1. eject create-react-app
$ npm i yarn -g
$ yarn create react-app my-app
$ yarn eject
$ rm -rf node_modules\
$ yarn
2. 查看目录
| .gitignore
| package.json
| README.md
| yarn.lock
|
+---config #webpack 配置
| | env.js
| | paths.js
| | webpack.config.js
| | webpackDevServer.config.js
| |
| \---jest
| cssTransform.js
| fileTransform.js
|
+---public # 静态文件
| favicon.ico
| index.html
| manifest.json
|
+---scripts # 脚本
| build.js
| start.js
| test.js
|
\---src # 项目文件
App.css
App.js
App.test.js
index.css
index.js # webpack entry

serviceWorker.js
3. 修改 /config/
3.1
<mark>+</mark>： 表示添加代码；
<mark>-</mark>： 表示删除代码；
// /config/paths.js // 添加以下代码
+ const globby = require('globby');
// 获取所有入口js
+ const entriesPath = globby.sync([resolveApp('src') + '/*/index.js']).map(filePath => {
let tmp = filePath.split('/');
let name = tmp[tmp.length - 2];
return {path: filePath, name}
});
module.exports = {
- appIndexJs: resolveModule(resolveApp, 'src/index')
...
+ entriesPath,
}
// /config/webpackDevServer.config.js
+ const paths = require('./paths');
+ const files = paths.entriesPath;
+ const rewrites = files.map(({name, path}) => {
return {
from: new RegExp(`^\/${name}`),
to: `/${name}.html`
};
});
modelue.exports = function (proxy, allowedHost) {
return {
...
contentBase: paths.appPublic,
...
+ rewrites,
}
}
// /config/webpack.config.js
+ const paths = require('./paths');
module.exports = function (webpackEnv) {
// 获取 entry
+ function getEntries(){
const entries = {};
const files = paths.entriesPath;
// console.log(117, files)
files.forEach(({name, path}) => {
entries[name] = [
isEnvDevelopment && require.resolve('react-dev-utils/webpackHotDevClient'),
path,
].filter(Boolean);
});
return entries;
}
+ const entries = getEntries()
+ const htmlPlugin = Object.keys(entries).map(name => {
return new HtmlWebpackPlugin(Object.assign({}, {
inject: true,
template: paths.appHtml,
chunks: [name, 0], // 只会插入名字中带 "0" 或者 带 name 的js 问题
filename: `${name}.html`,
title: `${name} html`,
}, isEnvProduction
? {
minify: {
removeComments: true,
collapseWhitespace: true,
removeRedundantAttributes: true,
useShortDoctype: true,
removeEmptyAttributes: true,
removeStyleLinkTypeAttributes: true,
keepClosingSlash: true,
minifyJS: true,
minifyCSS: true,
minifyURLs: true
}
}
: undefined));
});
}
return {
...
- entry: [
isEnvDevelopment &&
require.resolve('react-dev-utils/webpackHotDevClient'),
paths.appIndexJs,
].filter(Boolean),
+ entry:entries,
output: {
...
- filename: isEnvProduction
? 'static/js/[name].[contenthash:8].js'
: isEnvDevelopment && 'static/js/bundle.js',
+ filename: isEnvProduction
? 'static/js/[name].[contenthash:8].js'
: isEnvDevelopment && 'static/js/[name].bundle.js',
...
}
...
plugins: [
- new HtmlWebpackPlugin(
Object.assign(
{},
{
inject: true,
template: paths.appHtml,
},
isEnvProduction
? {
minify: {
removeComments: true,
collapseWhitespace: true,
removeRedundantAttributes: true,
useShortDoctype: true,
removeEmptyAttributes: true,
removeStyleLinkTypeAttributes: true,
keepClosingSlash: true,
minifyJS: true,
minifyCSS: true,
minifyURLs: true,
},
}
: undefined
)
),
+ ...htmlPlugin,
]
}
// /scripts/start.js
// /scripts/build.js
// /scripts/test.js
+ const path = require("path")
- if (!checkRequiredFiles([paths.appHtml, paths.appIndexJs])) {
process.exit(1);
}
+ paths.entriesPath.forEach(({path, name}) => {
if (!checkRequiredFiles([paths.appHtml, path])) {
process.exit(1);
}
})
4. 修改目录
| .gitignore #
| package.json
| README.md
| yarn.lock
|
+---config #webpack 相关配置
| | env.js
| | paths.js
| | webpack.config.js
| | webpackDevServer.config.js
| |
| \---jest
| cssTransform.js
| fileTransform.js
|
+---public # 静态文件
| favicon.ico
| index.html
| manifest.json
|
+---scripts # 脚本
| build.js
| start.js
| test.js
|
\---src # 项目文件
| logo.svg
| serviceWorker.js
| App.css # 删除
| App.js # 删除
| App.test.js # 删除
| index.css # 删除
| index.js # 删除
| logo.svg
| serviceWorker.js
|
+ +---h5 # 添加
| | index.js
| |
| +---container
| | \---pcDemo
| | index.css
| | index.js
| |
| +---reducer
| | index.js
| |
| \---store
| index.js
|
+ \---pc # 添加
| index.js
|
+---container
| \---pcDemo
| index.css
| index.js
|
+---reducer
| index.js
|
\---store
index.js
5. 至此，多入口已经修改完毕
6. 对 index.html 做处理
$ yarn add handlebars-loader --save
// /config/webpack.config.js
module.exports = function (webpackEnv) {
...
return {
...
module: {
rules: [
+ {
test: /.hbs$/,
loader: require.resolve('handlebars-loader')
},
]
}
}
}
