Performance & Footprint

This plugin is built with a "Performance First" philosophy. Unlike many all-in-one plugins that slow down your site, Functionalities is designed to be as lightweight as possible:

  • Modular Initialization: Each module checks its enabled state before registering its feature hooks. Disabled modules add no frontend assets or feature behavior.
  • Minimized Database Load: All module settings are cached in static properties. This ensures that get_option() is called at most once per module per request, regardless of how many times a feature is accessed.
  • Zero Frontend Bloat: Most modules are "Zero Footprint" on the frontend, meaning they load no CSS or JS unless explicitly required (like the Components or Fonts modules).
  • Intelligent Filtering: Content filters (the_content, etc.) use strpos() fast-exit checks. If the specific markers or tags for a feature aren't present in your content, the plugin exits immediately without running expensive regular expressions or DOM parsing.
  • Efficient HTML Processing: We use targeted regex for lightweight tasks (like Schema injection) and only resort to DOMDocument when structural manipulation is strictly necessary, ensuring maximum speed.
  • Aggressive Caching: Heavy operations—such as reading JSON exception lists, calculating file hashes, or managing redirects—are cached using WordPress Transients or versioned options to minimize Disk I/O.

Adding New Modules

  1. Create a feature class in includes/features/class-your-module.php
  2. Add its definition to Core\Module_Registry::get_definitions()
  3. Register its settings in the module controller
  4. Add focused tests for defaults and any pure helpers

Local development checks

composer install
composer lint
composer phpcs
composer test
node --check assets/js/admin.js
bash -n build.sh
./build.sh

The pull-request workflow runs PHP syntax checks on PHP 7.4 through 8.5, coding standards, PHPUnit, JavaScript and shell syntax, version consistency, and distribution ZIP assertions.

Example module definition:

'your-module' => array(
    'title'       => __( 'Your Module', 'functionalities' ),
    'description' => __( 'Brief description', 'functionalities' ),
    'icon'        => 'dashicons-admin-generic',
),

See readme.txt for the full changelog.
