• Ensure you define your port as follows: const port = process.env.PORT || 8080; in your code. – Aslesha Kantamsetti Commented Nov 20, 2024 at 8:30

I created simple Nodejs app with PM2 deployed to the Azure App service.

Even I got the same error when hardcoded the port value in the server.js and ecosystem.config.js.

Azure App Service expects the application to listen on the port specified by the PORT environment variable.

I define the port value as below

const port = process.env.PORT || 8080;

server.js:

const express = require('express');
const app = express();
const port = process.env.PORT || 8080;
app.get('/', (req, res) => {
    res.send('Hello, World! Application is running.');
});
app.listen(port, () => {
    console.log(`Server is listening on port ${port}`);
});

ecosystem.config.js:

module.exports = {
    apps: [
      {
        name: "nodejs-app",
        script: "./server.js",
        env: {
          PORT: 8080
        },
        env_production: {
          NODE_ENV: "production",
          PORT: process.env.PORT 
        }
      }
    ]
  };

After successfully deploying the application, I set the following startup command in Azure Web App under Configuration -> Startup Command.

pm2 start ecosystem.config.js --no-daemon

Azure Web App Output:
