How to route to multiple Angular apps via Express?

The problem, I have a server and client folder, instead client I have 2 Angular apps: 1 for website and 1 for dashboard.

Currently after I run the server, and hit the path / you get routed to the website app, once there I can't seem to route out to the dashboard app.

Folder structure: server/ client/ website/ dashboard/

The main.js inside of server/ which correctly routes to the website app, but can't route to dashboard/

//website api
=============
var website = express.Router();
app.use('/', website);
app.use('/', express.static("../client/website/"));
console.log(__dirname + "../client/website/");

website.use(function(req, res, next) {
    console.log(req.method, req.url);

    next();
});

website.get('/', function(req, res) {
    var path = 'index.html';
    res.sendfile(path, { 'root': '../client/website/' });
});

//dashboard api
===============
var dashboard = express.Router();
app.use('/dashboard', dashboard);
app.use('/', express.static("../client/dashboard/"));
console.log(__dirname + "../client/dashboard/");

dashboard.use(function(req, res, next) {
    console.log(req.method, req.url);

    next();
});

dashboard.get('/dashboard', function(req, res) {
    var path = 'index.html';
    res.sendfile(path, { 'root': '../client/dashboard/' });
});

The mainController routes config of the website:

.config(['$stateProvider', '$urlRouterProvider',
    function($stateProvider, $urlRouterProvider) {

        $stateProvider
            .state('home', { url: '/home' })

            .state('about', {
                url: '/about',
                templateUrl: 'views/about.html'
            })

            .state('login', {
                url: '/login',
                templateUrl: 'views/login.html'
            })

            .state('register', {
                url: '/register',
                templateUrl: 'views/register.html'
            });

        $urlRouterProvider.otherwise('/home');
}])

Once I hit http://localhost:9999/ the Angular app takes over: http://localhost:9999/#/home And I'm in the website views and cannot switch routes and see the dashboard app.

Below is the config in the mainController for the dashboard app

.config([
    '$stateProvider',
    '$urlRouterProvider',
    function($stateProvider, $urlRouterProvider) {

        $stateProvider

            .state('wallet', { url: '/wallet' })

            .state('wallet', {
                url: '/wallet',
                templateUrl: 'views/wallet.html'
            })

            .state('accounts', {
                url: '/accounts',
                templateUrl: 'views/accounts.html'
            })

            .state('settings', {
                url: '/settings',
                templateUrl: 'views/settings.html'
            })

            .state('help', {
                url: '/help',
                templateUrl: 'views/help.html'
            });

        $urlRouterProvider.otherwise('wallet');
}])

How would you change the routes in the Express app (main.js) to allow me to change Angular apps?

ie:

http://localhost:9999/#/home = website http://localhost:9999/#/dashboard = dashboard
