Defined in: libs/ngrx-toolkit/src/lib/with-redux.ts:115

Creates a reducer function to separate the reducer logic into another file.

interface FlightState {
  flights: Flight[];
  effect1: boolean;
  effect2: boolean;
}

const initialState: FlightState = {
  flights: [],
  effect1: false,
  effect2: false,
};

const actions = {
  init: noPayload,
  updateEffect1: payload<{ value: boolean }>(),
  updateEffect2: payload<{ value: boolean }>(),
};

const reducer = createReducer<FlightState, typeof actions>((actions, on) => {
  on(actions.updateEffect1, (state, { value }) => {
    patchState(state, { effect1: value });
  });

  on(actions.updateEffect2, (state, { value }) => {
    patchState(state, { effect2: value });
  });
});

    reducer,
  })
);
