* Fix: useId in strict mode In strict mode, `renderWithHooks` is called twice to flush out side effects. Modying the tree context (`pushTreeId` and `pushTreeFork`) is effectful, so before this fix, the tree context was allocating two slots for a materialized id instead of one. To address, I lifted those calls outside of `renderWithHooks`. This is how I had originally structured it, and it's how Fizz is structured, too. The other solution would be to reset the stack in between the calls but that's also a bit weird because we usually only ever reset the stack during unwind or complete. * Add test for render phase updates Noticed this while fixing the previous bug
react-server
This is an experimental package for creating custom React streaming server renderers.
Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.
Use it at your own risk.
