Types

The most important core types are CreateFormOptions, FieldPathInput, FieldState, FormState, FormError, StandardSchemaV1, ValidationTrigger, FieldSchemaOptions, SetValueOptions, Form, and FormArray. Adapter packages also export their RegisterOptions alias and framework-specific return types.

import type {
  CreateFormOptions,
  FieldPathInput,
  FieldState,
  FormState,
  FormError,
  StandardSchemaV1,
} from '@ilokesto/form';
import type { RegisterOptions } from '@ilokesto/form/react';

Use these types at boundaries: shared form factories, custom hooks, reusable field components, and schema helpers. Avoid depending on internal normalized store keys unless a page explicitly documents them as observable through FormState. Public types describe the stable contract; implementation helpers can change without becoming part of application code.

Practical guidance

Keep this page near the source when you build abstractions. The reference describes what the package exposes, while guides show one way to compose those pieces. If a helper hides FieldPathInput, validation triggers, or array rebasing, document that helper with the same precision so future maintainers know whether strings, tuples, or stable keys are expected.
