Update all our local scripts to use `build` instead of `build2`.
There are still downstream scripts that depend on `build2`, though, so
we can't remove it yet.
Uses the layout of the build artifact directory to infer the format
of a given file, and which lint rules to apply.
This has the effect of decoupling the lint build job from the existing
Rollup script, so that if we ever add additional post-processing, or
if we replace Rollup, it will still work.
But the immediate motivation is to replace the separate "stable" and
"experimental" lint-build jobs with a single combined job.
This allows exporting ESM modules for the Webpack plugin. This is necessary
for making a resolver plugin. We could probably make the whole plugin
use ESM instead of CJS ES2015.
* Lint bundles using the bundle config instead of scanning for files
This ensures that we look for all the files that we expect to see there.
If something doesn't get built we wouldn't detect it.
However, this doesn't find files that aren't part of our builds such as
indirection files in the root. This will need to change with ESM anyway
since indirection files doesn't work. Everything should be built anyway.
This ensures that we can use the bundles.js config to determine special
cases instead of relying on file system conventions.
* Run lint with flag
This commit is a follow-up to https://github.com/facebook/react/pull/15604, which explains more of the rationale behind moving React Native to path-based imports and the work needed in the React repository. In that linked PR, the generated renderers were updated but not the shims; this commit updates the shims.
The problem is that FB needs a different copy of the built renderers than the OSS versions so we need a way for FB code to import different modules than in OSS. This was previously done with Haste, but with the removal of Haste from RN, we need another mechanism. Talking with cpojer, we are using a `.fb.js` extension that Metro can be configured to prioritize over `.js`.
This commit generates FB's renderers with the `.fb.js` extension and OSS renderers with just `.js`. This way, FB can internally configure Metro to use the `.fb.js` implementations and OSS will use the `.js` ones, letting us swap out which implementation gets bundled.
Test Plan: Generated the renderers and shims with `yarn build` and then verified that the generated shims don't contain any Haste-style imports. Copied the renderers and shims into RN manually and launched the RNTester app to verify it loads end-to-end. Added `.fb.js` to the extensions in `metro.config.js` and verified that the FB-specific bundles loaded.
* Added new "native-fb" and "native-fabric-fb" bundles.
* Split RN_DEV and RN_PROD bundle types into RN_OSS_DEV, RN_OSS_PROD, RN_FB_DEV, and RN_FB_PROD. (This is a bit redundant but it seemed the least intrusive way of supporting a forked feature flags file for these bundles.)
* Renamed FB_DEV and FB_PROD bundle types to be more explicitly for www (FB_WWW_DEV and FB_WWW_PROD)
* Removed Haste @providesModule headers from the RB-specific RN renderer bundles to avoid a duplicate name conflicts.
* Remove dynamic values from OSS RN feature flags. (Leave them in FB RN feature flags.)
* Updated the sync script(s) to account for new renderer type.
* Move ReactFeatureFlags.js shim to FB bundle only (since OSS bundle no longer needs dynamic values).
* Move build/packages/* to build/node_modules/*
This fixes Node resolution in that folder and lets us require() packages in it in Node shell for manual testing.
* Link fixtures to packages/node_modules
This updates the location and also uses link: instead of file: to avoid Yarn caching the folder contents.
