dev_mode

Development mode makes it easy to enable developer friendly settings on your Drupal site, so you don't have to constantly clear the cache and/or hard-reload your browser.

Do not enable on production sites!

Enable this module and it will:

• Disable twig caching.
• Turn on twig debug/template suggestions.
• Disable most Drupal caches.
• Disable JS and CSS aggregation.
• Disable browser level caching.
• Turn on verbose error logging.

Disable this module and it will:

• Restore your previous settings.

Install

Install with composer:

composer require --dev drupal/dev_mode

Enable with drush:

drush en dev_mode

1. Enable module (like above) to activate development mode on your Drupal site.
2. Module will attempt to include settings.dev_mode.php in your settings.php, if it's writeable. If not, you will need to add in manually. See below for example.
3. Check logs after install to insure all went well.

Settings file

Module will attempt to write to settings.php, but if not writeable,
please add the following to the end of settings.php file:

/**
* Development mode settings.
*/
if (file_exists($app_root . '/modules/contrib/dev_mode/settings.dev_mode.php')) {
  include $app_root . '/modules/contrib/dev_mode/settings.dev_mode.php';
}
