What?

This completes Turbopack's Server Actions implementation!

It also cleans up several things:

  • Removes server_actions configuration, it's enabled by default now.
  • Fixes the transform that runs in the SSR layer (it actually needs to use the client transform)
  • Generates a new encryption key

Why?

How?

It crawls the client layer modules for additional Server Actions imports, and adds them to our generated actions.js entry point.

Closes NEXT-
Fixes #

Closes WEB-1854

Should we rename that?

Why isn't that just 2 arguments

This is invoked by NonDeterministic::visit's fn impl, which only accepts a single arg.
