How to modify create-react-app to support multiple pages

This time I will show you how to modify create-react-app to support multi-page, and what are the precautions for modifying create-react-app to support multi-page. The following is a practical case. Let’s take a look.

Modify the dev process

Based on the project that has been generated through create-react-app

yarn run eject

yarn add globby Used to view html files

Modify config/paths.js

//遍历public下目录下的html文件生成arry
const globby = require('globby');
const htmlArray = globby.sync([path.join(resolveApp('public'), '/*.html')]);
//module.exports 里面增加
htmlArray

Modify config/webpack.config.dev.js

<!--增加配置-->
// 遍历html
const entryObj = {};
const htmlPluginsAray = paths.htmlArray.map((v)=> {
 const fileParse = path.parse(v);
 
 entryObj[fileParse.name] = [
  require.resolve('./polyfills'),
  require.resolve('react-dev-utils/webpackHotDevClient'),
  `${paths.appSrc}/${fileParse.name}.js`,,
 ]
 return new HtmlWebpackPlugin({
  inject: true,
  chunks:[fileParse.name],
  template: `${paths.appPublic}/${fileParse.base}`,
  filename: fileParse.base
 })
});
<!--entry 替换为entryObj-->
entry：entryObj
<!--替换htmlplugin内容-->
// new HtmlWebpackPlugin({
//  inject: true,
//  chunks: ["index"],
//  template: paths.appPublic + '/index.html',
// }),
...htmlPluginsAray,

Modify config/webpackDevServer.config.js

// 增加
const path = require('path');
const htmlPluginsAray = paths.htmlArray.map((v)=> {
 const fileParse = path.parse(v);
 return {
  from: new RegExp(`^\/${fileParse.base}`), to: `/build/${fileParse.base}`
 };
});
<!--historyApiFallback 增加 rewrites-->
rewrites: htmlPluginsAray

The above are the modifications in dev mode, try yarn start.

Modify product process

Modify config/

//增加
// 遍历html
const entryObj = {};
const htmlPluginsAray = paths.htmlArray.map((v)=> {
 const fileParse = path.parse(v);
 
 entryObj[fileParse.name] = [
  require.resolve('./polyfills'),
  `${paths.appSrc}/${fileParse.name}.js`,
 ];
 console.log(v);
 return new HtmlWebpackPlugin({
  inject: true,
  chunks:[fileParse.name],
  template: `${paths.appPublic}/${fileParse.base}`,
  filename: fileParse.base
 })
});
<!--修改entry-->
 entry: entryObj,
<!--替换 new HtmlWebpackPlugin 这个值-->
...htmlPluginsAray,

Add copy module (

yarn add cpy)

Modify scripts/build.js

 // function copyPublicFolder () 替换
// 原来的方法是复制public下所有的内容，因为增加了多html 所以不再直接复制过去(直接复制会覆盖html)
const copyPublicFolder = async() => {
 await cpy([`${paths.appPublic}/*.*`, `!${paths.appPublic}/*.html`], paths.appBuild);
 console.log('copy success!');
 // fs.copySync(paths.appPublic, paths.appBuild, {
 //  dereference: true,
 //  filter: file => file !== paths.appHtml,
 // });
}

After the above modification, test it

yarn build

Check whether the html corresponding generation is correct, it is normal.

Added function

sass support (refer to the document of create-react-app, be careful not to directly copy the "start" in the document: "react-scripts start" , "build": "react-scripts build", because we have yarn eject before, so there are problems if you use it like this. You can try it yourself)

// 增加模块
yarn add node-sass-chokidar npm-run-all
// package.json删除配置
"start": "node scripts/start.js",
"build": "node scripts/build.js",
// package.json里面增加scripts
"build-css": "node-sass-chokidar src/scss -o src/css",
"watch-css": "npm run build-css && node-sass-chokidar src/scss -o src/css --watch --recursive",
"start-js": "node scripts/start.js",
"start": "npm-run-all -p watch-css start-js",
"build-js": "node scripts/build.js",
"build": "npm-run-all build-css build-js",

htmlIntroducing modules

yarn add html-loader
<!--index.html-->
<%= require(&#39;html-loader!./partials/header.html&#39;) %>

html You can write img to support packaging into build. If you don't write it, it will not be packaged. Unless you cancel the hash and other configurations after require

<img src="<%= require(&#39;../src/imgs/phone.png&#39;) %>" alt="">

in js, this will not be recorded.
