  1. I’m having trouble adding foreign keys to my database in laravel using migrations. Since migrations can’t be reordered, I can’t put them in my table creation migrations directly without needing to hack the times so that things get created in the right order.
  2. In this post, we are looking at the steps necessary to create an Ubuntu droplet in DigitalOcean from scratch. This is the companion guide to the video series in Laravel 5.8 from scrath. Follow along with those to get the video guide.

What We’ll Build

This tutorial will demonstrate how to implement token-based authentication in an AngularJS and Laravel application. To do so, we’ll build a simple app that will authenticate users with a login form. If successfully authenticated, the user will be redirected to a view where they can get a list of all users in the database. The focus of the tutorial will be on how we can generate JWTs on the Laravel side, obtain them on the front-end and then send them along with every request to the API.

Installing the Laravel Dependencies

Let’s create a new Laravel application called jot-bot. Assuming you have Composer and the Laravel installer setup and ready to go, from the command line:

We should also add in the jwt-auth facades which we can do in config/app.php. Find the aliases array and add these facades to it:

Installing the AngularJS Dependencies

There are a number of things that need to happen on the front-end so that we can send a JWT with every request to the Laravel API after our user is authenticated. Namely, we need to keep the JWT in local storage once we retrieve it from the API and also need to add a header to every subsequent request that contains the token. We could write the appropriate JavaScript to accomplish this on our own, but a package has already been created that does a great job of it. Instead of spending extra effort, let’s make use of Satellizer.

Creating Some Test Data

Laravel comes with a migration for a users table out of the box and this is the only one we'll need for the tutorial. Let's run the migrations so that this table gets created in the database and then seed it with some test data. From the command line:

Creating the API Routes

Once we’ve confirmed that the database has been seeded properly, let’s get the API setup in routes.php.

Testing Out the API

By default, Laravel has CSRF token verification turned on, but since we’re using JWTs in a stateless manner now, we don’t really need CSRF tokens. We can turn this default behavior off by commenting out the VerifyCsrfToken middleware in Kernel.php.

Showing User Data

We’re going to return the data for all of the users in the database, but only if there is a token passed along with the request. We can make this happen by protecting our API with the middleware that comes with jwt-auth.

Setting up The Front-End

Now that the API is setup and the middleware is functioning properly we can create the front-end of our app.

Setting Up the Auth State

In our AuthController we are injecting $auth which is a service provided by Satellizer for communicating with the API and also $state so that we can handle redirects.

Setting Up the Users State

This controller has one method, getUsers, which makes an $http.get request to the API to fetch the data for all users. If the call is successful, the users data is placed on the vm.users key. If not, the error message that gets returned is placed on the vm.error key. Now let's reflect this data in a view:

Wrapping Up

In this tutorial we have seen how we can authenticate our AngularJS and Laravel applications with JSON Web Tokens. We secured our API with jwt-auth and setup middleware so that the user data only gets returned if the token is present. We then used Satellizer to set the user’s token in local storage and to add it to the Authorization header of every subsequent request to the API.

  • Setting the logged-in user’s data (such as name and email address) and their authentication status in local storage or on $rootScope so that we can pass their information around from state to state
  • A way to redirect the user to the login state if they become logged out somehow (for example, if the token expires)
  • How to log the user out and the implications of token-based authentication on logout
