How to Use Pattern Lab for Drupal 8 Theming

Patternlab is a dynamic organizational and prototyping tool for Drupal theming. By theming with pattern lab, your custom theme allows us to manage and build components in accordance with the required workflow using atomic design concepts1.

Using Pattern Lab for Drupal 8 Theming

Instead of rendering default Drupal templates, we can introduce pattern lab to include twig files using atomic concepts. It allows us to include external twig files by overriding the specific templates.

Steps for Installing Pattern Lab

  1. Install Node and NPM versions using NVM

    Initially we need to get the software packages from our Ubuntu repositories that will allow us to build source packages.

    sudo apt-get update
    sudo apt-get install build-essential libssl-dev

    Once these packages are installed, we can download NVM installation scripts from project’s github page.

    curl -sL

    Now inspect the installation script with nano


    Run the script with bash


    It will install the software into a subdirectory of your home directory at ~/.nvm. It will also add the necessary lines to your ~/.profile file to use the file. To gain access to the nvm functionality, we have to run the following command:

    source ~/.profile

    Now we have installed NVM, our next step is to install isolated Node.js versions. To find out the available version you can type

    nvm ls-remote

    In the output window, we can see the latest version as v8.9.4.We can install that by typing

    nvm  install 8.9.4

    Usually NVM will be switched to latest installed version or you can tell NVM to use the just downloaded version by typing

    nvm use 8.9.4

    The current version of Node can be checked by running the code

    node -v

    If you have multiplied Node-js version, you can see what is installed by typing

    nvm ls

    If you wish to set one of the version as default, you can type

    nvm alias default 
  2. Create Custom Theme (my_theme)

    NOTE: It is recommended to refer Emulsify (serves as a starter kit for Drupal 8 theme) for getting the exact folder structure and architecture of the Drupal 8 theme.

    Emulsify Drupal 8

    It is necessary to include the JS, CSS and the fonts of the dist folder into the libraries file in the custom theme.

  3. NPM Install

    Patternlab-npm-install.png Output: patternlab_packageinstall.png
  4. NPM- Start

    patternlab-npm-start.png Output: patternlab_emulsify.png

    When NPM start is completed, node packages will be installed to the custom theme and compiles the SASS files to CSS and JS added in the patterns, which is required for the generation of theme will be saved in the dist folder.

We have added a few new modules to our site recently. Drupal Technical StumbleThis Sean (not verified) access_time 18 Sep 2021 - 21:08 Hi there, I uploaded the files, enabled the modules to use SU, and now I see the link, but there is no icon... How can I fix this? Thanks, Sean webmaster access_time 18 Sep 2021 - 21:08 In reply to Icon doesn't show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where and leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but will redirect you to with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.

I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$$1 [L,R=301] When I go to, I get (as expected). However, when I go to (it's a Drupal site), I get a 404 thrown and the URL changes to Same thing with Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 18 Sep 2021 - 21:08 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 18 Sep 2021 - 21:08 This is definitely a good guide.
