Worked on maintaining compatibility for the Vue Query plugin within the TanStack/query repository, focusing on front end development using Vue.js and TypeScript. Addressed a breaking change by replacing the deprecated isServer property with environmentManager.isServer(), ensuring the plugin continued to function with the latest library version. This update prevented potential disruptions for end users and reduced upgrade risks. Included a changeset to document and track the modification, supporting future maintainability. The work demonstrated attention to evolving dependencies and proactive risk mitigation, contributing to stable plugin behavior without introducing new features, and reflected a methodical approach to bug resolution and codebase upkeep.
