Installing

Read the followings subtitles.

Package manager

Using npm:


$ npm install morse-key-converter

Using bower:


$ bower install morse-key-converter

Using yarn:


$ yarn add morse-key-converter

Using pnpm:


$ pnpm add morse-key-converter

Once the package is installed, you can import the library using the CommonJS require approach:


const MorseConverter = require('morse-key-converter');

For cases where something went wrong when trying to import a module into a custom or legacy environment,

you can try importing the module package directly:


const MorseConverter = require('morse-key-converter/src/index');

Run test file

once the package is installed, if you want to test the package's default test file, enter the following command:

$ cd node_modules/morse-key-converter
$ npm run start test

and if all is well you will observe the following :

$ npm run start-test

> node test.js

Example

Note CommonJS usage

The first step would be to import the MorseConverter class and instantiate it as shown below:


const MorseConverter = require('morse-key-converter');

// MorseConverter is a nodejs class so the first thing to do is to instantiate it using new as in the following example:

const morseConverter = new MorseConverter()

Available methods

Second step, use available methods.

The following methods are available : encodeText(inputString) //returns the string entered as a parameter encoded in Morse code. decodeMorseText(inputString) //returns the string entered as a parameter decoded into its corresponding Latin alphabet meaning.

Example of invocation :

//using the above variable containing the instantiated class
let textEncoded = morseConverter.encodeText('Hello world'); // output .... . .-.. .-.. --- / .-- --- .-. .-.. -..
let textEncoded = morseConverter.decodeMorseText('.... . .-.. .-.. --- / .-- --- .-. .-.. -..');// output HELLO WORLD

Encode example

The following is an example of converting some text to morse code:


const MorseConverter = require('morse-key-converter');
const morseConverter = new MorseConverter()

let textEncoded = morseConverter.encodeText('ABCDEFGHIJKLMNÑOPQRSTUVWXYZ');
console.log(textEncoded)

//output => .- -... -.-. -.. . ..-. --. .... .. .--- -.- .-.. -- -. --.-- --- .--. --.- .-. ... - ..- ...- .-- -..- -.-- --..

Decode example

The following is an example of converting some Morse code text into natural language:


const MorseConverter = require('morse-key-converter');
const morseConverter = new MorseConverter()

let textEncoded = morseConverter.decodeMorseText('.- -... -.-. -.. . ..-. --. .... .. .--- -.- .-.. -- -. --.-- --- .--. --.- .-. ... - ..- ...- .-- -..- -.-- --..');
console.log(textEncoded)

//output => ABCDEFGHIJKLMNÑOPQRSTUVWXYZ

And that's how our package works.

Resources

the alphabet used for the conversion is as follows:

const latin = {
  "A": ".-",
  "B": "-...",
  "C": "-.-.",
  "D": "-..",
  "E": ".",
  "F": "..-.",
  "G": "--.",
  "H": "....",
  "I": "..",
  "J": ".---",
  "K": "-.-",
  "L": ".-..",
  "M": "--",
  "N": "-.",
  "Ñ": "--.--",
  "O": "---",
  "P": ".--.",
  "Q": "--.-",
  "R": ".-.",
  "S": "...",
  "T": "-",
  "U": "..-",
  "V": "...-",
  "W": ".--",
  "X": "-..-",
  "Y": "-.--",
  "Z": "--..",
  "1": ".----",
  "2": "..---",
  "3": "...--",
  "4": "....-",
  "5": ".....",
  "6": "-....",
  "7": "--...",
  "8": "---..",
  "9": "----.",
  "0": "-----",
  ".": ".-.-.-",
  ",": "--..--",
  "?": "..--..",
  "'": ".----.",
  "!": "-.-.--",
  "/": "-..-.",
  "(": "-.--.",
  ")": "-.--.-",
  "&": ".-...",
  ":": "---...",
  ";": "-.-.-.",
  "=": "-...-",
  "+": ".-.-.",
  "-": "-....-",
  "_": "..--.-",
  "\"": ".-..-.",
  "$": "...-..-",
  "@": ".--.-.",
  "¿": "..-.-",
  "¡": "--...-",
  " ": "/"
}

const latinExtended = {
  'Ã': '.--.-',
  'Á': '.--.-',
  'Å': '.--.-',
  'À': '.--.-',
  'Â': '.--.-',
  'Ä': '.-.-',
  'Ą': '.-.-',
  'Æ': '.-.-',
  'Ç': '-.-..',
  'Ć': '-.-..',
  'Ĉ': '-.-..',
  'Č': '-.-..',
  'Ę': '..-..',
  'Ð': '..--.',
  'È': '.-..-',
  'Ë': '..-..',
  'É': '..-..',
  'Ê': '..-..',
  'Ğ': '--.-.',
  'Ĝ': '--.-.',
  'Ĥ': '----',
  'İ': '.-..-',
  'Ï': '-..--',
  'Ì': '.---.',
  'Ĵ': '.---.',
  'Ł': '.-..-',
  'Ń': '--.--',
  'Ñ': '--.--',
  'Ó': '---.',
  'Ò': '---.',
  'Ö': '---.',
  'Ô': '---.',
  'Ø': '---.',
  'Ś': '...-...',
  'Ş': '.--..',
  'Ș': '----',
  'Š': '----',
  'Ŝ': '...-.',
  'ß': '...',
  'Þ': '.--..',
  'Ü': '..--',
  'Ý': '..--',
  'Ù': '..--',
  'Ŭ': '..--',
  'Ž': '--..-',
  'Ź': '--..-.',
  'Ż': '--..-'
}

Because the extended Latin can be handled in different ways the following JSON was used to decode this can be easily updated: Reference link : https://ham.stackexchange.com/questions/1379/international-characters-in-morse-code

const toDecodeLatinExtended = {
  '.--.-': 'Ã',
  '.-.-': 'Ä',
  '-.-..': 'Ç',
  '..-..': 'Ę',
  '..--.': 'Ð',
  '.-..-': 'È',
  "--.-.": "Ğ",
  "----": "Ĥ",
  "-..--": "Ï",
  ".---.": "Ì",
  "---.": "Ó",
  "...-.": "Ŝ",
  ".--..": "Ş",
  "..--": "Ü",
  "--..-": "Ž",
  "--..-.": "Ź",
}
