Atomic Framework App Auth

Atomic Framework App and Auth

When to Use

• Writing controllers, page controllers, or app models.
• Implementing login, logout, Google OAuth, or Telegram login.
• Checking auth state, roles, or session lifetime.
• Working with app-level storage, system state, or plugin wiring.

Controller

namespace App\Http\Controllers;

use Engine\Atomic\App\Controller;

final class Posts extends Controller
{
    public function index(\Base $f3): void
    {
        $posts = (new \App\Models\Post())->find();
        $f3->set('posts', $posts);
        echo \Template::instance()->render('posts/index.htm');
    }

    public function store(\Base $f3): void
    {
        $post = new \App\Models\Post();
        $post->title = $f3->get('POST.title');

        if (!$post->save()) {
            [$code, $vars] = $post->get_last_err_data();
            send_json_error('Validation failed', 422, ['code' => $code]);
            return;
        }

        send_json(['id' => $post->id]);
    }
}

Page Controller

Engine\Atomic\App\Page is used for rendering theme-based pages (head, body, title, meta).

Model (App\Model)

See atomic-framework-data skill for full Model API.

use Engine\Atomic\App\Model;

final class Post extends Model
{
    protected $table = 'posts';
    protected $fieldConf = [
        'title' => ['type' => 'VARCHAR256', 'nullable' => false],
    ];
}

App Models

• Engine\Atomic\App\Models\Options -- app-wide key-value store (global config at APP_UUID scope)
• Engine\Atomic\App\Models\Meta -- per-entity metadata keyed by UUID + key
• Engine\Atomic\App\Models\MutexLock -- DB-backed mutex lock records

Options (global app config)

use Engine\Atomic\App\Models\Options;

Options::set_option('site_name', 'My Store');
Options::set_option('session_ttl', '3600', ttl: 86400); // with TTL (seconds); 0 = no expiry
$name = Options::get_option('site_name');          // mixed|false (returns $default if not found)
$name = Options::get_option('site_name', 'Shop');  // with default
Options::delete_option('site_name');

// has_option: returns [timestamp, ttl] or false; populates $val by reference
$result = Options::has_option('site_name', $val);
if ($result !== false) {
    [$ts, $ttl] = $result;   // $val contains the stored value
}

// Pattern queries (LIKE, e.g. 'cache_%')
$map = Options::get_option_like('cache_%');         // ['cache_posts' => '...', ...]
Options::delete_option_like('temp_%');              // bool

// Global helpers
add_option('site_name', 'My Store');
update_option('site_name', 'New Name');
$name = get_option('site_name', 'Default');
delete_option('site_name');

Meta (per-entity metadata)

use Engine\Atomic\App\Models\Meta;

Meta::set_meta($userUuid, 'profile_pic', '/avatars/1.jpg');
$pic = Meta::get_meta($userUuid, 'profile_pic');
$ok  = Meta::has_meta($userUuid, 'profile_pic');  // bool
Meta::delete_meta($userUuid, 'profile_pic');

// Pattern match (LIKE)
$all = Meta::get_meta_like($userUuid, 'upload_%');   // array|false
Meta::delete_meta_like($userUuid, 'upload_%');       // bool

// Global helpers
add_meta($uuid, 'key', 'value');
update_meta($uuid, 'key', 'value');
$val = get_meta($uuid, 'key');
delete_meta($uuid, 'key');

Storage (abstract base)

Engine\Atomic\App\Storage is the base class for Options and Meta. It provides _set, _get, _has, _delete, _get_like, _delete_like as protected static methods keyed by uuid + key. Extend it to build custom per-entity stores.

Page (CMS Model)

Engine\Atomic\App\Page extends Model and provides a rich pre-configured field set for CMS-style content:

namespace App\Models;

use Engine\Atomic\App\Page;

final class Article extends Page
{
    protected $table = 'articles';

    // Optionally declare relations
    protected static function category_model(): ?string
    {
        return Category::class;    // auto-adds belongs-to-one 'category'
    }

    protected static function author_model(): ?string
    {
        return \App\Models\User::class;  // auto-adds belongs-to-one 'author'
    }
}

Built-in fields (pre-configured, no need to declare):

User Role Helpers

// Auth helpers
atomic_get_current_user();              // ?AuthenticatableInterface
is_authenticated();                     // bool
is_guest();                             // bool
has_role(Role::ADMIN);                  // bool
has_role('admin');                      // accepts string or BackedEnum
has_any_role([Role::ADMIN, Role::SELLER]);  // bool (any of)

// Short-hand role checkers (from helpers.php)
is_admin();
is_seller();
is_buyer();
is_support();
// Note: no is_moderator() helper exists; use has_role(Role::MODERATOR) directly

// Impersonation (admin acting as another user)
is_impersonating();    // bool
get_real_admin();      // ?AuthenticatableInterface

Auth Facade

Engine\Atomic\Auth\Auth is the main auth entry point.

use Engine\Atomic\Auth\Auth;

$auth = Auth::instance();
$user = $auth->get_current_user();      // ?AuthenticatableInterface
$auth->logout();

// Login by ID (bypass credentials -- for impersonation or trusted flows)
$auth->login_by_id('user-uuid');

// Login with secret key (e.g. API key auth)
$user = $auth->login_with_secret(['email' => 'a@b.com'], $secret);

// Rate limiting (returns false if limit exceeded)
$ok = $auth->check_rate_limit(['email' => 'a@b.com'], 'register');

// Impersonation
$auth->impersonate_user('target-user-uuid');  // bool
$auth->stop_impersonation();                  // bool
$auth->is_impersonating();                    // bool
$auth->get_real_admin();                      // ?AuthenticatableInterface

Session Facade

use Engine\Atomic\Auth\Session;

Session::init();
Session::start();
Session::start('550e8400-e29b-41d4-a716-446655440000'); // resume by ID

if (Session::is_started()) { /* ... */ }
if (Session::is_expired()) { /* ... */ }
Session::destroy();

Session data lives in the F3 hive:

$f3 = \Base::instance();
$f3->set('SESSION.user_uuid', '550e...');
$uuid = $f3->get('SESSION.user_uuid');
$f3->clear('SESSION.user_uuid');

Session Manager (Storage Inspection)

use Engine\Atomic\Session\SessionManager;

$manager = new SessionManager();           // auto-selects driver
$redis   = new SessionManager('redis');
$sql     = new SessionManager('database');

$exists = $manager->session_exists($session_id);
$data   = $manager->get_session_data($session_id);
$manager->delete_session($session_id);
$manager->delete_sessions([$id1, $id2]);

Drivers: database (SQL via SqlSessionTrait) or redis (via RedisSessionTrait).

Google Auth

Engine\Atomic\Auth\GoogleAuth + GoogleAuthService + GoogleClientAdapter.

use Engine\Atomic\Auth\GoogleAuth;
use Engine\Atomic\Auth\Interfaces\OAuthUserResolverInterface;

$google = GoogleAuth::instance();

if (!$google->is_configured()) {
    throw new \RuntimeException('Google OAuth not configured');
}

// Step 1: redirect to Google
$loginUrl = $google->get_login_url();
\Base::instance()->reroute($loginUrl);

// Step 2: handle callback (routes/web.php)
// $google->set_user_resolver(new MyUserResolver());
$redirectUrl = $google->handle_callback($code, $state);  // ?string
// Returns redirect URL or null on failure

Required config keys (in .env / config/auth.php): GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_CALLBACK_URL.

Telegram Auth

Engine\Atomic\Auth\TelegramAuth + TelegramAuthService + TelegramClientAdapter.

use Engine\Atomic\Auth\TelegramAuth;

$tg = TelegramAuth::instance();

if (!$tg->is_configured()) {
    throw new \RuntimeException('Telegram auth not configured');
}

// Render Telegram Login Widget -- get HTML attributes
$attrs = $tg->get_widget_attributes(
    size: 'large',          // 'small', 'medium', 'large'
    request_access: false,  // request write access
    use_avatar: true,
    corner_radius: 12,
);
// $attrs = ['data-telegram-login' => '...', 'data-size' => 'large', ...]

// Verify and handle callback (POST with auth data from widget)
$authData = $_POST; // or from JSON body
$verified = $tg->verify_auth_data($authData); // array|false
if ($verified !== false) {
    $redirectUrl = $tg->handle_callback($verified); // ?string
}

// Meta
$tg->get_bot_username();    // string
$tg->get_callback_url();    // string

Required config keys: TELEGRAM_BOT_TOKEN, TELEGRAM_CALLBACK_URL.

Auth Interfaces

Guardrails

• Never store passwords in session or plaintext. Use BcryptHasherAdapter.
• Always check HasRolesInterface before calling Guard::has_role().
• Use Session::destroy() on logout, not raw session_destroy().
• Keep adapters thin; business logic belongs in services.
