SymPress Assets

Asset management for SymPress WordPress packages, plugins, and themes.

The package registers classic scripts, script modules, and styles through a Composer library. It can run standalone in WordPress or through the optional Symfony kernel integration.

Installation

composer require sympress/assets

Features

• Scripts, script modules, and styles with one shared asset API
• Webpack manifest, Encore, array, and PHP file loaders
• Automatic versions from file paths or dependency extraction files
• Native script loading strategies: defer, async, blocking
• Style preload for non-critical CSS
• Resource hints for preload, preconnect, and dns-prefetch
• Protection from cache, minify, combine, defer, and delay optimizations
• Optional Symfony kernel integration with asset providers

Example

<?php

use SymPress\Assets\AssetManager;
use SymPress\Assets\Script;
use SymPress\Assets\Style;

add_action(
    AssetManager::ACTION_SETUP,
    static function (AssetManager $assets): void {
        $assets->register(
            new Script('site', plugin_dir_url(__FILE__) . 'assets/site.js'),
            new Style('site', plugin_dir_url(__FILE__) . 'assets/site.css'),
        );
    }
);

Classic scripts use WordPress' native defer strategy by default. Styles remain blocking unless Style::preload() is enabled for non-critical CSS.

Standalone WordPress

When the Symfony kernel is not used, load inc/bootstrap.php once after the Composer autoloader.
