## What it is
Formik is a popular open-source form library for React and React Native that manages form state, validation, and submission. It provides declarative components and hooks to handle values, errors, touched fields, and submission without external state management.

## Use cases
- build forms in react
- handle form validation in react
- manage form state with hooks
- create multi-step form wizards
- validate forms with yup schemas
- build forms in react native
- handle dynamic and array fields in forms

## When to choose
- you need battle-tested form state and validation handling in React or React Native
- you want schema-based validation with Yup integration
- you need form-level and field-level validation with sync/async support
- you want a small, incrementally adoptable library without Redux or MobX

## When to avoid
- you use a framework other than React or React Native
- you prefer fully uncontrolled forms with native HTML validation
- you want a newer signal-based or compiler-driven form solution
- you need extremely high-frequency input updates with minimal re-renders

## Facets
- artifact type: library
- maturity: stable
- function: form-handling, state-management, ui-components
- domain: web-development, frontend, mobile-development
- platform: cross-platform
