vhost-ts

Same usage as vhost but having in mind TypeScript and express for type handling

Open for PRs to handle connect types

Install

yarn add vhost-ts

or

npm install vhost-ts

API

import vhost from "vhost-ts";

vhost(hostname, handle)

Create a new middleware function to hand off request to handle when the incoming host for the request matches hostname. The function is called as handle(req, res, next), like a standard middleware.

hostname can be a string or a RegExp object. When hostname is a string it can contain * to match 1 or more characters in that section of the hostname. When hostname is a RegExp, it will be forced to case-insensitive (since hostnames are) and will be forced to match based on the start and end of the hostname.

When host is matched and the request is sent down to a vhost handler, the req.vhost property will be populated with an object. This object will have numeric properties corresponding to each wildcard (or capture group if RegExp object provided) and the hostname that was matched.

import vhost from "vhost-ts";
import express from "express";
 
const app = express();
 
app.use(
  vhost("*.*.example.com", function handle(req, res, next) {
    // for match of "foo.bar.example.com:8080" against "*.*.example.com":
    console.dir(req.vhost.host); // => 'foo.bar.example.com:8080'
    console.dir(req.vhost.hostname); // => 'foo.bar.example.com'
    console.dir(req.vhost.length); // => 2
    console.dir(req.vhost[0]); // => 'foo'
    console.dir(req.vhost[1]); // => 'bar'
  })
);
