Guidelines

Theme Development

• Use Shopify CLI for theme development: shopify theme dev for live preview
• Structure themes with sections and blocks for Online Store 2.0 compatibility
• Define schema settings in sections for merchant customization
• Use {% render %} for snippets, {% section %} for dynamic sections
• Implement lazy loading for images: loading="lazy" and {% image_tag %}
• Use Liquid filters for data transformation: money, date, url_for_vendor
• Avoid deep nesting in Liquid - extract complex logic to snippets
• Implement proper error handling with {% if %} checks for object existence
• Use {% liquid %} tag for cleaner multi-line Liquid code blocks
• Define metafields in config/settings_schema.json for custom data

Liquid Templating

• Access objects: product, collection, cart, customer, shop, page_title
• Use filters for formatting: {{ product.price | money }}, {{ article.published_at | date: '%B %d, %Y' }}
• Implement conditionals: {% if %}, {% elsif %}, {% else %}, {% unless %}
• Loop through collections: {% for product in collection.products %}
• Use {% paginate %} for large collections with proper page size
• Implement {% form %} tags for cart, contact, and customer forms
• Use {% section %} for dynamic sections in JSON templates
• Leverage {% render %} with parameters for reusable snippets
• Access metafields: {{ product.metafields.custom.field_name }}

Section Schema

• Define section settings with proper input types: text, textarea, richtext, image_picker, url, range, checkbox, select, radio
