Article Ressources - Drupal 8  —  Differences between Configuration API & State API

This is the Gist repository for my article Drupal 8  —  Differences between Configuration API & State API.

Be aware that this article has been wrote for the Blog of Antistatique — Web Agency in Lausanne, Switzerland. A place where I work as Full Stack Web Developer.

Feel free to read it the full article on Medium or check it out on Antistatique.

config_api.php

<?php

// Typical usage of Configuration API

// Retrieve configuration as readonly
$config = \Drupal::config(‘mymodule.foo’);

// Get a value
$val = $config->get(‘key’);

/* The configuration object that was obtained and used in the previous examples
 * does not allow you to change configuration. If you want to change configuration,
 * you will instead need to get the configuration object
 * by making a call to getEditable() on the configuration factory:
 */
$config =\Drupal::service(‘config.factory’)->getEditable(‘mymodule.foo’);

// Set a value
$config->set(‘enabled’, 1);
// Save the configuration
$config->save();

// Delete a value
$config->clear(‘bar.boo’)->save();

state_api.php

<?php

// Typical usage of State API

// Get a value
$val = \Drupal::state()->get(‘key’);

// Get multiple key/value pairs
$pairs = \Drupal::state()->getMultiple($keys);

// Set a value
\Drupal::state()->set(‘key’,’value’);

// Set multiple values
\Drupal::state()->setMultiple($keyvalues);

// Delete a value
\Drupal::state()->delete(‘key’);
