Node.js Question

Error: listen EACCES OSx Node.js

I'm following a tutorial in a angularJS book and have to setup a server. This is the server.js file:

var express = require('express');
var app = express();
app.use('/', express.static('./'));

I get this error:

$ node server.js
throw er; // Unhandled 'error' event

Error: listen EACCES

I know already, that the Error EACCES means that i don't have access rights to the port 80, but i don't know how to fix this.
Any help much appreciated!

If you need to run the server on port 80 you should use a reverse proxy like nginx that will run using a system account on a privileged port and proxy the requests to your Node.js server running on an unprivileged port (> 1024).

When running in development environment you're pretty much free to run as root, but that is rather dangerous in production environment.

Here's a sample nginx config that will see if the request is for a file that exists in the filesystem, and if not, proxy the request to your Node.js server running on port 9000

upstream yournodeapp {
  server localhost:9000 fail_timeout=0;
  keepalive 60;

server {
  server_name localhost;
  listen 80 default_server;

  # Serve static assets from this folder
  root /home/user/project/public;

  location / {
    try_files $uri @yournodeapp;

  location @yournodeapp {
    proxy_pass http://yournodeapp;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
