我按照以下步骤在下一个 js 中实现了模块联合。
- 在存储库 cm-insurance-web 中的 src/node/components 文件夹中创建一个组件 Insurance_Detail.tsx，该组件将被公开。下面是 next.config.js 文件。
const assetPrefix = '/jobs-assets';
const nextConfig = {
assetPrefix,
env: {
assetPrefix
},
experimental: {
images: {
unoptimized: true
}
},
reactStrictMode: true,
webpack5: true,
srcDir: 'src/node/',
//distDir: 'build',
webpack: (config, options) => { // webpack configurations
config.plugins.push(
new options.webpack.container.ModuleFederationPlugin({
name:"InsuranceA",
filename: "static/chunks/pages/cm_insurance_web.js", // remote file name which will used later
remoteType: "var",
exposes: { // expose all component here.
**"./InsuranceDetail": "./components/Insurance_Details.tsx"**
},
shared: [
{
react: {
eager: true,
singleton: true,
requiredVersion: false,
}
},
{
"react-dom": {
eager: true,
singleton: true,
requiredVersion: false,
}
},
]
})
)
config.cache = false;
config.output.publicPath = 'http://localhost:3000/_next/';
return config
}
}
module.exports = nextConfig
当我们使用命令 npm run build 构建 repo cm-insurance-web 时，我们可以看到在 src/node/.next/static/chunks/pages/cm_insurance_web.js 中创建了 javascript 文件。这个项目 repo 在本地主机的 3000 端口上运行。
现在需要在其他存储库中使用此 javascript，比如 cm-job-board-web。让我们创建消费者应用程序。下面是它的 next.config.js 文件
/** @type {import('next').NextConfig} */
const assetPrefix = '/jobs-assets';
const path = require('path');
const nextConfig = {
assetPrefix,
env: {
assetPrefix
},
basePath: '/search-jobs',
experimental: {
images: {
unoptimized: true
}
},
reactStrictMode: true,
srcDir: 'src/node/',
webpack: (config, options) => {
config.plugins.push(
new options.webpack.container.ModuleFederationPlugin({
name:"jobboardWeb",
filename: "static/chunks/cm_job_board_web.js",
remoteType: "var",
remotes: {
InsuranceA: JSON.stringify('InsuranceA@http://localhost:3000/jobs-assets/_next/static/chunks/pages/cm_insurance_web.js')
},exposes: {},
shared: [
{
react: {
eager: true,
singleton: true,
requiredVersion: false,
}
},
{
"react-dom": {
eager: true,
singleton: true,
requiredVersion: false,
}
},
]
})
)
config.cache = false;
return config
},
webpack5: true
}
module.exports = nextConfig
- 在consumer app的_app.tsx文件中添加script标签如下:
import { AppProps } from "next/app";
import "bootstrap/dist/css/bootstrap.css";
import "../styles/globals.scss";
import Layout from "../components/layout";
import { persistor, store } from "../store/store";
import { Provider } from "react-redux";
import { PersistGate } from "redux-persist/integration/react";
import Authentication from "../config/auth.gaurd";
import Head from "next/head";
import React from "react";
import Script from "next/script";
function MyApp({ Component, pageProps }: AppProps) {
return (
<Layout>
<>
<Script src="http://localhost:3000/jobs-assets/_next/static/chunks/pages/cm_insurance_web.js" />
<Head>
<link rel="preconnect" href="https://fonts.googleapis.com"/>
<link rel="preconnect" href="https://fonts.gstatic.com"/>
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@100;200;300;400;500;600;700&display=swap"/>
<link rel="shortcut icon" href="/favicon2.ico"/>
<title>Jobboard Search</title>
</Head>
<Script id="gtm-script" strategy="afterInteractive">
{`(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-TKJH8RR');`
}
</Script>
<Provider store={store}>
<PersistGate loading={null} persistor={persistor}>
<Authentication>
<noscript dangerouslySetInnerHTML={{ __html:
`<iframe src="https://www.googletagmanager.com/ns.html?id=GTM-TKJH8RR"
height="0" width="0" style="display:none;visibility:hidden"></iframe>
`}}>
</noscript>
<Component {...pageProps} />
</Authentication>
</PersistGate>
</Provider>
</>
</Layout>
);
}
export default MyApp;
- 让我们将该模块导入 index.tsx 文件并使用它。
import {NextPage} from "next";
import React, {lazy, Suspense, useState} from "react";
import dynamic from 'next/dynamic'
const InsuranceDetail2 = dynamic(() => import(('InsuranceA/InsuranceDetail')), {
ssr: false
}) as NextPage;
const Insurance: NextPage = ({}: any) => {
return (
<InsuranceDetail2 />
)
}
export default Insurance
完成上述步骤后，我能够看到远程 js 文件正在浏览器的网络选项卡中加载，但远程组件未呈现并出现空白页面。

最佳答案
安装 nextjs-mf ⚠️ 注意:要使应用程序使用 Module Federation 功能，您需要访问 https://app.privjs.com/package?pkg=@module-federation/nextjs-mf[[nextjs-ssr^]目前需要付费许可的插件!
要安装该工具，我们需要使用 npm 登录 [PrivJs}(https://privjs.com/^)，为此，请运行以下命令:
npm 登录 --registry https://r.privjs.com
完成此操作后，包含您的凭据的文件将保存在 ~/.npmrc 中。现在您可以使用以下命令安装 nextjs-mf:
npm install @module-federation/nextjs-mf --registry https://r.privjs.com
所以模块联合是下一个js中的付费模块，在付费模块的帮助下，我能够实现它。
- 保险模块的next.config.js。
/** @type {import('next').NextConfig} */
const NextFederationPlugin = require('@module-federation/nextjs-mf');
const assetPrefix = '/jobs-assets';
const nextConfig = {
assetPrefix,
env: {
assetPrefix
},
reactStrictMode: true,
webpack5: true,
srcDir: 'src/node/',
//distDir: 'build',
webpack: (config, options) => { // webpack configurations
if (!options.isServer) {
config.plugins.push(
new NextFederationPlugin({
name: "insurancea",
filename: "static/chunks/pages/cm_insurance_web.js", // remote file name which will used later
exposes: { // expose all component here.
"./insurancedetail": "./components/Insurance_Details.tsx"
},
shared:
{
react: {
singleton: true,
requiredVersion: false,
}
}
}),
);
}
return config
}
};
module.exports = nextConfig
- 在 package.json 中添加模块联合的依赖。
"dependencies": {
"@module-federation/nextjs-mf": "^5.9.2",
}
- 在同一保险模块的 _app.tsx 文件中添加导入。
import '@module-federation/nextjs-mf/src/include-defaults';
这就是暴露组件
- 现在在 next.config.js 中为远程组件(消费者应用程序 - cm-job-board-web)更新它
/** @type {import('next').NextConfig} */
const NextFederationPlugin = require('@module-federation/nextjs-mf');
const assetPrefix = '/jobs-assets';
const path = require('path');
const nextConfig = {
assetPrefix,
env: {
assetPrefix
},
basePath: '/search-jobs',
reactStrictMode: true,
srcDir: 'src/node/',
webpack: (config, options) => {
if (!options.isServer) {
config.plugins.push(
new NextFederationPlugin({
name: "jobboardWeb",
filename: "static/chunks/cm_job_board_web.js",
remotes: {
// cm_insurance_web: options.isServer ? 'http://localhost:3000/jobs-assets/_next/static/chunks/cm_insurance_web.js' : 'fe1'
insurancea: 'insurancea@http://localhost:3000/jobs-assets/_next/static/chunks/pages/cm_insurance_web.js'
}, exposes: {},
shared: {}
}),
);
}
return config
},
webpack5: true
};
module.exports = nextConfig
- 在消费者应用程序的 package.json 中添加模块联合的依赖。
"dependencies": {
"@module-federation/nextjs-mf": "^5.9.2",
}
- 在消费者应用程序的 _app.tsx 文件中添加导入。
import '@module-federation/nextjs-mf/src/include-defaults';
- 最后将该模块导入 index.tsx 文件并在消费者应用程序中使用它。
import { Suspense } from 'react'
import React from 'react'
import dynamic from 'next/dynamic'
const DynamicComponent4 = dynamic(
() => import('insurancea/insurancedetail'),
{ loading: () => <p>Loading caused by client page transition ...</p>, ssr: false }
)
export default function Insurance() {
return (
<div>
<DynamicComponent4 />
</div>
)
}
就是这样。
关于next.js - 模块联合或微前端在 Next js 版本 12.2.0 中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/73986638/
