Transitive\Web

HTTP front controller and HTML-oriented view layer for Transitive.

This package builds on transitive/core and transitive/routing to provide browser-facing rendering, content negotiation, default HTML layout handling, and helpers for scripts, styles, and metadata.

Installation

composer require transitive/web

PHP 8.1+ is required.

What is included

• Transitive\Web\Front: an HTTP front controller with Accept header negotiation and response header management.
• Transitive\Web\View: a richer (than Transitive\Simple) view implementation with title, meta tag, stylesheet, and script helpers.

Basic Usage

<?php

use Transitive\Web;
use Transitive\Routing;

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

$front = new Web\WebFront();

$front->addRouter(new Routing\PathRouter(dirname(dirname(__FILE__)).'/presenters', dirname(dirname(__FILE__)).'/views'));

$front->execute(@$_GET['request'] ?? 'index');

echo $front;

Response formats

Transitive\Web\Front can emit different representations depending on the resolved content type, including:

• HTML and XHTML
• JSON
• XML
• YAML
• raw stylesheet content
• raw script content
• serialised document/head/content payloads

By default it inspects $_SERVER['HTTP_ACCEPT'] and chooses the best supported MIME type.

View helpers

Transitive\Web\View extends the simple core view with helpers such as:

• addMetaTag() / addRawMetaTag()
• addStyle() / linkStyleSheet() / importStyleSheet()
• addScript() / linkScript() / importScript()
• getHead(), getMetas(), getStyles(), and getScripts()

Example:

<?php

use Transitive\Web\View;

$view = new View();
$view->setTitle('Home');
$view->addMetaTag('description', 'Example page');
$view->linkStyleSheet('/assets/site.css');
$view->linkScript('/assets/site.js', defer: true);
$view->addContent(function($data) {
	echo '<h1>Hello '.$data['name'].'</h1>';
}, 'text/html');
