- Remove `NativeModule._source` - the compilation is now entirely
done in C++ and `process.binding('natives')` is implemented
directly in the binding loader so there is no need to store
additional source code strings.
- Instead of using an object as `NativeModule._cached` and insert
into it after compilation of each native module, simply prebuild
a JS map filled with all the native modules and infer the
state of compilation through `mod.loading`/`mod.loaded`.
- Rename `NativeModule.nonInternalExists` to
`NativeModule.canBeRequiredByUsers` and precompute that
property for all the native modules during bootstrap instead
of branching in every require call during runtime.
- Rename `NativeModule.requireForDeps` to
`NativeModule.requireWithFallbackInDeps`.
- Add a test to make sure we do not accidentally leak any module
to the global namespace.

@joyeecheung Can you look into backporting this to v11.x-staging? |
|
Seems like this requires a closer look. |
|
This should be backported along #25481. |
