Kwan worked on TanStack/query, focusing on stabilizing test suites, improving code quality, and delivering new features for React Query. Over five months, Kwan expanded test coverage for core behaviors, introduced deterministic testing with fake timers, and enforced TypeScript type safety to reduce regressions. They implemented a Static Query Indicator in Query DevTools using React, TypeScript, and CSS, enhancing UI feedback for developers. Kwan also addressed dynamic query composition bugs, ensuring correct cache invalidation and stable references. Their work emphasized asynchronous programming, ESLint configuration, and unit testing, resulting in more reliable releases and maintainable code across the TanStack/query repository.

Jan 1, 2026January 2026 monthly summary focused on stabilizing dynamic query composition in TanStack/query. Delivered a critical bug fix for Dynamic Query Combine Update with dynamic queries, expanded test coverage to validate stable references and correctness of combined results, and prepared release artifacts via changesets. This work improves reliability of complex query compositions and reduces stale data in dynamic query scenarios.

Jun 1, 2025June 2025 monthly summary for TanStack/query focusing on feature delivery and code quality improvements. Key features delivered include a Static Query Indicator in Query DevTools to visually signal when a query's staleTime is set to 'static', along with the detection logic and CSS styling. Additionally, enforcement of code quality and async handling via a typescript-eslint rule (require-await) reduced unnecessary async usage in tests and codemods, improving consistency and maintainability. These changes enhance developer experience, reduce debugging time, and contribute to more predictable asynchronous behavior.

May 1, 2025Month: 2025-05 — TanStack/query focused on strengthening test coverage for the query-core subsystem, delivering a comprehensive test suite that validates core behaviors and guardrails against regressions. The primary feature delivered was Query Core Test Coverage Improvements, adding extensive tests across useSuspenseQuery with refetchInterval, InfiniteQueryBehavior, optimistic updates, and queryObserver options (refetchOnWindowFocus, fetchOptimistic, error tracking, fetchStatus), plus coverage for persisters and invalid query keys. A refactor to hashQueryKeyByOptions was included to improve reliability and hash-based caching. The work is supported by focused test commits (test(react-query): add test case for useSuspenseQuery (#8731); test(query-core): add test case for infiniteQueryBehavior (#9101); test(query-core): add test case for InfiniteQueryObserver (#9141); test(query-core): add test case for queryObserver (#9146); test(query-core): add test case for query (#9145)).

Apr 1, 2025April 2025: Stabilized test suites, improved code quality, and tidied API surface across TanStack/query. Key work included ESLint require-await fixes across core modules, the introduction of fake timers to stabilize timing-sensitive tests, expansion of query-core test coverage, and targeted test cleanup and API surface refinements. These changes reduce CI flakiness, improve maintainability, and support faster, safer development cycles.
