Valid IANA timezone list

Question

I'm working on an Nodejs system support multi timezone users. Currently, I'm using moment.tz.names() to get list of available timezone. But I found out that some timezone in list is deprecated by this link. I also found this database from IANA. So is there anyway to keep my timezone data up to date? I'm trying to find a way to work with IANA database. Thank you if there are any other approaches.

Moment.js is no longer maintained, so the problem is likely to get worse. — Robby Cornelissen, Mar 05 '21 at 10:03
I knew it, but my system is using moment to deal with timezone problems. We are moving to date-fns, I don't know if date-fns have a timezone list themselves? — Nguyen Hoang Vu, Mar 05 '21 at 10:04

I'd take a look at the tzdb package. It includes all IANA zones and is automatically updated on changes. You can get a list of timezones easily:

const { getTimeZones } = require("@vvo/tzdb");
const timeZones = getTimeZones();

console.log("Timezone (Berlin):", timeZones.find(tz => tz.name === "Europe/Berlin"));
console.log("Timezone (LA):", timeZones.find(tz => tz.name === "America/Los_Angeles"));
