How to correctly format a postgres timestamp with timezone date using date-fns?

Question

I'm moving from moment to date-fns and need some advice.

I have a postgres timestamp-with-timezone and I'm looking to format it like MAR 2 AT 1:30 PM .

Here is my solution using date-fns .

import { format, parseISO } from 'date-fns';

const date = parseISO(message.updated_at); // this is from postgres
const md = format(date, 'MMM d').toUpperCase();
const hm = format(date, 'h:m a');
const formattedTimestamep = `${md} AT ${hm}`;

Is there a more correct or less verbose way?

Answer 1

_{I got an answer over in the date-fns github issues .}

There's a small useful sentence in the docs for format .

The characters wrapped between two single quotes characters (') are escaped.

This leads to this more succinct version of the code.

const formattedTimeStamp = format(parseISO(message.updated_at), "MMM d 'AT' h:m a").toUpperCase();
