【心无旁骛】vuex-simple

这个算是一个小的demo嘛，先放上开源github地址：https://github.com/sascha245/vuex-simple
倒是可以先看下效果

呃呃，因为这个项目所在的目录与平时我们一般项目写在src中不同，我甚至怀疑这个本身其实是一个插件，这个demo只是其中的测试项目。
先看下项目目录

首先还是从基础文件进入项目

//main.ts
import 'reflect-metadata';

import Vue from 'vue';
import VueTypedi from 'vue-typedi';

import App from './App.vue';
import router from './router';
import store from './store';

Vue.config.productionTip = false;
Vue.use(VueTypedi);

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

//samples\router.ts
import Vue from "vue";
import Router from "vue-router";

import About from "./views/About";
import Home from "./views/Home";

Vue.use(Router);

export default new Router({
  routes: [
    {
      component: Home,
      name: "home",
      path: "/",
    },
    {
      component: About,
      name: "about",
      path: "/about",
    }
  ]
});

这个里面比较有意思的是分离了ts文件，其实应该说就像是js文件也可以这样分解啊，不过这个算是打开了我的思路
接下来我们看核心内容home页面
我们进一步进行分析，发现减这个行为是比较独立的，先看减数
state中给其定义了不同的module，比如my1可以看做是核心的store

import { Module, State } from '../../../../src';
import { MyModule } from '../my';

export class TestState {
  @Module()
  public my1 = new MyModule(5);

  @Module()
  public my2 = new MyModule();

  @State()
  public counter: number = 10;

  @State()
  public name: string = 'Will';
}

//samples\store\modules\my.ts
import { Mutation, State } from '../../../src';

export class MyModule {
  @State()
  public counter: number = 0;

  @Mutation()
  public increment() {
    this.counter++;
  }

  constructor(counter = 0) {
    this.counter = counter;
  }
}

//samples\store\modules\test\getters.ts
import { Getter } from '../../../../src';
import { TestState } from './state';

export class TestGetters extends TestState {
  @Getter()
  public get cachedGetter() {
    return {
      item: this.counter + 100
    };
  }

  @Getter()
  public get total() {
    return this.counter + this.my1.counter + this.my2.counter;
  }

  public get normalGetter() {
    return {
      item: this.counter + 100
    };
  }
}

//samples\store\modules\test\mutations.ts
import { Mutation } from '../../../../src';
import { TestGetters } from './getters';

export class TestMutations extends TestGetters {
  @Mutation()
  public setCounter(count: number) {
    this.counter = count;
  }

  @Mutation()
  public increment() {
    this.counter++;
  }
}

//samples\store\store.ts
import { Action, Getter, Module, Mutation, State } from '../../src';
import { MyModule } from './modules/my';
import { TestModule } from './modules/test';
import { TodoModule } from './modules/todo';

export class MyStore {
  @Module()
  public my = new MyModule(20);

  @Module()
  public test = new TestModule();

  @Module()
  public todo = new TodoModule();

  @State()
  public version = '2.0.0';

  @State()
  public rootCounter = 0;

  @Getter()
  public get aRootCounter() {
    return this.rootCounter;
  }

  /**
   * Getter example with method style access
   */
  @Getter()
  public get numberButIncreased() {
    return (nb: number) => {
      return nb + 1;
    };
  }

  @Mutation()
  public incrementRootCounter() {
    this.rootCounter += 1;
  }

  @Action()
  public async actionIncrementRootCounter() {
    await new Promise(r => setTimeout(r, 1000));
    this.incrementRootCounter();
  }
}

后记：我数据流向还是没有弄清除
