I updated my Angular 8 project to Angular 9. I ran the command “npm run build: ssr && npm run serve: ssr”. It worked flawlessly and “browser” and “server” folders were created in the “dist” folder.

I uploaded these files to my server (Plesk panel). I set it to read server / main.js file with node.js.

It failed because it could not find “browser / index.html” in “dist” folder. I created a folder called “dist” and moved the “browser” folder into it.

Then it timed out, my project did not work. I run Node.js in development mode to see the error, but it says there is a timeout.

server.ts

import 'zone.js/dist/zone-node';

import { ngExpressEngine } from '@nguniversal/express-engine';
import * as express from 'express';
import { join } from 'path';

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

const domino = require('domino'); // kb
const fs = require('fs'); // kb
const template = fs.readFileSync('dist/browser/index.html').toString(); // kb
const win = domino.createWindow(template); // kb
global['window'] = win;
global['document'] = win.document;
global["branch"] = null;
global["object"] = win.object;
global['DOMTokenList'] = win.DOMTokenList;
global['Node'] = win.Node;
global['Text'] = win.Text;
global['HTMLElement'] = win.HTMLElement;
global['navigator'] = win.navigator;

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

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

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

  // Example Express Rest API endpoints
  // app.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() {
  const port = process.env.PORT || 4000;

  // Start up the Node server
  const server = app();
  server.listen(port, () => {
    console.log(`Node Express server listening on http://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();
}

  1. I doubt tsconfig.json file baseUrl is the issue. You may remove the same and try once in local then server.

  2. These are the steps that I got Angular 9 with .net core 3.1 all working using Angular Universal and NodeIIS.

    This can get you started https://medium.com/@MarkPieszak/angular-universal-server-side-rendering-deep-dive-dc442a6be7b7.

    Note my final project is not pre-rendered it is ssr meaning certain pages have parameters and will keep growing over time so I can’t pre-render (cache) certain pages it needs to be ssr.

    I created an angular app within VS .net core and added universal. Then after you can run ng serve make sure you can run the following on your angular 9 app.

    1. ng run YOURAPPNAME:server:production –bundleDependencies true
    2. npm run build:ssr
    3. npm run serve:ssr

    Note make sure your code will work for ssr

    Fix Angular JS code to work for SSR

    1. change all code for localstorage e.g. if
      (isPlatformBrowser(this.platformId)) { }
    2. Google global[‘window’],
      global[‘document’] and app.use(cors()); for server.ts as you will
      need to set these up too.

    Server stuff

    1. look at the solution here for c# .net core for getting cors working https://www.codeproject.com/Questions/5162494/Currently-I-am-working-on-angular-and-web-API-NET

    2. Follow steps above to remove — on both lines and I used published wizard straight to IIS from VS (it copies a folder in the root containing lots of Dlls etc, a ClientApp folder that contains dist and a node_modules) See publish does all the hard work for you. If your doing this manually you copy entire contents from debug…publish folder. I did not even have to mess around with the web.config file. Once it published and I setup domain to point to that folder in IIS.

    3. install nodeiis and run npm run serve:ssr which will process all requests for website and translate to ssr – best to use pm2 (npm i pm2)

    4. I added this to the VS net core SPA startup

           app.UseSpa(spa =>
          {
              spa.UseProxyToSpaDevelopmentServer("http://localhost:4000");
      
              spa.Options.SourcePath = "ClientApp";
      
              if (env.IsDevelopment())
              {
                  spa.UseAngularCliServer(npmScript: "start");
              }
          });
      

    When testing locally I can run ng serve and change localhost to 4200 and then when I run npm run serve:ssr I can change to 4000 and you can refresh you website and see how it renders differently

    Notes

    I wish they made it easier but after all these steps it works and the website loads instantly. When I look at the page title using view source its the index title but Google Webmasters has read the correct title on all pages.

    Alternative Solution

    There is a paid service called prerender.io I was going to use them costs about €9 a month and can implement easy https://github.com/dingyuliang/prerender-dotnet/wiki/Prerender-Middleware-for-ASP.NET-Core. I used it for an angularJS project and it works fine.

    Hope these steps helps someone as it took me ages to get this working

  3. -make sure in your "Document Root" to choose the browser folder not server.

    -in your server.ts REMOVE this if condition:

    if (moduleFilename === __filename || moduleFilename.includes('iisnode')) {
      run();
    }
    

    and replace it with just:

    run();
    

    then restart your node.js app again from the plesk GUI
