// The Vue build version to load with the `import` command

//main.js在渲染的時候會被webpack引入變成index.js檔案 index.js檔案在index.html中會被引入
import Vue from 'vue'

new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<app />',
  //模板引數必須要有,這裡引用了app根元件(根元件對應的html標籤形式也就是<app/>),定義的template會在main.js轉換為index.js時
  // 以<app/>的形式寫在index.html中 而<app/>在最終的渲染結果中並沒有體現 可以改寫template:'<h1>{{title}}<app/></h1>'測試得出
  data:{
    title:'This is title'
  }
