Not working...

[LucGranato]

My server code is the following...

var util = require('util');

var subdomain = require('express-subdomain');
var express = require('express');

passport.use(new BasicStrategy(

    function(userid, password, done) {

        User.findOne({ email: userid }, function (err, user) {

            if (err) { return done(err); }
            if (!user) { return done(null, false); }
            if (!user.verifyPassword(password)) { return done(null, false); }
            return done(null, user);
        });
    }

util.log("Server running on port 3000");

Does anyone know why it's not working?

Even when I call ( api.beetrack.com.br/login ) I get response from app.use('/', function(req, res) { ......

Thanks in advance!

Hi @LucGranato, great find!

It's because the it's a multi-level TLD (.com.br) - express splits the url by '.' and the last two items in the array are considered the 'host' - everything before them will be added to the req.subdomains array, which this module uses to check against.

Therefore, to make it work in your case, add '.beetrack' to the string you pass to subdomain:

app.use(subdomain('api.beetrack', api));
app.use(subdomain('device.beetrack', device));
app.use(subdomain('mobile.beetrack', mobile));

PS. I've wrote some tests to check that this works in #18. I'll make sure and update the readme describing this 😄.

Thanks a lot @bmullan91 !
It worked perfectly! Congrats..
Muito obrigado (from Brazil)..

This could also be solved with subdomain offset in http://expressjs.com/en/4x/api.html#app.settings.table

@MoLow
Please I have some problem with express-subdomain
app.js
var express = require('express');
var router = express.Router();
var app = express();
var index = require('./routes/index');
app.use('/', index);
app.listen(3000);

and index.js

const
subdomain = require('express-subdomain'),
express = require('express'),
router = express.Router();

function init(server) {
server.use(subdomain('api', router))

server.get('/', function (req, res) {
    res.redirect('/home');
});

router.get('/', function(req, res) {
res.send('Welcome to our API!');
});
 
router.get('/users', function(req, res) {
	res.json([
		{ name: "Brian" }
	]);
});
	
server.get('*', function (req, res, next) {
    console.log('Request was made to: ' + req.originalUrl);
    return next();
});

}

module.exports = {
init: init
};

getting this error

throw new TypeError('Router.use() requires a middleware function but got a ' + gettype(fn))
