What problem does it solve?

This skill provides a structured approach to connecting UI components with backend services by using a reactive query layer that simplifies data fetching, caching, and state management.

Core Features & Use Cases

  • Call services with injected settings/config to decouple business logic from environment
  • Transform service errors into user-facing error types for stable UI behavior
  • Manage TanStack Query cache for optimistic updates and consistent data
  • Support dual interfaces: reactive (.options) for components and imperative (.execute()) for workflows
  • Runtime dependency injection to select service implementations based on settings

Quick Start

Define your queries and mutations with defineQuery/defineMutation using runtime service selection to enable reactive UI and imperative workflows.
