}
我对 server.ts 文件进行了以下更改
添加到server.ts
import { createWindow } from 'domino';
// Polyfills
(global as any).window = win;
(global as any).document = win.document;
(global as any).navigator = win.navigator;
我还创建了一个 window-ref.service.ts 并将其传递到提供程序部分的 app.module.ts 中。
import { Injectable } from '@angular/core';
function _window(): any {
return window;
}
@Injectable({
providedIn: 'root',
})
export class WindowRefService {
get nativeWindow(): any {
return _window();
}
constructor() {}
}

您可能知道，使用 SSR，您的 JS 不是在浏览器环境中运行，而是在 NodeJS 上运行。节点运行时中不存在像
windowself因此，您需要放弃使用这些变量，并可能删除使用此类代码的库。
如果您需要访问nodejs和浏览器运行时中都存在的全局对象，您可以使用
