React Query API Design – Lessons Learned
Top Content

I'm super excited to be here today, giving my first live talk at an in-person conference. Dominik, the maintainer of React Query, walks through the API design decisions, including success stories, trade-offs, and mistakes. Tener Linsley designed React Query's medium-sized query API to be minimal, intuitive, powerful, and flexible. Major versions in open source require marketing efforts, but not primarily for adding new features. TypeScript is crucial for building projects and managing user demands in open source can be challenging. The addition of the max pages option improved performance and avoided unnecessary refetches. Inversion of control gives users flexibility, but mistakes can happen in API design. Open source requires time management and feedback from users. API design is influenced by typing ease and good TypeScript support. Getting involved in open source involves trial and error and joining community platforms like TanStack Discord. Dominik's journey started during the pandemic and he can be found on Twitter, TanStack Discord, and his blog.

React Query - The Bad Parts
Top Content

React Query is a popular library with significant weekly downloads and positive user sentiment. It may have trade-offs like bundle size, but the actual size shipped is smaller. Bundle size optimization can be achieved by exporting only necessary features. React Query's declarative approach eliminates the need for custom data fetching solutions. It offers caching, request duplication, background updates, and more. RackQuery doesn't support normalized caching, but refetching after invalidation works fine. React's vision includes suspense architecture and server components. The documentation could be improved with a more structured flow. TensorStack Query can be a good choice for Next.js apps, but not necessary with mature frameworks. The 10 stack query and router concepts were discussed. Combining React Query with HTTP caching provides a robust caching solution.

Scaling Up with Remix and Micro Frontends
Top Content

This talk discusses the usage of Microfrontends in Remix and introduces the Tiny Frontend library. Kazoo, a used car buying platform, follows a domain-driven design approach and encountered issues with granular slicing. Tiny Frontend aims to solve the slicing problem and promotes type safety and compatibility of shared dependencies. The speaker demonstrates how Tiny Frontend works with server-side rendering and how Remix can consume and update components without redeploying the app. The talk also explores the usage of micro frontends and the future support for Webpack Module Federation in Remix.

Lessons From Adopting React Compiler

Akash Hamilwasia presenting at React Summit 2025, shares React Compiler learnings and works on an AI audio platform. Memoization in React helps optimize UI performance by preventing unnecessary re-renders. React Compiler offers automatic memoization through static code analysis. React rules emphasize purity and immutability. The compiler analyzes and memoizes code changes for optimization. React Compiler package usage improves performance through code analysis. Understanding reactivity issues is crucial for handling React state. Compiler optimization requires correct dependency arrays and usage of external libraries. Measure React Compiler impact using React Profiler for optimization and real user impact analysis.
