Drupal Lazy Builders

Lazy builders defer rendering of dynamic/personalized content, enabling page caching while preserving dynamic elements.

When to Use

• Displaying user-specific data (name, cart, notifications)
• Content with session or user cache context
• Fixing UNCACHEABLE pages caused by max-age:0
• Improving authenticated user performance

How It Works

Page renders → Placeholder inserted → Page cached → 
Request → Cached page served → Placeholder replaced with fresh content
