The Unicode Common Locale Data Repository it’s “the largest and most extensive repository of locale data available”, so it’s pretty much the perfect solution when you need information such as:
- Currency values, with ISO codes and visualization formats
- Dates and times patterns, including timezones
- List of “territories”, countries, continents, etc. with their corresponding languages, currencies
- Translations of all of the above
You can get their data from their Downloads page in XML format (follow the links in the Data column) or, if you prefer JSON, you may the Releases on their GitHub repository.
The JSON data it’s also available for use with NPM or bower.
