Pelican Panel Plugins

Pelican is an open-source game server management panel built on Laravel + FilamentPHP. Plugins let you add functionality without touching core files.

⚠️ The plugin system is still in active development — some features may change.

Quick Reference

📖 Detailed Guides:

• FilamentPHP Patterns - Resources, pages, widgets, actions, relation managers
• Advanced Patterns - Models, services, routes, commands, events
• Complete Plugin Walkthrough - Step-by-step example

Scaffolding a New Plugin

Run inside the panel directory (

/var/www/pelican

php artisan p:plugin:make

This creates the basic structure with

plugin.json

Critical: The plugin folder name must exactly match the

id

field in

plugin.json

.

Main Plugin Class

Located in

src/{ClassName}.php

namespace MyName\MyPlugin;

use Filament\Contracts\Plugin;
use Filament\Panel;

class MyPlugin implements Plugin
{
    public function getId(): string
    {
        return 'my-plugin';
    }

    public function register(Panel $panel): void
    {
        $id = str($panel->getId())->title(); // "Admin", "App", "Server"

        // Auto-discover Filament components
        $panel->discoverPages(
            plugin_path($this->getId(), "src/Filament/$id/Pages"),
            "MyName\\MyPlugin\\Filament\\$id\\Pages"
        );
        $panel->discoverResources(
            plugin_path($this->getId(), "src/Filament/$id/Resources"),
            "MyName\\MyPlugin\\Filament\\$id\\Resources"
        );
        $panel->discoverWidgets(
            plugin_path($this->getId(), "src/Filament/$id/Widgets"),
            "MyName\\MyPlugin\\Filament\\$id\\Widgets"
        );
    }

    public function boot(Panel $panel): void
    {
        //
    }
}

The Three Filament Panels

admin

app

server

Enabling Navigation on

app

Panel

use App\Filament\App\Resources\Servers\ServerResource;
use App\Enums\CustomizationKey;

public function register(Panel $panel): void
{
    parent::register($panel);

    if ($panel->getId() === 'app') {
        ServerResource::embedServerList();
        $panel->navigation(true);
        $panel->topbar(function () {
            $nav = user()?->getCustomization(CustomizationKey::TopNavigation);
            return in_array($nav, ['topbar', 'mixed', true], true);
        });
        $panel->clearCachedComponents();
    }
}

Extending Core Resources

Call static methods on core classes inside a service provider's

register()

use App\Filament\Admin\Resources\Users\UserResource;
use App\Filament\Admin\Resources\Servers\ServerResource;
use App\Models\Role;

public function register(): void
{
    // Add a relation manager tab
    ServerResource::registerCustomRelations(MyRelationManager::class);
    
    // Register permissions
    Role::registerCustomDefaultPermissions('myModel');
    Role::registerCustomModelIcon('myModel', 'tabler-star');
}

Available customization traits (check

app/Traits/Filament/

• CanModifyResource

  - Relation managers, custom actions

• CanCustomizePage

  - Widgets, header actions

• CanModifyForm

  /

  CanModifyTable

  - Form/table hooks

Plugin Settings

Implement

HasPluginSettings

use App\Contracts\Plugins\HasPluginSettings;
use App\Traits\EnvironmentWriterTrait;
use Filament\Forms\Components\TextInput;
use Filament\Notifications\Notification;

class MyPlugin implements Plugin, HasPluginSettings
{
    use EnvironmentWriterTrait;

    public function getSettingsForm(): array
    {
        return [
            TextInput::make('api_key')
                ->required()
                ->default(fn () => config('my-plugin.api_key')),
        ];
    }

    public function saveSettings(array $data): void
    {
        $this->writeToEnvironment([
            'MY_PLUGIN_API_KEY' => $data['api_key'],
        ]);

        Notification::make()->title('Settings saved')->success()->send();
    }
}

Always prefix env vars with your plugin ID to avoid conflicts.

Permissions

Admin Role Permissions

In your service provider's

register()

use App\Models\Role;

// Shorthand: registers viewList, view, create, update, delete
Role::registerCustomDefaultPermissions('myModel');

// Custom permissions
Role::registerCustomPermissions([
    'myModel' => ['export', 'approve'],
    'server'  => ['customAction'], // extend existing model
]);

// Optional: icon for permission group
Role::registerCustomModelIcon('myModel', 'tabler-star');

Subuser Permissions

use App\Models\Subuser;

// New permission group
Subuser::registerCustomPermissions('myFeature', ['read', 'write'], 'tabler-bolt', false);

// Append to existing group
Subuser::registerCustomPermissions('console', ['myCustomAction']);

Routes

Create a

RouteServiceProvider

src/Providers/

use Illuminate\Foundation\Support\Providers\RouteServiceProvider;
use Illuminate\Support\Facades\Route;

class MyPluginRoutesProvider extends RouteServiceProvider
{
    public function boot(): void
    {
        $this->routes(function () {
            // Simple route
            Route::get('/my-plugin/test', [TestController::class, 'index'])
                ->name('my-plugin.test');

            // Load from file
            Route::prefix('/my-plugin')
                ->group(plugin_path('my-plugin', 'routes/web.php'));

            // Append to client API
            Route::middleware(['api', 'client-api', 'throttle:api.client'])
                ->prefix('/api/client/servers/{server}')
                ->scopeBindings()
                ->group(plugin_path('my-plugin', 'routes/api-client.php'));
        });
    }
}

Models & Relationships

Add Relationship to Core Models

In your service provider's

boot()

use App\Models\Server;
use MyPlugin\Models\Ticket;

public function boot(): void
{
    Server::resolveRelationUsing('tickets', fn (Server $server) => 
        $server->hasMany(Ticket::class, 'server_id', 'id')
    );
}

Now

$server->tickets

Policies

use App\Policies\DefaultAdminPolicies;

class MyModelPolicy
{
    use DefaultAdminPolicies;
    
    protected string $modelName = 'myModel';
}

This automatically checks admin role permissions based on the registered model name.

Translations

Place in

lang/{locale}/

lang/en/strings.php

return [
    'welcome' => 'Welcome',
    'item' => 'Item|Items', // Pluralization
];

Usage:

trans('my-plugin::strings.welcome')
trans_choice('my-plugin::strings.item', 2) // "Items"

Views

Place in

resources/views/

view('my-plugin::my-view')
// → plugins/my-plugin/resources/views/my-view.blade.php

Common Patterns

FilamentPHP Components

See FilamentPHP Patterns for:

• Resources (CRUD interfaces)
• Pages (custom pages)
• Widgets (dashboard components)
• Relation Managers (manage related records)
• Custom Actions (reusable buttons)
• Form components (inputs, selects, toggles)
• Table columns and filters

Advanced Patterns

See Advanced Patterns for:

• Model events and hooks
• Enums with Filament interfaces
• Service classes
• HTTP controllers and API routes
• Artisan commands and scheduling
• HTTP macros for external APIs
• Database migrations
• Error handling

Complete Example

See Complete Plugin Walkthrough for a step-by-step guide building a "Server Notes" plugin.

Publishing a Plugin

1. Open

   plugin.json

   and remove the

   meta

   block (internal use only)
2. Zip the entire plugin folder
3. Share the zip — users install via panel UI Import button or manually drop into

   plugins/

Publish to the community:

• GitHub: pelican-dev/plugins
• Discord:

  #plugins

  channel at discord.gg/pelican-panel

Tips & Gotchas

• Namespace in plugin.json: Use

  \\

  (double backslash) for namespace separators
• Migration naming: Use numeric prefixes (

  001_

  ,

  002_

  ) to control execution order
• Environment variables: Always prefix with your plugin ID (e.g.,

  MY_PLUGIN_*

  )
• Panel context: Use

  Filament::getTenant()

  to get current server in server panel
• Auto-discovery: Service providers, commands, migrations, and policies are auto-discovered
• Relation managers: Must be registered on core resources via

  registerCustomRelations()

  in service provider's

  register()

  method
• Testing: Use

  php artisan migrate:fresh --seed

  to reset and test migrations
• Permissions: Register in service provider's

  register()

  , not

  boot()
