urql
Lightweight, extensible GraphQL client for React, Vue, and Svelte. Alternative to Apollo Client with a simpler, more predictable caching model. Two cache options: Document Cache (simple, per-query) and Graphcache (normalized, relational). Exchanges architecture makes urql highly customizable — add retries, auth, persistence, subscriptions as independent modules. Smaller bundle than Apollo Client with comparable features.

🔒 Security
Client-side GraphQL library. Auth via authExchange for secure token handling. HTTPS for all requests. MIT licensed.
⚡ Reliability
Best When
You want a simpler, lighter GraphQL client than Apollo with an extensible exchanges architecture and first-class support for Vue and Svelte.
Avoid When
You need the full Apollo ecosystem (Apollo Studio, Apollo Federation, extensive DevTools) — urql is lighter but Apollo has more enterprise tooling.
Use Cases
- • Query and mutate GraphQL APIs in React with automatic caching and request deduplication using a lighter Apollo alternative
- • Use the Graphcache normalized cache for relational data where cache updates propagate correctly across queries
- • Build real-time features using urql's subscription support over WebSockets or SSE
- • Implement offline-capable GraphQL apps using urql's persistence exchange for cache persistence
- • Integrate GraphQL in Vue or Svelte applications using urql's framework-specific adapters
Not For
- • Teams committed to the Apollo Client ecosystem — Apollo has more tooling, DevTools, and community resources
- • Complex cache update scenarios requiring many custom cache.updateQuery calls — Apollo Client offers more cache manipulation options
- • Server-side rendering with complex cache hydration — Next.js + Apollo has more SSR examples
Interface
Authentication
GraphQL client library — auth implemented via authExchange, a dedicated exchange for adding Authorization headers and handling token refresh.
Pricing
MIT licensed. Completely free. Maintained by Formidable Labs.
Agent Metadata
Known Gotchas
- ⚠ urql returns errors as values (result.error) rather than throwing — check both result.data AND result.error in every query handler
- ⚠ Document Cache (default) doesn't normalize — related data updates don't propagate; use Graphcache for normalized relational data
- ⚠ Exchanges must be composed in the correct order — requestPolicy exchange must come after authExchange in the pipeline
- ⚠ Stale-while-revalidate requires using 'cache-and-network' request policy — default 'cache-first' won't re-fetch unless cache is empty
- ⚠ urql Graphcache requires schema introspection for optimistic updates and schema-aware caching — set up schema from SDL or introspection endpoint
- ⚠ Subscriptions require a separate subscriptionExchange configuration with WebSocket or SSE transport — not automatic
