Litero

Extra light router and dispatcher for small web applications. Small footprint and no overhead.

Router class in this package maps HTTP-requests by URL pattern to callbacks.

Note: It's component not support PSR-7 HTTP Message Interface out of the box.

Installing

Create project based on Litero in current directory:

composer create-project bit55/litero .

And add your application code to autoloading section in composer.json.

Or include Litero in your existing project:

composer require bit55/litero

Or download this repository and include file Router.php in your project.

Your webserver must point to the index.php file for any URI entered. See .htaccess for Apache and example.nginx.conf for Nginx configuration example.

Usage

Create Instance of Router class.

$router = Bit55\Litero\Router::fromGlobals();

Add routing rules. Routes may contents exact or wildcard rules.

Wildcards example:

• /page/:seg - any characters in one segment like /page/qwerty or /page/123;
• /page/:num - digits only like /page/123;
• /page/:any - any characters like /page/qwerty or /page/qwerty/123;

Route handler may be any callable (function name, closure) or string with controller class name and action method. Router instantiate controller and execute action method automatically.

Wildcard parameters will be passed as function params in handler.

Note if you using Composer, add your controller classes to autoloading.

Add single rule with Closure handler:

$router->add('/', function () {
    echo 'Hello from Litero!';
});

Or add array of routes.

$router->add([
    '/first'       => 'Bit55\Litero\ExampleController@firstAction',
    '/second/:any'  => 'Bit55\Litero\ExampleController@secondAction',
]);

Start route processing.

if ($router->isFound()) {
    $router->executeHandler(
        $router->getRequestHandler(),
        $router->getParams()
    );
} 
else {
    // Simple "Not found" handler
    $router->executeHandler(function () {
        http_response_code(404);
        echo '404 Not found';
    });
}

Usage example code see in index.php file.
