BaseFieldInput

Defined in: packages/core/src/fields/baseTypes.ts:183

Properties shared by all field types.

Every field type (text, number, checkbox, etc.) extends this interface with its own type discriminant and type-specific options. These base properties control labeling, validation, admin UI behavior, and database indexing.

Defaults applied by field config functions:

{
  label:    "",     // inferred from the field key by defineCollection
  required: false,  // field is optional in the database schema
  admin:    { ... } // see FieldAdminConfigInput for admin defaults
}

See

BaseField for the resolved type after defaults are applied
