locale-util

Unicode CLDR data parser and module, regularly updated based on https://github.com/unicode-org/cldr releases. Refer to https://muratgozel.github.io/locale-util/ for full api docs.

⭐ Breaking Changes in v3

In v3, I extended the scope of the package, made it a module that has the necessary methods to interact with the data.

Installation

npm install locale-util
Copy

Usage

The package contains large amount of data which is not suitable for browser environment. Benefit from tree-shaking might work if you are interested in small chunks of it.

Here are the methods that you can use to interact with the data:

import {isCountryCode, findCountry, findCallingCode, findCountryLanguages, 
    isCurrencyCode, findCurrency, isLanguageCode, findLanguage, 
    findCountryTimezones, findTimezoneOffset} from 'locale-util'

isCountryCode('TR') // true
isCountryCode('XX') // false

findCountry('TR') /*
{
    'code': 'TR',
    'englishName': 'Turkey',
    'nativeName': 'Türkiye'
}
*/
findCountry('ABC') // undefined

findCallingCode('US') // 1
findCallingCode('TR') // 90
findCallingCode(null) // undefined

findCountryLanguages('TR') // ['tr']
findCountryLanguages('US') // ['en', 'es', 'haw']

isCurrencyCode('TRY') // true

findCurrency('TRY') /*
{
    'code': 'TRY',
    'num': 949,
    'englishName': 'Turkish',
    'nativeName': 'Türkçe'
}
*/

findCurrencyCode('TR') // TRY
findCurrencyCode('US') // USD

isLanguageCode('xxx') // false
isLanguageCode('tr') // true

findLanguage('tr') /*
{
    'code': 'tr',
    'nativeName': 'Türkçe',
    'englishName': 'Turkish'
}
*/

findCountryTimezones('TR') /*
[{
    'name': 'Europe/Istanbul',
    'offset': -180,
    'country': 'TR'
}]
*/

findCountryTimezones('TT') /*
[{
    'name': 'America/Port_of_Spain',
    'offset': 240,
    'country': 'TT'
}, {
    'name': 'America/Puerto_Rico',
    'offset': 240,
    'country': 'TT'
}]
*/

findTimezoneOffset('America/Puerto_Rico') // 240
findTimezoneOffset('Europe/Istanbul') // -180
Copy

Have a look at the tests, types and source for more info.

Keeping Data Up To Date

Data updates published regularly as minor releases so you only need to update the package as new version comes in. If you have a kind of manual setup, download the release you wish from https://github.com/unicode-org/cldr/releases and copy the common directory under cldr-data-common. Then run npm run setup, compile, build and test to parse the new data.
