If you are using angular need to access DOM with SSR, then use domino package.
Domino provide support for the DOM API and also CSS for querySelector(), querySelectorAll(), and matches().
Install domino from your terminal.

ng add @nguniversal/express-engine
Edit the server.ts file and add the following lines. For configuring it create a "document" object and "window" as global.
const domino = require('domino');
const fs = require('fs');
const path = require('path');
// Use the browser index.html as template for the mock window
const template = fs
.readFileSync(path.join(join(process.cwd(), 'dist/yourprojectname/browser'), 'index.html'))
.toString();
// Shim for the global window and document objects.
const window = domino.createWindow(template);
global['window'] = window;
global['document'] = window.document;
If you to copy and paste, please change the project name.
