Core Validation Groups

Purpose

Groups let applications validate and summarize a logical section instead of the entire model.

const personalGroup = {
  name: 'personalGroup',
  policies: ['personal'],
  formGroups: ['personal'],
  fields: ['personal.firstName', 'personal.lastName', 'personal.email']
};

Use cases

• Multi-section checkout flows.
• Tabbed forms.
• Generated performance sections.
• Save-as-draft workflows.
• Section-level summaries.

Group status

Adapters usually write status back to the model:

type GroupStatus = {
  isValid: boolean;
  isInValid: boolean;
  isEvaluated?: boolean;
  errors?: Array<{ propertyName: string; error: { message: string } }>;
};

Best practices

Keep names stable, keep fields aligned with generated policies, and clear group status when removing dynamic fields.
