I've been searching and I've found "solutions" to this problem, yet I still can't get this to work right.

The Scenario:

I'm building an Angular (version 1.2) website with the UI Router and running it on a Node server on localhost. I'm trying to make it have "pretty" url's with the $locationProvider and by turning html5(true) on. My website works fine when clicking through it, but when I try to navigate to a relative link path or refresh the link path the page breaks. I also intend to deploy this webapp to Heroku when completed:

RELATIVE LINK PATH:

http://localhost:8000/locksmith-services

PAGE OUTPUT RESULT

Cannot GET /locksmith-services

Steps I've taken:

1.) In my "index.html" < head >, I've set my base url to:

<base href="/"></base>

2.) In my app.js file (for Angular), I have it written as follows:

// App Starts
angular
    .module('app', [
        'ui.router',
        'ngAnimate',
        'angular-carousel'
    ])
    .config(['$urlRouterProvider', '$stateProvider', '$locationProvider', function($urlRouterProvider, $stateProvider, $locationProvider) {
        $urlRouterProvider.otherwise("/");

        $stateProvider
            .state('home', {
                url: '/',
                templateUrl: 'pages/home.html',
                controller: 'homeCtrl'
            })
            .state('services', {
                url: '/locksmith-services',
                templateUrl: 'pages/locksmith-services.html',
                controller: 'servicesCtrl'
            })
            .state('locations', {
                url: '/locksmith-locations',
                templateUrl: 'pages/locksmith-locations.html'
            })
            .state('payment', {
                url: '/locksmith-payment',
                templateUrl: 'pages/locksmith-payment.html'
            })
        // use the HTML5 History API
        $locationProvider.html5Mode(true);
    }])

3.) In my navigation, I have my html written as:

<div class="wrapper">
    <a ui-sref="home">
        <img src="images/logo.png" class="logo" alt="Austin Texas Locksmith" />
    </a>
</div>
<nav class="row navigation">
    <a class="mobile33" ui-sref="services" ui-sref-active="active" class="active">Services</a>
    <a class="mobile33" ui-sref="locations" ui-sref-active="active">Locations</a>
    <a class="mobile33" ui-sref="payment" ui-sref-active="active">Payment</a>
</nav>

4.) My server.js file (node server)

var express = require('express');
var app = express();

app.use(express.static(__dirname + '/front'));
var port = process.env.PORT || 8000;
app.listen(port);

What would be the best solution? Thanks in advance for your help.

Thanks to @trehyu for helping me get to this answer.

Like he wrote, I needed something setup on my server.js file that redirects the user to my "index.html" file.

So depending on your file structure...

BEFORE (not working)

var express = require('express');
var app = express();

app.use(express.static(__dirname + '/front'));
var port = process.env.PORT || 8000;
app.listen(port);

AFTER (working)

var express = require('express');
var app = express();

app.use('/js', express.static(__dirname + '/front/js'));
app.use('/build', express.static(__dirname + '/../build'));
app.use('/css', express.static(__dirname + '/front/css'));
app.use('/images', express.static(__dirname + '/front/images'));
app.use('/pages', express.static(__dirname + '/front/pages'));

app.all('/*', function(req, res, next) {
    // Just send the index.html for other files to support HTML5Mode
    res.sendFile('/front/index.html', { root: __dirname });
});

var port = process.env.PORT || 8000;
app.listen(port);

I hope this helps someone else!
