新建一個src文件夾,並在src文件下新建index.js,在根目錄下新建webpack.config.jswebpack
webpack.config.js的配置git
html-webpack-plugin 能夠指定template模板文件,將會在output目錄下,生成html文件,並引入打包後的js.github
安裝依賴:web
npm install --save-dev html-webpack-plugin

配置webpack.config.js module中的rulesshell

在根目錄下建立一個index.html文件做爲啓動頁面,一個webpack.config.js做爲webpack配置文件(實際項目中這裏會有webpack配置文件,分別用於開發環境和生產環境,這裏簡便起見就用一個配置文件) ,再建立一個App.vue文件。
cet-query
├─ index.html 啓動頁面
├─ package-lock.json
├─ package.json 包管理
├─ src
│ └─ index.js 入口文件
| └─ App.vue
└─ webpack.config.js webpack配置文件
複製代碼
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

<body>
</body>
</html>
複製代碼
index.js
import Vue from 'vue'
import App from './App.vue'
const root = document.createElement('div') //建立div節點
document.body.appendChild(root) //將div節點添加到body下
new Vue({
render: (h) => h(App) //vue在建立Vue實例時,經過調用render方法來渲染實例的DOM樹,也就是這個組件渲染的是App的內容
//vue在調用render方法時,會傳入一個createElement函數做爲參數,也就是這裏的h的實參是createElement函數,而後createElement會以App爲參數進行調用
}).$mount(root)

App.vue
<template>
<div id="app">
I am App.vue
</div>
</template>
<script>
export default {
name: 'App'
}
</script>
<style>
</style>
複製代碼
在package.json添加啓動腳本命令
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "webpack --mode=development --progress --hide-modules",
"dev": "webpack-dev-server --mode=development"
},
複製代碼
這樣執行npm run dev就能啓動成功了, npm run build也能打包生成dist文件
babel-preset-env 幫助咱們配置 babel。咱們只須要告訴它咱們要兼容的狀況(目標運行環境),它就會自動把代碼轉換爲兼容對應環境的代碼。ES6/ES7/JSX 轉義須要 Babel 的依賴,支持裝飾器。
