# Architecture
|
||
|
|
|
||
|
|
core-template is the official starter template for building applications with the Core PHP Framework. It provides a pre-configured Laravel 12 application with the modular monolith architecture, Livewire 3, and Flux UI integration.
|
||
|
|
|
||
|
|
## Overview

|
|
## Bootstrap Process
|
||
|
|
|
||
|
|
The application bootstrap (`bootstrap/app.php`) registers Core PHP Framework providers:
|
||
|
|
|
||
|
|
```php
|
||
|
|
return Application::configure(basePath: dirname(__DIR__))
|
||
|
|
->withProviders([
|
||
|
|
\Core\LifecycleEventProvider::class, // Event system
|
||
|
|
\Core\Website\Boot::class, // Website components
|
||
|
|
\Core\Front\Boot::class, // Frontend (Livewire, Flux)
|
||
|
|
\Core\Mod\Boot::class, // Module discovery
|
||
|
|
])
|
||
|
|
->withRouting(...)
|
||
|
|
->withMiddleware(function (Middleware $middleware) {
|
||
|
|
\Core\Front\Boot::middleware($middleware);
|
||
|
|
})
|
||
|
|
->create();
|
||
|
|
```
|
||
|
|
|
||
|
|
### Provider Loading Order
|
||
|
|
|
||
|
|
1. **LifecycleEventProvider** - Sets up the event-driven architecture
|
||
|
|
2. **Website\Boot** - Registers website-level functionality
|
||
|
|
3. **Front\Boot** - Configures Livewire and frontend middleware
|
||
|
|
4. **Mod\Boot** - Discovers and loads modules from configured paths
|
||
|
|
|
||
|
|
## Module System
|
||
|
|
|
||
|
|
Modules are self-contained feature packages that register via lifecycle events. This is the core architectural pattern of the framework.
|
||
|
|
|
||
|
|
### Module Paths
|
||
|
|
|
||
|
|
Configured in `config/core.php`:
|
||
|
|
|
||
|
|
```php
|
||
|
|
'module_paths' => [
|
||
|
|
app_path('Core'), // Local framework overrides (EUPL-1.2)
|
||
|
|
app_path('Mod'), // Your application modules
|
||
|
|
app_path('Website'), // Website-specific code
|
||
|
|
],
|
||
|
|
```
|
||
|
|
|
||
|
|
### Module Structure
|
||
|
|
|
||
|
|
Each module lives in `app/Mod/{ModuleName}/` with a `Boot.php` entry point:
|
||
|
|
|
||
|
|
```
|
||
|
|
app/Mod/Blog/
|
||
|
|
├── Boot.php # Event listeners (required)
|
||
|
|
├── Models/
|
||
|
|
│ └── Post.php # Eloquent models
|
||
|
|
├── Routes/
|
||
|
|
│ ├── web.php # Web routes
|
||
|
|
│ └── api.php # API routes
|
||
|
|
├── Views/
|
||
|
|
│ └── posts/
|
||
|
|
│ └── index.blade.php
|
||
|
|
├── Livewire/
|
||
|
|
│ └── PostListPage.php # Livewire components
|
||
|
|
├── Migrations/
|
||
|
|
│ └── 2025_01_01_create_posts_table.php
|
||
|
|
└── Tests/
|
||
|
|
└── PostTest.php
|
||
|
|
```
|
||
|
|
|
||
|
|
### Boot.php Pattern
|
||
|
|
|
||
|
|
The `Boot.php` class declares which lifecycle events it responds to:
|
||
|
|
|
||
|
|
```php
|
||
|
|
<?php
|
||
|
|
|
||
|
|
declare(strict_types=1);
|
||
|
|
|
||
|
|
namespace App\Mod\Blog;
|
||
|
|
|
||
|
|
use Core\Events\WebRoutesRegistering;
|
||
|
|
use Core\Events\ApiRoutesRegistering;
|
||
|
|
use Core\Events\AdminPanelBooting;
|
||
|
|
use Core\Events\ConsoleBooting;
|
||
|
|
|
||
|
|
class Boot
|
||
|
|
{
|
||
|
|
/**
|
||
|
|
* Event listeners - class is only instantiated when events fire
|
||
|
|
*/
|
||
|
|
public static array $listens = [
|
||
|
|
WebRoutesRegistering::class => 'onWebRoutes',
|
||
|
|
ApiRoutesRegistering::class => 'onApiRoutes',
|
||
|
|
AdminPanelBooting::class => ['onAdminPanel', 10], // With priority
|
||
|
|
ConsoleBooting::class => 'onConsole',
|
||
|
|
];
|
||
|
|
|
||
|
|
public function onWebRoutes(WebRoutesRegistering $event): void
|
||
|
|
{
|
||
|
|
// Register routes
|
||
|
|
$event->routes(fn() => require __DIR__.'/Routes/web.php');
|
||
|
|
|
||
|
|
// Register view namespace (accessed as 'blog::view.name')
|
||
|
|
$event->views('blog', __DIR__.'/Views');
|
||
|
|
}
|
||
|
|
|
||
|
|
public function onApiRoutes(ApiRoutesRegistering $event): void
|
||
|
|
{
|
||
|
|
$event->routes(fn() => require __DIR__.'/Routes/api.php');
|
||
|
|
}
|
||
|
|
|
||
|
|
public function onAdminPanel(AdminPanelBooting $event): void
|
||
|
|
{
|
||
|
|
// Register admin navigation
|
||
|
|
$event->navigation('Blog', 'blog.admin.index', 'newspaper');
|
||
|
|
|
||
|
|
// Register admin resources
|
||
|
|
$event->resource('posts', PostResource::class);
|
||
|
|
}
|
||
|
|
|
||
|
|
public function onConsole(ConsoleBooting $event): void
|
||
|
|
{
|
||
|
|
// Register artisan commands
|
||
|
|
$event->commands([
|
||
|
|
ImportPostsCommand::class,
|
||
|
|
]);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Lifecycle Events
|
||
|
|
|
||
|
|
| Event | When Fired | Common Uses |
|
||
|
|
|-------|------------|-------------|
|
||
|
|
| `WebRoutesRegistering` | Web routes loading | Public routes, views |
|
||
|
|
| `ApiRoutesRegistering` | API routes loading | REST endpoints |
|
||
|
|
| `AdminPanelBooting` | Admin panel setup | Navigation, resources |
|
||
|
|
| `ClientRoutesRegistering` | Authenticated SaaS routes | Dashboard, settings |
|
||
|
|
| `ConsoleBooting` | Artisan bootstrapping | Commands, schedules |
|
||
|
|
| `McpToolsRegistering` | MCP server setup | AI agent tools |
|
||
|
|
|
||
|
|
### Lazy Loading
|
||
|
|
|
||
|
|
Modules are discovered at boot time, but their `Boot` classes are only instantiated when the events they listen to are fired. This means:
|
||
|
|
|
||
|
|
- Console commands don't load web routes
|
||
|
|
- API requests don't load admin panel code
|
||
|
|
- Unused modules have minimal overhead
|
||
|
|
|
||
|
|
## Dependency Packages
|
||
|
|
|
||
|
|
The template depends on four Core PHP Framework packages:
|
||
|
|
|
||
|
|
| Package | Namespace | Purpose |
|
||
|
|
|---------|-----------|---------|
|
||
|
|
| `host-uk/core` | `Core\` | Foundation: events, modules, lifecycle |
|
||
|
|
| `host-uk/core-admin` | `Core\Admin\` | Admin panel, Livewire modals, Flux UI |
|
||
|
|
| `host-uk/core-api` | `Core\Api\` | REST API, scopes, rate limiting, webhooks |
|
||
|
|
| `host-uk/core-mcp` | `Core\Mcp\` | Model Context Protocol for AI agents |
|
||
|
|
|
||
|
|
These are loaded as Composer dependencies and provide the framework infrastructure.
|
||
|
|
|
||
|
|
## Frontend Stack
|
||
|
|
|
||
|
|
### Livewire 3
|
||
|
|
|
||
|
|
Livewire components live within modules:
|
||
|
|
|
||
|
|
```php
|
||
|
|
// app/Mod/Blog/Livewire/PostListPage.php
|
||
|
|
<?php
|
||
|
|
|
||
|
|
declare(strict_types=1);
|
||
|
|
|
||
|
|
namespace App\Mod\Blog\Livewire;
|
||
|
|
|
||
|
|
use App\Mod\Blog\Models\Post;
|
||
|
|
use Illuminate\Contracts\View\View;
|
||
|
|
use Livewire\Component;
|
||
|
|
use Livewire\WithPagination;
|
||
|
|
|
||
|
|
class PostListPage extends Component
|
||
|
|
{
|
||
|
|
use WithPagination;
|
||
|
|
|
||
|
|
public function render(): View
|
||
|
|
{
|
||
|
|
return view('blog::posts.index', [
|
||
|
|
'posts' => Post::latest()->paginate(10),
|
||
|
|
]);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Flux UI
|
||
|
|
|
||
|
|
Flux Pro components are the standard UI library. Example usage:
|
||
|
|
|
||
|
|
```blade
|
||
|
|
<flux:modal name="edit-post">
|
||
|
|
<flux:heading>Edit Post</flux:heading>
|
||
|
|
<flux:input wire:model="title" label="Title" />
|
||
|
|
<flux:textarea wire:model="content" label="Content" />
|
||
|
|
<flux:button type="submit">Save</flux:button>
|
||
|
|
</flux:modal>
|
||
|
|
```
|
||
|
|
|
||
|
|
### Asset Pipeline
|
||
|
|
|
||
|
|
Vite handles asset compilation:
|
||
|
|
|
||
|
|
- `resources/css/app.css` - Tailwind CSS entry point
|
||
|
|
- `resources/js/app.js` - JavaScript entry point
|
||
|
|
- Module assets are not automatically included; import them in the main files or use `@vite` directive
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
### Core Framework (`config/core.php`)
|
||
|
|
|
||
|
|
```php
|
||
|
|
return [
|
||
|
|
// Paths to scan for modules
|
||
|
|
'module_paths' => [
|
||
|
|
app_path('Core'),
|
||
|
|
app_path('Mod'),
|
||
|
|
app_path('Website'),
|
||
|
|
],
|
||
|
|
|
||
|
|
// Service configuration
|
||
|
|
'services' => [
|
||
|
|
'cache_discovery' => env('CORE_CACHE_DISCOVERY', true),
|
||
|
|
],
|
||
|
|
|
||
|
|
// CDN configuration
|
||
|
|
'cdn' => [
|
||
|
|
'enabled' => env('CDN_ENABLED', false),
|
||
|
|
'driver' => env('CDN_DRIVER', 'bunny'),
|
||
|
|
],
|
||
|
|
];
|
||
|
|
```
|
||
|
|
|
||
|
|
### Environment Variables
|
||
|
|
|
||
|
|
Key Core-specific environment variables:
|
||
|
|
|
||
|
|
| Variable | Default | Description |
|
||
|
|
|----------|---------|-------------|
|
||
|
|
| `CORE_CACHE_DISCOVERY` | `true` | Cache module discovery for performance |
|
||
|
|
| `CDN_ENABLED` | `false` | Enable CDN for static assets |
|
||
|
|
| `CDN_DRIVER` | `bunny` | CDN provider (bunny, cloudflare, etc.) |
|
||
|
|
| `FLUX_LICENSE_KEY` | - | Flux Pro license key (optional) |
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
|
||
|
|
Tests use Pest PHP and follow Laravel conventions:
|
||
|
|
|
||
|
|
```php
|
||
|
|
// tests/Feature/BlogTest.php
|
||
|
|
<?php
|
||
|
|
|
||
|
|
use App\Mod\Blog\Models\Post;
|
||
|
|
|
||
|
|
it('displays posts on the index page', function () {
|
||
|
|
$posts = Post::factory()->count(3)->create();
|
||
|
|
|
||
|
|
$this->get('/blog')
|
||
|
|
->assertOk()
|
||
|
|
->assertSee($posts->first()->title);
|
||
|
|
});
|
||
|
|
|
||
|
|
it('requires authentication to create posts', function () {
|
||
|
|
$this->post('/blog', ['title' => 'Test'])
|
||
|
|
->assertRedirect('/login');
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### Test Organisation
|
||
|
|
|
||
|
|
- **Feature tests** - HTTP requests, Livewire components, integration tests
|
||
|
|
- **Unit tests** - Services, utilities, isolated logic
|
||
|
|
- **Module tests** - Can live within the module directory (`app/Mod/Blog/Tests/`)
|
||
|
|
|
||
|
|
## Routing
|
||
|
|
|
||
|
|
### Route Registration
|
||
|
|
|
||
|
|
Routes are registered via module events, not the traditional `routes/` directory:
|
||
|
|
|
||
|
|
```php
|
||
|
|
// app/Mod/Blog/Routes/web.php
|
||
|
|
<?php
|
||
|
|
|
||
|
|
use App\Mod\Blog\Livewire\PostListPage;
|
||
|
|
use App\Mod\Blog\Livewire\PostShowPage;
|
||
|
|
use Illuminate\Support\Facades\Route;
|
||
|
|
|
||
|
|
Route::prefix('blog')->name('blog.')->group(function () {
|
||
|
|
Route::get('/', PostListPage::class)->name('index');
|
||
|
|
Route::get('/{post:slug}', PostShowPage::class)->name('show');
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
The `routes/web.php` and `routes/api.php` files are fallbacks for routes that don't belong to any module.
|
||
|
|
|
||
|
|
### View Namespacing
|
||
|
|
|
||
|
|
Module views are namespaced:
|
||
|
|
|
||
|
|
```blade
|
||
|
|
{{-- Accessing blog module views --}}
|
||
|
|
@include('blog::partials.header')
|
||
|
|
|
||
|
|
{{-- In a Livewire component --}}
|
||
|
|
return view('blog::posts.index', [...]);
|
||
|
|
```
|
||
|
|
|
||
|
|
## Namespace Conventions
|
||
|
|
|
||
|
|
| Path | Namespace | License |
|
||
|
|
|------|-----------|---------|
|
||
|
|
| `app/Core/` | `Core\` (local) | EUPL-1.2 |
|
||
|
|
| `app/Mod/` | `App\Mod\` | Your choice |
|
||
|
|
| `app/Website/` | `App\Website\` | Your choice |
|
||
|
|
| `vendor/host-uk/core/` | `Core\` | EUPL-1.2 |
|
||
|
|
|
||
|
|
The `app/Core/` directory is for local overrides of framework classes. Any class you place here will take precedence over the vendor package.
|
