SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Async data in Reactor is managed with dedicated hooks for single fetch, writes with optimistic updates, cursor-based pagination, and a bubble-up fallback, eliminating manual cancellation and scattered state management.

Core Features & Use Cases

  • UseResource: fetch a single resource and expose AsyncValue<T> with Loading, Data, Error, and Reloading states.
  • UseMutation: perform server mutations with optimistic updates and a stable Mutation handle.
  • UseInfiniteResource: cursor-based pagination with page loading, caching, retry, and refresh capabilities.
  • Pending: bubble-up fallback that aggregates loading across nested resources.

Quick Start

Create a Reactor component that uses UseResource to fetch data and UseMutation to update it.

FAQPage Schema
How do I manage asynchronous data fetching in WinUI without scattered state management?▼

Manage asynchronous data in WinUI using dedicated hooks like UseResource to fetch single resources and expose AsyncValue<T> states, eliminating manual cancellation and scattered state management.

What is the best way to handle server mutations with optimistic updates in Reactor?▼

Handle server mutations in Reactor using the UseMutation hook, which provides a stable Mutation handle to perform writes with optimistic updates and manage server state efficiently.

How does cursor-based pagination work for large collections in Reactor?▼

Cursor-based pagination in Reactor uses the UseInfiniteResource hook to load pages sequentially, providing built-in caching, retry logic, and refresh capabilities for large collections.

Can I configure caching and retry behavior for async data in Reactor?▼

Configure caching and retry behavior in Reactor using optional ResourceOptions, allowing you to set StaleTime, CacheTime, RetryCount, and RefetchOnMount for async data fetching.

How do I aggregate loading states across nested async resources in Reactor?▼

Aggregate loading states across nested async resources in Reactor using the Pending bubble-up fallback, which automatically consolidates loading indicators for nested components.

Do I need CancellationToken-aware fetchers for async data flows in Reactor?▼

Reactor enforces CancellationToken-aware fetchers for async data flows, ensuring that resource fetching, memoized dependencies, and data cancellation are handled safely.
