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 用于速率限制、节流、去抖动和异步队列。在控制执行频率、管理 API 速率限制、消除用户输入或对异步任务进行排队时使用。用于起搏器、节流阀、去抖动、速率限制、队列、异步节流阀、速率限制。 来源：oakoss/agent-skills。
