I doubt anyone will ever need this but just in case. I had a scenario where I needed to deliver the hostname (without the port) through an .ejs variable. The hostname comes from the request header so that's easy to find and I simply used a .match with a ternary conditional to keep things clean.

var express = require("express"), app = express.createServer(); app.get("/", function( req, res ){ //Strip out port number var hostname = ( req.headers.host.match(/:/g) ) ? req.headers.host.slice( 0, req.headers.host.indexOf(":") ) : req.headers.host res.render( "index.ejs", { layout: false, hostname: "http://" + hostname }); });
