SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pydantic, zod, @tanstack/react-query, react-hook-form, @hookform/resolvers/zod, sonner, zod-prisma-types.

What problem does it solves? This Skill automates the complex process of integrating backend APIs with frontend UIs, ensuring type-safety, synchronized validation, and robust error handling. It eliminates common integration headaches, allowing for faster, more reliable full-stack feature development.

Core Features & Use Cases

  • Type-Safe API Contracts: Generates and synchronizes TypeScript types from Python Pydantic schemas or leverages native Prisma types for Next.js Server Actions.
  • Synchronized Validation: Ensures frontend (Zod) and backend (Pydantic/Prisma) validations are identical, providing consistent user feedback and security.
  • Full-Stack Form Integration: Connects shadcn/ui forms to backend endpoints (FastAPI or Server Actions) with built-in loading, error, and optimistic update patterns.
  • Use Case: When building a new user registration form, this skill will create the backend API endpoint, define the data models, generate the frontend form with validation, and handle submission logic, all with type-safety.

Quick Start

Create a full-stack feature to add new tasks, ensuring type-safe communication between the frontend form and the backend API.

Frequently Asked Questions about integration

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I keep frontend and backend validation in sync between Next.js and FastAPI?▼

Type-safe API contracts synchronize validation across Zod (frontend) and Pydantic (backend), ensuring identical rules. This Skill bridges the two by generating TypeScript types from Pydantic schemas or native Prisma types, eliminating validation mismatches and providing consistent user feedback.

Can I use Prisma types directly in my Next.js forms without duplicating schemas?▼

Yes. This Skill leverages Prisma types natively for Next.js Server Actions, eliminating schema duplication. Types flow directly from your database model into frontend forms via zod-prisma-types, ensuring your form validation matches your database structure.

What's the best way to connect a shadcn form to a FastAPI backend with type safety?▼

This Skill generates type-safe form integration by linking shadcn/ui forms to FastAPI endpoints through mirrored Pydantic and Zod schemas. It handles submission logic, loading states, error handling, and optimistic updates automatically, maintaining type safety end-to-end.

How do I handle loading states and errors when integrating frontend forms with backend APIs?▼

This Skill provides standardized error handling and loading-state management patterns for form submissions. It integrates react-hook-form with @tanstack/react-query and sonner notifications, delivering consistent user feedback across both FastAPI and Next.js Server Actions paths.

Does this work for both FastAPI REST endpoints and Next.js Server Actions?▼

Yes. This Skill supports full-stack features across both Path A (Python FastAPI with React) and Path B (Next.js Server Actions), using REST or RPC-like communication patterns with identical type-safety and validation guarantees.

What prerequisites do I need before building type-safe API integrations?▼

You need a defined data model (Pydantic for FastAPI or Prisma for Next.js), frontend form framework (shadcn/ui with react-hook-form), and familiarity with TypeScript and your chosen backend. This Skill generates the integration layer; models and forms must exist first.
