It works — your Express app is live

express@4.21.2   node v20.11.1   HTTP 200 OK

The HTTP server bound to port 3000 and answered this request through the default index handler. Edit routes/index.js to replace this placeholder with your application logic.

Default route

const express = require('express');
const morgan  = require('morgan');
const app     = express();

app.use(morgan('combined'));
app.use(express.json({ limit: '1mb' }));

app.get('/', (req, res) => {
  res.type('text/html').send('Hello from node-runtime-09');
});

app.get('/healthz', (req, res) => res.json({ status: 'ok' }));

app.use((err, req, res, next) => {
  console.error(err.stack);
  res.status(500).send('internal');
});

app.listen(3000, '0.0.0.0', () => console.log('ready on :3000'));

Mounted middlewares

What to do next

• Mount additional routers in app.use('/api', apiRouter)
• Add middleware for JSON body parsing, logging and CORS
• Configure a reverse proxy in front of this process (nginx, Caddy)
• Set app.set('trust proxy', 1) if behind a load balancer
• Tune the keep-alive timeout to match your upstream proxy

If you intended to deploy a different application, verify the working directory of the supervised process and the value of NODE_ENV. Logs are available via pm2 logs or journalctl -u app.service.
