How to run Nodejs App On Different Port Other Than Default 8080?

Question

I followed the link to create my first nodejs app in the app service

https://learn.microsoft.com/en-us/azure/app-service/quickstart-nodejs?tabs=linux&pivots=development-environment-vscode

but my app is running on port 8080 not 3000. I even added a new variable PORT:3000 in configuration>application settings but it didn't help.

Can someone please help on how one can use a different port?

Thanks

Answer 1

Set the PORT variable first

Azure Portal > Configuration > Application settings > Add a new application setting
PORT = 3000

then Check your app settings also

const port = process.env.PORT || 3000;  
app.listen(port, () => {
    console.log(`Server listening on port ${port}`);
});

then restart the application
