This package allows for easily temporarily locking your scripts execution.
It might come in handy in cases such as CRON jobs that connect with unreliable APIS, where you're not 100% sure if your script won't fail at some point.
This package requires:
$ composer require desmart/laravel-padlock
DeSmart\Padlock\ServiceProvider
to your config/app.php
: /*
* Package Service Providers...
*/
DeSmart\Padlock\ServiceProvider::class,
$ php artisan vendor:publish --provider="DeSmart\Padlock\ServiceProvider"
config/padlock.php
- choose between Database and Filesystem driverThis package's purpose is to protect your script from being run on multiple threads.
It is useful for long-time backend jobs such as handling queries, or harvesting data from external APIs.

protected $description = 'Foo command utilizing Padlock';

/** 30 seconds padlock time to live - after that your padlock will be unlocked */
