• Add scully inside your angular app.
  ng add @scullyio/init
• do some route configuration in ./scully.<projectName>.config.ts file.

npm install -g inliner

npm init scully-inliner
cd scully-inliner
npm install express

• create server.js
  

var Inliner = require('inliner');
var fs = require('fs');
const express = require('express');
const app = express();
const port = 3000;
app.use(express.static('public'));
app.listen(port, () => {
  console.log(`listening on port ${port}!`);

  new Inliner(`http://localhost:${port}`, function (error, html) {
    // compressed and inlined HTML page

    fs.appendFile('result.html', html, function (err) {
      if (err) throw err;
      console.log('Combiled result Saved as result.html!');
    });
  });

});

• Make static site from angular build using scully. Angular build result itself is not a static site, so scully is there.
  ng build
npm run scully
• ./dist/static folder will contain the result. If you click index.html, you will see the page works exactly same as the angular app.
• copy those files inside the node server app's public folder.
• Run node server to get result.html
