react-cache

library2.0.0-alpha.1jsnpmunverified

An experimental caching library for React applications, designed to work with concurrent mode and Suspense for data fetching. Version 2.0.0-alpha.1, published by Facebook for demonstration purposes. It provides a basic cache API (unstable_createResource) that integrates with React's experimental features. Not intended for production use; the API is unstable and likely to change. It has no other key differentiators as it's a reference implementation.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

unstable_createResource

✓ import { unstable_createResource } from 'react-cache'

✗ const unstable_createResource = require('react-cache').unstable_createResource

ESM module; CommonJS require works but is atypical for React packages.

unstable_createCache

✓ import { unstable_createCache } from 'react-cache'

Undocumented but exported; may change.

default import (not available)

✓ import * as ReactCache from 'react-cache'

✗ import ReactCache from 'react-cache'

No default export; use namespace import.

Creates a resource for data fetching using Suspense-compatible cache.

import React from 'react'; import { unstable_createResource } from 'react-cache'; const resource = unstable_createResource((id) => { return fetch(`https://api.example.com/data/${id}`).then(res => res.json()); }); function MyComponent({ id }) { const data = resource.read(id); return <div>{data.name}</div>; }
