SWRV
A Vue Composition API library for remote data fetching using the stale-while-revalidate caching strategy.
What is SWRV?
swrv is a Vue.js library for remote data fetching that uses the stale-while-revalidate caching strategy. It provides a Composition API hook (`useSWRV`) to fetch, cache, and automatically revalidate data, ensuring UI components always have fast access to data while keeping it fresh. It solves the problem of managing asynchronous data state with built-in caching, deduplication, and error handling.
Vue.js developers building applications that require efficient, reactive data fetching with caching strategies, particularly those using the Composition API in Vue 3 or Vue 2.7+.
Developers choose swrv for its Vue-native reactivity, minimal API, and robust caching features like request deduplication, focus revalidation, and error retry. It offers a streamlined alternative to manual data fetching or state management libraries, inspired by SWR for React but designed specifically for Vue's ecosystem.
Overview
Stale-while-revalidate data fetching for Vue
Use Cases
Best For
- Fetching and caching API data in Vue 3 Composition API applications
- Implementing real-time data updates with background revalidation
- Reducing network requests through deduplication and caching
- Building offline-capable PWAs with localStorage cache support
- Managing dependent data fetching where one request relies on another
- Handling error states with stale cache fallbacks and automatic retries
Not Ideal For
- Vue.js projects requiring built-in server-side rendering (SSR) support for SEO or initial load
- Teams migrating from React's SWR who expect full feature parity and identical API behavior
- Applications needing complex, distributed caching systems (e.g., Redis) without custom implementation work
Pros & Cons
Pros
Returns Vue refs that automatically trigger UI updates when data changes, seamlessly integrating with the Composition API for reactive data streams.
Implements stale-while-revalidate with request deduplication and revalidation on focus, reducing network calls while ensuring fresh data as per the README features.
Works with any asynchronous fetcher function, defaulting to Fetch API, making it transport-agnostic and adaptable to various backends or libraries.
Allows data fetching that depends on other data, maximizing parallelism and handling serial dependencies efficiently without waterfalls.
Cons
Server-side rendering was explicitly removed in version 0.10.0, limiting its use in universal Vue applications and requiring additional setup for SSR.
Beyond basic localStorage adapters, implementing custom cache solutions requires deeper knowledge of internal cache structure, adding development overhead.
As a port of React's SWR, it may not keep pace with all features or updates, potentially causing inconsistencies for developers expecting exact parity.
