sswr
A lightweight Svelte library implementing the stale-while-revalidate (SWR) data fetching strategy for reactive and efficient data fetching.
What is sswr?
SSWR is a Svelte library that implements the stale-while-revalidate (SWR) data fetching strategy. It provides a reactive and efficient way to fetch, cache, and automatically revalidate data in Svelte applications, enabling components to receive a constant stream of data updates while keeping the UI fast and responsive.
Svelte developers building dynamic, data-driven web applications that require efficient client-side data fetching with caching and real-time updates. It is particularly suited for projects using SvelteKit that need server-side rendering (SSR) compatibility.
Developers choose SSWR for its native integration with Svelte's reactivity system, offering a lightweight (2KB) solution with built-in cache, request deduplication, and features like dependent fetching, optimistic UI updates, and automatic revalidation on window focus or network changes. It provides fine-grained control with manual mutation and revalidation while maintaining simplicity and efficiency.
