Laravel Settings Kit

A Laravel package for managing global and user-specific settings with multilingual support, built-in caching, and a full REST API.

Features

• Two-level settings. Global defaults with per-user overrides. Users who haven't customised a setting automatically inherit the global default, with no extra queries.
• Type casting. Values are stored as strings and automatically cast to boolean, integer, json, select, or string on retrieval.
• Built-in cache. Every read is cached. Changing a global default is immediately visible to all users who haven't customised it.
• Batch operations. Update multiple settings in a single call. Retrieve all settings for a user, or only the ones they've personalised.
• Multilingual labels. Attach translated titles and descriptions to settings, with locale fallback.
• Role-based visibility. Tag settings with a role to control which users see them.
• REST API. Full API for SPAs, mobile apps, and headless applications, with token, Sanctum, and Passport authentication.
• Events. A SettingUpdated event is dispatched on every write and reset, for audit logs and side effects.
• Blade directive. @setting('key') renders a setting value directly in templates.
• Artisan commands. settings:list, settings:export, settings:import, settings:clear-cache.

Requirements

PHP 8.1 or higher, Laravel 9 or higher.

Installation

composer require metalinked/laravel-settings-kit

php artisan vendor:publish --provider="Metalinked\LaravelSettingsKit\SettingsKitServiceProvider" --tag="migrations"
php artisan migrate

Publish the config file (optional):

php artisan vendor:publish --provider="Metalinked\LaravelSettingsKit\SettingsKitServiceProvider" --tag="config"

Basic Usage

use Metalinked\LaravelSettingsKit\Facades\Settings;

// Read a global setting
$value = Settings::get('site_name');

// Read a user-specific setting (falls back to the global default if not customised)
$theme = Settings::get('theme', $userId);

// Write a global setting (the preference must exist in the database)
Settings::set('site_name', 'My App');

// Write a user-specific setting
Settings::set('theme', 'dark', $userId);

// Write and auto-create the preference if it does not exist yet
Settings::setWithAutoCreate('new_feature_enabled', true);

// Get or auto-create with a default value
$perPage = Settings::remember('items_per_page', 20);

// Check a boolean setting
if (Settings::isEnabled('maintenance_mode')) {
    abort(503);
}

// Read multiple settings in a single query
$settings = Settings::getMultiple(['theme', 'language', 'timezone'], $userId);

// Update multiple settings in a single call
Settings::setMultiple(['theme' => 'dark', 'language' => 'ca'], $userId);

// Reset a user's customisation, reverting to the global default
Settings::forget('theme', $userId);

// Reset all of a user's customisations at once
$count = Settings::forgetAll($userId);

// Permanently delete a preference and all its user customisations
Settings::delete('old_feature_flag');

Auto-creation and type detection

setWithAutoCreate() creates the preference automatically if it does not exist, detecting the type from the PHP value:

Settings::setWithAutoCreate('maintenance_mode', false); // boolean
Settings::setWithAutoCreate('max_users', 100);          // integer
Settings::setWithAutoCreate('theme_config', ['dark' => true]); // json
Settings::setWithAutoCreate('site_name', 'My App');     // string

Predefined settings (recommended)

For production use, create settings upfront via a seeder so you have full control over type, defaults, and constraints:

use Metalinked\LaravelSettingsKit\Models\Preference;

Preference::firstOrCreate(['key' => 'maintenance_mode'], [
    'type' => 'boolean',
    'default_value' => '0',
    'category' => 'system',
    'is_user_customizable' => false,
]);

Preference::firstOrCreate(['key' => 'theme'], [
    'type' => 'select',
    'default_value' => 'light',
    'options' => ['light', 'dark', 'auto'],
    'category' => 'appearance',
    'is_user_customizable' => true,
]);

Values for select settings are validated on write: passing a value not in options throws an InvalidArgumentException.

Global vs. User Settings

The package distinguishes two types of settings based on the is_user_customizable column.

Global unique settings (is_user_customizable = false) apply to the entire application. Calling Settings::set('maintenance_mode', true) updates default_value directly and affects everyone immediately.

User-customisable settings (is_user_customizable = true) have a global default that individual users can override. The global default lives in preferences.default_value. Per-user overrides are stored in user_preferences only when the user actually changes the value, keeping the table lean.

// Change the global default (affects all users who have not customised)
Settings::set('theme', 'dark');

// User 123 sets a personal preference (stored in user_preferences)
Settings::set('theme', 'custom', 123);

Settings::get('theme');       // 'dark'  (global default)
Settings::get('theme', 123);  // 'custom' (user override)
Settings::get('theme', 456);  // 'dark'  (inherits global default)

Loading all settings for a user

allForUser() is designed for app boot: one query fetches all customisable settings with resolved values and an is_overridden flag showing whether the user has personalised each one.

$settings = Settings::allForUser($userId, locale: 'ca');
// [
//   'theme' => ['value' => 'dark', 'is_overridden' => true,  'type' => 'select', ...],
//   'language' => ['value' => 'en',   'is_overridden' => false, 'type' => 'string', ...],
// ]

To retrieve only the settings a user has explicitly overridden:

$overrides = Settings::getUserOverrides($userId);
// ['theme' => 'dark']  (only the keys with a personal override)

Multilingual Labels

Settings::createWithTranslations('notification_email', [
    'type' => 'boolean',
    'default_value' => '1',
    'category' => 'notifications',
], [
    'en' => ['title' => 'Email Notifications', 'text' => 'Receive notifications via email'],
    'es' => ['title' => 'Notificaciones por Email', 'text' => 'Recibir notificaciones por correo'],
    'ca' => ['title' => 'Notificacions per Email', 'text' => 'Rebre notificacions per correu'],
]);

// Retrieve translated labels (falls back to the configured fallback_locale if missing)
Settings::label('notification_email', 'ca');       // 'Notificacions per Email'
Settings::description('notification_email', 'fr'); // fallback to 'en'

// Add translations to an existing setting
Settings::addTranslations('theme', [
    'en' => ['title' => 'Theme', 'text' => 'Choose your preferred theme'],
    'es' => ['title' => 'Tema', 'text' => 'Elige tu tema preferido'],
]);

// Get all settings with translated labels for a locale
$settings = Settings::allWithTranslations('ca');

Events

A SettingUpdated event is dispatched after every set() and forget() call:

use Metalinked\LaravelSettingsKit\Events\SettingUpdated;

Event::listen(SettingUpdated::class, function (SettingUpdated $event) {
    // $event->key, $event->value (null on forget/reset), $event->userId
    Log::info("Setting '{$event->key}' changed", ['value' => $event->value, 'user' => $event->userId]);
});

Blade Directive

<title>@setting('site_name')</title>
<body class="theme-@setting('theme', auth()->id())">

Artisan Commands

# List all settings
php artisan settings:list
php artisan settings:list --category=system
php artisan settings:list --type=boolean

# Export to JSON
php artisan settings:export
php artisan settings:export --file=settings.json --category=system

# Import from JSON
php artisan settings:import settings.json
php artisan settings:import settings.json --force      # overwrite existing
php artisan settings:import settings.json --dry-run    # preview only

# Clear the settings cache (works with any cache driver)
php artisan settings:clear-cache

REST API

Enable the API in your .env:

SETTINGS_KIT_API_ENABLED=true
SETTINGS_KIT_API_AUTH=token
SETTINGS_KIT_API_TOKEN=your-secure-token

For local development, you can bypass authentication entirely:

SETTINGS_KIT_API_ENABLED=true
SETTINGS_KIT_API_DISABLE_AUTH_DEV=true

Authentication

Note: Token mode grants full access to all users' settings. Use Sanctum or Passport for user-facing APIs where each user should only access their own settings.

Batch update example
