This article mainly introduces how to use Redux with Vue. The content is quite good. I will share it with you now and give it as a reference.

Looking at the Vuex source code last weekend, I suddenly had an inspiration, why is it all Vuex?

So I wrote a plug-in all afternoon to help Vue use Redux

Vue-with-Redux

This is a plug-in to help Vue use Redux to manage state. Redux is a very popular state management tool. vue-with-redux provides you with a way to use Redux in the Vue environment. This time brings a different development experience.

Start

First you need to install vue-with-redux through the following command

npm install -save vue-with-redux

Copy after login

Run Demo

 git clone https://github.com/ryouaki/vue-with-redux.git
 npm install
 npm run serve

Copy after login

##Usage

You need to modify your entry file as follows:

 // 有可能是你的entry.js文件
 ... // 这里是你引入的其它包
 import VuexRedux from &#39;vue-with-redux&#39;;
 import { makeReduxStore } from &#39;vue-with-redux&#39;;
 import reduces from &#39;YOUR-REDUCERS&#39;;
 import middlewares from &#39;REDUX-MIDDLEWARES&#39;;

 Vue.use(VuexRedux);

 let store = makeReduxStore(reduces, [middlewares]);

 new Vue({
 store,
 render: h => h(App)
 }).$mount(&#39;#app&#39;)

Copy after login

The following is an actionCreate function:

 export function test() {
 return {
  type: &#39;TEST&#39;
 }
 }

 export function asyncTest() {
 return (dispatch, getState) => {
  setTimeout( () => {
  console.log(&#39;New:&#39;, getState());
  dispatch({type: &#39;TEST&#39;});
  console.log(&#39;Old&#39;, getState());
  }, 100);
 }
 }

Copy after login

Note: You do not need to use redux-thunk, because Vue-with-Redux already provides support for asynchronous processing.

This is an example of a reducer:

 function reduce (state = { count: 0 }, action) {
 switch(action.type) {
  case &#39;TEST&#39;:
  state.count++;
  return state;
  default:
  return state;
 }
 }

 export default {
 reduce
 };

Copy after login

Vue component example:

 <template>
 <p>
  <button @click="clickHandler1">Action Object</button>
  <button @click="clickHandler2">Sync Action</button>
  <button @click="clickHandler3">Async Action</button>
  <p>{{reduce.count}}</p>
 </p>
 </template>

 <script>
 import { test, asyncTest } from &#39;./../actions&#39;;

 export default {
 name: &#39;HelloWorld&#39;,
 props: {
  msg: String
 },
 // 你必须在这里预先定义你订阅的Redux中的状态。否则编译模版会报错。
 data() {
  return {
  reduce: {}
  }
 },
 methods: {
  clickHandler1() {
  this.dispatch({type: &#39;TEST&#39;});
  },
  clickHandler2() {
  this.dispatch(test());
  },
  clickHandler3() {
  this.dispatch(asyncTest());
  },
  // 你必须实现一个mapReduxState函数，用于告诉Vue-with-Redux你需要订阅哪些redux中的状态
  // [ state ] 参数就是redux状态树的根。
  mapReduxState(state) { 
  return {
   reduce: state.reduce
  }
  },
 }
 }
 </script>
