Handle promises with ease.

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!
