Oct 1, 2025

Month 2025-10: Focused on strengthening linting reliability for TanStack Query integration and expanding test coverage. Delivered enhancements to the ESLint plugin to robustly detect illegal return types (void/undefined) in query functions and to improve detection of TanStack Query imports, with tests validating imports from non-TanStack sources. Refactored rule creation for better reliability.

Jul 1, 2025

Monthly summary for 2025-07 focusing on delivering key features and engineering value for vitejs/vite-plugin-react. The main achievement this month was enabling Hot Module Replacement (HMR) for compound components in the Vite React plugin, supported by new utilities to identify and register compound components and validated via a playground Accordion showcasing/test HMR behavior. No major bugs fixed this period. The changes reduce feedback loops for plugin users and improve development DX by delivering reliable, fast updates in the browser without full reloads.

Apr 1, 2025

Concise monthly summary for 2025-04 focusing on TanStack/query ESLint plugin improvements, build stability, and tooling enhancements. Delivered a new ESLint rule to enforce cacheable query functions, fixed build/compat issues for the ESLint plugin to support classic CommonJS export and older toolchains, and overhauled the build/test tooling with a separation of legacy/modern DTS and improved test coverage. These changes reduce runtime errors related to non-cacheable results, broaden compatibility across toolchains, and improve developer experience and CI reliability.

Nov 1, 2024

In November 2024, delivered targeted fixes and tooling improvements across chakra-ui/chakra-ui and TanStack/query, focusing on cross-browser UI reliability and developer tooling quality. Key outcomes include a Safari checkmark SVG visibility fix for Chakra UI (with an accompanying changeset) and a refined React Query ESLint Plugin that correctly accounts for external dependencies inside queryFn for exhaustive-deps, supported by new tests and utility refinements. These efforts reduce runtime UI issues and improve linting accuracy, contributing to more robust UI components and safer code patterns.
