# `leader-tab`

An algorithm for selecting a leader from all the open tabs of a website. Uses the [Broadcast Channel](https://developer.mozilla.org/en-US/docs/Web/API/Broadcast_Channel_API) API for synchronization.

```typescript

import { elector } from "leader-tab";

const tab = elector({

  onLeaderElected: () => {

    console.log("I am the leader");

  },

  onLeaderDemoted: () => {

    console.log("I got demoted");

  },

});

console.log("Current tab id", tab.getTabId());

console.log("Is current tab the leader", tab.isLeader());

console.log("Stop all synchronization work", tab.destroy());

```
