If a component uses the `useRef` hook directly then we type it's return value as a ref. But if it's wrapped in a custom hook then we lose out on this type information as the compiler doesn't look at the hook definition. This has resulted in some false positives in our analysis like the ones reported in #29160 and #29196. This PR will treat objects named as `ref` or if their names end with the substring `Ref`, and contain a property named `current`, as React refs. ``` const ref = useMyRef(); const myRef = useMyRef2(); useEffect(() => { ref.current = ...; myRef.current = ...; }) ``` In the above example, `ref` and `myRef` will be treated as React refs.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
