AngularJS Framework : Token (JSON Web Token - JWT) based auth backend with NodeJS

This tutorial is the backend part of token based authentication.

The code is available here:
Token-Based-Authentication/Backend-Auth-NodeJS.

We may want to clone it:

$ git clone https://github.com/epic-math/Token-Based-Authentication.git

In the back-end project, there are three main files:

1. package.json is for dependency management.
2. models\User.js contains a User model that will be used for making database operations about users.
3. server.js is for project bootstrapping and request handling.

We need to define an environment variable: MONGO_URL which is used for the database connection URL:

export MONGO_URL="mongodb://localhost/"

Once clone the source, setup the MONGO_URL, we can install the dependent packages:

$ npm install

This command reads Backend-Auth-NodeJS's package.json file and downloads the following tools into the node_modules directory:

We can start our server by using the following code snippet(client.js):

// Start Server
app.listen(port, function () {
    console.log( "Express server listening on port " + port);
});

Run the server:

$ node client.js
Express server listening on port 3000
GET / 200 149.680 ms - 2704
GET /lib/ngStorage.js 200 13.399 ms - 1179
GET /scripts/app.js 200 17.246 ms - 1489
GET /scripts/controllers.js 200 14.306 ms - 1789
GET /scripts/services.js 200 1.924 ms - 1811
GET /partials/home.html 200 4.793 ms - 236

Our browser:

We finished the back-end service, and it can be used by multiple clients.

More detailed explanation about the cloned NodeJS codes will be added later.

Now, we want to move into the front-end project, and in next chapter (Token (JSON Web Token - JWT) based auth frontend with AngularJS), we will see an AngularJS project for token-based auth.
