项目搭建
模仿vue-next，monorepo分包。
Monorepo 是一种项目代码管理方式，指单个仓库中管理多个项目，有助于简化代码共享、版本控制、构建和部署等方面的复杂性，并提供更好的可重用性和协作性。Monorepo 提倡了开放、透明、共享的组织文化，这种方法已经被很多大型公司广泛使用，如 Google、Facebook 和 Microsoft 等。
全部用yarn命令或者pnpm，npm好像不行，反正我这是报错。

rollup 配置
__dirname好用，所以文件是cjs文件，如果改成msj，你需要查查攻略，我看了一眼，太麻烦了，就算了。换成了commonjs
// 通过rollup进行打包
// import resolvePlugin from '@rollup/plugin-node-resolve' //解析第三方插件
// import ts from 'rollup-plugin-typescript2'; //ts
// import json from '@rollup/plugin-json';//json
// import path from 'path'; //处理路径
const resolvePlugin = require('@rollup/plugin-node-resolve'); //解析第三方插件
const ts = require('rollup-plugin-typescript2'); //ts
const json = require('@rollup/plugin-json');//json
const path = require('path'); //处理路径
// 获取文件路径
let packagesDir = path.resolve(__dirname, 'packages'); //获取packages路径
//获取需要打包的包
let packageDir = path.resolve(packagesDir, process.env.TARGET);
//打包获取到每个包的项目配置
let resolve = p => path.resolve(packageDir, p);//获取每个包的路径
let pkg = require(resolve('package.json'));
let name = path.basename(packageDir);//获取包名
//创建映射表
const outputOpions = {
"esm-bundler": {
file: resolve(`dist/${name}.esm-bundler.js`),
format: 'es'
},
"cjs": {
file: resolve(`dist/${name}.cjs.js`),
format: 'cjs'
},
"global": {
file: resolve(`dist/${name}.global.js`),
format: 'iife'
}
}
//获取打包的包
const options = pkg.buildOptions;
function createConfig (format, output) {
//进行打包
output.name = options.name;//打包的包名
output.sourcemap = true;//是否生成sourcemap
return {
input: resolve(`src/index.ts`),//输入文件
output,
plugins: [
ts({
tsconfig: path.resolve(__dirname, 'tsconfig.json')
}),
json(),
resolvePlugin(),
]
}
}
//rollup选哟导出一个配置
module.exports =
options.formats.map(format => createConfig(format, outputOpions[format]))
//打包配置文件const createConfig = (format, options) => ({//打包配置文件，包括输入文件、
脚本文件
- 在script下创建build.mjs execa不支持commonjs导入，最新版的都有这个问题，然后就改成mjs文件
import { execa } from 'execa';
//打包 monerepo
// 1. 获取打包文件
// const fs = require('fs')
import fs from 'fs';
// import { execa } from 'execa'
const dirs = fs.readdirSync('packages').filter(p => {
if (!fs.statSync(`packages/${p}`).isDirectory()) return false; //打包文件夹，过滤掉packages下的文件
return true;
})
// 2. 打包 并行 promisAll
runParaller(dirs, build).then(() => { //promise
console.log('打包完成');
})
async function runParaller (dirs, itemfn) {
let result = []
for (let item of dirs) {
result.push(itemfn(item));
}
return Promise.all(result); //存放打包的promise
}
async function build (target) {
console.log(target);
// -c 执行rollup配置，环境变量-env
await execa('rollup', ['-c', '--environment', `TARGET:${target}`],{stdio: 'inherit'}) //子进程输出父包
}
- 创建dev.js
import { execa } from 'execa';
async function build (target) {
// -c 执行rollup配置，环境变量-env
await execa('rollup', ['-cw', '--environment', `TARGET:${target}`],{stdio: 'inherit'}) //子进程输出父包
}
build('reactivity')
- 根package.json添加脚本
"build": "node scripts/build.mjs",
"dev": "node scripts/dev.mjs"
