Node / Angular app Uncaught SyntaxError: Unexpected token < - javascript

I'm following this node/angular tutorial and am getting the following errors:
I'm bootstrapping my app through node, which renders index page:
module.exports = function(app) {
app.get('*', function(req, res) {
res.sendfile('./public/index.html');
...
});
Which renders:
<html ng-app="DDE">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.16/angular.min.js"></script>
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers/main.js"></script>
</head>
<body>
This is the index page
<div ng-view></div>
I'd like Node to handle the initial page load, but Angular to handle the rest of the routing. The problem is here: It doesn't seem my angular routing is working. I put a self-exec fn run() in there to test, but it's not being called.
I'm simply trying to test display the testpage.html template:
app.js file:
angular
.module('DDE', [
'ngRoute'
])
.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/test', {
run : (function() {
alert('hit');
})(),
templateUrl: '../html/partials/testpage.html'
}).
otherwise({
redirectTo: '/test'
});
}
]);
The angular error isn't very helpful. I'm not sure what Unexpected token < means as I cannot find where I've added an extra < anywhere.
EDIT:
app.get('/', function(req, res) {
res.send('./public/index.html');
});
It should be able to find the stuff in bower components as the pathing is correct:
root/bower_components/angular/angular.js
root/bower_components/angular-route/angular-route.js

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.

I was able to resolve my issue with the unexpected token by moving my server.js file from the DIST directory into the directory above.
So my folder/file structure looks like this:
webroot - root folder
server.js
dist (folder)
browser (subfolder)
server (subfolder)

Why am i getting a 404 js file, while including a script tag?

index.html
<head>
<script src="/main.js"></script>
</head>
Error:
GET http://localhost:3000/main.js
Structure
Project
app.js
view
index.html
main.js
I've tried src="main.js". /view/main.js
Very basic, but dont want to get stuck on this any longer... sigh.
if it helps my app.js file has this:
app.get('/', function (req, res) {
res.sendFile(__dirname + '/view/home.html');
});
So, according to your comments - you are serving only the 'index.html' file instead of whole directory.
Try this code:
var express = require('express');
var path = require('path');
var app = express();
app.use(express.static(path.join(__dirname, 'view')));
//... other settings and server launching further
If you want to set serving static files to particular route - extend 'app.use' line with '/your-route', like this:
app.use('/your-route', express.static(path.join(__dirname, 'view')));
After that you can use <script src="main.js"></script> in your index.html

how to resolve ExpressJS routing when using AngularJS html5Mode (back4app/Parse-Server)

I'm using back4app BaaS service that uses Parse-Server. For the ClientSide I'm running AngularJS with html5Mode(true);
My problem is that this is NOT working: http://app.rizop.tv/dashboard
While this is working right: http://app.rizop.tv
Any idea how to fix expressJS to handle my routes in the right way?
I have this config:
cloud\app.js
// Helper modules that will be used
var path = require('path');
var bodyParser = require('body-parser')
// This imports the Router that uses the template engine
var index = require('./routers/index');
// Sets the template engine as EJS
app.set('view engine', 'ejs');
// This defines that the 'views' folder contains the templates
app.set('views', path.join(__dirname, '/views'));
// These options are necessary to
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
// This bind the Router to the / route
app.use('/', index)
// Starts listening in the routes
app.listen();
cloud\routers\index.js
// Importing express
var express = require('express');
// Creating a Router
var route = express.Router();
// Defining a route that binds the GET method
route.get('/', function(req, res) {
// This is the code that renders the template
res.render('index', {testParam: 'Back4Apper'});
});
module.exports = route;
cloud\views\index.ejs
<!doctype html>
<html>
<head>
<meta charset="utf-8">
...
</body>
...
</body>
</html>
Here is my app structure:
You can make it work by making little changes in app.js and root html file
I assume you already defined $locationProvider.html5Mode(true); where you defined your routes. Then define base href in your index html
<head>
<base href="/">
...
</head>
This answer might be helpful to configure your server
The file at cloud/app.js should not have app.listen() on its final line, due to the fact that you are using Cloud Code. Can you please try that?
I have ran into the same problem and did the following
I've put this route as the last option, so when the express router ran out of options it will render the index file where is the angular app. Angular internal router will resolve that route and draw the view.
router.get('*', function (req, res) {
res.render('index', {testParam: 'Back4Apper'});
});
Obviously you can write a smarter regex instead of * according to your needs but you get the idea.

Node Express server deep linking not working with AngularJS html5Mode

(Update: I solved the problem. Just look at the end of the question)
I am running with this problem that seems trivial to me, but I am very frustrated because I am not able to figure it out:
I scaffolded an Angular application using yeoman generator-angular. I need to use the html5mode of Angular to get rid of the hashtag (please, see app.js below). I am using a node express server (see server.js) to run the app built with grunt build.
As required, I added the option in the server to redirect to index.html when accessing the app from any specific route. It works with one level of "routing", i.e., localhost:8080/research, but it does not work for two "levels" or more, i.e., localhost:8080/research/human. In this case, when refreshing the browser, I get this error:
The stylesheet http://localhost:8080/research/styles/vendor.8089f103.css was not loaded because its MIME type, "text/html", is not "text/css". human
The stylesheet http://localhost:8080/research/styles/main.e7eff4cf.css was not loaded because its MIME type, "text/html", is not "text/css". human
SyntaxError: expected expression, got '<' vendor.01f538ae.js:1:0
SyntaxError: expected expression, got '<'
I have searched everywhere, I have tried all sort of options, but I am not able to fix it. I would really appreciate some help, please!

console.log('Node Express server listening on http://%s:%d', server.address().address,8080);
}
else {
console.log('No /dist folder, did not start the server');
}
Update: Solution
Thanks to the comments of the users, I asked the question in a different way and found the solution that make it works here. That is, the <base href="/"> tag must be located before the <link rel="stylsheet"..> tags (what a hard time I got for such a stupid thing!)
Why not use nested routing in angular routing like this ?
https://github.com/angular-ui/ui-router
I wanted this to be just a comment but I can't yet, Have you tried placing the html5 mode below your routes ?
Can remove the if statement if you do not need it.
.when('/research/fly', {
templateUrl: 'views/research-fly.html',
controller: 'ResearchController'
})
.otherwise ({
templateUrl: 'views/notyetready.html',
});
if(window.history && window.history.pushState){
$locationProvider.html5Mode(true);
}
});
Maybe try using a different pattern to match against that sounds like the cause of the problem
app.all('/**/*', function(req, res, next)
However I would ask why are you serving the static files with node + express? If all you want is a static file server for local development why not try grunt-serve
Then if you want to serve the static files on a server you can use nginx which works really well with angular in html5 mode

nodejs/express include local js file

Here is my current folder structure
css
app.css
js
app.js
node-modules
index.html
node-server.js
package.json
The node-server is hosting index.html, but I can't figure out how to get the app.js and app.css files to get loaded.
index.html loads them with:
<script src="js/app.js"></script>
<link rel="stylesheet" type="text/css" href="css/app.css"/>
Here is the error message:
Failed to load resource: the server responded with a status of 404 (Not Found)
2http://localhost:3000/css/app.css Failed to load resource: the server
responded with a status of 404 (Not Found)
I know i need to require or load module or something, just can't figure out what.
Thanks
Reason
Node.Js does not server static content on it's own, routes has to defined for serving static content via Node.
Solution(Manual):
var express = require('express'),
path = require('path'),
app = express();
app.get('/index.html',function(req,res){
res.sendFile(path.join(__dirname + '/index.html'));
});
app.get('/css/app.css',function(req,res){
res.sendFile(path.join(__dirname + '/css/app.css'));
});
app.get('/js/app.js',function(req,res){
res.sendFile(path.join(__dirname + '/js/app.js'));
});
app.get('/', function(req, res) {
res.redirect('index.html');
});
app.listen(8080);
Better Solution:
Directory Structure:
public
css
app.css
js
app.js
index.html
CODE:
var express = require('express'),
path = require('path'),
app = express();
// Express Middleware for serving static files
app.use(express.static(path.join(__dirname, 'public')));
app.get('/', function(req, res) {
res.redirect('index.html');
});
app.listen(8080);
As Tomasz Kasperek pointed out, you need to let Express know that you intend to host these files in a static directory. This is technically called defining static middleware.
This should look something like:
var express = require('express');
var app = express();
// first parameter is the mount point, second is the location in the file system
app.use("/public", express.static(__dirname + "/public"));
It's super simple and I suggest you go the route of making some sort of public folder, rather than bothering to make specific files and folders static.
Then the files would simply be referenced like so from the root index.html:
<link href="public/css/reset.css" rel="stylesheet" type="text/css">
Hope this helps you!
I got it to work by using this syntax
app.use(express.static('public'));
Copy the css and js files under the 'public' directory
and then add the reference in the index.html file
<link rel="stylesheet" href="/css/reset.css">
//we are in ./utils/dbHelper.js, here we have some helper functions
function connect() {
// connect do db...
}
function closeConnection() {
// close connection to DB...
}
//let's export this function to show them to the world outside
module.exports = {
connect(),
closeConnection()
};
// now we are in ./main.js and we want use helper functions from dbHelper.js
const DbHelper = require('./utils/dbHelper'); // import all file and name it DbHelper
DbHelper.connect(); // use function from './utils/dbHelper' using dot(.)
// or we can import only chosen function(s)
const {
connect,
closeConnection
} = require('./utils/dbHelper');
connect(); // use function from class without dot

Simple error including Javascript files into a test app using basic MEAN example

I'm taking a course (on MEAN) and it starts by trying to get something running end-to-end. The point now is to add in the Javascript necessary to make Angular work. I'm having some kind of simple problem including the scripts.
The error I'm getting is (firebug), which appears to complain about the entire index.html file, is:
The Jade code is short. It is an index.jade file which extends a layout.jade file which includes in all the js files:
extends ../includes/layout
block main-content
section.content
div(ng-view)
h2 some regular text 5
This produces the following index.html file:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="/css/bootstrap.css">
<link rel="stylesheet" href="/vendor/toastr/toastr.css">
<link rel="stylesheet" href="/css/site.css">
</head>
<body ng-app="app">
<script type="text/javascript" src="/vendor/jquery/jquery.js"></script>
<script type="text/javascript" src="/vendor/angular/angular.js"></script>
<script type="text/javascript" src="/vendor/angular-resource/angular-resource.js"></script>
<script type="text/javascript" src="/vendor/angular-route/angular-route.js"></script>
<script type="text/javascript" src="/app/app.js"></script>
<section class="content">
<div ng-view></div>
<h2>some regular text 5</h2>
</section>
</body>
</html>
================ UPDATE ========
It appears Node is substituting the index.html file for the assets. The project directory structure is:
The server.js file which node runs is:
var express = require('express');
var stylus = require('stylus');
// set env variable to determine if in production or development mode; this contains environment if set my MODE
var env = process.env.NODE_ENV = process.env.NODE_ENV || 'development';
// create express application
var app = express();
function compile(str, path) {
return sytle(str).set('filename', path);
}
// configure express
//app.set('views', __dirname + '/server/views');
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(stylus.middleware({
src: __dirname + '/public',
compile: compile
}));
console.log("dirname:" + __dirname);
app.use(express.static(__dirname + '/public'));
//app.use(express.static(path.join(__dirname, '/public')));
app.get('/partials/:partialPath', function(req, res) {
res.render('partials/' + req.params.partialPath);
});
app.use(express.logger('dev')); //- logger no longer bundled with Express
app.use(express.bodyParser());
// add routes:
// We won't tell the server specifically what routes to handle. We'll have the client-side be
// responsible to server up and 404 notices. Client-side will have to specify all routes.
// Other solution is to coordinate your routes, so that every client route is also listed on the server.
// Far more customary to have a server side have a catch all that lists up a 404 page.
app.get('*', function(req, res) {
res.render('index');
})
var port = 3030;
app.listen(port);
console.log("listening on port: " + port + " ...");
This looks like a path issue as the page is not able to access your assets directory. Make sure your public folder is set right in your node server code. It should be along the lines of app.use(express.static(path.join(__dirname, 'public_folder_name')));. Looking at your folder structure, your server.js is nested in server folder and not at the same level as your public folder. Try app.use(express.static(__dirname + '/../public'));
