app中嵌套html中js修改,如何对于create-react-app修改为多页面支持-优快云博客

这次给大家带来如何对于create-react-app修改为多页面支持，对于create-react-app修改为多页面支持的注意事项有哪些，下面就是实战案例，一起来看一下。

修改dev流程

在已经通过create-react-app生成项目的基础下yarn run eject

yarn add globby用于查看html文件

修改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

修改config/webpack.config.dev.js

// 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：entryObj

// new HtmlWebpackPlugin({

// inject: true,

// chunks: ["index"],

// template: paths.appPublic + '/index.html',

// }),

...htmlPluginsAray,

修改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}`

};

});

rewrites: htmlPluginsAray

以上就是dev模式下的修改了，yarn start一下试试。

修改product流程

修改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

})

});

entry: entryObj,

...htmlPluginsAray,

增加复制模块(yarn add cpy)

修改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,

// });

}

以上修改后测试下yarn build

查看下html对应生成对不对，正常是OK的。

增加功能

sass支持(此参考create-react-app的文档，注意不要直接复制文档里面的"start": "react-scripts start", "build": "react-scripts build",因为我们前面已经yarn eject,所以这样用的话是有问题的可以自行体验一下)// 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",

html引入模块yarn add html-loader
