node.js - Express Applications throwing 500 on azure

Question

The following code runs perfectly locally...

var express = require('express');
var app = express();

app.get('/', function (req, res) {
    res.send("Hello World");
});

var port = 8080;

app.listen(port, function () {
    console.log('Server started and is listening on port ' + port);
});

But when i deploy it to azure I get a 500 error. Here is my findings...

1. I have taken this advice
2. Have tried all possible combinations of server.js, app.js, directory structure etc.

The code is being deployed from a local git repo.

Answer 1

Azure Web Apps (web sites) listen on ports 80 and 443 only. You can not listen on port 8080.

You'll need to listen on port process.env.PORT. And you can easily run both locally and in Azure by tweaking your port code to something like:

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