Worked on the sanity-io/visual-editing repository to enhance live editing by implementing caching for synchronization tag fetches, addressing data staleness and latency issues. Leveraged TypeScript and Next.js to introduce a new loader tag, 'sanity:fetch-sync-tags', and integrated server actions to ensure efficient revalidation and improved data synchronization. This approach increased editor responsiveness and system scalability by reducing redundant network requests and ensuring up-to-date content during live editing sessions. Additionally, resolved a critical issue affecting live sync tag fetches, further improving reliability. The work demonstrated a strong focus on caching strategies, server-side logic, and modern TypeScript development practices.
