I have just created a simple Angular SSR application using Angular CLI: 18.2.12. I am not using ngExpressEngine, but I am using @angular/platform-server The application works fine with npm run build:ssr and npm run serve:ssr. However, when I use built-in browser objects like localStorage, sessionStorage, window, location, document, or isBrowser, I encounter errors. I understand that these objects are not accessible on the server. In my application, these variables (e.g., localStorage and window) are used extensively. I tried using libraries like Domino and JSDOM, but they didn’t work properly. I also referred to this post: Angular CLI - How to use window, document, or location in environment.ts. Still, I couldn’t find a better solution. Here is my server.ts file: import 'zone.js/node'; import { renderModule } from '@angular/platform-server'; import express from 'express'; import { join } from 'path'; import AppServerModule from './src/main.server'; // import { readFileSync } from 'fs'; // import { JSDOM } from 'jsdom' const app = express(); const PORT = process.env['PORT'] || 4000; const DIST_FOLDER = join(process.cwd(), 'dist/angular-ssr-project/browser'); // Serve static files app.use(express.static(join(DIST_FOLDER, 'browser'), { maxAge: '1y', index: false })); // Serve SSR page app.get('*', (req, res) => { renderModule(AppServerModule, { document: '<app-root></app-root>', url: req.url }).then(html => { res.send(html); }).catch(err => { console.error('SSR Rendering Error:', err); res.status(500).send('Error during SSR rendering'); }); }); // Start the server app.listen(PORT, () => { console.log(`Node Express server listening on http://localhost:${PORT}`); }); // const dom = new JSDOM('<!doctype html><html><body></body></html>'); // global['window'] = dom.window; // global['document'] = dom.window.document; // ... // ... // const template = readFileSync(join(DIST_FOLDER, 'index.html')).toString(); // const win = createWindow(template); // global['window'] = win as any; // global['document'] = win.document; // global['navigator'] = win.navigator; // ... // ...
