Rollup构建TS项目

安装依赖

1.全局安装rollup npm install rollup-g

2.安装TypeScript npm install typescript -D

3.安装TypeScript 转换器 npm install rollup-plugin-typescript2 -D

4安装代码压缩插件 npm install rollup-plugin-terser -D

5 安装rollupweb服务 npm install rollup-plugin-serve -D

6 安装热更新 npm install rollup-plugin-livereload -D

7引入外部依赖 npm install rollup-plugin-node-resolve -D

8安装配置环境变量用来区分本地和生产 npm install cross-env -D

9替换环境变量给浏览器使用 npm install rollup-plugin-replace -D

webpack构建TS项目

安装依赖

安装webpack npm install webpack -D

webpack4以上需要 npm install webpack-cli -D

编译TS npm install ts-loader -D

TS环境 npm install typescript -D

热更新服务 npm install webpack-dev-server -D

HTML模板 npm install html-webpack-plugin -D

配置文件

const path = require('path')
const htmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {entry: "./src/index.ts",mode: "development",output: {path: path.resolve(__dirname, './dist'),filename: "index.js"},stats: "none",resolve: {extensions: ['.ts', '.js'],alias: {'@': path.resolve(__dirname, './src')}},module: {rules: [{test: /\.ts$/,use: "ts-loader"}]},devServer: {port: 1988,proxy: {}},plugins: [new htmlWebpackPlugin({template: "./public/index.html"})]

esbuild + swc 构建ts项目

本文正在参加「金石计划」

前端工具层出不穷，之前有常用的打包工具webpack，现在有了速度更快的vite。 vite的开发模式是基于esBuild编译的,打包又是基于rollup,启动项目是很快的。

esbuild为什么这么快

在esbuild的官方介绍中打包threejs 只需要0.37秒无限接近于亚索的Q技能冷却时间可以说是很快了。

esbuild是go语言编写的并且是多线程执行,性能是js的好几十倍，所以很快。

无需缓存即可实现基础打包
支持 ES6 跟 CommonJS 模块
支持ES 6 Tree Shaking
体积小
插件化
其他
内置支持编译 jsx

SWC

SWC则宣称其比Babel快20倍(四核情况下可以快70倍)

swc是用rust写的，所实现的功能跟babel一样，es6语法转es5，但是速度比babel更快，前端基建工具使用rust的是越来越多了，未来可能还会有一个替代postCss的
