TanStack Pacer provides lightweight timing utilities (debouncing, throttling, batching, rate limiting) for React applications without the complexity of RxJS. The guide demonstrates building a Pinterest-style infinite scroll image gallery using Pacer's core features: debounced search input to reduce API calls, throttled scroll handlers for performance, batched analytics events to minimize network requests, and rate-limited API calls to enforce usage constraints. Each utility is implemented with React hooks and includes practical testing approaches to verify behavior.
