i have done the following: install i18n-node modul and register in the express js. here is code.

var express = require('express')
  , routes = require('./routes')
  , http = require('http')
  , i18n = require("i18n");

  var app = express();

i18n.configure({
    // setup some locales - other locales default to en silently
    locales:['de', 'en'],
    // disable locale file updates
    updateFiles: false
});

app.configure(function(){
  ...
  app.use(i18n.init);
  ...
});
// register helpers for use in templates
app.locals({
  __i: i18n.__,
  __n: i18n.__n
});

after this set the following to get all request

// invoked before each action
app.all('*', function(req, res, next) {
    // set locale
    var rxLocal = /^\/(de|en)/i;
    if(rxLocal.test(req.url)){
        var arr = rxLocal.exec(req.url);
        var local=arr[1];
        i18n.setLocale(local);
    } else {
        i18n.setLocale('de');
    }
    // add extra logic
    next();
});

app.get(/\/(de|en)\/login/i, routes.login);

maybe this help.
