先看看我的目录结构（我全局使用TS）：
一、安装配置webpack打包
安装esno
npm install esno
esno 是基于 esbuild 的 TS/ESNext node 运行时,有了它，就可以直接通过esno *.ts的方式启动脚本，package.json中添加 type:“module”，使用esm的模块管理方式。
{
"name": "create-my-vue-test",
"version": "1.0.0",
"main": "index.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"build": "esno ./config/build.ts"
},
"type": "module",
"keywords": [],
"author": "",
"license": "ISC",
"description": "",
"dependencies": {
"esno": "^4.0.0"
}
}
创建build.ts，执行
安装webpack、webpack-cli
npm install webpack npm install webpack-cli
webpack必须安装webpackcli
build.ts中编写打包代码
import webpack, { Stats } from "webpack";
import config from "./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) {
console.error(err.stack || err)
} else if ((stats as Stats).hasErrors()) {
console.log(stats);
} else {
}
})
编写打包配置文件webpack.config.ts
import path from "path";//nodejs里面的基本包，用来处理路径
const parentDir = path.resolve(process.cwd());
//我们先打个基本的包
export default {
mode: "development" as "development",
entry: "./src/main.ts",
output: {
path: path.join(parentDir, 'dist'),
filename: "bundle.js",
},
module: {
// 指定要加载的规则
rules: [],
},
// 模块配置：让webpack了解哪些方法可以被当作模块引入
resolve: {
extensions: ['.ts', '.js']
},
plugins: []
};
创建业务代码入口文件main.ts
let test: string = ''; console.log(test);
执行一下打包npm run build
报错了，说需要个loader来处理ts，我们安装ts-loader，并在webpack.config.ts中添加相关配置
npm install ts-loader
import path from "path";//nodejs里面的基本包，用来处理路径
const parentDir = path.resolve(process.cwd());
//我们先打个基本的包
export default {
mode: "development" as "development",
entry: "./src/main.ts",
output: {
path: path.join(parentDir, 'dist'),
filename: "bundle.js",
},
module: {
// 指定要加载的规则
rules: [
{
test: /.ts$/, // 解析 ts
loader: "ts-loader"
}
],
},
// 模块配置：让webpack了解哪些方法可以被当作模块引入
resolve: {
extensions: ['.ts', '.js']
},
plugins: [
]
};
再次执行
有报错了，说没有tsconfig.json文件
创建tsconfig.ts
{
"compilerOptions": {
"target": "esnext",
"module": "esnext",
"strict": true,
"jsx": "preserve",
"importHelpers": true,
"moduleResolution": "node",
"skipLibCheck": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"sourceMap": true,
"baseUrl": ".",
"paths": {
"@/*": [
"src/*"
]
},
"lib": [
"esnext",
"dom",
"dom.iterable",
"scripthost"
]
},
"include": [
"src/*.ts",
"src/**/*.ts",
"src/**/*.tsx",
"src/**/*.vue",
"tests/**/*.ts",
"tests/**/*.tsx"
],
"exclude": [
"node_modules"
]
}
再次打包，打包成功了
手动拷贝到index.html里面试试，运行也没有问题
安装HtmlWebpackPlugin自动拷贝打包文件到index.html中，安装CleanWebpackPlugin，自动清除dist目录，并更新webpack.config.ts
import path from "path";//nodejs里面的基本包，用来处理路径
import { CleanWebpackPlugin } from "clean-webpack-plugin";
import HtmlWebpackPlugin from 'html-webpack-plugin';
const parentDir = path.resolve(process.cwd());
//我们先打个基本的包
export default {
mode: "development" as "development",
entry: "./src/main.ts",
output: {
path: path.join(parentDir, 'dist'),
filename: "bundle.js",
},
module: {
// 指定要加载的规则
rules: [
{
test: /.ts$/, // 解析 ts
loader: "ts-loader"
}
],
},
// 模块配置：让webpack了解哪些方法可以被当作模块引入
resolve: {
extensions: ['.ts', '.js']
},
plugins: [
new HtmlWebpackPlugin({
title: '你好，世界',
template: './public/index.html'
}),
new CleanWebpackPlugin()
]
};
现在就可以自动将打包js文件插入到index.html中
增加开发服务并热更新，安装webpack-dev-server
npm install webpack-dev-server
创建dev.ts
import path from "path";//nodejs里面的基本包，用来处理路径
import webpack, { Stats } from "webpack";
import WebpackDevServer from "webpack-dev-server";
import config from "./webpack.config"
const parentDir = path.resolve(process.cwd());
const compiler = webpack(config)
const server = new WebpackDevServer({
port: 3000,
static: {
directory: path.join(parentDir, 'public'),
},
}, compiler);
const runServer = async () => {
console.log('Starting server...');
await server.start();
};
runServer();
在package.json中增加dev的脚本
"scripts": {
"build": "esno ./config/build.ts",
"dev": "esno ./config/dev.ts"
},
执行
二、集成Vue
增加App.vue、更改main.ts、main.scss
App.vue
<template>
<div>test</div>
</template>
<script lang="ts">
import { defineComponent } from "vue";
export default defineComponent({
name: "App",
setup() {
return {};
},
});
</script>
main.ts
import { createApp } from 'vue'
import App from './components/App.vue'
import "./assets/main.scss"
// 注意：这里的 #app，需要在 public/index.html 中，写一个 id 为 app 的 div
createApp(App).mount('#app');
main.scss
* {
background-color: red;
}
安装依赖
npm i --save-dev vue vue-loader url-loader style-loader css-loader node-sass sass-loader
更改webpack.config.ts
import path from "path";//nodejs里面的基本包，用来处理路径
import { CleanWebpackPlugin } from "clean-webpack-plugin";
import HtmlWebpackPlugin from 'html-webpack-plugin';
import { VueLoaderPlugin } from "vue-loader"
const parentDir = path.resolve(process.cwd());
//我们先打个基本的包
export default {
mode: "development" as "development",
entry: "./src/main.ts",
output: {
path: path.join(parentDir, 'dist'),
filename: "bundle.js",
},
module: {
// 指定要加载的规则
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)$/i,
use: [
{
loader: 'url-loader',
options: {
limit: 8192,
},
},
],
},
{
test: /.ts$/, // 解析 ts
loader: "ts-loader",
options: {
// 上面一行不太重要，应该会按照默认路径寻找，下面一行必须要
// appendTsSuffixTo/appendTsxSuffixTo配置项的意思是说，从vue文件里面分离的script的ts,tsx（取决于<script lang="xxx"></script>）内容将会被加上ts或者tsx的后缀，然后交由ts-loader解析。
// 我在翻看了ts-loader上关于appendTsxSuffixTo的讨论发现，ts-loader貌似对文件后缀名称有很严格的限定，必须得是ts/tsx后缀，所以得在vue-loader extract <script>中内容后，给其加上ts/tsx的后缀名，这样ts-loader才会去处理这部分的内容。
// 在Vue项目中使用Typescript
configFile: path.resolve(process.cwd(), 'tsconfig.json'),
appendTsSuffixTo: [/.vue$/]
},
}
],
},
// 模块配置：让webpack了解哪些方法可以被当作模块引入
resolve: {
extensions: [
'.tsx',
'.ts',
'.mjs',
'.js',
'.jsx',
'.vue',
'.json']
},
plugins: [
new HtmlWebpackPlugin({
title: '你好，世界',
template: './public/index.html'
}),
new CleanWebpackPlugin(),
// make sure to include the plugin for the magic
new VueLoaderPlugin()
]
};
创建shims-vue.d.ts
/* eslint-disable */
declare module '*.vue' {
import type { DefineComponent } from 'vue'
const component: DefineComponent<{}, {}, any>
export default component
}
最终的package.json
{
"name": "create-my-vue-test",
"version": "1.0.0",
"main": "index.js",
"type": "module",
"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"dev": "esno ./config/dev.ts",
"build": "esno ./config/build.ts"
},
"keywords": [],
"author": "",
"license": "ISC",
"description": "",
"dependencies": {
"clean-webpack-plugin": "^4.0.0",
"css-loader": "^6.9.1",
"esno": "^4.0.0",

}
再次运行，基础搭建好了
