README

This package integrates the Jaxon library into the Slim framework.

Installation

The version 4 of the package requires Slim version 4.

Install the package with Composer.

composer require jaxon-php/jaxon-slim ^4.0

Or

{
    "require": {
        "jaxon-php/jaxon-slim": "^4.0",
    }
}

And run composer install.

Routing and middlewares

This package uses two Jaxon PSR middlewares, one to load the Jaxon config, and the other to process Jaxon requests. The Jaxon config middleware must be attached to all the routes where the Jaxon features are enabled, while the later must be attached to the route that processes Jaxon requests.

<?php

use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Server\RequestHandlerInterface as RequestHandler;
use Slim\Factory\AppFactory;
use Slim\Psr7\Response;
use function Jaxon\jaxon;

require __DIR__ . '/../vendor/autoload.php';

$app = AppFactory::create();

// Jaxon middleware to load config
// Set a container if you need to use its services in Jaxon classes.
// Set a logger if you need to send messages to your logs in Jaxon classes.
$jaxonConfigMiddleware = function(Request $request, RequestHandler $handler) {
    return jaxon()->psr()
        // Uncomment the following line to set a container
        // ->container($container)
        // Uncomment the following line to set a logger
        // ->logger($logger)
        ->config(__DIR__ . '/../config/jaxon.php')->process($request, $handler);
};

// Process Jaxon ajax requests
$app->group('/', function() use($app) {
    // Jaxon middleware to process ajax requests
    $jaxonAjaxMiddleware = function(Request $request, RequestHandler $handler) {
        return jaxon()->psr()->ajax()->process($request, $handler);
    };

    $app->post('/jaxon', function($request, $response) {
        // Todo: return an error. Jaxon could not find a plugin to process the request.
    })->add($jaxonAjaxMiddleware);

    // Insert Jaxon codes in a page
    $app->get('/', function($request, $response) {
        // Display a page with Jaxon js and css codes.
        $jaxon = jaxon()−>app();
        $css = $jaxon->css();
        $js = $jaxon->js();
        $script = $jaxon->script();
        // Display the page
        ...
    });
})->add($jaxonConfigMiddleware);

Setting the view renderer

The Slim framework provides two components for view rendering, and both can be used with the Jaxon view renderer.

The Twig-View component displays Twig views.

// Add Twig-View Middleware
$twig = Twig::create(__DIR__ . '/../templates', ['cache' => false]);
$app->add(TwigMiddleware::create($app, $twig));

$jaxonConfigMiddleware = function(Request $request, RequestHandler $handler) {
    return jaxon()->psr()
        ->view('slim', '.html.twig', function() use($request) {
            $view = Twig::fromRequest($request);
            return new \Jaxon\Slim\View($view);
        })
        ->config(__DIR__ . '/../jaxon/config.php')->process($request, $handler);
};

The PHP-View component displays PHP views.

$jaxonConfigMiddleware = function(Request $request, RequestHandler $handler) {
    return jaxon()->psr()
        ->view('slim', '.php', function() use($request) {
            $view = new PhpRenderer(__DIR__ . '/../templates');
            return new \Jaxon\Slim\View($view);
        })
        ->config(__DIR__ . '/../jaxon/config.php')->process($request, $handler);
};

Usage

The settings in the config/jaxon.php config file are separated into two sections. The options in the lib section are those of the Jaxon core library, while the options in the app sections are those of the Slim application.

The following options can be defined in the app section of the config file.

Name	Description
directories	An array of directory containing Jaxon application classes
views	An array of directory containing Jaxon application views

By default, the views array is empty. Views are rendered from the framework default location. There's a single entry in the directories array with the following values.

Name	Default value	Description
directory	ROOT . '/jaxon/ajax'	The directory of the Jaxon classes
namespace	\Jaxon\Ajax	The namespace of the Jaxon classes
separator	.	The separator in Jaxon class names
protected	empty array	Prevent Jaxon from exporting some methods

Usage

The Jaxon classes

The Jaxon classes can inherit from \Jaxon\App\CallableClass. By default, they are located in the jaxon/ajax dir of the Slim application, and the associated namespace is \Jaxon\Ajax.

This is an example of a Jaxon class, defined in the ROOT/jaxon/Ajax/HelloWorld.php file.

namespace Jaxon\Ajax;

class HelloWorld extends \Jaxon\App\CallableClass
{
    public function sayHello()
    {
        $this->response->assign('div2', 'innerHTML', 'Hello World!');
        return $this->response;
    }
}
