How to link angular 2 in node js?

Your project folder struction should like below

project/server [Node]

project/server.js is your express server

// Get our API routes
const api = require('./server/routes/api');

const app = express();

// Parsers for POST data
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

// Point static path to dist
app.use(express.static(path.join(__dirname, 'dist')));

// Set our api routes
app.use('/api', api);

// Catch all other routes and return the index file
app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, 'dist/index.html'));
});

project/src/index.html [angular code]

You can build angular code into dist using

ng build

This creates the dist folder with the angular 2 app built files. Now we can serve the app with express.

For run server use

node server.js

which create server
