## What it is
@rc-component/form (formerly rc-field-form) is a performance-first React form state management library with field-level subscriptions, rule-based validation, nested names, lists, and dependency control. It provides Form, Field, List, FormProvider, useForm, and useWatch APIs and works with both React DOM and React Native, powering Ant Design's Form component.

## Use cases
- manage form state in react with fine-grained re-renders
- validate form fields with rules
- build dynamic form lists with add and remove rows
- watch specific field values with hooks
- create forms that work in react native
- handle dependent fields that update based on other fields
- build the form layer for a component library

## When to choose
- you need performant forms where only subscribed fields re-render
- you are building or extending Ant Design style forms
- you need nested field names, lists, and field dependencies
- you want a framework-agnostic form state model usable in React Native

## When to avoid
- you want a batteries-included UI form library with prebuilt inputs
- your forms are trivial and uncontrolled inputs suffice
- you prefer schema-driven form generation out of the box
