express-subdomain2path

Express middleware to add subdomains (or full domain) to the path so it can be handled by the express router

The Express Router can control routing based on paths out of the box, but not based on subdomains, this middleware will add the subdomain to the beginning of the path so you can have routes based on subdomains.

Install

npm install --save express-subdomain2path

Usage

var subdomain2path = require("express-subdomain2path");
var options = {
    ignoreDomains : ["admin.example.com","example.com"];
}
app.use(subdomain2path(options).converter);

Now if you visit about.example.com the app will use the /about route, but admin.example.com and example.com will still use the / route. loading the middleware without a config object will automatically ignore the root domain, ex: example.com, this will not work if your domain is behind a second-level ex: .co.uk in that case you'll have to set ignoreDomains, (See the options bellow for more info on config options);

Options

The subdomain2path function take an optional but recommended options object.

ignoreDomains

ignoreDomains is an array of domains (Strings) that should be ignored when converting subdomains to paths, this will especially be useful when you want to ignore some subdomains ex: ex1.example.com, if you omit this option only the top level domain will be ignored unless fullDomain is set to true.

Note: A domain in ignoredDomains will be ignored even if fullDomain is set to true.

fullDomain

Defaults to false, sets whether the full domain should be converted or not, leaving this as is will automatically remove the top domain from being converted, (using regex /[^\.]+\.[^\.]+$/).

Note: setting this to true will convert the full domain together with the TLD, ex: the path will become /com/example/ex1, if you only want the domain and not the TLD you can omit this setting and only set ignoredDomains to [".com"], which will have the desired effect.

reverse

Defaults to true, sets whether the order of domain levels should be converted in path, ex: given room1.org1.exmple.org when reverse is true it will give /org1/room1, setting it to false will give /room1/org1.

subPath

You can specify subpath under which the subdomains should be attached to the path, ex: setting subPath to subdomain will endup converting team1.org1.example.com to /subdomain/org1/team1/.
