Overview

The Headless CMS is built around three core concepts: Groups, Models, and Entries. Groups organize related models, models define content structure, and entries are the actual content instances.

Extension Points

You can extend the Headless CMS through three main approaches:

Builders - Programmatically define structure using:

  • GroupBuilder - Create and organize model groups
  • ModelBuilder - Define content models
  • FieldBuilder - Configure model fields

Event Handlers - React to lifecycle events:

  • Before/After Create, Update, Delete operations
  • Validation and authorization hooks
  • Custom business logic integration

Use Cases - Implement custom business logic:

  • Override default behavior
  • Add custom operations
  • Implement complex workflows

For detailed documentation on each extension point, see the specific sections on Builders, Event Handlers, and Use Cases.
