77 base assets

[JulesKhong]

77 This PR removes base-assets files from thinkwp-starter-theme, and adds a composer script to bring them back in from the thinkshout/base-assets repo.

This PR adds a new composer script file to the theme itself. This also works if we want to add the script to the top-level composer.json file instead. In that case, the script would need to be removed from this PR.

If adding it to the top level composer.json file, the script needs to be changed slightly, and the theme name would need to use a variable instead of pointing to think-friends:

"scripts": {
    "scaffold": [
      "git clone git@github.com:thinkshout/base-assets.git",
      "mv base-assets/scaffold/* web/wp-content/themes/custom/think-friends/",
      "rm -rf base-assets"
    ]
  }

To test:

• pull in this branch
• From the theme, run composer scaffold
• Expect all files and directories in scaffold from base-assets to appear in the theme in the correct locations.
• Run npm install, and npm run build
• Expect /style-guide to be populated with base build atoms, molecules and blocks.
• Expect the site nav and footer to be populated with the base build styles, including mobile nav

Known bugs

• [x] Base build blocks aren't appearing on the /style-guide page.
