Description

React Hooks for Remote Data Fetching

Overview

SWR is a library that provides React hooks to simplify remote data fetching.

Naming Origin

The acronym “SWR” comes from stale‑while‑revalidate, an HTTP cache invalidation strategy detailed in RFC 5861.

Operation Flow

1. Stale – The hook first supplies cached data, which may be outdated.
2. Revalidate – It then initiates a network request to fetch fresh data.
3. Update – Once the new data arrives, the hook updates the component with the latest information.
