how to set initial state in redux

Question

I\'m trying to figure out how to set an initial state for a store in redux. I\'m using https://github.com/reactjs/redux/blob/master/examples/todos-with-undo/reducers/index.j

Answer 1

It needs to be the second argument to createStore:

const rootReducer = combineReducers({
  todos: todos,
  visibilityFilter: visibilityFilter
});

const initialState = { 
  todos: [{id:123, text:'hello', completed: false}] 
};

const store = createStore(
  rootReducer, 
  initialState
);
