实验环境：

• qiankun: ^2.10.16
• next: 14.1.0
• react: ^18.2.0

根据官方手册快速上手教程(链接)

构建主程序实验代码：

• qiankun部分：

// file: micro-base/plugins/qiankun/index.ts

import type { AppMetadata } from 'qiankun';
import { registerMicroApps, start } from "qiankun";
import { Microconfig } from "@/plugins/qiankun/microAppsConfig"

export const QianKunStart = function (){
    registerMicroApps(Microconfig);
    start();
}

export default QianKunStart;

• 页面引用

// file: micro-base/app/page.tsx

import { useEffect } from "react";
import { QianKunStart } from "@/plugins/qiankun"

export default function Home() {
    useEffect(() => {
        console.log('QianKunStart...')
        QianKunStart();
    }, [])

    return (
        <>
            <header>header</header>
            <main>
                <ul>
                    <li><a href="/">首页</a></li>
                    <li><a href="/">子应用</a></li>
                </ul>
                <div id={'mainView'}></div>
            </main>
        </>
    );
}

运行后出现如下错误提示：

经过几番调试寻找，目前有个来至qiankun issues的解决方案：

• 【在nextjs+react中使用qiankun当作主应用时报错 ReferenceError: window is not defined】

基于这个方案，调整下上面实验代码：

• qiankun部分：

// file: micro-base/plugins/qiankun/index.ts

import type { AppMetadata } from 'qiankun';
// import { registerMicroApps, start } from "qiankun"; // 这段删掉
import { Microconfig } from "@/plugins/qiankun/microAppsConfig"

export const QianKunStart = function (){
    // 新增
    if(typeof window !== undefined){
        // 新增
        const { registerMicroApps,start, addGlobalUncaughtErrorHandler } = require('qiankun');

        registerMicroApps(Microconfig, lifeCycles);
        start();
    }
}

export default QianKunStart;

实测可行！
