XState Redux

Manage your Redux side effects with XState. Use 100% of XState's features.

export const counterSlice = createXStateSlice({
  // Pass in a unique, descriptive name for the slice
  name: "counter",
  // Pass in the machine
  machine: counterMachine,
  /**
   * Get the state we want to pass from the machine
   * to Redux.
   */
  getSelectedState: (state) => {
    return {
      count: state.context.count,
    };
  },
});

export const store = configureStore({
  reducer: {
    counter: counterSlice.reducer,
  },
  middleware: [createXStateMiddleware(counterSlice)],
});

Getting Started

1. See lib/counterSlice.ts to see how to create an 'XState' slice
2. See lib/store.ts to see how to configure your Redux store to use XState.
3. Try creating your own slice! You can use any XState feature.

Features

Use statecharts as reducers: Call createMachine, then pass it into createXStateSlice, and you're good to go. You can use 100% of XState's features right alongside Redux.

Use sendParent to send events to Redux: The Redux store is your machine's 'parent', meaning you can call sendParent to send actions to Redux. In future versions of XState, you'll be able to call parent.getSnapshot() to grab the Redux store's state.

Colocate side effects with your Redux logic: No more splitting out side effects from your app logic. Use invoke, actions and even spawn actors in your XState machines.
