Global Variable in Laravel 8

I am using Laravel 8. I need a Global variable which will be available in all Views (Blade files).

This Global variable will update using some API call with every route call.

How can I create this Global Variable ?

Solution

You can define your global variables in AppServiceProvider in boot method:

 public function boot()
    {
        $value = "myGlobal";
        View::share('key', $value);
    }
