Answer 1

I found a way to add the static pre-rendering manually.

For those interested, all the steps to manually add the static pre-rendering to the ng add @nguniversal/express-engine:

1. ng add @nguniversal/express-engine --clientProject [your project name] to initialize the server-side app module, app.server.module.ts

2. Create the files prerender.ts and static.paths.ts at the root level of your project next to server.ts

3. Copy the content of https://github.com/angular/universal-starter/blob/master/prerender.ts in your prerender.ts file

4. Create your routes in your static.paths.ts following the example https://github.com/angular/universal-starter/blob/master/static.paths.ts

5. Add the prerender entry in your webpack.server.config.js:

   module.exports = {
     mode: 'none',
     entry: {
       server: './server.ts',
       prerender: './prerender.ts'
     },
   

6. Add the prerender scripts in your package.json:

   "scripts": {
       ...
       "build:prerender": "npm run build:client-and-server-bundles && npm run compile:server && npm run generate:prerender",
       "generate:prerender": "cd dist && node prerender",
       "serve:prerender": "cd dist/browser && http-server"
     }
   

7. Edit the line 17 of your prerender.ts by

   const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main');
   

8. Install the package http-server to serve the prerender build:

   npm install http-server --save-dev
   

9. You are now ready to go!

   npm run build:prerender && npm run serve:prerender
   
   
   Starting up http-server, serving ./
