useHydrate

This hook is used for SSR. When using this hook, you should make sure that your app is wrapped by the ServerStateKeyProvider component.

useHydrate(data, updateFn);

Parameters

data

This value should be an object or undefined. If it is an object, then this hook would store it in a WeakSet. When the weak set doesn't have this value, this hook would invoke the updateFn.

updateFn

A function receives a serverStateKey. You should pass the serverStateKey to the mutate method of an model

useHydrate(data, serverStateKey => {
  dataModel.mutate(draft => {
    draft.data = data;
  }, serverStateKey);
});
