A collection of small JavaScript helper classes and methods for implementing the idle-until-urgent performance pattern, built around requestIdleCallback(). It includes helpers like IdleQueue, IdleValue, defineIdleProperty, and polyfills for idle callback APIs.
Use cases
- reduce first input delay by deferring non-critical work
- polyfill requestIdleCallback in older browsers
- run initialization code during browser idle time
- defer expensive property computation until needed
- queue background tasks to avoid blocking the main thread
When to choose
- you need to reduce main-thread blocking and improve interaction latency
- you want a lightweight, per-helper importable utility for idle scheduling
- you must support legacy browsers like IE9+ with idle callback polyfills
When to avoid
- your runtime is not a browser environment
- you need a maintained, actively developed solution (last release 2023)
- you use a framework that already provides built-in idle-time scheduling
