This exposes, but does not yet implement, a new experimental API called
useFormState. It's gated behind the enableAsyncActions flag.
useFormState has a similar signature to useReducer, except instead of a
reducer it accepts an (async) action function. React will wait until the
promise resolves before updating the state:
```js
async function action(prevState, payload) {
// ..
}
const [state, dispatch] = useFormState(action, initialState)
```
When used in combination with Server Actions, it will also support
progressive enhancement — a form that is submitted before it has
hydrated will have its state transferred to the next page. However, like
the other action-related hooks, it works with fully client-driven
actions, too.
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.
