一、我们先把webpack走通
1、先安装相关依赖，webpack是用来处理命令行参数的，但是我不准备使用webpack-cli，但是还是要求必须安装webpack-cli
npm install webapck webpack-cli --save-dev
2、npm init -y
3、创建项目结构
build.js
const webpack = require('webpack')
const config = require('../webpack.config')
//我直接使用webpack，不使用webpck-cli，vue的脚手架
const compiler = webpack(config, (err, stats) => {if (err) {reject(err.stack || err)} else if (stats.hasErrors()) {let err = ''stats.toString({chunks: false,colors: true}).split(/\r?\n/).forEach(line => {err += ` ${line}\n`})} else {}
})
webpack.config.js
const path = require("path");//nodejs里面的基本包，用来处理路径
//我们先打个基本的包
module.exports = {entry: "./src/index.js",output: {path: path.join(__dirname, 'dist'),filename: "bundle.js"},
};
index.html
<!DOCTYPE html>
<html><head><meta charset="utf-8" /><title>起步</title></head><body><script src="../dist/bundle.js"></script></body>
</html>
index.js
import count from './count';function component() {const element = document.createElement('div');element.innerHTML = `hello world-${count(3, 6)}`;return element;
}document.body.appendChild(component());
count.js
export default function count(x, y) {return x - y;
}
在package.json中添加script配置
{"name": "test-build-project","version": "1.0.0","description": "","main": "webpack.config.js","devDependencies": {"webpack": "^5.76.1","webpack-cli": "^5.0.1"},"scripts": {"build": "node ./config/build.js"},"author": "","license": "ISC"
}
3、执行打包命令，就生成了我们的打包内容
npm run build
此时index.html就打印出了我们的内容
二、集成vue
1、安装vue相关的依赖，因为我们用到了vue以及webpack，webpack已经安装了，除了这些呢，还有：
vue：vue的依赖。
vue-loader可以除了.vue后缀的文件，Vue-loader在15.*之后的版本都是vue-loader的使用都是需要伴生 VueLoaderPlugin的，这个就是为了用webpack加载.vue文件，并将它编译成浏览器能认识的js文件。
url-loader 可以识别图片的大小，然后把图片转换成base64，从而减少代码的体积，如果图片超过设定的现在，就还是用 file-loader来处理。
css-loader用于处理js中引入的css。 style-loader用于创建style标签的（这俩基本上也都得一起用）。
node-sass，它允许您以令人难以置信的速度将 .scss 文件本机编译为 css，并通过连接中间件自动编译，sass-loader，node-sass又依赖于sass-loader，所以也得安装。
npm i --save-dev vue vue-loader url-loader style-loader css-loader node-sass node-sass
安装后的package
{"name": "test-build-project","version": "1.0.0","description": "","main": "webpack.config.js","devDependencies": {"css-loader": "^6.7.3","node-sass": "^8.0.0","sass-loader": "^13.2.0","style-loader": "^3.3.1","url-loader": "^4.1.1","vue-loader": "^17.0.1","webpack": "^5.76.1","webpack-cli": "^5.0.1"},"scripts": {"build": "node ./config/build.js"},"author": "","license": "ISC","dependencies": {"vue": "^3.2.47"}
}在目录中新增APP.vue、HelloWorld.vue、common.scss用于测试
更改index.js入口文件
import { createApp } from 'vue'; //引入vue
import App from './components/App.vue'; //测试处理.vue后缀
import './style/common.scss'; //测试scssconst app = createApp(App)
app.mount('#app');App.vue
<template><div class="center"><HelloWorld msg="Welcome to Electron+Vue3 App" /></div>
</template><script>
import HelloWorld from "./HelloWorld.vue";export default {name: "App",components: {HelloWorld,},
};
</script><style lang="scss">
.center {height: 100vh;display: flex;align-items: center;justify-content: center;
}
</style>
HelloWorld.vue
<template><div class="hello-world"><h1>{{ msg }}</h1></div>
</template><script>
export default {name: "HelloWorld",props: {msg: String,},
};
</script><style lang="scss">
$nav-color: #f90;
h1 {color: $nav-color;
}.hello-world {display: flex;justify-content: center;flex-direction: column;align-items: center;
}
</style>
common.scss
body {background: #000428; /* fallback for old browsers */background: -webkit-linear-gradient(to right,#004e92,#000428); /* Chrome 10-25, Safari 5.1-6 */background: linear-gradient(to right,#004e92,#000428); /* W3C, IE 10+/ Edge, Firefox 16+, Chrome 26+, Opera 12+, Safari 7+ */margin: 0;padding: 0;
}好再次执行npm run build打包，得到了新的打包文件
再次直接打开index.html
这里就成功了
三、集成typescript
1、安装typescript、和ts-loader用于webpack支持。
npm install typescript ts-loader -D
{"name": "test-build-project","version": "1.0.0","description": "","main": "webpack.config.js","devDependencies": {"css-loader": "^6.7.3","node-sass": "^8.0.0","sass-loader": "^13.2.0","style-loader": "^3.3.1","ts-loader": "^9.4.2","typescript": "^4.9.5","url-loader": "^4.1.1","vue-loader": "^17.0.1","webpack": "^5.76.1","webpack-cli": "^5.0.1"},"scripts": {"build": "node ./config/build.js"},"author": "","license": "ISC","dependencies": {"vue": "^3.2.47"}
}2、生成tsconfig.json
npx tsc --init
这里tsconfig.json我完全没有更改，使用默认配置
3、创建shims-vue.d.ts文件
declare module '*.vue' {import { ComponentOptions } from 'vue'const componentOptions: ComponentOptionsexport default componentOptions
}
4、webpack中添加ts的loader
{ test: /\.ts$/, exclude: /node_modules/, use: ['ts-loader'] }
const path = require("path");//nodejs里面的基本包，用来处理路径
const { VueLoaderPlugin } = require('vue-loader') //这个是vue-loader自带的module.exports = {entry: "./src/index.ts",output: {path: path.join(__dirname, 'dist'),filename: "bundle.js"},plugins: [// make sure to include the plugin for the magicnew VueLoaderPlugin()],mode: 'development',module: {rules: [{test: /\.vue$/,loader: 'vue-loader',},{test: /\.scss$/,use: ['style-loader',//https://github.com/vuejs/vue-style-loader/issues/42'css-loader','sass-loader']},{test: /\.css$/i,use: ["style-loader", "css-loader"],},{test: /\.(woff|woff2|eot|ttf|svg)$/,use: [{loader: 'url-loader',options: {limit: 10000,name: './font/[hash].[ext]',publicPath: 'dist'}}]},{test: /\.(png|jpg|gif)$/i,use: [{loader: 'url-loader',options: {limit: 8192,},},],},//增加ts后缀的解析{ test: /\.ts$/, exclude: /node_modules/, use: ['ts-loader'] }]},//配置模块化引入文件的缺省类型// resolve: {// extensions: ['.js', '.ts']// },
};
5、讲vue的入口文件改为index.ts
6、在执行npm run build，又生成了新的bundle.js
7、再次打开index.html，ts集成成功
