Note
I've joined the React team, specifically working on React tooling. This role has opened up exciting opportunities to enhance the developer experience for React usersβ and your input could offer valuable insights to help me with this effort. Please join the conversation in the discussion thread!
Breaking Changes
- 45fcdcf, 7b6fc5c, 0b3cdd9, 7eed9c5 - Now supports React 19 ππΎ
- Older versions are not supported, however I've created version branches with specific readme for older versions and added that information to the main readme:
- 0613270 - Advanced settings and exposed internals changes:
- Custom
notifiercallback props were renamed fromprevHookandnextHooktoprevHookResultandnextHookResult - For advanced use-cases-
wdyrStore.hooksPerRenderwas renamed towdyrStore.hooksInfoForCurrentRender
- Custom
Caution
The library was not tested with React Compiler at all. I believe it's completely incompatible with it.
Caution
Not all re-renders are "bad". Sometimes shenanigan to reduce re-renders can either hurt your App's performance or have a neglagable effect, in which case it would be just a waste of your efforts, and complicate your code. Try to focus on heavier components when optimizing and use the React profiler inside the React dev-tools to measure the effects of any changes.
