How to host an AngularJS app in Heroku using Node.js WITHOUT using yeoman?
Question
I'm trying to push a Hello World build with AngularJS into Heroku using Node.js. BUT with multiple views(partials).
I first deployed a Hello World without using ngRoute, meaning: without partials. That was fine and smooth. Then, I tried to push 2 simple partials. But I believe the issue is hosting the application and at the same time asking for partials. I know it is not the right approach and I want your advice.
This is my index.html:
<!DOCTYPE html>
<html ng-app="main">
<head>
<meta name="name" content="something">
<title></title>
</head>
<body>
<section ng-view=""></section>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.3/angular.min.js" type="text/javascript" charset="utf-8"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.3/angular-route.min.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" charset="utf-8">
angular.module('main', ['ngRoute'])
.config(['$routeProvider', '$http', function ($routeProvider, $http){
console.log('hola');
$routeProvider
.when('/', {
resolve: **??? I tried with templateUrl but did not work either**
,controller: 'indexCtrl'
})
.when('/second', {
resolve: **???**
,controller: 'secondCtrl'
})
.otherwise({
redirectTo: '/'
});
}])
.controller('indexCtrl', ['$scope', function ($scope){
$scope.helloWorld = "Hello World";
}])
.controller('secondCtrl', ['$scope', function ($scope){
$scope.helloWorld = "World Hello";
}]);
</script>
</body>
</html>
Partial 'templates/second.html'
<h1>{{ helloWorld }}<h1>
<a href="#/" title="">Go to First</a>
Partial 'templates/index.html'
<h1>{{ helloWorld }}<h1>
<a href="#/second" title="">Go to Second</a>
My express app:
var express = require('express'),
app = express();
app.set('view engine', 'html');
app.get('/', function(req, res) {
res.sendfile('index.html', {root: __dirname })
});
app.get('/index', function (req, res){
res.sendfile('templates/index.html', {root: __dirname })
});
app.get('/second', function (req, res){
res.sendfile('templates/second.html', {root: __dirname })
});
var server = app.listen(process.env.PORT || 80);
And obviously, Procfile:
web: node index.js
All the tutorials that I've found so far use Yeoman but I don't want to use Yeoman or any other scaffolding (if that is what that is) tool.
Q: Is it possible to host an AngularJS app in the same Heroku application where I'm storing the partials? If so, what am I doing wrong? If not, what is the best approach?

Well, I don't know why I got a down vote. But any way, I found my issue looking at this example.
The actual issue was that I was not making "public" the directory with express:
app.use(express.static(__dirname));
Here is the hello world
index.html
<!DOCTYPE html>
<html ng-app="main">
<head>
<meta name="name" content="something">
<title></title>
</head>
<body>
<section ng-view=""></section>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.3/angular.min.js" type="text/javascript" charset="utf-8"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.3/angular-route.min.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" charset="utf-8">
angular.module('main', ['ngRoute'])
.config(['$routeProvider', function ($routeProvider){
console.log('hola');
$routeProvider
.when('/', {
templateUrl: 'templates/index.html'
,controller: 'indexCtrl'
})
.when('/second', {
templateUrl: 'templates/second.html'
,controller: 'secondCtrl'
})
.otherwise({
redirectTo: '/'
});
}])
.controller('indexCtrl', ['$scope', function ($scope){
$scope.helloWorld = "Hello World";
}])
.controller('secondCtrl', ['$scope', function ($scope){
$scope.helloWorld = "World Hello";
}]);
</script>
</body>
</html>
Server / index.js
var express = require('express'),
app = express();
app.use(express.static(__dirname));
app.get('/', function(req, res) {
res.sendfile('index.html', {root: __dirname })
});
var server = app.listen(process.env.PORT || 80);
Procfile
web: node index.js
templates/index.html
<h1>{{ helloWorld }}<h1>
<a href="#/second" title="">Go to Second</a>
templates/second.html
<h1>{{ helloWorld }}<h1>
<a href="#/" title="">Go to First</a>
I hope this helps someone.
To answer my question. Yes, it is possible, what I was doing wrong is not making the templates(files) accessible. If you want to have extra security on what can be accessible you could create a folder called, for example, public. Then make that directory static:
app.use(express.static(__dirname + '/public'));
then you can also have different routes to communicate with your application even RESTfully. Like:
app.get('/users', function(req, res) {
res.json({...});
});
