Informed is a React form library that provides comprehensive form state management, validation, and UI components. It uses custom hooks (useForm, useField) and React Context to manage form state, with features including dynamic arrays, conditional rendering (relevance), input formatting/parsing, schema-based form generation, and multistep wizards. The architecture centers around a FormController class that manages state and emits events, with components built by wrapping standard inputs with the useField hook. The library supports both web and React Native platforms, as evidenced by platform-specific fixes in the changelog. Key entry points are src/index.js (library) and vitedocs/main.jsx (documentation site).
