enum in javascript

npm i js-enums

simple to use

const enum = require('js-enums');

var status = enum([
  {
    name: 'CLOSED',
    ortherInfo: 'status close'
  },
  {
    name: 'OPENED',
    ortherInfo: 'status open'
  }
]);
 
// or declare in this way: 
// var status = enum(['OPENED', 'CLOSED']);


status.OPENED; // { name: 'OPENED', order: 0, ortherInfo: 'status open' }

status.getByOrder(1); // { name: 'OPENED', order: 0, ortherInfo: 'status open'}

status.OPENED.eql('OPENED') // true

only two APIs

• eql

compare with enum

• getByOrder

return the enum by order

some tips

• init order

order only can init in first position of the array, and order is increased by step 1.

var status = enum([
  {
    name: 'CLOSED',
    order: 2
  },
  {
    name: 'OPENED',
  }
]);


status.OPENED.order; // 3

• custom eql

var status = enum(['OPENED', 'CLOSED']);

status.OPENED.eql('OPENED') // true, eql by name, param must be string

status.OPENED.eql(0) // true, eql by order, param should not be NaN

status.OPENED.eql({name: 'OPENED'}) // true

status.OPENED.eql({name: 'OPENED', order: 2}) // false

status.OPENED.eql({name: 'OPENED', order: 1, ortherInfo: 'status open'}) // true
