1.课程大纲 #

1.1 Vite2+Vue3+Typescript 搭建开发环境 #

1.2 rollup和vite2插件系统和自定义插件 #

1.3 从零实现vite2 #

2.安装 vite #

2.1 vite 介绍 #

2.2 vite 安装 # 

pnpm install vite -D

3.启动 vite #

3.1 package.json # 

{
  "scripts": {
    "dev": "vite",
    "build": "vite build"
  }
}

3.2 vite.config.js # 

import { defineConfig } from "vite"
export default defineConfig({})

3.3 index.html #

index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Vite App</title>
  </head>

  <body>
    <div id="app"></div>
    <script type="module" src="/src/main.ts"></script>
  </body>
</html>

3.4 src\env.d.ts # 

/// <reference types="vite/client" />

3.5 src\main.ts #

src\main.ts

export function render() {
  document.getElementById("app")!.innerHTML = "main";
}
render();

if (import.meta.hot) {
  import.meta.hot.accept((updatedModule) => updatedModule.render());
}

3.6 tsconfig.json #

tsconfig.json

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "moduleResolution": "node",
    "strict": true,
    "jsx": "preserve",
    "sourceMap": true,
    "esModuleInterop": true,
    "lib": ["esnext", "dom", "es2018.promise"]
  },
  "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"]
}
参数 解释
target 用于指定编译之后的版本目标
module 生成的模块形式：none、commonjs、amd、system、umd、es6、es2015 或 esnext 只有 amd 和 system 能和 outFile 一起使用 target 为 es5 或更低时可用 es6 和 es2015
moduleResolution 选择模块解析策略，有 node 和 classic 两种类型 module-resolution
strict 是否启动所有类型检查
jsx react 模式会生成 React.createElement，在使用前不需要再进行转换操作了，输出文件的扩展名为.js
sourceMap 把 ts 文件编译成 js 文件的时候，同时生成对应的 sourceMap 文件
esModuleInterop 为导入内容创建命名空间,实现 CommonJS 和 ES 模块之间的互相访问
lib 编译时引入的 ES 功能库，包括：es5 、es6、es7、dom 等。如果未设置，则默认为： target 为 es5 时: ["dom", "es5", "scripthost"] target 为 es6 时: ["dom", "es6", "dom.iterable", "scripthost"]
include include 也可以指定要编译的路径列表，但是和 files 的区别在于，这里的路径可以是文件夹，也可以是文件
