dumi babel exapple (base father2)

babel 方式踩的坑

babel 方式是文件到文件的编译,不会做额外的处理

  • 不要在组件中使用 cssModules,否则,构建产物也会保持 cssModules 的引用方式(形如:import Styles from 'style/index.css
  • 需要生成 d.ts 文件,需要引入静态资源,看PR临时方案
  • 如果需要 umd 产物,不要像 antd 那样 css 和 js 分离开发,因为 umd 使用的是 rollup 打包,分离开发下 css 没有依赖关系,不会被打包

Introduction

  • base antd
  • babel
  • build esm、cjs、umd
  • support import assets: css、image、...
  • supprot d.ts
  • support unitTest(@testing-library/react)

方案

support import assets && supprot d.ts

为了支持 babel 方式下,引入静态资源,并生成 d.ts 声明文件,提了PR,但 father2 目前官方没时间处理,我这里进行了 hack 处理。

临时方案:umijs/father#227,以下不用看了


增加 npm 命令"hack": "node scripts/hack-depend.js",对 node_modules 下的依赖进行 hack 处理:

  • typings.d.ts 文件中声明非js/ts 模块:
declare module'*.css';declare module'*.less';declare module'*.png';declare module'*.jpg';declare module'*.gif';
  • package.json 添加脚本命令:
"scripts" : {"postinstall":"node scripts/hack-depend.js"}
  • scripts/hack-depend.js 脚本:
/** * 重写依赖模块(读取文件查找替换) */constfs=require('fs');constpath=require('path');constsep=path.posix.sep;consthacks=[{// https://github.com/umijs/father/pull/220 ,官方没时间处理 PR,这里进行 hack 处理name:'father-build',path:'../node_modules/father-build/lib/babel.js',hack:data=>{// console.log(data)returndata.replace(`    function getTsconfigCompilerOptions(path) {      const config = parseTsconfig(path);      return config ? config.compilerOptions : undefined;    }    function getTSConfig() {      const tsconfigPath = (0, _path.join)(cwd, 'tsconfig.json');      const templateTsconfigPath = (0, _path.join)(__dirname, '../template/tsconfig.json');      if ((0, _fs.existsSync)(tsconfigPath)) {        return getTsconfigCompilerOptions(tsconfigPath) || {};      }      if (rootPath && (0, _fs.existsSync)((0, _path.join)(rootPath, 'tsconfig.json'))) {        return getTsconfigCompilerOptions((0, _path.join)(rootPath, 'tsconfig.json')) || {};      }      return getTsconfigCompilerOptions(templateTsconfigPath) || {};    }`,`    function getTsconfigCompilerOptions(path) {      const config = parseTsconfig(path);      return config ? config.compilerOptions : undefined;    }    function getTsconfigInclude(path) {      const config = parseTsconfig(path);      const includesPath = config ? config.include || [] : [];      return includesPath;    }    function getTSConfig() {      const tsconfigPath = (0, _path.join)(cwd, 'tsconfig.json');      const templateTsconfigPath = (0, _path.join)(__dirname, '../template/tsconfig.json');      if ((0, _fs.existsSync)(tsconfigPath)) {        return getTsconfigCompilerOptions(tsconfigPath) || {};      }      if (rootPath && (0, _fs.existsSync)((0, _path.join)(rootPath, 'tsconfig.json'))) {        return getTsconfigCompilerOptions((0, _path.join)(rootPath, 'tsconfig.json')) || {};      }      return getTsconfigCompilerOptions(templateTsconfigPath) || {};    }    function getTSMatch() {      const tsconfigPath = join(cwd, 'tsconfig.json');      const templateTsconfigPath = join(__dirname, '../template/tsconfig.json');      if (existsSync(tsconfigPath)) {        return getTsconfigInclude(tsconfigPath) || [];      }      if (rootPath && existsSync(join(rootPath, 'tsconfig.json'))) {        return getTsconfigInclude(join(rootPath, 'tsconfig.json')) || [];      }      return getTsconfigInclude(templateTsconfigPath) || [];    }`,).replace(`&& !path.endsWith('.d.ts');`,`&& (path.endsWith('typings.d.ts') || path.endsWith('index.d.ts') || !path.endsWith('.d.ts'));`,).replace(`[(0, _path.join)(srcPath, '**/*'),`,`[(0, _path.join)(srcPath, '../typings.d.ts'),(0, _path.join)(srcPath, '../index.d.ts'),(0, _path.join)(srcPath, '../typings/index.d.ts'),(0, _path.join)(srcPath, '**/*'),`,);},},];construn=()=>{for(constitemofhacks){constfinalPath=path.resolve(__dirname,item.path.replace(/\//g,sep));fs.readFile(finalPath,'utf8',(err,data)=>{if(err){throwerr;}// console.log('=====data=====')// console.log(data.indexOf(`&& !path.endsWith('.d.ts');`))// console.log(typeof data)// console.log(String(data))// console.log('=====data=====')constfixed=item.hack(data);fixed&&fs.writeFile(finalPath,fixed,err=>{if(err){throwerr;}console.log('hack success');});});}};run();

发包后,在 umi 项目中使用 lean 组件库

在 tsx 中使用

importReactfrom'react';import{Foo,Button}from'lean';exportdefault()=>{return(<div><Footitle="demo"/><ButtonbtnType="primary">primary</Button></div>);};

Getting Started

Install dependencies,

$ npm i

Hack dependencies,

$ npm run hack

Start the dev server,

$ npm start

Build documentation,

$ npm run docs:build

Build library viafather-build,

$ npm run build

Test Components,

# test all components$ npm runtest
# test all components with coverage$ npm run test:coverage
# test one component Foo$ npx umi-test src/Foo/index.test.tsx
