## What it is
swrv is a Vue Composition API library for remote data fetching using the stale-while-revalidate caching strategy. It serves cached data immediately, revalidates in the background, and provides features like polling, revalidation on focus, request deduplication, and error retry.

## Use cases
- fetch remote data in Vue components with automatic caching
- show stale data instantly while revalidating in the background
- poll an API at intervals to keep the UI up to date
- deduplicate duplicate in-flight requests across components
- refetch data when the window regains focus
- retry failed requests with stale-if-error fallback
- plug in a custom cache like localStorage

## When to avoid
- you need SSR support, which was removed as of version 0.10.0
- your project uses React (use the swr library instead)
- you need a full state management solution rather than a data-fetching hook
- you're on Vue 2.6 or below and can't use an older release
