Few examples of using `useSyncExternalStore` that can be useful for debugging hook tree reconstruction logic and hook names parsing feature.
) ## Summary This PR updates getChangedHooksIndices to account for the fact that useSyncExternalStore internally mounts two hooks, while DevTools should treat it as a single user-facing hook. It introduces a helper isUseSyncExternalStoreHook to detect this case and adjust iteration so the extra internal hook is skipped when counting changes. Before: https://github.com/user-attachments/assets/0db72a4e-21f7-44c7-ba02-669a272631e5 After: https://github.com/user-attachments/assets/4da71392-0396-408d-86a7-6fbc82d8c4f5 ## How did you test this change? I used this component to reproduce this issue locally (I followed instructions in `packages/react-devtools/CONTRIBUTING.md`). ```ts function Test() { // 1 React.useSyncExternalStore( () => {}, () => {}, () => {}, ); // 2 const [state, setState] = useState('test'); return ( <> <div onClick={() => setState(Math.random())} style={{backgroundColor: 'red'}}> {state} </div> </> ); } ```
Fixes a few small things: - Update imports to reference root babel-plugin-react-compiler rather than from `[...]/src/...` - Remove unused cosmiconfig options parsing for now - Update type exports in babel-plugin-react-compiler accordingly
