express-subdomain example

regester subdomains with express-subdomain

Install

Install package with npm or yarn

npm i express-subdomain

yarn add express-subdomain

How it works

Let's find out step by step

import modules

import subdomain from 'express-subdomain'

set subdomain offset

app.set('subdomain offset', 1)

subdomain offset is the number of dot-separated parts of the host to remove to access subdomain.

For instance, if you use localhost, set it to 1. And if you use example.co.kr, set it to 3.

regester subdomain

You can now re-register your sub-domain. Of course, the number of subdomains is not limited.

app.use(subdomain('api', api))
