D10 | Custom Theme - Dart SASS + Node 16

1. Create a fresh Drupal 10 project.

   1. Two options, Download Drupal 10 directly: https://www.drupal.org/project/drupal/releases/10.0.0

   2. Alternatively, use Composer https://www.drupal.org/docs/develop/using-composer/manage-dependencies

      1. If you have composer globally:

         composer create-project drupal/recommended-project my_site_name_dir 

      2. Change my_site_name_dir to an appropriate name for your project.

2. Create a new, custom Drupal Theme.

   1. Run this command from your project’s root:

      php core/scripts/drupal generate-theme my_new_theme

      1. Change my_new_theme to an appropriate name for your project.

   2. Otherwise, download or create your own theme from scratch.
      

3. Update composer.json file, in project root.

   1. Ensure to include drush if you would like to use it - "drush/drush": "^11.4" . You can also run composer require drush/drush
      

4. Create a package.json file, in theme root.

   1. Add what you need. Here’s a helpful example with explanation: https://www.hook42.com/blog/nodejs-version-control-drupal-themes

   2. Run the following, suggested commands:

      1. npm cache clean --force

      2. nvm ls
         Prints the node versions installed on your machine & the current node version you're using.

      3. nvm use 16

      4. npm install

      5. npm cache clean --force

   3. If you run into a problem, and want to try again:

      1. rm -r node_modules
         This will remove the node_modules folder in your repository. If you are using Webpack, you can also remove the dist folder using rm -r dist and re-build your repository.
         

   4. If you are updating an existing Node 14 project, that uses npm node-sass, you will need to make a few changes before updating to Node 16 and npm sass.

      1. What is the difference? Read these first - https://www.npmjs.com/package/node-sass/v/7.0.1 vs https://www.npmjs.com/package/sass

      2. Node-Sass
         Warning: LibSass and Node Sass are deprecated. While they will continue to receive maintenance releases indefinitely, there are no plans to add additional features or compatibility with any new CSS or Sass features. Projects that still use it should move onto Dart Sass.
         
         Are you running a M1 mac? ARM64 isn't supported by any version of node-sass right now.

         • If you try to run npm install will error out. Instead, run these first while also reviewing from the start of this section:

           • npm uninstall node-sass

           • npm install sass or npm i sass --save or npm install node-sass@npm:sass
             

5. Create a Lando, or DDev project.
