A TypeScript library for inactivity timer, which utilises IdleDetector API where possible or a fallback to window.setTimeout approach.
npm install idle-detectimport IdleDetect from 'idle-detect'
// Or, if you don't want to use still experimental IdleDetector API:
// import { IdleDetect } from 'idle-detect/dist/IdleDetect'
const onInactive = () => {
console.info('User is inactive now')
}
const idleDetect = new IdleDetect(15 * 60, onInactive)
// Start timer, e.g. when user is logged in
idleDetect.start()
// End timer, e.g. when user is logged out
idleDetect.cleanupAndStop()
