# Architecture
> Generated: 2026-04-26
## Overview
cmsPRO uses a **3-layer architecture** with clean admin/frontend separation:
```
Request
Controls (admin\controls\ or front\controls\) ← request handling
Factories (admin\factory\ or front\factory\) ← DEPRECATED wrappers → will be removed
Domain Repositories (Domain\*\*Repository) ← data access (new pattern)
Medoo ORM → MySQL
```
Views are rendered through `admin\view\*` / `front\view\*``Shared\Tpl\Tpl` → Savant3 templates.

## Namespace Convention
| Namespace | Path | Convention |
|-----------|------|-----------|
| `admin\controls\` | `autoload/admin/controls/class.*.php` | Legacy lowercase |
| `admin\factory\` | `autoload/admin/factory/class.*.php` | Legacy, @deprecated |
| `admin\view\` | `autoload/admin/view/class.*.php` | Legacy lowercase |
| `front\controls\` | `autoload/front/controls/class.*.php` | Legacy lowercase |
| `front\factory\` | `autoload/front/factory/class.*.php` | Legacy lowercase |
| `Domain\*\` | `autoload/Domain/*/ClassName.php` | PSR-4 PascalCase |
| `Shared\*\` | `autoload/Shared/*/ClassName.php` | PSR-4 PascalCase |
## Key Patterns
### Repository Pattern (Domain layer)
```php
class ArticlesRepository {
public function __construct($db) { $this->db = $db; }
public function find(int $id): ?array { ... }
public function save(...): int { ... }
}
```
### Factory Wrapper (deprecated bridge)
```php
/** @deprecated Używaj Domain\Articles\ArticlesRepository przez DI */
class Articles {
private static function repo(): ArticlesRepository {
global $mdb;
return new ArticlesRepository($mdb);
}
public static function article_delete($id): bool {
return self::repo()->deleteArticle($id);
}
}
```
### Controls (request handler)
```php
class Articles {
public static function article_delete() {
global $user;
if (!admin\factory\Users::check_privileges('articles', $user['id']))
return \S::alert('Brak uprawnień');
// delegate to factory → repository
}
}
```
### Global Helper Facade
```php
// class.S.php — calls Shared\Helpers\Helpers via __callStatic
\S::get('param') // → Helpers::get()
\S::delete_cache() // → Helpers::delete_cache()
```
## Admin Routing
`GET /admin/?a=articles&action=view_list``admin\controls\Articles::view_list()`
Routing in `admin/index.php`: reads `$_GET['a']` → dynamically loads control class → calls action method.
## Frontend Routing
`index.php``front\controls\Site::route()` — checks `\S::get('search')`, `\S::get('tag')`, `\S::get('article')`, then falls through to page rendering by `page_type`.
## Caching Strategy
| Cache Type | Location | Engine |
|-----------|----------|--------|
| Page cache | `cache/` | Full HTML output |
| Object cache | `temp/md5[0]/md5[1]/` | gzdeflate + serialize, TTL |
| WebP images | `cache/` | Filesystem |
| Language strings | `$_SESSION` | PHP session |
## Plugin System
3 hook points in frontend lifecycle (files in `plugins/` directory, included if they exist):
1. `special-actions.php` — after language init, before routing
2. `special-actions-middle.php` — before cache check
3. `special-actions-end.php` — before final output
