Installtion

Optional use LightHttp package for custom responses

composer require nabeelalihashmi/lighthttp

Basic Usage

Create a new file .htaccess in your project root directory.

Options -Indexes
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . public/index.php [L]

Here is sample code for index.php

<?php
function getRoutes()
{
    return [
        ['GET', '/', [HomeController::class, 'index'], []],
        ['POST', '/', [HomeController::class, 'posts'], [LoginCheck::class]],
        ['GET', '/user/someuser/icon', [HomeController::class, 'index'], [LoginCheck::class]],
        ['GET', '/user/.+', [HomeController::class, 'user'], [LoginCheck::class]]
    ];
}


$router = new Router;
$router->setRoutes(getRoutes());
$router->setNotFound(function() {
    header('HTTP/1.1 404 Not Found');
    echo '404 Not Found';
});

$router->run();

Here is demo Controller

<?php

namespace App\Controllers;

class HomeController
{
    public function index()
    {
        echo 'Hi';
    }

    public function posts() {
        echo 'My posts';
    }

    public function user($id) {
        echo 'Here';
        var_dump($id);
    }
}

Here is demo Middleware

<?php

namespace App\Middlewares;

use IconicCodes\LightRouter\IMiddleware;

class LoginCheck implements IMiddleware{
    public function handle() {
        return true;
    }
}

Routing

Execution

Request -> Before Middlewares -> Callback -> After Middlwares

You can add routes by following methods

1. setRoutes
2. addRoute

But first you need to know about a route structure. In LightRouter, a route structure is an array with this pattern

[
    'METHOD | String',
    'URI | String',
    'CALLBACK | Array or Callback',
    'BEFORE_MIDDLEWARES | Array'
    'After_MIDDLEWARES | Array'
]

you can either set routes one by one like:

$router->addRoute('GET', '/', [HomeController::class, 'index'], [MyMiddleware::class]);

or You can set all routes at once using setRoutes method like this

$router->setRoutes([
    ['GET', '/', [HomeController::class, 'index'], [MyMiddleware::class]],
    ['POST', '/', [HomeController::class, 'posts'], [MyMiddleware::class]],
    ['GET', '/user/someuser/icon', [HomeController::class, 'index'], [MyMiddleware::class]],
    ['GET', '/user/.+', [HomeController::class, 'user'], [MyMiddleware::class]]
]);

Dynamic Routes

LightRouter supports dynamic routes. You can use .+ in your URI, and in callback function, you can use variables according to position.

$router->addRoute('GET', '/user/{arg1}/{arg2}', [HomeController::class, 'user'], [MyMiddleware::class]);

class HomeController {
    public function user($id, $name) {
        var_dump($id);
        var_dump($name);
    }
}

Responses

NOTE: Reponses are removed from LightRouter packages and they are part of LightHttp

To make it modular and independant, you can plug LightHttp IResponse or use own.

$router->response_type_interface_name = gettype('IconicCodes\LightHttp\Responses\IResponse);

You can make your own reponse handler too. It must have 'handle' method.

Controllers/callbacks can return a Response implementing `IResponse` interface having `handle` method. By default LightRouter has these Responses

• LResponse
• LJSONResponse
• LRedirectResponse

Methods

LightRouter has only these methods:

setRoutes(array $routes)

$router->setRoutes([...]);

addRoute($array route)

$router->addRoute('GET', '/', [HomeController::class, 'index'], [MyMiddleware::class]);

run()

$router->run();

setNotFound(callback $callback)

$router->setNotFound(function() {
    header('HTTP/1.1 404 Not Found');
    echo '404 Not Found';
});
