CSS build

The build toolchain requires Node.js ≥ 22.13 and Gulp CLI ≥ 3.

npm install          # install dependencies once
gulp                 # production build (minified, PurgeCSS)
gulp dev             # watcher for day-to-day development

gulp dev also clears the shop's Smarty tmp/ on template and translation changes. Run the shop in dev mode (admin → Theme settings → disable production mode) while developing so the browser loads unminified assets.

To rebuild only the CSS without the full gulp pipeline:

cd out/o3-theme/src/css
npx sass --style=compressed --no-source-map main.css main.min.css

Child themes

O3-Theme is designed to be extended via child themes. Set parentTheme => 'o3-theme' in the child theme's theme.php. O3-Shop resolves templates and assets from the child theme first, then o3-theme, so only files that actually differ need to be present in the child theme.

Clearing the Smarty cache

docker exec <shop-container> bash -c "rm -rf /var/www/html/source/tmp/smarty/"
