MobX Formkit is a reactive form state management library built on MobX observables with a UI-agnostic core. It provides declarative field definitions, extensible validation via 8 plugins, nested fields, event hooks, and bindings for React, Vue 3, Lit, Angular, Solid, and vanilla JS.

Use cases

• manage complex form state in react with mobx
• validate forms with zod or yup schemas
• handle deeply nested form fields and arrays
• build multi-step form wizards
• share one form definition across react and vue
• bind form fields to material ui or ant design components

When to choose

• you already use MobX and want reactive form state
• you need UI-framework-agnostic form logic reusable across renderers
• you need pluggable, mixable validation drivers (Zod, Joi, Yup, AJV, etc.)
• you need deeply nested fields, dynamic arrays, and serialization
• bundle size matters (~8KB gzip, tree-shakeable, SSR-friendly)

When to avoid

• your project doesn't use MobX and you don't want the dependency
• you want a batteries-included React form library with built-in UI components
• you need a tiny form with minimal setup where a simpler hook-based library suffices
