Understanding configuration management is essential for Laravel developers to build secure, maintainable, and scalable applications.

1

Create a configuration file

Create a configuration file named appsettings.php inside the config folder with these exact entries: 'mode' => 'development', 'feature_enabled' => false.

Laravel

<?php

return [
    // Your code here
];

Need a hint?

Configuration files in Laravel return an array of key-value pairs.

2

Add environment variable

Add an environment variable named APP_MODE with the value production in the .env file.

Laravel

# Add the line 'APP_MODE=production' to the .env file
# Your code here

Need a hint?

The .env file holds environment-specific variables for Laravel.

3

Use configuration in a controller

In a controller named ConfigController, write a method showConfig that gets the mode value from the appsettings config file using config('appsettings.mode') and stores it in a variable called $mode.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ConfigController extends Controller
{
    public function showConfig()
    {
        // Your code here
    }
}

Need a hint?

Use the config() helper to access configuration values.

4

Return configuration in response

Complete the showConfig method to return a JSON response with a key current_mode and the value of the $mode variable using return response()->json(['current_mode' => $mode]);.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ConfigController extends Controller
{
    public function showConfig()
    {
        $mode = config('appsettings.mode');
        // Return JSON response here
    }
}

Need a hint?

Use Laravel's response()->json() to send JSON data.
