    Hello My name is Coen Jacobs Developer at Radish Concepts

    Jumped out of the bubble Still do WordPress projects
  2. 4.

    Composer “Composer is a tool for dependency management in PHP.

    It allows you to declare the libraries your project depends on and it will manage (install/ update) them for you.”
  3. 5.

    What does Composer do? » Load your dependencies » Loads

    dependencies of your dependencies » And so on... » Offers a powerful autoloader » Inspired by npm and bundler » Made by Jordi Boggiano
  4. 8.

    Manual loading... require_once 'classes/class-core.php'; require_once 'includes/wpseo-local-functions.php'; require_once 'includes/ajax-functions.php'; require_once 'classes/class-core.php';

    require_once 'classes/class-admin.php'; require_once 'classes/class-admin-wrappers.php'; require_once 'classes/class-metaboxes.php'; require_once 'classes/class-frontend.php'; require_once 'classes/class-storelocator.php'; require_once 'classes/class-taxonomy.php';
  5. 9.

    Classmap: "autoload": { "classmap": [ "includes" ] } PSR-4: "autoload":

    { "psr-4": {"Never5\\ WPNotificationCenter\\": "src/"} }
  6. 23.

    Plugin A: "require": { "wpupdatephp/wp-update-php": "~1.0" } Plugin B: "require":

    { "wpupdatephp/wp-update-php": "~1.0" } Solution: Install WPupdatePHP version 1.0.0, right?
  7. 29.

    In the example, 1.0.0 was loaded the plugin bundling 1.1.0,

    assumes that version is there Fatal error: Call to undefined method
  8. 38.

    What if you can't? Want to bundle something with your

    plugin What if you can't add your site to Composer?
  9. 39.
  10. 41.

    Creates a master composer.json » loop through wp-content/plugins/ » check

    for composer.json file » run wikimedia/composer-merge-plugin » composer install » installed in wp-content/vendor/ At least in theory, this works
