Rudra Framework

A lightweight, transparent PHP framework built on the principles of simplicity and clarity.

~15 MB · Lightweight Query Builder · No hidden dependencies · No magic · PHP 8.3 Attributes · Porto Architecture

Philosophy

Rudra follows the KISS principle — every tool is visible, every dependency is explicit, and every layer does exactly one thing. No "magic" happens behind the scenes: if you see it in the code, that's all there is.

• Transparency — no hidden behavior, no implicit side effects
• Simplicity — minimal surface area, easy to learn and extend
• Explicit over implicit — dependencies are declared, not guessed
• Modern PHP — built from the ground up on PHP 8.3+ features (attributes, typed constants, fibers)

Who is this for?

Rudra is built for developers who:

• Prefer explicit code over framework magic — you want to see exactly what SQL is executed, what routes are registered, and what dependencies are injected
• Value cognitive clarity — you need a framework that stays out of your way and doesn't require memorizing hidden conventions
• Work on small-to-medium projects — you want structure and best practices without the overhead of enterprise-grade frameworks
• Want full control — you believe that understanding your tools is more important than having hundreds of features out of the box

If you're looking for a batteries-included framework with built-in ORM, pre-configured queue workers, and ready-made broadcast drivers — Rudra is not for you.
If you want a lightweight, transparent foundation with simple primitives that you can extend exactly as needed — you're in the right place.

🔑 Secret Keys

Secret keys are automatically generated during Composer installation for all environments (local, ddev, production). If you need to regenerate them (e.g., after cloning the repository), simply run:

php rudra secret

⚙️ Configuration

Rudra uses environment-specific configuration files. The framework automatically loads the appropriate file based on your environment:

Environment	Config File
DDEV	config/setting.ddev.yml
Local development	config/setting.local.yml
Production	config/setting.production.yml

These files contain database credentials, container paths, debug settings, and other environment-specific values.

🗄️ Database Configuration

Rudra uses a simple, explicit YAML configuration for database connections. There is no hidden magic or auto-guessing: you define exactly which driver and credentials to use for each environment.

Local Development (config/setting.local.yml):

database:
    dsn: mysql:dbname=db;host=127.0.0.1
    # dsn: pgsql:host=127.0.0.1;port=5432;dbname=db;
    # dsn: sqlite:/path-to/app/Ship/Data/rudra.sqlite
    username: jagepard
    password: password

DDEV Environment (config/setting.ddev.yml):

database:
    dsn: mysql:dbname=db;host=db;port=3306
    # dsn: pgsql:host=db;port=5432;dbname=db;
    # dsn: sqlite:/path-to/app/Ship/Data/rudra.sqlite
    username: root
    password: root
    # For pgsql in DDEV:
    # username: db
    # password: db

Production (config/setting.production.yml):

database:
    dsn: mysql:dbname=db;host=127.0.0.1 # Replace with your production host
    username: your_prod_user
    password: your_prod_password

💡 Tip: The framework's Query Builder (Rudra-Model) automatically reads these settings based on the active environment. Simply uncomment the dsn line for your preferred database engine (MySQL, PostgreSQL, or SQLite).

🌐 Web Environment (auto-detected)

For web requests, Rudra automatically detects the environment in index.php:

$env = match (true) {
    getenv('IS_DDEV_PROJECT') === 'true' => 'ddev',
    php_sapi_name() === 'cli-server' => 'local',
    default  => 'production',
};

🖥️ Console Environment

For CLI commands (like php rudra migrate), the framework cannot auto-detect the environment as it does in index.php. Instead, it relies on the app_env.php file to determine which configuration file to load (e.g., 'local' → config/setting.local.yml).

🚀 Quick Setup (Recommended)

Use the built-in interactive command to set or change your environment. It will automatically create or update the app_env.php file for you, preserving all comments and structure:

php rudra env

Follow the interactive prompt to select 1 (local), 2 (ddev), or 3 (production).

⚙️ Manual Setup

If you prefer, you can manually create or edit the app_env.php file in your project root:

<?php
// Do NOT commit this file to Git (.gitignore)
return 'local'; // ← Set to: 'local', 'ddev', or 'production'

ℹ️ Note: If app_env.php is missing (e.g., if you cloned the repository directly instead of using composer create-project), the framework defaults to 'local' for CLI commands. This is safe for local development but should not be relied upon in production — always create the file manually or set the APP_ENV server variable explicitly.

💡 Tip: When adding new containers or settings during development, update config/setting.local.yml. For production deployment, copy the relevant sections to config/setting.production.yml.

Run the development server

php rudra serve

🚀 Creating Your First Page

Let's create a simple /hello/:name page that greets the user. This example shows the full flow: container → controller → route → browser.

1. Create a container

php rudra make:container

Enter container name: web

This creates the App\Containers\Web\ namespace and registers it in config/setting.local.yml.

💡 Don't forget to also register it in config/setting.ddev.yml and config/setting.production.yml if needed.

2. Create a controller

php rudra make:controller

Enter controller name: hello
Enter container: web

This generates App/Containers/Web/Controller/HelloController.php.

3. Define the route and action

Open the controller and add a method with the #[Routing] attribute:

<?php

namespace App\Containers\Web\Controller;

use App\Containers\Web\WebController;
use Rudra\Router\Attribute\Routing;
use Rudra\Container\Facades\Request;

class HelloController extends WebController
{
    #[Routing(url: 'hello/:name', method: 'GET')]
    public function greet(string $name): void
    {
        echo "<h1>Hello, {$name}!</h1>";
        echo "<p>Your lucky number is: " . random_int(1, 100) . "</p>";
    }
}

That's it. The route is registered automatically via the attribute — no separate routes.php needed.

4. Open in browser

http://127.0.0.1:8000/hello/world

You should see: Hello, world! Your lucky number is: 42

---

Alternative: routes.php

If you prefer to keep routes separate from controllers, create (or edit) App/Containers/Web/routes.php:

<?php

use Rudra\Router\RouterFacade as Router;
use App\Containers\Web\Controller\HelloController;

Router::get('hello/:name', [HelloController::class, 'greet']);

⚠️ When using routes.php for manual routing, make sure the file returns an empty array to disable automatic attribute-based route registration:

return [];

Alternative: closure route

For quick prototyping, you can even skip the controller entirely:

Router::get('hello/:name', function (string $name) {
    echo "Hello, {$name}!";
});

Then open http://127.0.0.1:8000 in your browser.

🔑 Key Features in Action

🔐 Authentication & RBAC

use Rudra\Auth\AuthFacade as Auth;

// Registration
$user = [
    "email"    => "user@email.com",
    "password" => Auth::bcrypt("password")
];

// Authentication (plain password vs hash from DB)
Auth::authentication($user, "password", ["admin/dashboard", "login"]);

// Authorization check (redirects to 'login' if not authenticated)
if (!Auth::authorization(null, "login")) {
    exit;
}

// Role-Based Access Control
if (!Auth::roleBasedAccess($currentRole, "editor", "error/403")) {
    exit;
}

🎧 Event Dispatcher (Listeners + Observers)

use Rudra\EventDispatcher\EventDispatcherFacade as Dispatcher;

// Listeners — pub/sub with payload
Dispatcher::addListener('user.registered', [UserListener::class, 'onRegister']);
Dispatcher::dispatch('user.registered', ['id' => 1, 'email' => '...']);

// Observers — stateless notifications (no payload)
Dispatcher::attachObserver('before', [AuditObserver::class, 'onEvent']);
Dispatcher::notify('before');

✅ Fluent Validation

use Rudra\Container\Facades\Request;
use Rudra\Container\Facades\Session;
use Rudra\Validation\ValidationFacade as V;

$fields    = Request::post()->all();
$processed = [
    'name'        => V::sanitize($fields['name'])->required()->min(3)->max(50)->run(),
    'email'       => V::email($fields['email'])->run(),
    'age'         => V::sanitize($fields['age'])->integer()->between(18, 100)->run(),
    'description' => V::set($fields['description'])->run(), // without validation
    'csrf'        => V::sanitize($fields['csrf'])->csrf(Session::get('csrf_token'))->run(),
];

if (V::approve($processed)) {
    $data = V::getValidated($processed, ["csrf", "_method"]);
} else {
    $errors = V::getErrors($processed);
}

🧭 RESTful Resources

Registers standard CRUD routes with explicit plural and singular URL patterns. No magic pluralization — you define exactly what the URLs look like.

$router->resource('api/users', 'api/user', UserController::class);

This creates the following routes:

Method	URL	Controller Method	Description
GET	api/users	index	List all users
GET	api/user/:id	read	Get single user
POST	api/users	create	Create new user
PUT	api/user/:id	update	Full update of user
PATCH	api/user/:id	update	Partial update of user
DELETE	api/user/:id	delete	Delete user

The default action names are ['index', 'read', 'create', 'update', 'delete'].

Custom Method Names

You can override the default action names by passing a custom array of 5 methods:

$router->resource('api/posts', 'api/post', PostController::class, [
    'actionIndex',   // GET    api/posts       — list all posts
    'actionView',    // GET    api/post/:id    — get single post
    'actionAdd',     // POST   api/posts       — create new post
    'actionUpdate',  // PUT/PATCH api/post/:id — update post
    'actionDrop'     // DELETE api/post/:id    — delete post
]);

The array order is fixed: [index, read, create, update, delete].

🖼️ View with Caching

use Rudra\View\ViewFacade as View;

// Cache-first strategy with fallback
echo View::cache(['mainpage', "+1 day"]) ?? View::render(["layout", "mainpage"], [
    'content' => View::cache(["page_{$slug}", "+1 day"]) 
        ?? View::view(["page", "page_{$slug}"], ['foo' => 'bar']),
]);

// Or with helpers
data(['content' => cache(['mainpage']) ?? view(['index', 'mainpage'])]);
render('layout', data());

💾 Data Access Layer (Rudra-Model)

Rudra includes a lightweight, transparent data access layer — not a heavy ORM, but a simple Query Builder with Repository pattern.

Architecture: Entity → Model → Repository

A predictable delegation chain with automatic fallback:

• Entity — entry point, defines the table name
• Model — business logic layer (optional)
• Repository — data access layer (optional, falls back to base CRUD)

If you don't create a Model or Repository, the base Repository handles standard CRUD automatically.

Zero Boilerplate

namespace App\Containers\User\Entity;

use Rudra\Model\Entity;

class User extends Entity
{
    public static ?string $table = 'users';
}

// Usage — no Model or Repository needed:
// These methods are provided by the base Repository automatically
$users = User::getAll();
$user  = User::find(1);
User::create(['name' => 'John', 'email' => 'john@example.com']);

Custom Repository Logic

namespace App\Containers\User\Repository;

use Rudra\Model\Repository;

class UserRepository extends Repository
{
    public function findActiveUsers(): array
    {
        return $this->qBuilder("SELECT * FROM {$this->table} WHERE active = 1");
    }
}

// Automatically routed:
$activeUsers = User::findActiveUsers();

Fluent Query Builder

use Rudra\Model\QBFacade as QB;

$query = QB::select('id, name, email')
    ->from('users')
    ->where('status = :status')
    ->and('role = :role')
    ->orderBy('created_at DESC')
    ->limit(10)
    ->get(); // Returns SQL query string

// Execute via Repository:
$results = User::qBuilder($query, ['status' => 'active', 'role' => 'admin']);

Schema Builder

use Rudra\Model\Schema;

Schema::create('users', function ($table) {
    $table->integer('id', autoincrement: true)
          ->string('name')
          ->string('email')
          ->text('bio', 'NULL')
          ->createdAt()
          ->updatedAt()
          ->primaryKey('id'); // Explicitly declare primary key
})->execute();

File-Based Caching

Simple, reliable JSON file caching — no Redis/Memcached required:

// Cache the result of User::getAll() method
$users = User::cache(['getAll']);

// Cache Post::findBy('category', 'news') with 1 hour TTL
$posts = Post::cache(['findBy', ['category', 'news']], '+1 hour');

// Auto-clears on create/update/delete

Why Not a Heavy ORM?

• No magic — no hidden queries, no lazy loading surprises
• No hidden dependencies — direct PDO access when needed
• Predictable — you see exactly what SQL is executed
• Fast — no reflection overhead, no entity hydration complexity
• Simple — if you know SQL, you know Rudra-Model
