express-www-redirect
A pair of Express JS middlewares for redirecting:
- No-WWW hosts to WWW hosts
- WWW hosts to No-WWW hosts
This package has no opinion about whether you should use a WWW or No-WWW host, but that you should choose one or the other. A website that exists at both WWW and No-WWW hosts can cause confusion for search engines.
We use this package at Simplycoupons.co to redirect all of our No-WWW requests to our WWW subdomain.
Install
npm install express-www-redirect
Redirecting No-WWW to WWW
Require redirectNoWWWToWWW
:
const { redirectNoWWWToWWW } = require('express-www-redirect')
Apply the middleware before your routes:
app.use(redirectNoWWWToWWW(whitelistHosts, redirectStatusCode))
Redirecting WWW to No-WWW
Require redirectWWWToNoWWW
:
const { redirectWWWToNoWWW } = require('express-www-redirect')
Apply the middleware before your routes:
app.use(redirectWWWToNoWWW(whitelistHosts, redirectStatusCode))
Configuration
- whitelistHosts: An array of strings of whitelisted hosts that will not be redirected. Include port numbers for
localhost
, example:['localhost:3000']
. Default:[]
. - redirect: HTTP status code to apply to the redirect. Default:
301
.
Example Express server - No-WWW to WWW
var express = require('express');
const { redirectNoWWWToWWW } = require('express-www-redirect')
var app = express();
app.use(redirectWWWToNoWWW(['localhost:3000']))
app.get('/', function (req, res) {
res.send('Hello World!');
});
