如何使用 Luxon 从 UTC 日期获取相对时间？

Question

I store my creation dates for posts as DateTime.UtcNow() with my .net core api.

If I use Moment.js it is as simple as :

convertedDate(date: Date) {
    return moment.utc(date).fromNow();
}

This returns something like 22 hours ago or 19 minutes ago.

I was unable to really find information on how to work with the luxon library.

Any tips?

Answer 1

It looks like Luxon doesn't support this behavior because it doesn't have access to internationalized strings. More information/alternatives can be found here.

Answer 2

First include library or install, say like

<script src="https://cdn.jsdelivr.net/npm/luxon@1.10.0/build/global/luxon.js"></script>

Then use following format to get proper output:

const DateTime = luxon.DateTime;
console.log(DateTime.local().plus({ days: 1 }).toRelative()); // in 23 hours
console.log(DateTime.local().minus({ days: 2 }).toRelative({ unit: "hours" })); //48 hours ago
console.log(DateTime.local().toObject()); // year: 2020 month: 2 day: 25 hour: 0 minute: 4 second: 20 millisecond: 764
console.log(DateTime.local(2014, 7, 13).toSQL({ includeZone: true })); // 2014-07-13 00:00:00.000 Asia/Dhaka

Besides, If you want to explore more to learn other methods please read documentation for Luxon.

You can use toRelative() luxon function, it works same way. For example:

DateTime.local().minus({ days: 2 }).toRelative() //=> "2 days ago"
