still a work-in-progress! Please bear with us.

Hi @GregBrimble, sorry for nagging, I simply have a module that is pending on this PR - using async_hooks from node.
I'll be happy to know what is the expected timeline for this.
If this is a few weeks I guess I'll wait. Otherwise I'll probably develop an alternative solution that does not have this dependency.

Looks great. I like the "conjunction" messaging and I appreciate the tests around trying to use them together.
