Node / Angular app Uncaught SyntaxError: Unexpected token <

You are missing some settings in your app file on the server to handle all of the requests being made to the server. Here is a basic sample working express file, which you can modify to fit your environment:

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

app.use('/js', express.static(__dirname + '/js'));
app.use('/bower_components', express.static(__dirname + '/../bower_components'));
app.use('/css', express.static(__dirname + '/css'));
app.use('/partials', express.static(__dirname + '/partials'));

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

This file uses express.static to serve any content which is in the specific directory regardless of name or type. Also keep in mind that Express use statements are processed in order, and the first match is taken, any matches after the first are ignored. So in this example, if it isn't a file in the /js, /bower_components, /css, or /partials directory, the index.html will be returned.
