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.
