React component and hook for declarative promise resolution and data fetching. Makes it easy to handle every state of the asynchronous process, without assumptions about the shape of your data or the type of request. Use it with fetch, Axios or other data fetching libraries, even GraphQL.

  • Zero dependencies
  • Works with promises, async/await and the Fetch API
  • Now with experimental Suspense support
  • Choose between Render Props, Context-based helper components or the useAsync and useFetch hooks
  • Debug and develop every part of the loading sequence with the React Async DevTools
  • Provides convenient isPending, startedAt, finishedAt, et al metadata
  • Provides cancel and reload actions
  • Automatic re-run using watch or watchFn prop
  • Accepts onResolve, onReject and onCancel callbacks
  • Supports abortable fetch by providing an AbortController
  • Supports optimistic updates using setData
  • Supports server-side rendering through initialValue
  • Written in TypeScript, ships with type definitions
  • Works well in React Native too!
