Schema-Driven Form Builder
Schema-driven dynamic form builder with drag-and-drop composition and Zustand state
// Built with
react
typescript zustand
zod react-hook-form radix-ui tailwindcss01 Problem
Needed a reusable, schema-driven form system where form structure is defined by data rather than JSX — enabling dynamic field rendering, conditional logic, drag-and-drop builder UX, and shared form state without prop-drilling or complex context hierarchies.
03 Solution
Built a dynamic form builder using Next.js + Zustand + Zod + react-hook-form. Forms are described by JSON schema (field types, validation rules, conditional visibility) and rendered dynamically. A drag-and-drop FieldPalette lets users visually construct forms. Zustand manages per-form state independently, Zod enforces schema validation with real-time feedback.

04 Outcomes
Qualitative
- JSON schema → form render pipeline — structure from data, not JSX
- Drag-and-drop FieldPalette with live preview
- Conditional field visibility based on sibling field values
- Zustand slice-per-form for independent, persistent state isolation
- Real-time Zod validation with custom rule support
