react-app-menu

A simple desktop like menu bar with hotkey and keyboard navigation

BuildStatus Dependencies CodeCoverage Maintainability

Introduction

React App Menu is a simple React component that renders navigation menu similar to desktop applications with support for hotkeys and keyboard navigation. It aims to do most things through css alone and relies on javascript only when absolutely necessary. This makes the code extremely small (< 20kb) and together with the css, the whole library is less than 25 kb without any compression

Installation

npm install react-app-menu

Demo

react-app-menu-demo

Browser Support

This component relies on the css pseudo selector focus-within to open menus. This should work on Chrome and Firefox out of the box. For browsers that don't support the focus-within pseduo selector (notably IE and version of Edge prior to Edge 79), you will need to include a small polyfill focus-within-polyfill. The demo above is using Edge with the polyfill

To use the polyfill, you can either

  1. Include the following script tag <script src='https://unpkg.com/focus-within-polyfill/dist/focus-within-polyfill.js'></script>
  2. Install and import the focus-within-polyfill

This polyfill will only kick in for browsers that don't support the focus-within polyfill and adds a listener for blur and focus events and adds a .focus-within class as necessary.

Usage

Simply import MenuBar and Menu and start composing your menu. A css is also provided in dist/styles/react-app-menu.css. Be sure to import the css

Customizing the themes

In order to customize the look of the menu, certain css variables are provided that you can override on your menu
