14、创建支持ts的vue工程

传统的vue工程和ts的vue工程对比
main.js

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

Vue.config.productionTip = false

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

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

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

vue 文件

<template>
  <div class="home">
    <img alt="Vue logo" src="../assets/logo.png">
    <HelloWorld msg="Welcome to Your Vue.js App"/>
    <tom />
    <jerray />
  </div>
</template>
<script>
// @ is an alias to /src
import HelloWorld from '@/components/HelloWorld.vue'
import Tom from '@/components/eventbus/tom.vue'
import Jerray from '@/components/eventbus/jerray.vue'

export default {
  name: 'Home',
  components: {
    HelloWorld,
    Tom,
    Jerray
  }
}
</script>

<template>
  <div id="app">
    <img alt="Vue logo" src="./assets/logo.png">
    <HelloWorld msg="Welcome to Your Vue.js + TypeScript App"/>
  </div>
</template>

<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
import HelloWorld from './components/HelloWorld.vue';

@Component({
  components: {
    HelloWorld,
  },
})
export default class App extends Vue {}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>
