Schema basics

Define the data shapes used by templates.

Schema basics

Templates rely on schemas to declare the data they expect. Schemas are simple JSON-like structures with types and validation.

Field types

  • string, number, boolean
  • object (nested fields)
  • array (list of objects or primitives)
  • image, richtext

Validation

  • Define required fields and basic constraints (min/max length, regex).

Tip for editors

Keep schemas minimal and prefer nested objects for repeated groups.
