Laravel Latte

Add support for the Latte templating engine in Laravel views.

Features

Render .latte views
Latte engine configurable via facade
Translation provider to access localized messages
Laravel-style path resolution when including partials
Extensive test coverage

Installation

composer require daun/laravel-latte

Requirements

PHP 8.1+
Laravel 9/10/11

Usage

Installing the composer package will automatically register a Service Provider with your Laravel app. You can now render Latte files like you would any other view. The example below will render the view at resources/views/home.latte using Latte.

Route::get('/', function() {
    return view('home');
});

Configuration

The package will read its configuration from config/latte.php. Use Artisan to publish and customize the default config file:

php artisan vendor:publish --provider="Daun\LaravelLatte\ServiceProvider"

Localization

The package includes a custom translator extension that acts as a bridge to Laravel's translation service. It allows using any translations registered in your app to be used in Latte views, using either the _ tag or the translate filter:

{_'messages.welcome'}
{('messages.welcome'|translate)}

You can pass in parameters as usual:

{_'messages.welcome', [name: 'Adam']}
{('messages.welcome'|translate:[name: 'Adam'])}

Translate using a custom locale by passing it after or in place of the params:

{_'messages.welcome', [name: 'Mary'], 'fr'}
{_'messages.welcome', 'fr'}

Pluralization works using the transChoice filter.

{('messages.apples'|transChoice:5)}

Path resolution

The package includes a custom loader that allows including partials from subdirectories using Laravel's dot notation to specify folders.

{* resolves to /resources/views/partials/slideshow/image.latte *}

{include 'partials.slideshow.image'}

To specifically include files relative to the current file, prefix the path with ./ or ../:

{include './image.latte'}

Default layout

If you require a common layout file for all views, you can define a default layout in config/latte.php. Any views without a specifically set layout will now be merged into that layout.

[
    // /resources/views/layouts/default.latte
    'default_layout' => 'layouts.default'
]

Configuring Latte

Extensions

To extend Latte and add your own tags, filters and functions, you can use the extensions array in config/latte.php to supply a list of Latte extensions to register automatically.

[
    'extensions' => [
        \App\View\Latte\MyExtension::class
    ]
]

Facade

You can also directly access and configure the Latte engine instance from the Latte facade. Modify its config, add custom filters, etc.

use Daun\LaravelLatte\Facades\Latte;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        Latte::addFilter('plural', fn($str) => Str::plural($str));
    }
}

Events

If you need to be notified when the Latte engine is created, listen for the LatteEngineCreated event to receive and customize the returned engine instance.

use Daun\LaravelLatte\Events\LatteEngineCreated;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function register()
    {
        Event::listen(function (LatteEngineCreated $event) {
            $event->engine->setAutoRefresh(true);
        });
    }
}
