Inactivity Listener

Do something when a timespan of no interaction passes.
Straightforward;
It sets a timeout that can be reset by internal eventListeners -
or through the public API.
When time passes your callback is executed.

Features

• No permission needed unlike in Chrome’s IdleDetector.
• EventListeners deal with common stopPropagation uses.
• After timeout, a next timeout with the same parameters can be set.
• Time passed since last activity available before and after timeout,
  until a (re)start.
• Event types causing a reset are configurable.
• Typescript

Install

Install the package as npm package. Provided are
a umd-formatted file in the dist folder to require or just read
and an es-module in the module folder to import.

Usage

Start watching activity, waiting for inactivity.
optional replace standard events to watch:

let interval = 120000 // 20 minutes
let callback = function () {
    if (window.alert('Ready to resume?')) {
        inactivityListener.restart()
    }
}
let events = ['touchstart', 'pointerdown']
inactivityListener.start(interval, callback[, events])

Reset timer when ticking:

inactivityListener.reset()

Report inactivity, in milliseconds:

let inactiveTime = inactivityListener.lapse

Resume listening after timeout:

inactivityListener.restart()

Remove listeners, clear timer:

inactivityListener.stop()
