During December 2025, Ofek contributed to the TanStack/query repository by enhancing documentation for the PersistQueryClientProvider’s server-side rendering (SSR) persistence. Focusing on React and server-side rendering, Ofek clarified how to use the provider with SSR streaming, addressing common integration pitfalls such as persisting promises or unsuccessful queries. The work incorporated feedback from code reviews, ensuring the documentation aligned with real-world usage and reduced the risk of erroneous persistence. By improving Markdown-based guides, Ofek helped developers avoid inconsistent server-rendered data and strengthened SSR caching reliability. This targeted documentation update improved onboarding and provided clearer guidance for integrating SSR persistence features.
