Compile Tailwind CSS for Hyvä Themes

Compiles Tailwind CSS for Hyvä themes in Magento 2. Handles both production builds and development watch mode.

Step 1: Detect Environment & Set Command Wrapper

Use the hyva-exec-shell-cmd skill to detect the environment and determine the appropriate command wrapper. All npm commands below show the core command; wrap them according to the detected environment.

Step 2: Identify Theme

If no theme path provided, invoke the hyva-theme-list skill to discover available themes. Filter the results to only include themes in app/design/frontend/ by default. Themes in vendor/hyva-themes/ require explicit user request.

If no themes found: Inform the user that no Hyvä themes with Tailwind configuration were found in app/design/frontend/. Ask if they want to check vendor/hyva-themes/ instead, or if they need to create a child theme first using the hyva-child-theme skill.

Step 3: Install Dependencies & Build

Default to production build unless user explicitly requests “watch”, “watch mode”, or “live reload”.

# Install deps only if node_modules missing
if [ ! -d "<theme-path>/web/tailwind/node_modules" ]; then
  cd <theme-path>/web/tailwind && npm ci
fi

# Production build (default)
cd <theme-path>/web/tailwind && npm run build

# OR watch mode (only if explicitly requested)
cd <theme-path>/web/tailwind && npm run watch

Step 4: Verify Output

Compiled CSS location: <theme-path>/web/css/styles.css

Confirm the file was updated by checking its modification time.

Troubleshooting

• Missing node_modules: Run npm ci
• Outdated styles: Clear browser cache; in production mode run bin/magento setup:static-content:deploy
