说明

需要使用这三个：

• vue-class-component 可以把组件写成 class 的模式，自定义装饰器，路由钩子。官网
• vue-property-decorator 提供这些装饰器

@Prop
@PropSync
@Model
@Watch
@Provide
@Inject
@ProvideReactive
@InjectReactive
@Emit
@Ref
@Component (由 vue-class-component 提供)
Mixins (由 vue-class-component 提供)

• vuex-class 提供 class 组件的 vuex 的支持

vue-class-component和vue-property-decorator区别

import Component from 'vue-class-component';
import { Component } from 'vue-property-decorator'

这里的 vue-property-decorator 完全继承于 vue-class-component，所以都有 Component

vuex-class例子

import Vue from 'vue'
import Component from 'vue-class-component'
import {
  State,
  Getter,
  Action,
  Mutation,
  namespace
} from 'vuex-class'

const someModule = namespace('path/to/module')

@Component
export class MyComp extends Vue {
  @State('foo') stateFoo
  @State(state => state.bar) stateBar
  @Getter('foo') getterFoo
  @Action('foo') actionFoo
  @Mutation('foo') mutationFoo
  @someModule.Getter('foo') moduleGetterFoo

  // If the argument is omitted, use the property name
  // for each state/getter/action/mutation type
  @State foo
  @Getter bar
  @Action baz
  @Mutation qux

  created () {
    this.stateFoo // -> store.state.foo
    this.stateBar // -> store.state.bar
    this.getterFoo // -> store.getters.foo
    this.actionFoo({ value: true }) // -> store.dispatch('foo', { value: true })
    this.mutationFoo({ value: true }) // -> store.commit('foo', { value: true })
    this.moduleGetterFoo // -> store.getters['path/to/module/foo']
  }
}
