🚀 Instalação

Via Composer

composer require devpontes/view

Ou adicione manualmente ao seu composer.json:

{
  "require": {
    "devpontes/view": "4.0.*"
  }
}

Depois execute:

composer install

⚡ Uso Rápido

1. Defina o caminho das views

$viewPath = 'views';

2. Inicialize o View

$v = new \DevPontes\View\View($viewPath, 'php');

3. Defina os componentes do layout

$v->setHead('includes.head');
$v->setHeader('includes.header');
$v->setAside('includes.aside');
$v->setFooter('includes.footer');

4. Prepare seus dados e renderize

$data = ['user' => $user, 'posts' => $posts];
$v->render('home', $data);

📚 Documentação Completa

Classe View

A classe View é responsável por renderizar os templates e gerenciar o layout da aplicação.

Construtor

$v = new \DevPontes\View\View(string $viewPath, string $extension)

Parâmetro	Tipo	Descrição
`$viewPath`	string	Caminho para a pasta contendo os arquivos de view
`$extension`	string	Extensão dos arquivos de template (padrão: `php`)

Exemplo:

$v = new \DevPontes\View\View('src/views', 'php');

Métodos de Configuração do Layout

`setHead(string $head): View`

Define o arquivo a ser incluído no início do template (dentro da tag <head>).

$v->setHead('includes.head');
// Carregará: views/includes/head.php

`setHeader(string $header): View`

Define o arquivo de cabeçalho da página.

$v->setHeader('includes.header');
// Carregará: views/includes/header.php

`setAside(string $aside): View`

Define o arquivo da barra lateral/menu.

$v->setAside('includes.aside');
// Carregará: views/includes/aside.php

`setFooter(string $footer): View`

Define o arquivo de rodapé da página.

$v->setFooter('includes.footer');
// Carregará: views/includes/footer.php

Todos os métodos retornam View, permitindo encadeamento:

$v->setHead('includes.head')
  ->setHeader('includes.header')
  ->setAside('includes.aside')
  ->setFooter('includes.footer');

Método de Renderização

`render(string $view, array $data = []): void`

Renderiza um template com os dados fornecidos. O layout é aplicado conforme definido nos métodos anteriores.

$v->render('home', [
    'user' => $user,
    'posts' => $posts,
    'settings' => $config
]);

Ordem de renderização:

Head
Header
Aside
View principal
Footer

Métodos Utilitários

`insert(string $view): void`

Insere um componente diretamente dentro de uma view. Útil para componentes reutilizáveis.

<?php $this->insert('components.article') ?>

Esta linha carregará o arquivo views/components/article.php.

`data(): object`

Retorna os dados passados para o template convertidos para stdClass.

$data = $this->data();
echo $data->user->name;

`get($name)` e `isset($name)`

Permite acessar dados como propriedades da view.

// Em vez de fazer isso:
$this->data()['user']

// Você pode fazer isto:
$this->user

Classe Assets

A classe Assets gerencia o carregamento dinâmico de arquivos CSS e JavaScript com suporte a versionamento automático para controle de cache.

Construtor

$a = new \DevPontes\View\Assets(string $src, bool $cache = true)

Parâmetro	Tipo	Padrão	Descrição
`$src`	string	—	Caminho raiz para a pasta de assets
`$cache`	bool	`true`	Ativar caching (true) ou versionamento (false)

Exemplos:

// COM caching (produção)
$a = new \DevPontes\View\Assets('assets', true);
// Gera: <link rel="stylesheet" href="assets/css/style.css">

// SEM caching (desenvolvimento)
$a = new \DevPontes\View\Assets('assets', false);
// Gera: <link rel="stylesheet" href="assets/css/style.css?v=1709632527">

Métodos de CSS

`makeStyle(array $css): Assets`

Define quais arquivos CSS devem ser carregados.

$css = ['bootstrap', 'style', 'responsive'];
$a->makeStyle($css);

Estrutura esperada:

assets/
├── css/
│   ├── bootstrap.css
│   ├── style.css
│   └── responsive.css

HTML gerado:

<link rel="stylesheet" href="assets/css/bootstrap.css" />
<link rel="stylesheet" href="assets/css/style.css" />
<link rel="stylesheet" href="assets/css/responsive.css" />

`getStyles(): string`

Retorna o HTML com as tags <link> de CSS.

<head>
  <title>Meu Site</title>
  <?= $this->assets->getStyles() ?>
</head>

`setStylePath(string $stylePath): Assets`

Customiza o caminho padrão para arquivos CSS (padrão: assets/css).

$a->setStylePath('vendor/styles');
// Muda para: assets/vendor/styles/

Métodos de JavaScript

`makeScript(array $js): Assets`

Define quais arquivos JavaScript devem ser carregados.

$js = ['jquery', 'popper', 'bootstrap', 'app'];
$a->makeScript($js);

Estrutura esperada:

assets/
├── js/
│   ├── jquery.js
│   ├── popper.js
│   ├── bootstrap.js
│   └── app.js

HTML gerado:

<script src="assets/js/jquery.js"></script>
<script src="assets/js/popper.js"></script>
<script src="assets/js/bootstrap.js"></script>
<script src="assets/js/app.js"></script>

`getScripts(): string`

Retorna o HTML com as tags <script>.

<body>
  <!-- conteúdo -->
  <?= $this->assets->getScripts() ?>
</body>

`setScriptPath(string $scriptPath): Assets`

Customiza o caminho padrão para arquivos JavaScript (padrão: assets/js).

$a->setScriptPath('vendor/scripts');
// Muda para: assets/vendor/scripts/

Integração com View

$a = new \DevPontes\View\Assets('assets', false);
$v = new \DevPontes\View\View('views', 'php');

// Adicionar assets ao view
$v->addAssets($a);

// Configurar assets
$v->assets->makeStyle(['bootstrap', 'style']);
$v->assets->makeScript(['jquery', 'app']);

// Agora você pode usar $this->assets nos templates

💡 Exemplos Práticos

Exemplo 1: Setup Básico Completo

<?php
require "vendor/autoload.php";

// Dados da aplicação
$user = new \stdClass();
$user->name = "John Doe";
$user->email = "john@example.com";

$data = [
    'user' => $user,
    'title' => 'Welcome to My Site'
];

// Inicializar View
$v = new \DevPontes\View\View('views', 'php');

// Configurar layout
$v->setHead('includes.head')
  ->setHeader('includes.header')
  ->setAside('includes.aside')
  ->setFooter('includes.footer');

// Renderizar
$v->render('home', $data);
?>

Exemplo 2: Com Controle de Assets

<?php
require "vendor/autoload.php";

// Dados
$data = ['products' => $products];

// Assets
$a = new \DevPontes\View\Assets('assets', false); // false = versionamento para dev
$a->makeStyle(['bootstrap', 'style', 'theme']);
$a->makeScript(['jquery', 'bootstrap', 'app']);

// View
$v = new \DevPontes\View\View('views', 'php');
$v->addAssets($a);
$v->setHead('includes.head')
  ->setHeader('includes.header')
  ->setFooter('includes.footer');

// Renderizar
$v->render('products.list', $data);
?>

Exemplo 3: Layout sem alguns componentes

<?php
$v = new \DevPontes\View\View('views', 'php');

// Renderizar apenas com header e footer
$v->setHeader('includes.header')
  ->setFooter('includes.footer');

// Aside não é definido, então não aparecerá
$v->render('page.login', $data);
?>

Exemplo 4: Templates com Componentes

views/products.php:

<main class="products">
    <h1><?= $title ?></h1>

    <div class="products-grid">
        <?php foreach ($products as $product): ?>
            <?php $this->insert('components.product-card'); ?>
        <?php endforeach; ?>
    </div>
</main>

views/components/product-card.php:

<div class="card">
    <img src="<?= $product->image ?>" alt="<?= $product->name ?>">
    <h3><?= $product->name ?></h3>
    <p>R$ <?= number_format($product->price, 2, ',', '.') ?></p>
    <a href="/product/<?= $product->id ?>">View Details</a>
</div>
