Laravel 5 Package Scheduled Tasks

Question

I\'m developing a package that has some scheduled tasks - is there way of registering / publishing them without affecting the base applications already set scheduled tasks?

Answer 1

You certainly can, all through the power of some basic object-oriented programming!

Step 1: Create Your Package's "Kernel" Console Class

Let's create a Kernal class within your package's Console directory where we will be extending App\Console\Kernel.

Step 2: Add the schedule method

Since we are extending the App Console Kernel, we'll want to add the relevant schedule method and call the parent class' implementation of it. This will ensure that any previously scheduled tasks carry through.

Step 3: Add your scheduled tasks

Now you may add your own scheduled tasks per normal.

$schedule->command('')->daily();

Step 4: Register It!

We'll want to bind the class to the container, and make it within our package's service provider's register method:

$this->app->singleton('acme.package.console.kernel', function($app) {
    $dispatcher = $app->make(\Illuminate\Contracts\Events\Dispatcher::class);
    return new \Acme\Package\Console\Kernel($app, $dispatcher);
});

$this->app->make('acme.package.console.kernel');

---

That should be all that's required!

Some things to take into consideration with this though:

1. Be up-front that your package has these bundled tasks. Developers don't like surprises (especially when it concerns tasks being automatically ran on their server).
2. Along with the first point, not every one will have the required cronjob set up on their server. They'll need to do this before your package's tasks will run automatically.
3. Provide a config option to disable the package's tasks from being auto registered, and documentation on how developers can register it themselves based on their own needs.
