URQL GraphQL Data Fetching FAQs

Question 1

What are the common pitfalls when using URQL v6?

Accepted Answer

A major change in v6 is the default use of GET for small queries. If your server only supports POST, you must explicitly set the preferGetMethod option to false to avoid request failures.

Question 2

What is the importance of exchange order in URQL?

Accepted Answer

Exchange order is critical because operations flow through them sequentially. Synchronous exchanges like cacheExchange must always come before asynchronous ones like fetchExchange to ensure cached data is returned without unnecessary network requests.

Question 3

How does URQL handle real-time updates?

Accepted Answer

It utilizes a subscriptionExchange combined with transport libraries like graphql-ws to manage persistent WebSocket connections, allowing components to reactively update as data changes on the server.

Question 4

Why use URQL over Apollo Client?

Accepted Answer

URQL is significantly smaller (~12KB vs ~30KB+), offers a more flexible exchange-based middleware architecture, and is easier to customize for specific project needs while providing similar core functionality.

Question 5

Does this skill support normalized caching?

Accepted Answer

Yes, it includes detailed patterns for Graphcache, which provides full entity normalization, optimistic updates, and manual cache invalidation for complex data structures.
