javascript - Format relative time in momentJs

Question

If I use

moment().startOf("minute").fromNow();

I will get:

a few seconds ago
a minute ago
...

Is it possible to format the output like the following?

00:00 minutes ago
00:01 minutes ago
...

Answer 1

You can customize how moment formats relative time for you locale using updateLocale.

Note that the docs says:

If a locale requires additional processing for a token, it can set the token as a function with the following signature. The function should return a string.

function (number, withoutSuffix, key, isFuture) {
    return string;
}

In your case, you can do something like this:

var m1 = moment().subtract(5, 'm');
var m2 = moment().subtract(15, 's');

console.log(m1.fromNow());
console.log(m2.fromNow());

moment.updateLocale('en', {
    relativeTime : {
        future: "in %s",
        past:   "%s ago",
        s: function (number, withoutSuffix, key, isFuture){
            return '00:' + (number<10 ? '0':'') + number + ' minutes';
        },
        m:  "01:00 minutes",
        mm: function (number, withoutSuffix, key, isFuture){
            return (number<10 ? '0':'') + number + ':00' + ' minutes';
        },
        h:  "an hour",
        hh: "%d hours",
        d:  "a day",
        dd: "%d days",
        M:  "a month",
        MM: "%d months",
        y:  "a year",
        yy: "%d years"
    }
});


console.log(m1.fromNow());
console.log(m2.fromNow());
