This package contains a job middleware that can funnel jobs in Laravel apps.
Permission was granted by Freek Van der Herten to copy Spatie's laravel-rate-limited-job-middleware, rename it, and maintain it on my own. As such, the vast bulk of this package is built on theirs. Thanks...! :-)
You can install the package via composer:
composer require telkins/laravel-job-funneling-middlewareThis package requires Redis to be set up in your Laravel app.
By default, the middleware will only allow 1 job to be executed at a time. Any jobs that are not allowed will be released for 5 seconds.
To apply the middleware just add the Telkins\JobFunnelingMiddleware\Funneled to the middlewares of your job.
namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Telkins\JobFunnelingMiddleware\Funneled;
class TestJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable;
public function handle()
{
// your job logic
}
public function middleware()
{
return [new Funneled()];
}
}When using rate limiting, including funneling, the number of attempts of your job may be hard to predict. Instead of using a fixed number of attempts, it's better to use time based attempts.
You can add this to your job class:
/*
* Determine the time at which the job should timeout.
*
*/
public function retryUntil() : \DateTime
{
return now()->addDay();
}You can customize all the behavior. Here's an example where the middleware allows a maximum of 3 jobs to be performed at a time. Jobs that are not allowed will be released for 90 seconds.
// in your job
public function middleware()
{
$funneledMiddleware = (new Funneled())
->limit(3)
->releaseAfterSeconds(90);
return [$funneledMiddleware];
}By default, the middleware will use the default Redis connection.
The default key that will be used in redis will be the name of the class that created the instance of the middleware. In most cases this will be name of the job in which the middleware is applied. If this is not what you expect, you can use the key method to customize it.
Here's an example where a custom connection and custom key is used.
// in your job
public function middleware()
{
$funneledMiddleware = (new Funneled())
->connection('my-custom-connection')
->key('my-custom-key');
return [$funneledMiddleware];
}If you want to conditionally apply the middleware you can use the enabled method. It accepts a boolean that determines if the middleware should funnel your job or not.
You can also pass a Closure to enabled. If it evaluates to a truthy value the middleware will be enabled.
Here's a silly example where the funneling is only activated in January.
// in your job
public function middleware()
{
$shouldFunnelJobs = Carbon::now()->month === 1;
$funneledMiddleware = (new Funneled())
->enabled($shouldFunnelJobs);
return [$funneledMiddleware];
}These methods are available to be called on the middleware. Their names should be self-explanatory.
