Adding Morse code to any web application should be fun and easy. CW.js is a Javascript library that allows developers to embed Morse code widgets into their existing websites and applications.

Getting Started

First, add the CW.js script to your website by linking it to our CDN:

<script src="https://cwjs.mastercw.com/cw.min.js"></script>

Now, you can call the Morse code function anywhere in your code:

cw.play("Hello world");

The tone frequency and speed are customizable by passing an options object:

cw.play("Hello world", {
  tone: 700, // tone frequency in Hz
  wpm: 20, // speed in words per minute
  fwpm: 10, // farnsworth speed in words per minute
});

Library Usage

CW.js is also available for installation via NPM:

$ npm install cw

It can then be imported into any Node module:

const cw = require('cw');

Development and Building

Developers wishing to work on the library can clone the repository and run their own builds:

$ git clone https://github.com/mastercw/cw.js.git
$ npm install
$ npm run build
