Angular 16 SSR 抛出 TypeError：“instanceof”的右侧不是对象

Question

我只是想将我的 Angular 应用程序从版本 15 更新到 16。一切都适用于 Angular。即使它使角度通用构建也没有错误。但是当我尝试使用

npm run serve:ssr

服务时，它会抛出错误

类型错误：“instanceof”的右侧不是对象

最初我认为这可能是我的代码中的一些错误，但我删除了整个代码并仅保留具有简单标题的应用程序组件。它仍然抛出同样的错误。

服务器.ts

import { enableProdMode } from "@angular/core";
(global as any).WebSocket = require('ws');
(global as any).XMLHttpRequest = require('xhr2');
import 'zone.js/dist/zone-node';
const domino = require('domino');
const fs = require('fs');
const path = require('path');


import { ngExpressEngine } from '@nguniversal/express-engine';
import * as express from 'express';
import { join } from 'path';
import { existsSync } from 'fs';
const dotenv = require('dotenv');
dotenv.config();
const distFolder = join(process.cwd(), 'dist/project-name/browser');
const template = fs.readFileSync(path.join(distFolder, 'index.html')).toString();
const win = domino.createWindow(template.toString());
global['window'] = win;
global['document'] = win.document;
global['DOMTokenList'] = win.DOMTokenList;
global['Node'] = win.Node;
global['Text'] = win.Text;
global['HTMLElement'] = win.HTMLElement;
global['navigator'] = win.navigator;
global['getComputedStyle'] = win.getComputedStyle;

// (global as any).self = {fetch: require('node-fetch')};

// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();

import { AppServerModule } from './src/main.server';
import { APP_BASE_HREF } from '@angular/common';


// The Express app is exported so that it can be used by serverless Functions.
export function app(): express.Express {
  const server = express();
  const distFolder = join(process.cwd(), 'dist/project-name/browser');
  const indexHtml = existsSync(join(distFolder, 'index.original.html')) ? 'index.original.html' : 'index';

   // Our Universal express-engine (found @ https://github.com/angular/universal/tree/main/modules/express-engine)
   server.engine('html', ngExpressEngine({
    bootstrap: AppServerModule
  }));

  server.set('view engine', 'html');
  server.set('views', distFolder);

  // Example Express Rest API endpoints
  // server.get('/api/**', (req, res) => { });
  // Serve static files from /browser
  server.get('*.*', express.static(distFolder, {
    maxAge: '1y'
  }));

  // All regular routes use the Universal engine
  server.get('*', (req, res) => {
    res.render(indexHtml, { req, providers: [{ provide: APP_BASE_HREF, useValue: req.baseUrl }] });
  });

  return server;
}

function run(): void {
  const port = process.env.PORT || 8000;
  // Start up the Node server
  const server = app();
  server.get('/env', (req, res) => {
    res.json(process.env);
  })
  server.listen(port, () => {
    console.log(`Node Express server listening on https://localhost:${port}`);
  });
}

// Webpack will replace 'require' with '__webpack_require__'
// '__non_webpack_require__' is a proxy to Node 'require'
// The below code is to ensure that the server is run only when not requiring the bundle.
declare const __non_webpack_require__: NodeRequire;
const mainModule = __non_webpack_require__.main;
const moduleFilename = mainModule && mainModule.filename || '';
if (moduleFilename === __filename || moduleFilename.includes('iisnode')) {
  run();
}

export * from './src/main.server';

main.server.ts

import { enableProdMode } from '@angular/core';

import { environment } from './environments/environment';

if (environment.production) {
  enableProdMode();
}

export { AppServerModule } from './app/app.server.module';

main.ts

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

if ( environment.production )
{
    enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule)
.catch(err => console.error(err));

app.server.module.ts

import { NgModule } from '@angular/core';
import { ServerModule } from '@angular/platform-server';

import { AppModule } from './app.module';
import { AppComponent } from './app.component';

@NgModule({
  imports: [
    AppModule,
    ServerModule,
  ],
  bootstrap: [AppComponent],
})
export class AppServerModule {}

app.module.ts

import { NgModule, InjectionToken  } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ExtraOptions, PreloadAllModules, RouterModule } from '@angular/router';
import { AppComponent } from 'app/app.component';
import { AppRoutingModule } from './app-routing.module';



let APP_ID: InjectionToken<string>;
const routerConfig: ExtraOptions = {
    scrollPositionRestoration: 'enabled',
    preloadingStrategy       : PreloadAllModules
};

@NgModule({
    declarations: [
        AppComponent,
    ],
    imports: [
        BrowserModule,
        AppRoutingModule,
   
        
    ],
    exports : [
    ],
    bootstrap   : [
        AppComponent
    ],
    
    providers: [
        { provide: APP_ID, useValue: 'serverApp' },
    ]

})
export class AppModule
{
}

我有什么遗漏的吗？

Answer 1

我在多米诺骨牌临时分叉扩展

的帮助下解决了问题

1. 安装多米诺骨牌分机。

   npm install domino-ext

   。
2. 删除

   domino

   导入并将其替换为 `server.ts 文件中的

   domino-ext

   。

server.ts

const domino = require('domino');

替换为

const domino = require('domino-ext');

现在进行构建和服务，之后就可以正常工作了。
