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.

Installation

npm install locale-util

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, findTerritories, findCountryTerritory
} from 'locale-util'

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

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

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

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

isCurrencyCode('TRY') // true

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

findCountryCurrencyCode('TR') // TRY
findCountryCurrencyCode('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

findTerritories() /*
[
    {
        "code": "005",
        "name": "South America"
    },
    {
        "code": "011",
        "name": "Western Africa"
    },
    ...
    ...
]
*/

findCountryTerritory('TR') // { code: '145', name: 'Western Asia' }
findCountryTerritory('TR') // { code: '021', name: 'Northern America' }

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.

locale-util's Issues

Version 3.1.1 broken with CJS require()

Version 3.1.0 worked fine, but version 3.1.1 broke CJS require() imports. Sample script:

$ npm i [email protected]
$ node -e "const { findCountryTimezones } = require('locale-util')"
node:internal/modules/cjs/loader:553
      throw e;
      ^
