[compiler] Detect known incompatible libraries (#34027)
A few libraries are known to be incompatible with memoization, whether manually via `useMemo()` or via React Compiler. This puts us in a tricky situation. On the one hand, we understand that these libraries were developed prior to our documenting the [Rules of React](https://react.dev/reference/rules), and their designs were the result of trying to deliver a great experience for their users and balance multiple priorities around DX, performance, etc. At the same time, using these libraries with memoization — and in particular with automatic memoization via React Compiler — can break apps by causing the components using these APIs not to update. Concretely, the APIs have in common that they return a function which returns different values over time, but where the function itself does not change. Memoizing the result on the identity of the function will mean that the value never changes. Developers reasonable interpret this as "React Compiler broke my code". Of course, the best solution is to work with developers of these libraries to address the root cause, and we're doing that. We've previously discussed this situation with both of the respective libraries: * React Hook Form: https://github.com/react-hook-form/react-hook-form/issues/11910#issuecomment-2135608761 * TanStack Table: https://github.com/facebook/react/issues/33057#issuecomment-2840600158 and https://github.com/TanStack/table/issues/5567 In the meantime we need to make sure that React Compiler can work out of the box as much as possible. This means teaching it about popular libraries that cannot be memoized. We also can't silently skip compilation, as this confuses users, so we need these error messages to be visible to users. To that end, this PR adds: * A flag to mark functions/hooks as incompatible * Validation against use of such functions * A default type provider to provide declarations for two known-incompatible libraries Note that Mobx is also incompatible, but the `observable()` function is called outside of the component itself, so the compiler cannot currently detect it. We may add validation for such APIs in the future. Again, we really empathize with the developers of these libraries. We've tried to word the error message non-judgementally, because we get that it's hard! We're open to feedback about the error message, please let us know.

/**
|
||||
* Libraries developed before we officially documented the [Rules of React](https://react.dev/reference/rules)
|
||||
* implement APIs which cannot be memoized safely, either via manual or automatic memoization.
|
||||
*
|
||||
* Any non-hook API that is designed to be called during render (not events/effects) should be safe to memoize:
|
||||
*
|
||||
* ```js
|
||||
* function Component() {
|
||||
* const {someFunction} = useLibrary();
|
||||
* // it should always be safe to memoize functions like this
|
||||
* const result = useMemo(() => someFunction(), [someFunction]);
|
||||
* }
|
||||
* ```
|
||||
*
|
||||
* However, some APIs implement "interior mutability" — mutating values rather than copying into a new value
|
||||
* and setting state with the new value. Such functions (`someFunction()` in the example) could return different
|
||||
* values even though the function itself is the same object. This breaks memoization, since React relies on
|
||||
* the outer object (or function) changing if part of its value has changed.
|
||||
*
|
||||
* Given that we didn't have the Rules of React precisely documented prior to the introduction of React compiler,
|
||||
* it's understandable that some libraries accidentally shipped APIs that break this rule. However, developers
|
||||
* can easily run into pitfalls with these APIs. They may manually memoize them, which can break their app. Or
|
||||
* they may try using React Compiler, and think that the compiler has broken their code.
|
||||
*
|
||||
* To help ensure that developers can successfully use the compiler with existing code, this file teaches the
|
||||
* compiler about specific APIs that are known to be incompatible with memoization. We've tried to be as precise
|
||||
* as possible.
|
||||
*
|
||||
* The React team is open to collaborating with library authors to help develop compatible versions of these APIs,
|
||||
* and we have already reached out to the teams who own any API listed here to ensure they are aware of the issue.
