It's often useful to pass dynamically calculated values from the server to the client in order to make them available to your front-end JavaScript. Your JavaScript might need to know something particular about the user currently visiting the site or the value of a particular configuration variable. In this tutorial, we'll look at how Drupal can pass these values from the PHP code that executes during a page load to the front-end JavaScript in your theme.
In order to do this, we'll need to:
- Explain how drupalSettings bridges the gap between PHP and JavaScript
- Generate values for settings in PHP and make them available to JavaScript
- Make use of PHP generated settings within your JavaScript code
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously.

Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
