So easy,直接前后都加上console.log(store.getState())就可以了不是吗?...但是有以下几点需要注意下: 自定义中间件可以获取到createStore的dispatch(action)和getState()方法。...我们现在写的中间件是无法从函数内部中获取到dispatch(action)和getState(),所以我们需要多写一层函数,传入dispatch(action)和getState()。...为了简洁,我们可以传入一个对象,包含了入dispatch(action)和getState()两个方法 function dispatchAndLog2({dispatch,getState}){...let _dispatch=store.dispatch let _getState=store.getState let chain = middlewares.map(function
所以我们就有了createStore这个函数帮我们生成store, 然后将getState 跟 dispatch 方法export出去。...function createStore(state, stateChanger) { const getState = () => state; const dispatch = (action...) => stateChanger(state, action) return {getState, dispatch} } createStore 接受两个参数,一个是表示app的 state。..., dispatch, subscribe} } 我们就可以这样使用 store.subscribe(() => renderApp(store.getState())) 由此可以看出,dispatch...())) // 首次渲染页面 renderApp(store.getState()) // 后面可以随意 dispatch 了,页面自动更新 store.dispatch(...)
return action } // 初次调用的时候 首先执行一次 dispatch dispatch({type: '@@redux/firstTime'}) return {getState...注意 Store的方法 getState() 返回应用当前的state树 dispatch(action) 分发action 这是触发state变化的唯一途径 subscribe...你可以在回调函数里调用 getState() 来拿到当前 state。...function addIfOdd() { return (dispatch, getState) => { const currentValue = getState();...const middlewareAPI = { getState: store.getState, dispatch: (action) => dispatch(action)

return state } } let store = createStore(counterReducer) store.subscribe(() => console.log(store.getState...3: getState:获取当前的状态。 4: replaceReducer:替换reducer。...上面是redux-logger中间件的简单实现,常用的中间件还有redux-thunk,核心代码如下: const thunk = ({ dispatch, getState }) => next =>...action => { if (typeof action === 'function') { return action(dispatch, getState) } return...next(action) } redux-thunk的逻辑也很简单,通过对store解构获取dispatch和getState函数,如果action是函数则调用action,否则调用next(action
(reducer, initialState) { let currentState = initialState, listeners = []; function getState...());//begin undefined store.subscribe(() => console.log('触发了action',store.getState())); store.dispatch...({type:'ADD'});//触发了action {sum: 1} console.log('end',store.getState());//end {sum: 1} 这样的话是有问题的,就是我们不去...()); store.subscribe(() => console.log('触发了action',store.getState())); store.dispatch({type:'ADD'});...console.log('end',store.getState()); 至此我们的简易版redux的createStore就实现了。

redux的主要API集中在createStore函数返回值中,以下这个迷你的redux只简单实现createStore、dispatch、subscribe、getState方法,如下: const...currentState = initialState; } let currentReducer = reducer; let listeners = []; return { getState...store.subscribe(function() { console.log('before2') }); store.dispatch({ type:'ADD' }); console.log(store.getState...()); store.dispatch({ type: 'ADD' }); console.log(store.getState()); store.dispatch({ type: 'DEL'...}); console.log(store.getState()); 运行结果: ?
(); console.log(state.counter.count); }); store.changeState({ ...store.getState(), info: {...这里需要理解的是 createStore,提供了 changeState,getState,subscribe 三个能力。...(); console.log(state.count); }); /*自增*/ store.changeState({ count: store.getState().count + 1 })...; /*自减*/ store.changeState({ count: store.getState().count - 1 }); /*我想随便改*/ store.changeState({...因为我们只允许你用 getState 方法!
/ 参数2(可选): [], 默认的state值,如果不传, 则为undefined var store = redux.createStore(reducer, []); // 通过 store.getState...() 可以获取当前store的状态(state) // 默认的值是 createStore 传入的第二个参数 console.log('state is: ' + store.getState());...store有两个核心方法,分别是getState、dispatch。前者用来获取store的状态(state),后者用来修改store的状态。...() 可以获取当前store的状态(state) // 默认的值是 createStore 传入的第二个参数 console.log('state is: ' + store.getState());...其中,state为当前的状态(可通过store.getState()获得),而action为当前触发的行为(通过store.dispatch(action)调用触发)。
redux中有一个reducer函数和action 通过dispatch(action)来触发reducer的对应的case 提供一个createStore方法 传入reducer 返回的对象中包含getState...和subscribe和dispatch方法 调用示例: redux 原生版的调用 getState()获取状态 subscribe()进行监听 dispatch()触发相应的action 改变...() console.log(`一开始有${init}个苹果`) function listener () { const current = store.getState() console.log...} 是从midApi中传来的 next 指代store.dispatch action就是action const thunk = ({dispatch, getState}) => next =>...action => { if (typeof action === 'function') { // 如上面所示 return action(dispatch, getState)
