Andrew Clark	857ee8cdf9	Don't minify symbols in production builds (#28881 ) This disables symbol renaming in production builds. The original variable and function names are preserved. All other forms of compression applied by Closure (dead code elimination, inlining, etc) are unchanged — the final program is identical to what we were producing before, just in a more readable form. The motivation is to make it easier to debug React issues that only occur in production — the same reason we decided to start shipping sourcemaps in #28827 and #28827. However, because most apps run their own minification step on their npm dependencies, it's not necessary for us to minify the symbols before publishing — it'll be handled the app, if desired. This is the same strategy Meta has used to ship React for years. The React build itself has unminified symbols, but they get minified as part of Meta's regular build pipeline. Even if an app does not minify their npm dependencies, gzip covers most of the cost of symbol renaming anyway. This saves us from having to ship sourcemaps, which means even apps that don't have sourcemaps configured will be able to debug the React build as easily as they would any other npm dependency.	2024-04-20 11:23:46 -04:00

Don't minify symbols in production builds (#28881 )

This disables symbol renaming in production builds. The original
variable and function names are preserved. All other forms of
compression applied by Closure (dead code elimination, inlining, etc)
are unchanged — the final program is identical to what we were producing
before, just in a more readable form.

The motivation is to make it easier to debug React issues that only
occur in production — the same reason we decided to start shipping
sourcemaps in #28827 and #28827.

However, because most apps run their own minification step on their npm
dependencies, it's not necessary for us to minify the symbols before
publishing — it'll be handled the app, if desired.

This is the same strategy Meta has used to ship React for years. The
React build itself has unminified symbols, but they get minified as part
of Meta's regular build pipeline.

Even if an app does not minify their npm dependencies, gzip covers most
of the cost of symbol renaming anyway.

This saves us from having to ship sourcemaps, which means even apps that
don't have sourcemaps configured will be able to debug the React build
as easily as they would any other npm dependency.

Run 90% of tests on compiled bundles (both development and production) (#11633 )

* Extract Jest config into a separate file

* Refactor Jest scripts directory structure

Introduces a more consistent naming scheme.

* Add yarn test-bundles and yarn test-prod-bundles

Only files ending with -test.public.js are opted in (so far we don't have any).

* Fix error decoding for production bundles

GCC seems to remove `new` from `new Error()` which broke our proxy.

* Build production version of react-noop-renderer

This lets us test more bundles.

* Switch to blacklist (exclude .private.js tests)

* Rename tests that are currently broken against bundles to *-test.internal.js

Some of these are using private APIs. Some have other issues.

* Add bundle tests to CI

* Split private and public ReactJSXElementValidator tests

* Remove internal deps from ReactServerRendering-test and make it public

* Only run tests directly in __tests__

This lets us share code between test files by placing them in __tests__/utils.

* Remove ExecutionEnvironment dependency from DOMServerIntegrationTest

It's not necessary since Stack.

* Split up ReactDOMServerIntegration into test suite and utilities

This enables us to further split it down. Good both for parallelization and extracting public parts.

* Split Fragment tests from other DOMServerIntegration tests

This enables them to opt other DOMServerIntegration tests into bundle testing.

* Split ReactDOMServerIntegration into different test files

It was way too slow to run all these in sequence.

* Don't reset the cache twice in DOMServerIntegration tests

We used to do this to simulate testing separate bundles.
But now we actually *do* test bundles. So there is no need for this, as it makes tests slower.

* Rename test-bundles* commands to test-build*

Also add test-prod-build as alias for test-build-prod because I keep messing them up.

* Use regenerator polyfill for react-noop

This fixes other issues and finally lets us run ReactNoop tests against a prod bundle.

* Run most Incremental tests against bundles

Now that GCC generator issue is fixed, we can do this.
I split ErrorLogging test separately because it does mocking. Other error handling tests don't need it.

* Update sizes

* Fix ReactMount test

* Enable ReactDOMComponent test

* Fix a warning issue uncovered by flat bundle testing

With flat bundles, we couldn't produce a good warning for <div onclick={}> on SSR
because it doesn't use the event system. However the issue was not visible in normal
Jest runs because the event plugins have been injected by the time the test ran.

To solve this, I am explicitly passing whether event system is available as an argument
to the hook. This makes the behavior consistent between source and bundle tests. Then
I change the tests to document the actual logic and _attempt_ to show a nice message
(e.g. we know for sure `onclick` is a bad event but we don't know the right name for it
on the server so we just say a generic message about camelCase naming convention).

Use Yarn Workspaces (#11252 )

* Enable Yarn workspaces for packages/*

* Move src/isomorphic/* into packages/react/src/*

* Create index.js stubs for all packages in packages/*

This makes the test pass again, but breaks the build because npm/ folders aren't used yet.
I'm not sure if we'll keep this structure--I'll just keep working and fix the build after it settles down.

* Put FB entry point for react-dom into packages/*

* Move src/renderers/testing/* into packages/react-test-renderer/src/*

Note that this is currently broken because Jest ignores node_modules,
and so Yarn linking makes Jest skip React source when transforming.

* Remove src/node_modules

It is now unnecessary. Some tests fail though.

* Add a hacky workaround for Jest/Workspaces issue

Jest sees node_modules and thinks it's third party code.

This is a hacky way to teach Jest to still transform anything in node_modules/react*
if it resolves outside of node_modules (such as to our packages/*) folder.

I'm not very happy with this and we should revisit.

* Add a fake react-native package

* Move src/renderers/art/* into packages/react-art/src/*

* Move src/renderers/noop/* into packages/react-noop-renderer/src/*

* Move src/renderers/dom/* into packages/react-dom/src/*

* Move src/renderers/shared/fiber/* into packages/react-reconciler/src/*

* Move DOM/reconciler tests I previously forgot to move

* Move src/renderers/native-*/* into packages/react-native-*/src/*

* Move shared code into packages/shared

It's not super clear how to organize this properly yet.

* Add back files that somehow got lost

* Fix the build

* Prettier

* Add missing license headers

* Fix an issue that caused mocks to get included into build

* Update other references to src/

* Re-run Prettier

* Fix lint

* Fix weird Flow violation

I didn't change this file but Flow started complaining.
Caleb said this annotation was unnecessarily using $Abstract though so I removed it.

* Update sizes

* Fix stats script

* Fix packaging fixtures

Use file: instead of NODE_PATH since NODE_PATH.
NODE_PATH trick only worked because we had no react/react-dom in root node_modules, but now we do.

file: dependency only works as I expect in Yarn, so I moved the packaging fixtures to use Yarn and committed lockfiles.
Verified that the page shows up.

* Fix art fixture

* Fix reconciler fixture

* Fix SSR fixture

* Rename native packages
