README

Routelite is a lightweight PHP routing library for building flexible and maintainable web applications.
It supports route parameters, middlewares, route groups, prefixes, and multi-language URLs.

Features

• Supports GET and POST routes.
• Route-specific, group, and global Middleware support.
• Route parameters with Regex validation.
• Prefix support for route groups or individual routes.
• Multi-language URL support.
• Custom 404 Not Found handling.
• Singleton pattern to ensure only one instance.
• Ability to remove unwanted text from URLs before processing.

Installation

You can install Routelite manually or via Composer:

composer require 91ahmed/routelite

Use it in your project:

use Router\Routelite;

$route = Routelite::collect();

Basic Usage

1. Defining a simple route

$route->get('/', 'Controller\HomeController@index')->add();
$route->post('/submit', 'Controller\FormController@submit')->add();

2. Route parameters with regex validation

$route->get('/user/profile', 'Controller\UserController@profile')
      ->params(['id', 'username'])
      ->where('id', '/^[0-9]+$/')
      ->where('username', '/^[a-zA-Z0-9]+$/')
      ->add();

3. Using Middleware

• Route-specific middleware:

$route->get('/dashboard', 'Controller\Dashboard@index')
      ->middleware(['auth', 'log'])
      ->add();

• Group middleware:

$route->middlewareGroup(['auth'], function ($route) {
    $route->get('/users/all', 'Controller\UserController@index')->add();
});

• Global middleware for all routes:

$route->middlewareGlobal(['session']);

4. Route Groups and Prefixes

$route->prefixGroup('dashboard', function ($route) {
    $route->middlewareGroup(['auth'], function ($route) {
        $route->get('/users/all', 'Controller\UserController@index')->add();
        $route->get('/home', 'Controller\HomeController@home')->add();
    });
});

• All routes inside the dashboard prefix group will start with /dashboard/....
• Middleware auth is applied to all routes inside the middleware group.

5. Multi-language support

$route->setLanguage(['ar', 'en']);

• The first segment of the URL will be treated as the language:

  • /ar/dashboard → Arabic
  • /en/dashboard → English

6. Removing unwanted text from URLs

$route->remove('Unwanted Word');

• The remove() method allows you to filter out specific parts of the URL before route processing.
  This is especially useful in development environments, like when working on localhost, where your project might be inside a subfolder.

7. Handling 404 Not Found

$route->notFound(function () {
    exit('404 Not Found Page');
});

• Executes the callback if no matching route is found or there is a parameter error.

8. Listing all routes

$allRoutes = $route->getRoutes();
print_r($allRoutes);

9. Rendering Routes

After defining all your routes, you must call the render() method to process the current request and execute the matching route:

$route->render();

• render() will match the current URL against all defined routes.
• It executes the associated controller action if a match is found.
• If no match is found, you can handle it using notFound():

$route->notFound(function () {
    exit('404 Not Found Page');
});

Important: Always call render() after all route definitions. Without it, no routes will be processed.

Full Example

use Router\Routelite;

$route = Routelite::collect();

$route->middlewareGlobal(['session']);

$route->setLanguage(['ar', 'en']);

$route->prefixGroup('dashboard', function ($route) {
    $route->middlewareGroup(['auth'], function ($route) {
        $route->get('/users/all/', 'Controller\HomeController@index')
              ->params(['id', 'username'])
              ->where('id', '/^[0-9]+$/')
              ->where('username', '/^[a-zA-Z0-9]+$/')
              ->add();

        $route->get('/home/', 'Controller\HomeController@home')->add();
    });
});

$route->get('/', 'Controller\HomeController@index')->params(['lang'])->middleware(['auth'])->add();
$route->get('/admin', 'Controller\HomeController@admin')->params(['id'])->add();
$route->post('/users', 'Controller\HomeController@admin')->add();

$route->render();

$route->notFound(function () {
    exit('404 Not Found Page');
});

Important Notes

• Middleware names must contain only letters, numbers, underscores, or valid namespaces.
• All middleware classes must implement a handle() method.
• Magic methods in controllers (e.g., __construct, __call) are not allowed.
• Middleware execution order: Global → Group → Route.
• Always use Routelite::collect() to get the same instance. Do not create a new instance manually.
• setLanguage([...]) should be called before defining routes that depend on language.
• When using params([...]), the order of parameter names must match their order in the URL.
• The handle() method in middleware must return true to continue or false to stop execution.
• After defining all routes, you must call render() to execute the matching route. Without render(), no routes will be processed.
