3. Development

All source files for CSS and JavaScript are located in the build/ directory.

Available Commands

Run these commands from the theme root directory:

Development Workflow

Start the watcher:

gulp dev

During development, make sure production-mode is disabled. Only then will you be able to view the source maps and unminified assets.

💡 Tip: Use the mode-tool, which shows you in the frontend which mode the shop is in. You can activate it in the theme settings.

The watcher monitors:

• build/js/**/*.js → Rebuilds JavaScript bundles
• build/scss/**/*.scss → Rebuilds CSS
• **/*.tpl → Clears OXID TMP directory
• Application/translations/**/*.php → Clears OXID TMP directory

Production build:

gulp

This will:

• Minify JavaScript and CSS
• Remove unused CSS with PurgeCSS
• Optimize assets for production

PurgeCSS Safelist

PurgeCSS removes unused CSS classes. If you dynamically generate class names in JavaScript or templates, add them to the safelist.

Example dynamic classes:

{* Template with dynamic class *}
<div class="[{$type}]-view"></div>

Add to safelist in gulpfile.js:

safelist: [
    'grid-view',    // Add your dynamic classes here
    'line-view',
    /^custom-/,        // Or use patterns
]

Location: Line ~81 in gulpfile.js in the PurgeCSS configuration.

5. Asset Integration

JavaScript

• Main JS bundle:
  <DOCUMENT_ROOT>/source/Application/views/o3-theme/build/js/main.bundle.js
• import new scripts here to include them in the main JS.
• Files in build/js/widgets/ are standalone and must be explicitly loaded in templates: [{oxscript include="js/widgets/checkagb.js" priority=10}]

JavaScript from modules can also be integrated into main.bundle.js. Descriptions and examples can be found in the bundle-file.

SCSS

• Main SCSS bundle:
  <DOCUMENT_ROOT>/source/Application/views/o3-theme/build/scss/main.bundle.scss
• @import new styles here to include them globally.

CSS/SCSS from the modules can also be integrated into main.bundle.scss. Descriptions and examples can be found in the bundle-file.

6. jQuery

• This theme uses Bootstrap 5.3.8, which means that vanilla JS is used instead of jQuery.
• If jQuery is absolutely necessary, enable it in theme settings (same version as theme wave).
• Deprecation warnings during build are harmless and will disappear when updating Bootstrap.

7. Compatibility with PayPal

The PayPal module checks the active theme ID in one of its templates: [{if $oViewConf->getActiveTheme()=='flow'}] Change 'flow' to 'o3-theme' for compatibility.
