The job class uses the Dispatchable trait, this means that you can dispatch the job directly from the job itself, without passing it to the dispatch() or Job::dispatch functions: DownloadVideo :: dispatch () Replace the routes/web.php file with the following contents: Route :: get ( '/', 'HomeController' ) -> name ( 'home' ) Route :: post ( 'prepare', ) -> name ( 'prepare' ) Route :: get ( 'status/ We need to store the downloaded videos somewhere into our project, so, go ahead and create a new folder named downloads inside the storage/app/public folder: mkdir storage/app/public/downloads php artisan storage:link We need at least two controllers, one for viewing the home page and the other one to take care of the video requests: php artisan make:controller HomeController php artisan make:controller DownloaderContoller Refer to the documentation to install the Laravel installer. So, let’s get started by creating a new Laravel project: laravel new video-downloader cd video-downloader In this project, I will be using youtube-dl to download the videos youtube-dl supports a variety of websites, such as Youtube, Vimeo, Facebook, etc, so, I suppose that you have youtube-dl installed on your computer. Let’s put the queues into practice and get our hands dirty by creating a real project. In this post, I’ll show you how could you build a youtube download by using queues, so, let’s get started. async): When you execute something asynchronously, you can move on to another task before it finishes.Īn example is uploading a video file on youtube, it’ll take some time until youtube finishes processing the video file. The signing up process is a good example when the user signs up, she waits until her data will be saved into the database and then she’ll be notified immediately.Īsynchronous (abbr.
sync): when you execute something synchronously, you wait for it to finish before moving on to another task. vs Async.īefore we dive into Laravel queues, let’s discover two important terms. So, how could we improve our websites by letting the time-consuming processes to be run in the background? Sync. In addition to that, If the user requests a large file, then he might get an error indicating that the request cannot be accomplished due to 504 Gateway Time-out. It’s because the heavy processing requests need to be run asynchronously, so the user won’t be waiting for a very long time until the web browser sends back the requested file. Without a queueing system, we’re going to have a big problem, to be honest, it’s impossible to create such a website without queuing. Then the website will download that particular video file and sends it back to the web browser. it’s all start by asking the guest to enter a valid video link. Imagine you are building a website that can download videos from several video providers such as Youtube, Vimeo, etc.
