tanstack-pacer

TanStack Pacer is a lightweight, type-safe library for controlling function execution timing through debouncing, throttling, rate limiting, queuing, and batching. It provides framework-agnostic core classes with dedicated React hooks at multiple abstraction levels (instance, callback, state, value).

When to use: Debouncing search input, throttling scroll/resize handlers, enforcing API rate limits, queuing async tasks with concurrency control, batching multiple operations into single requests.

When NOT to use: Simple one-off delays (use setTimeout), server-side rate limiting at the infrastructure level (use middleware/API gateway), complex job scheduling (use a task queue like BullMQ).

TanStack Pacer 用於速率限制、節流、去抖動和非同步佇列。在控制執行頻率、管理 API 速率限制、消除使用者輸入或對非同步任務進行排隊時使用。用於心律調節器、節流閥、去抖動、速率限制、隊列、非同步節流閥、速率限制。 來源：oakoss/agent-skills。
