simple proxy service in nodejs

As the title advises, I'm trying to create a simple proxy service in nodejs.

const express = require('express');
const proxy = require('http-proxy-middleware');

const app = express();

const auth = proxy({
  target: 'http://localhost:4200',
  ws: true
});

const game = proxy({
  target: 'http://localhost:4201',
  ws: true
});

app.use('/', auth);

app.use('/game', game);

app.listen(80, () => {
  console.log('Proxy listening on port 80');
});

However, only the auth route is being mapped correctly to / The game is not working at all and I'm wondering why exactly?

Is this approach correct or are there any other ways to achieve the expected route mapping?

Try this, it is working fine: Path rewrite is used for removing the /game part. If you will not use path rewrite then it will hit http://localhost:4201/game (with base path). 

    const express = require('express');
    const proxy = require('http-proxy-middleware');

    const app = express();

    const auth = proxy({
      target: 'http://localhost:4200',
      ws: true
    });

    const game = proxy({
      target: 'http://localhost:4201',
      pathRewrite: {
        '^/game': '' // remove base path
      },
      ws: true
    });
    app.use('/game', game);
    app.use('/', auth); // route '/' should be in last

    app.listen(8080, () => {
      console.log('Proxy listening on port 80');
    });
