Node web server redirecting all requests

README.md

A Node.js web server, with zero dependencies, which redirects all requests to a URL provided at runtime.

Useful for redirecting Elastic Beanstalk apps to a new location. Just deploy this as a new version, then set the REDIRECT variable.

Run with node server http://google.com or set REDIRECT=http://google.com && node server

server.js

var http = require('http');

var port = process.env.PORT || 3000;
var redirectUrl = process.env.REDIRECT || getArg(2);

if (!redirectUrl) {
  console.error('No redirect URL setup. ' +
      'Please specify a command line argument or "REDIRECT" variable.');
  process.exit(1);
}

var server = http.createServer(function(req, res) {
  res.writeHead(302, {
    'Location': redirectUrl
  });
  res.end();
});

server.listen(port, function () {
  console.log('Web server running on port %s and redirecting to %s',
    port, redirectUrl);
});

function getArg(index) {
  if (process && process.argv && process.argv.length >= index -1) {
    return process.argv[index];
  } else {
    return null;
  }
}
