Shared Timers

[!WARNING] Mostly does not work on mobile https://caniuse.com/sharedworkers

Timers in SharedWorker, shared across browser tabs (within same origin). One timer per delay, many callbacks for each timer.

Motivation

• Keep timer callbacks in sync betweet tabs.
• Escape the throttling of window timers in inactive tabs.

Getting Started

Install using your preferred package manager, for example NPM:

npm install shared-timers

Use it in your project like this:

import { runTimer, clearTimer } from 'shared-timers'

const firstCallbackId = runTimer(() => {
    // Something executed periodically from a newly created `setInterval`.
}, 1000)

const secondCallbackId = runTimer(() => {
    // Something executed periodically from the same `setInterval`.
}, 1000)

// Remove callback from timer/execution.
clearTimer(secondCallbackId)
