Exploring AngularJS through interactive sessions

I am working on implementing a basic login system using express and angularjs. The angular js application is running on a different server (grunt server localhost:9000), while the express app is running on a separate port. In my express app, I have configured the following headers:

app.all('/*', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "http://localhost:9000");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  res.header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE");
  res.header("Access-Control-Allow-Credentials", "true");
  next();
});

My angular version is 1.0.7, which allows me to set defaults during the configuration step:

// Add COR ability
$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];

Also, setting withCredentials on the $http request:

$http({
   method : "GET",
   withCredentials : true,
   url : apiEndpoint + '/session'
}, success);

After logging in through my app, a session is established and a cookie is visible in the response. By inspecting the chrome developer tools, I can confirm that the connect session cookie is being sent with the subsequent request (the session call above). However, on the server side, the req.session property remains empty. While one solution could be hosting the angular app within express to avoid these issues, I prefer to maintain separate projects/servers for each.

This shows the /session request, including the attachement of the connect session cookie:

Answer №1

Let me make sure I understand your configuration correctly:

You have angularjs running on a grunt server connected to an express server.

Now, you are looking to access the session on the express server. In order to achieve this, you will need to establish a method for sharing the session data between these two servers. One effective solution would be to implement the redis-connect module (or alternatively, express-mongodb). This module allows the session object to be stored in a redis database, providing accessibility from both servers. Although I haven't utilized a grunt server personally, I have successfully implemented this setup with two separate express servers before. It's important to note that using MemoryStore is not suitable in this scenario, as it functions based on individual processes and does not facilitate shared memory across distinct servers.

Answer №2

After some experimentation, I managed to get everything functioning correctly. Initially, I decided to update to the latest version of Angular for certain values that couldn't be set globally on $http.

Within the angular config() process, I inserted the following code:

// Allowing CORS
$httpProvider.defaults.useXDomain = true;
$httpProvider.defaults.withCredentials = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];

In my express setup, I implemented an Angular middleware:

exports.angularHeaders = function(req, res, next){
    res.header("Access-Control-Allow-Origin", '{{insert your ui endpoint}}');
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    res.header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
    res.header("Access-Control-Allow-Credentials", "true");
    next();
};
