const timezoneNames = new TimezoneNames({
    display: {
        de_DE: germanDisplay,
        en_US: englishDisplay
    },
    cldr: {
        de: germanCldr,

Developing & regenerating data

Place a data.json (unextracted, not the .gz) from the original repo linked in the intro into the dev directory and run node ./dev/update-data.js in the project folder to regenerate the .json files under data.

Notes

• if you want to load all locales at once, there's an example in the test file
• this should also work in the browser, but I haven't tested that
• if you want more features or have found bugs, feel free to contribute to this project
