enum-values

Library for getting the names and values of typescript enum

Installation

npm install enum-values --save

Example in TypeScript

  import { EnumValues } from 'enum-values';

  // Suppose we have an numeric and a string valued enum
  enum NumericEnum {
    VALUE1,
    VALUE2,
    VALUE3
  }

  enum StringEnum {
    VALUE4 = 'V4',
    VALUE5 = 'V5'
  }

  // names will be equal to: ['VALUE1', 'VALUE2', 'VALUE3']
  var names1 = EnumValues.getNames(NumericEnum);

  // names will be equal to: ['VALUE4', 'VALUE5']
  var names2 = EnumValues.getNames(StringEnum);

  // values will be equal to: [0, 1, 2]
  var values1 = EnumValues.getValues(NumericEnum);

  // values will be equal to: ['V4', 'V5']
  var values2 = EnumValues.getValues(StringEnum);

  // name will be 'VALUE4'
  var nameFromValue1 = EnumValues.getNameFromValue(StringEnum, 'V4')

  // name will be null
  var nameFromValue2 = EnumValues.getNameFromValue(StringEnum, 'AB')

  // name will be 'VALUE1'
  var nameFromValue3 = EnumValues.getNameFromValue(NumericEnum, 0);
  
  // namesAndValues will be equal to:
  // [
  //  { name: 'VALUE1', value: 0 },
  //  { name: 'VALUE2', value: 1 },
  //  { name: 'VALUE3', value: 2 }
  // ]
  var namesAndValues1 = EnumValues.getNamesAndValues(NumericEnum);

  // namesAndValues will be equal to:
  // [
  //  { name: 'VALUE4', value: 'V4' },
  //  { name: 'VALUE5', value: 'V5' }
  // ]
  var namesAndValues2 = EnumValues.getNamesAndValues(StringEnum);
