项目依赖

脚本

// index.jsimport './src/App.jsx'// App.jsximport React from 'react'import { render } from 'react-dom'import Test from './components/Test/index.jsx'render(<Test />, document.getElementById("app"))// Testimport React from 'react'import Child from '../Child/index.jsx'export default class Test extends React.Component {  state = {    msg: 'hello, world'  }  render() {    const { msg } = this.state    return <Child msg={msg}/>  }}// Childimport React from 'react'const Child = (props) => <div className="color">{props.msg}</div>export default Child

css

.color {  color: red;}

构建脚本

const path = require('path')const gulp = require('gulp')const babelify = require('babelify')const browserify = require('browserify')  // 插件,    // 转成stream流，gulp系const source = require('vinyl-source-stream')    // 转成二进制流，gulp系const buffer = require('vinyl-buffer')const { series, parallel } = require('gulp')const del = require('del')const concat = require('gulp-concat')const resolveDir = (dir) => path.resolve(__dirname, dir)const _path = {  main_js: resolveDir('./index.js'),  css: ['./src/components/**/*.css']}const clean = (done) => {  del(resolveDir('./dist'))  done()}const _css = () => {  return gulp.src(_path.css)    .pipe(concat('app.css'))    .pipe(gulp.dest('./dist/css'))}const _script = () => {  return browserify({      entries: _path.main_js,      transform: [babelify.configure({        presets: ['@babel/preset-env', '@babel/preset-react'],        plugins: [          '@babel/plugin-transform-runtime',           ["@babel/plugin-proposal-decorators", { "legacy": true }],           ["@babel/plugin-proposal-class-properties", { "loose": true }]        ]      })]    })    .bundle()    .pipe(source('app.js'))    // .pipe(buffer())    .pipe(gulp.dest('./dist/js'))}module.exports.build = series(clean, parallel(_script, _css))

在index.html中引入打包之后的js和css

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <meta name="viewport" content="width=device-width, initial-scale=1.0">  <title>Document</title>  <link rel="stylesheet" href="./css/app.css"></head><body>  <div id="app"></div>  <script src="./js/app.js"></script></body></html>

效果：
