A library that tracks browser keyboard focus state that powers tabster

by React

Keyborg ⌨️?

Keyborg is a library that tracks the state of current keyboard input on a web page through focus events.

It does not do anything invasive to the DOM but provides an event subscription system that allows users to choose how they want to react to changes in focus.

Getting started

Installation

# NPM
npm install --save keyborg
# Yarn
yarn add keyborg

Usage

import { createKeyborg } from "keyborg";

// initializes keyborg on the current window
const keyborg = createKeyborg(window);

// This is called every time the keyboard input state changes
const handler = (isUsingKeyboard) => {
  if (isUsingKeyboard) {
    document.body.setAttribute("data-is-keyboard", "true");
  } else {
    document.body.removeAttribute("data-is-keyboard");
  }
};

keyborg.subscribe(handler);
keyborg.unsubscribe(handler);
