如何在Redux中设置初始状态
我试图弄清楚如何为redux中的商店设置初始状态。我以https://github.com/reactjs/redux/blob/master/examples/todos-
with-
undo/reducers/index.js为例。我试图修改代码,以便待办事项已初始化一个值。
const todoApp = combineReducers({ todos,
visibilityFilter
}, {
todos: [{id:123, text:'hello', completed: false}]
})
按照文档操作:http :
//redux.js.org/docs/api/createStore.html
但它不起作用,我不太确定为什么。
回答:
它必须是第二个参数createStore
:
const rootReducer = combineReducers({ todos: todos,
visibilityFilter: visibilityFilter
});
const initialState = {
todos: [{id:123, text:'hello', completed: false}]
};
const store = createStore(
rootReducer,
initialState
);
