Confused - AppServiceProvider.php versus app.php

Question

Where do I specify my bindings exactly? It seems I can do it in either of these files.

config/app.php Inside of 'providers' =>

app/Providers/AppServiceProvider.php Inside of register()

Answer 1

If your bindings are not related to App, then I would create a new ServiceProvider class where I overwrite the register method with my new binding, then you have to let Laravel know that this class exists registering as a Provider in your config/app.php providers list, that is:

app/Providers/MyNewClassServiceProvider.php

<?php namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class MyNewClassServiceProvider extends ServiceProvider {
 public function register()
 {
    $this->app->bind(
        'App\Repository\MyNewClassInterface',
        'App\Repository\MyNewClassRepository'
    );
 }
}

config/app.php

'providers' => [
// Other Service Providers

'App\Providers\MyNewClassServiceProvider',
],
