Laravel 6 - Conditionally enable debug page on production mode - laravel

Question

I used to run debug true in production when needed with Laravel 5 the following way:
'debug' => env('APP_DEBUG', $_SERVER['REMOTE_ADDR'] == 'myipaddress' ? true : false),
However Laravel 6 doesn't let me use it, when I do artisan config:cache, artisan complains that:
variable $_server['REMOTE_ADDR'] is not defined and exists.
Is there another way someone has found out to be working to do this with Laravel 6?

You can't cache dynamic configs. there is no request and no $_server when Laravel tries to cache your configs.
You must disable your debug on production (APP_DEBUG = false) and check the log for any errors.
But if you insist to enable app debug dynamically, you can use middleware:
Create a new middleware using Artisan command:
php artisan make:middleware EnableDebug
This command will place a new EnableDebug class within your app/Http/Middleware directory. Modify it like this:
<?php
namespace App\Http\Middleware;
use Closure;
class EnableDebug
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
config(['app.debug' => $request->ip() === 'myipaddress']);
return $next($request);
}
}
List your middleware class at the end of the $middleware property of your app/Http/Kernel.php class:
protected $middleware = [
//...
\App\Http\Middleware\EnableDebug::class,
];
