How to Automatically Consume RESTful APIs in Your Frontend
Since the OpenAPI can effectively describe our resources, we can reuse it to generate a dummy server that can be later used for development and testing purposes without bootstrapping any actual services. There some tools available that can help us with this task, such as Prism, OpenAPI Mock, OpenAPI Backend and the MSW library we have already seen.

GraphQL vs REST: 18 Claims Fact-Checked with Primary Sources (2026)
Historically, measurements around 40–45 KB gzipped were reasonable for older Apollo Client bundles , but recent v4.x releases have reduced bundle size and made features more modular. Regardless, that is not a cost of GraphQL itself. The same concern exists for feature‑rich REST clients like SWR or TanStack Query . It is a misleading comparison because both REST and GraphQL can be implemented with nothing more than fetch(). Therefore, the theoretical baseline for both styles is 0 KB.

Effective Patterns for Shared State Management in React
For server-state (data fetched from an API), tools like React Query or SWR shine. They handle caching, refetching, and error states without needing to push API responses into Redux.
