false" I'm on window with XAMPP and certification auto signed generated by XAMPP. These are the lines of importance, starting at the top: This is the
that wraps every comment, and is the
that we want to loop through. Follow the documentation to learn more about the dashboard. The magic revolves around the show page of our video. I have hardcoded a default comment to demonstrate this.

Now that we have our new comments table setup, its time to solidify the relationships we setup in the previous step. I have already done this if you are using the example code, but remember to do this on your own projects before you try to use a scripts section. This is a great start to a blog, but now its time to build a commenting system so that users can leave comments on our posts. Add a user to the Videos table migration: We have a post route to store a new video, and a show route which will let the user know the current status of his/her uploaded video.

This is what sets up that two way binding between the text in this textarea and the commentBox Vue object.

Therefore we add our own host and port configuration to 'pusher' section in config/broadcasting.php: In our bootstrap.js file we need to tell Laravel Echo to use the alternative host and port (wsHost, wsPort): Although we are not using Pusher, we still need to supply some Pusher configuration in our .env environment file: We need to recompile bootstrap.js, as discussed in the Tips and Tricks section, by running npm run dev (or watch / prod). These are new things that happen with our application that we want to send to all of our clients. Before we even mess with comments, we need to setup a database table to persist any comments in our system. In order to ensure that we have a user_id whenever we save a new comment, then we need to make sure that a user submitting the comment has been authenticated. They are really helpful if you want to show real-time activities from your users (or perhaps some queue jobs).

Again, we would probably want to do something more visual to our users in a production app, but this will work for our tutorial.

This means that all of the comments will be loaded into the DOM via Vue.js and Vue.js will manage the comments for us. This comment is hardcoded though, and we need to make it dynamically load the real comments for each post. This is the beauty of Vue.js! Let’s start by working with the migration. Now that comment should come back to the page after the page is refreshsed and displayed it to the users. So things should be pretty simple. For example, imagine that a user can upload a video, which then needs to undergo a time intensive post-procesing task. These link to the id columns in the users and posts tables respectively. Guest users should have access to viewing comments, so we want to put this route outside of the api authentication route group, so that anyone will have access to this route, even if they are logged out or do not have an account.

Most of the hard work already exists within the postComment() method that we already wrote. It also will receive events from the web server and then distribute them to any connected clients. As we have mentioned in other sections of this tutorial series, the goal of this series is to learn how to use Websockets in Laravel and understand Laravel Echo. Finally ->get() completes the query and puts it all together.

Since we will be useing Vue.js later on to submit new comments, we will use Vue.js now to load the comments.

So there we go, we have methods available to both get all of the comments of the current post, and also to submit a new comment for this post. npm install --save laravel-echo pusher-js, composer require pusher/pusher-php-server. Of course as you grow your project you will probably have more actions needed, but this is all that’s necessary for our tutorial. You can see that we dynamically change the {post-id} portion based on the current post.

Now that we have our routes and controller logic setup, its time to impliment everything into our application.

[Part #2 – Directory (file) changes], Websockets in Laravel – Part 2: Creating Comments AJAX. HTTP is a one-time process. Lastly the .catch() block is the other part of the javascript promise, which runs if some sort of error occurs. If the closure as defined below returns true, the user has access. We translate a serialized JSON payload into a visual representation that the user is looking for. By writing v-for="comment in comments" inside of this

we are telling Vue to loop through the comments array and reference each iteration as comment.

If you frequent the DevMarketer site or the DevMarketer YouTube Channel than you are very familiar with sending web requests like GET, POST, UPDATE / PATCH, and DELETE.

When using Vue, we can define an option called mounted() {} in our Vue instance, which will run one time when the Vue instance finishes mounting (completes loading).

By using Channels we can organize our events to make sure that events only get distributed to the appropriate users. This is completely expected! In Vue.js the way you establish an event listener is with the v-on directive. Another way to test it is to manually add a new comment in your database for that post ID and then refresh the page. The default location of the dashboard is /laravel-websockets from your root path of the demo application and is automagically available. A Channel is an organizational element of websockets. In fact live chat applications are actually quite simple to build once you understand the fundamentals of websockets. This creates a controller called CommentController.

The first method is getComments() which will get all the comments for the current post, and the second method is postComment() which is what actually submits a new comment to be saved into our database.

This adds the two relationships and makes sure that we can mass-assign the new user_id and post_id columns. This means basically that we can create web applications that feel like native applications in the browser. We haven't created any of these yet, so let's start by scaffolding the ProcessVideo job: Since we want to have a reference to the video that needs processing, accept the $video in the constructor.

This will create both the Comment model and a migration for a new comments table to go with it.

Don't forget to import the Video and VideoWasProcessed classes.

So as you can see, I already have a basic HTML structure for the blog post, and for the comment. You might notice that we use this.comments.unshift(response.data) to add the new comment to this array. Your email address will not be published. Within this mounted(), we will call our getComments() method. Therefore I wanted to dedicate a small section to hopefully clear things up. This means we can let a client know about new information or changes in real-time, and update it onto their screens so they see things immediately as they happen without needing to refresh the page. Imagine the possibilities of being able to send information back and forth to the server without a page refresh and knowing it gets there nearly instantly. Now looking at the Store action, notice that when we store the comment we don’t pass in the post_id value. This will allow us access to the currently logged-in user’s ID.

They offer a free account which offers a maximum of 100 simultaneous connections, 200 000 messages a day and unlimited channels. This will run that method, which submits the API request to our server telling it to create a new comment. Create a public channel that is subscribed to on every page of your site. This isn’t necessary we could have easily just passed in the post id with the request headers, but I decided to match the URL format that was used with the index action. Now as you would expect, we have our migrations setup, we have our model, we have our routes, and now its time to actually create our controller so we can start writing the code necessary to save a new comment into the database. But I wanted to show you how it might look if you implimented avatars. Now, you should see that our demo application still works but now handling the WebSockets locally. Once the server sends us back a response it can not change or update that response, just like how you can not change the content of a text/SMS message after it has been sent. Click here to see the Websockets Series Overview, Mastering Websockets in Laravel – Part 1: Setup and Configuration, Ultimate Guide: Deploy Laravel 5.3 App on LEMP Stack (Ubuntu 16 and Nginx), What is New in Laravel 5.3? We dynamically insert the post.id just like we did in the getComments() method to make sure that the correct post ID is associated with this comment.

First, we'll scaffold the default Laravel authentication and a Video model with a migration and a controller. This is what it looks like (remember that this is only a portion of the resources/views/posts/show.blade.php file): For the most part you don’t need to change the HTML that is already in our demo project. I love this, keep it up nice work Devmarketer, Your email address will not be published. En cambio, Laravel-WebSocket es gratis, su configuración es realmente simple y esta construido sobre Ratchet, un paquete de bajo nivel que trabaja con web sockets. If the user is not logged in, than calling Auth::user()->toJson() would output an error. WebSockets is a relatively young TCP protocol, finalized in 2011, which enables two-way communication between the server and a user's browser.

Now that we know how awesome websockets can be, lets talk about how they work.

Events can also pass a serialized payload. The VideoProgress.vue component consists of a data variable processing which holds information on the processing status of the video. Now that this.comments contains an array of all our post comments, we can display that on the screen by looping through this object using Vue in our HTML.

Now, we need to get our credentials from Pusher.com. We often combine other javascript libraries to help us do this, such as Vue.js, React, or jQuery. Has it been published yet? The web server can not connect to the browsers directly because it runs on the HTTP protocol.

Now inside of the new controller, we want to add some logic for our index and store actions (these are the two actions we referenced when setting up our routes).

This means that our whole page is accessible and controllable with this Vue instance. This is a strange default browser behavior, but its something we need to accept. In this post I want to explain how to get started with realtime broadcasting in Laravel using WebSockets.

Once again we use axios to do this, but this time we use axios.post to send it as a POST method instead of a GET method. The three main components and how they work can be seen here.

You can see that we added another view directive on the
