React Query
React Query is an asynchronous state management library and data fetching orchestrator designed to fetch, cache, and synchronize server state in web applications. It functions as a server-state cache manager that handles asynchronous data requests to keep local application state in sync with a remote server.
The library implements a stale-while-revalidate cache pattern, which provides immediate access to cached data while triggering background updates to maintain consistency. It further supports optimistic user interface updates, allowing the interface to change immediately during data mutations while syncing with the server in the background.
The utility covers a broad range of capabilities including remote data mutation, web data caching, and the management of pagination and dependent queries. It also provides tools for optimizing data loading and synchronizing server state across various JavaScript and TypeScript UI frameworks.
Features
- Server State Managers - Functions as a server-state manager that synchronizes remote data with local application state.
- Stale-While-Revalidate Strategies - Implements a stale-while-revalidate cache pattern to provide immediate data access while triggering background updates.
- Cache Revalidation - Updates server information and automatically refreshes the local cache to maintain data consistency across the UI.
- Asynchronous Data Fetching - Retrieves remote data and manages its lifecycle as asynchronous state to keep the user interface in sync.
- Asynchronous State Managers - Manages remote server data as asynchronous state to ensure the user interface remains synchronized.
- Asynchronous Data Caching - Caches the results of asynchronous network operations using unique keys to reduce redundant requests.
- Data Fetching Orchestrators - Orchestrates mutations, pagination, and dependent queries to synchronize local state with a remote server.
- Stale-While-Revalidate - Implements the stale-while-revalidate pattern to provide immediate cached data while triggering background updates.
- Optimistic Updates - Provides a system to update the user interface immediately during mutations and synchronize changes with the server in the background.
- Cache Mutation Utilities - Provides utilities for updating and revalidating local data caches during the mutation lifecycle.
- Cache Key Generators - Generates unique cache keys using serialized arrays or strings for efficient retrieval of asynchronous data.
- Cache Garbage Collection - Implements automatic removal of unused cache entries to prevent memory leaks in long-running sessions.
- State Synchronization Patterns - Uses an observer-based pattern to trigger automatic data refetches when window focus or connectivity changes.
- Dependency Resolvers - Defers network requests until prerequisite data dependencies are resolved to ensure components are fully populated.
- Perceived Performance Optimizations - Optimizes perceived performance through prefetching resources and providing immediate feedback via optimistic updates.
- State Management Utilities - Provides state management utilities to handle asynchronous data lifecycles across multiple JavaScript and TypeScript frameworks.
- Web Caching - Stores network responses locally to reduce redundant API calls and improve application loading speeds.
- Data Fetching Utilities - Provides utilities for managing network requests, preloading, and caching across various UI frameworks.
- Optimistic UI Updates - Updates the user interface immediately during mutations and synchronizes with the server in the background.
- API Clients and Utilities - Data fetching and caching for React.
- Data Fetching - Fetch, cache, and update asynchronous data.
- React Ecosystem - Hooks-based library for fetching, caching, and updating asynchronous data.
- State Management - Powerful asynchronous state management for React applications.
