When you did $this->app->bind(), you've bound an instance of a class to the IoC. When you bind to the IoC you make that available throughout the entirety of the application. HOWEVER:
Your namespaces break PSR-1 compliance. This is because you are not using StudlyCaps.
BAD: use App\Helpers\api\gg\gg
GOOD: use App\Helpers\Api\GG\GG.
Rename your folders/files accordingly. With that sorted, your bind function should actually change to a singleton. This is because you want a persistent state, not a reusable model.
$this->app->singleton(GG::class, function(){
return new GG;
});
You also should not check ->isReady() in every function, that's an example of an anti-pattern. Instead, this should be in a middleware:
php artisan make:middleware VerifyGGReady
Add this to your Kernel:
protected $routeMiddleware = [
//other definitions
'gg_ready' => App\Http\Middleware\VerifyGGReady::class
];
Update the handle() function in your middleware:
public function handle($request, Closure $next) {
if ($this->app->GG->isReady()) {
return $next($request);
}
return redirect('/'); //gg is not ready
});
And then either initialize it in your route groups:
Route::group(['middleware' => ['gg_ready']], function(){
//requires GG to be ready
});
Or directly on a route:
Route::get('acme', 'AcmeController#factory')->middleware('gg_ready');
Or use it in your controller:
$this->middleware('gg_ready');
