easy-enum-js

A javascript enumeration class for nodejs.

Usage

The module exports a class Enum. Instantiation is easy:

let Enum = require('easy-enum-js');

const SampleEnum = new Enum('red', 'green', 'blue');

Values can be accessed by standard dot notation.

console.log(SampleEnum.green);

// output: 1

Or by the included function getVal(key).

A number of functions are included:

toString()

const SampleEnum = new Enum('red', 'green', 'blue');

SampleEnum.toString();

// output: "{ "blue": 0; "green": 1; "red": 2 }"

toObject()

const SampleEnum = new Enum('red', 'green', 'blue');

SampleEnum.toObject();

// output: { "blue": 0, "green": 1, "red": 2 }

getVal(key)

const SampleEnum = new Enum('red', 'green', 'blue');

SampleEnum.getVal('red');

// output: 2
