Worked on enhancing data integrity and stability within the TanStack/db repository by addressing a critical issue related to garbage collection in dynamic React applications. Focused on preventing data loss when React subscribers unmount, the solution involved disabling garbage collection for child collections created by the includes system. This adjustment ensured that data persisted beyond the default garbage collection window, supporting more robust includes-based queries and dynamic UI scenarios such as virtualized tables. The work included implementing a regression test to validate data retention and refining garbage collection lifecycle management, utilizing JavaScript, TypeScript, and state management techniques to strengthen reliability and testing coverage.
