# Enhancing Drupal front end performance through Pattern Lab

Component-driven theming is becoming widely popular today because of various reasons. The most significant being reusability and portability of components. Pattern lab is a front-end framework that uses an atomic design architecture to implement a component-based design. In this article, we will discuss more about Pattern Lab and how you can enhance your [Drupal frontend performance](https://www.specbee.com/blogs/drupal-8-website-advanced-css-js-aggregation-brief-guide-improving-front-end-performance) with it.

## What is Pattern Lab?

Think of Pattern Lab as an application that can help you organize your UI components in a pattern-driven approach. It is basically a static site generator that binds together all the UI components together. Pattern lab uses atomic design to accelerate the process of creating modular designs. It starts out really basic and gets more complex as you move up the ladder.

Let’s breakdown these visual building blocks:

**Atoms:** They are the most basic building blocks of your design. For example, UI elements like buttons, search fields, form elements, labels.

**Molecules:** They are groups of atoms that work together to perform a particular action. For example, a search navigation that involves a combination of atoms like a search button, a search field and a label.

**Organisms:** Organisms are molecules and atoms grouped together to define sections of the application. They’re more complex and have more interactions. For example, a header, a footer or a related blog post section.

**Templates:** Groups of Organisms form Templates. They are placeholders for organisms. For example, a blog page template, login page template or a shopping cart page template.

**Pages:** When you combine a template with real content, you get a page.

## Why should you use Pattern Lab?

Patten Lab makes frontend developers work an absolute pleasure. This is because it allows rapid design prototyping with demonstrable interface and interactivity.

It allows developers to maintain code consistency, implement and leverage reusable components and allows multiple developers to work at the same time. All of these benefits help in easy maintenance of the code.

In terms of Drupal, frontend developers can start their work independently without the dependency on Drupal development. We can work faster and with more consistency than ever before.

## Patten Lab with Drupal

Integrating Pattern Lab with Drupal has many benefits and can improve and fasten frontend development. Thanks to the Drupal community, we now have a contributed theme [Emulsify Drupal](https://www.drupal.org/project/emulsify_drupal) that comes with inbuilt the Pattern Lab architecture. This reduces the extra development effort of achieving a Pattern Lab integration.

## Creating a Heading atom in Pattern Lab

For a better understanding of implementing Pattern Lab in Drupal, let’s take an example of creating a Heading atom and integrating it in Drupal Twig template.

### Heading atom directory

 ![Heading atom directory](https://www.specbee.com/sites/default/files/styles/large/public/migrated/atom_directory_0.png.avif?itok=5cx09o49)

 

 In the atom directory we will have 3 required files.

**\_heading.twig :** The heading markup will go in this file
**\_hading.scss :** This is for heading style
**heading.yml :** This is for static data to be passed in twig

### Heading atom Twig

![heading twig](https://www.specbee.com/sites/default/files/inline-images/heading-twig.png)*\_heading.twig*

In Heading twig, we can add the element markup with all the required attributes as variable. We can pass data from yml file or drupal field data with these variables.

**Heading.yml / Heading.json**

![heading json](https://www.specbee.com/sites/default/files/inline-images/heading-json.png)*heading.json*

This is an example of a json file containing static data for the variable available in the \_heading.twig file.

## Integrating Heading atom in Drupal template with field values

Here, we will be overriding the page template and integrating it with the heading atom.

![barkit page](https://www.specbee.com/sites/default/files/inline-images/barkit-page.png)*Default bartik page-title.html.twig*

![page title](https://www.specbee.com/sites/default/files/inline-images/page-title.png)*Pattern Lab Heading atom integrated in page-title.html.twig*

Here, in **page-title.html.twig**, instead of the default H1 element we are importing the heading atom as reusable element and adding Drupal field value to the defined variable in the heading atom - **heading\_level** and **heading**.

Using the same pattern, we can create engaging Drupal websites using Pattern Lab.

I hope this article encourages you to start using Pattern Lab with Drupal using the Emulsify Drupal theme and play around with atoms, molecules, organisms, templates and pages to create compelling websites.
