4. Create an instance of the Express.js server:

index.tsx
const app = express();

2 lines

5. Define the routes using Express.js router:

index.tsx
const router = express.Router();

// Route 1
router.get('/route1', (req, res) => {
  res.send('Route 1');
});

// Route 2
router.get('/route2', (req, res) => {
  res.send('Route 2');
});

// Use the router
app.use('/api', router);

6. Define the Traefik middleware:

index.tsx
app.use('/api', createProxyMiddleware({
  target: 'http://your_backend_host',
  router: {
    // Define the Traefik path router rules
    '/route1': 'service1', // Route 1 should be redirected to 'service1'
    '/route2': 'service2', // Route 2 should be redirected to 'service2'
  },
}));

7. Start the Express.js server:

index.tsx
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
78 chars
4 lines

In the above example, the Express.js server is listening on port 3000. The routes /route1 and /route2 are defined using the Express.js router. The Traefik path router is configured using the createProxyMiddleware function. If a request matches the specified path, it will be redirected to the corresponding backend service based on the Traefik rules.

Please make sure to replace 'http://your_backend_host' with the actual backend server URL that you want Traefik to proxy the requests to. Also, adjust the Traefik path router rules and services ('service1' and 'service2') according to your setup.

Remember to configure Traefik to recognize the backend services ('service1' and 'service2') and redirect traffic based on the defined path rules.
