## What it is
Reactive Data Client is a TypeScript async state management library for React, React Native, Vue, and Next.js that provides declarative, schema-driven access to REST, GraphQL, WebSocket, and SSE data with a normalized cache. It keeps all data usages consistent through atomic mutations, referential equality guarantees, and hooks like useSuspense() and useLive().

## Use cases
- manage async state in react apps without manual reducers
- fetch and cache rest api data with normalization
- consume graphql and websocket streams alongside rest endpoints
- keep lists and nested entities consistent after create update delete mutations
- server-side render data with nextjs
- build react native or expo apps with shared data layer
- render live updating data like stock tickers via sse or polling

## When to choose
- your app has complex relational data from a relational-database-backed api
- you want normalized caching with automatic consistency across components
- you need to combine rest, graphql, and streaming protocols in one store
- you want suspense-based data fetching with minimal boilerplate

## When to avoid
- your app has mostly static content or simple key-value state
- you need a general-purpose client state store for ui-only state like forms or theme
- your team is already committed to another data layer like react-query or apollo and migration cost outweighs benefits
