Avoid Dependency Recursion

Here's a quick tip. If you have embraced the repository pattern for your Laravel application, you may have run into a 502 bad gateway. This can happen if you choose to setup the constructors of one or more repositories to mutually direct inject each other. The result is a loop or recursion of the dependencies between the objects being direct injected.

class CurrentRepository
{
    protected $others;

    public function __construct(OtherRepository $others)
    {
        $this->others = $others;
    }
}

If you have pulled out your hair with this before, here's the tip. Instead, you can app() or app()->make() the repositories you need access to within a protected function and avoid the injection loop altogether.

// Now you can access the other repository within 
// the current repository with $this->others()
protected function others() 
{
    return app(OtherRepository::class);
}

Please note, if your object dependencies are looping, you may want to restructure your code so that the repositories stop depending on each other altogether.
