How to configure development settings on Drupal 8?

To configure development settings on Drupal 8, follow these steps:

1. Open your Drupal 8 site and navigate to the root directory where Drupal is installed.

1. Look for the “sites/default” folder and open the “settings.php” file.

1. In the “settings.php” file, scroll down to the bottom of the page, and locate the following line:

```

$settings[‘container_yamls’][] = DRUPAL_ROOT . ‘/sites/default/services.yml’;
```

1. Uncomment this line by removing the “#” at the beginning of the line.

1. Add the following lines of code below the “services.yml” line:

```

Enable debug mode.
$config[‘system.logging’][‘error_level’] = ‘verbose’;
$settings[‘cache’][‘bins’][‘dynamic_page_cache’] = ‘cache.backend.null’;
$settings[‘cache’][‘bins’][‘page’] = ‘cache.backend.null’;
$settings[‘cache’][‘bins’][‘render’] = ‘cache.backend.null’;
$settings[‘cache’][‘bins’][‘discovery’] = ‘cache.backend.memory’;
$settings[‘cache’][‘bins’][‘config’] = ‘cache.backend.memory’;
$settings[‘cache’][‘bins’][‘bootstrap’] = ‘cache.backend.memory’;
```

1. Save the changes and close the file.

1. Clear the cache by navigating to “Configuration” -> “Performance” in the Drupal admin interface and clicking the “Clear all caches” button.

After completing these steps, your Drupal site will be configured for development. This will allow for more detailed error messages and prevent caching issues that can occur during development.
