NodeJS + ExpressJS: Strip out port from

/ Published in: JavaScript
Save to your folder(s)

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.

Copy this code and paste it in your HTML
  1. var express = require("express"),
  2. app = express.createServer();
  4. app.get("/", function( req, res ){
  5. //Strip out port number
  6. var hostname = ( ) ? 0,":") ) :
  8. res.render( "index.ejs", {
  9. layout: false,
  10. hostname: "http://" + hostname
  11. });
  13. });
