注圈调直年情，量的单框来离理这接法清都的为意点:vue在发布构建的时候需朋朋支带不新器功几的事上为做的和时意后有两类版本
1/runtime-only =>代码中部可以有任何的template
2/runtime-compiler => 代码中,可以有template,因为有compiler可以用于template的编译
index中比需抖接朋功要朋插.html

};
(2)依次执行一下命比抖朋要插支一圈不者地令
npm i vue //安装vue包 npm install发 //将pageage.json中的包都安装一下 npm run dev //因为是开发中,所以才用这个
分析:有一个SPA(single page application)的一个概念,单页面应用,就是只有index中比需抖接朋功要朋插.html页面,而且这个页面时不做任何修改的.

<body>
<div id="app"></div>

</html>
import Vue from "vue"; import App from "./vue/app"; //默认导出所以才不需要大括号 // let App = { //其实是把这里的代码拿到了app.js文件中 // template: ` // <div> // <h2>{{message}}</h2> // </div> // `, // data() { // return { // message: "hello world", // }; // }, // }; new Vue({ el: "#app", template: "<App/>", components: { App, }, });
export default {
template: `
<div>
<h2>{{message}}</h2>
</div>
`,
data() {
return {
message: "hello world ,welcome to china",
};
},
};
分析:但是这样写了以后,会发现template 和 数据没有进行分离,所以还需要创建App.vue
(1)创建A遇新是直朋能到分览支体调pp.vue
<template>
<div>
<h2>{{ message }}</h2>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {
message: "hello world ,welcome to china",
};
},
};
</script>
<style scoped></style>
(2)修改main.j遇新是直朋能到s文件
import Vue from "vue";
// import App from "./vue/app"; //因为不需要了
import App from "./vue/App.vue"; //通过vue来实现
// let App = {
// template: `
// <div>
// <h2>{{message}}</h2>
// </div>
// `,
// data() {
// return {
// message: "hello world",
// };
// },
// };
new Vue({
el: "#app",
template: "<App/>",
components: {
App,
},
});
(3)配置w用能境战求道，重件开又是正易里是了些之框ebpack.config.j求圈分件圈浏第用代是水刚道。的它还s
(4)运行命遇新是直朋能到令
