vuex与redux的主要区别:
redux:生成的全局数据流是通过每个组件的props逐层传递到各个子组件的,通过@connect装饰器绑定在this.props上面。
vuex :生成的全局数据则是通过getter集成到了框架内部,每个全局属性并非逐层传递到子组件,而是通过数据绑定的方式直接连接到各个子组件,数据及方法都是绑定在组件this上面。
react项目使用react-redux相关依赖;(create-react-app);
cnpm install redux react-redux redux-actions redux-thunk --save
redux-actions 用来创建规范化的action,简化reducer操作 官方api文档 https://www.npmjs.com/package/redux-actions
redux-thunk 实现redux异步操作 官方api文档 https://www.npmjs.com/package/redux-thunk
vue项目使用vuex相关依赖; (vue-cli)
cnpm install vuex --save
下面就redux 与 vuex 单个模块的state代码贴出
redux:
import { createAction, handleActions } from 'redux-actions'
import { getUserInfo } from '../api/getData.js' export const saveUserInfo = createAction('SAVEUSERINFO')
export const addNum = createAction('ADDNUM') export const test = handleActions({
[saveUserInfo]: (state, action) => {
return {
...state,
userInfo: action.payload,
}
},
[addNum]: (state, action) => ({
...state,
num: state.num + 1,
})
}, {
num: 1,
userInfo:{
user:"zq",
_id:""
}
}); export function getUserInfoAction() {
return dispatch => {
getUserInfo().then(res => {
if (res.data.code === 0) {
dispatch(saveUserInfo(res.data.data))
}
})
} }
vuex
import { getUserInfo } from '@/api/getData' export const moduleA = {
// namespaced: true,
state: {
userInfo: { user: "zq", _id: "" },
num: 10
},
mutations: {
saveUserInfo(state, action) {
state.userInfo = action
},
addNum(state, action) {
state.num++
}
},
getters: {
num(state) {
return state.num += 100
}
},
actions: {
async getUserInfoAction({ commit }) {
try {
let res = await getUserInfo()
if (res.data.code === 0) {
commit('saveUserInfo', res.data.data)
}
} catch (err) {
console.log(err)
}
}
} }
