We’ll start by creating a new Laravel project. While there are different ways of creating a new Laravel project, I prefer using the Laravel installer. Open your terminal and run the code below: This will create a laravel-chatproject within the directory where you ran the command above. Before we start using Laravel event broadcasting, we first need...
If you don’t have one already, create a free Pusher account at https://pusher.com/signupthen login to your dashboard and create an app. Now, let’s fill in our Pusher app credentials. If you open the config/broadcasting.php, you’ll notice that Laravel is pulling some of Pusher credential from the .envfile: We need to modify the source a little bit h...
Our chat app will require users to be logged in before they can begin to chat. So, we need an authentication system, which with Laravel is as simple as running an artisan command in the terminal: This will create the necessary routes, views, and controllers needed for an authentication system. Before we go on to create users, we need to run the use...
Create a Message model along with the migration file by running the command: Open the Message model and add the code below to it: The message will have five columns: an auto increment id, user_id, message, created_at and updated_at. The user_id column will hold the ID of the user that sent a message and the message column will hold the actual messa...
We need to set up the relationship between a user and a message. A user can send many messages while a particular message was sent by a user. So, the relationship between the user and message is a one to many relationship. To define this relationship, add the code below to User model: Next, we need to define the inverse relationship by adding the c...
Let’s create the routes our chat app will need. Open routes/web.phpand replace the routes with the code below to define three simple routes: The homepage will display chat messages and an input field to type new messages. A GET messages route will fetch all chat messages and a POST messagesroute will be used for sending new messages. NOTE: Since we...
Now let’s create the controller which will handle the logic of our chat app. Create a ChatsController with the command below: Open the new create app/Http/Controllers/ChatsController.phpfile and add the following code to it: Using the auth middleware in ChatsController‘s __contruct() indicates that all the methods with the controller will only be a...
For the chat app view, we’ll be making use of Bootsnipp chat snippetwith some few modifications. Create a new resources/views/chat.blade.phpfile and paste into it: Notice we have some custom tags with the chat view, these are Vue components which we’ll create soon. The chat-messages component will display our chat messages and the chat-formwill pro...
To add the realtime interactions to our chat app, we need to broadcast some kind of events based on some activities. In our case, we’ll fire a MessageSent when a user sends a message. First, we need to create an event, we’ll call it MessageSent: This will create a new MessageSent event class within the app/Events directory. This class must implemen...
Once the MessageSent event is broadcast, we need to listen for this event so we can update the chat messages with the newly sent message. We can do so by adding the code snippet below to created() of resources/assets/js/app.js just after this.fetchMessages(): We subscribe to the chat channel using Echo’s private() since the channel is a private cha...
