[SOLVED] moment.duration.format to show 12 sec in the format 00:12 (mm:ss)

[fntgnn]

Hi. How can I use the format to show for example 12 seconds in the format 00:12 and not only 12? I used format('mm:ss', { forceLength: true } but it does not work.

Thank you. Giovanni.

In your case you'd want this:

moment.duration(12, "seconds").format('mm:ss', { trim: false });
// "00:12"

forceLength acts on individual tokens that aren't trimmed, when the leading token in the format string has a length of 1. Sounds more complicated that it is...

No. Is not working as expected

import moment from 'moment'
import momentDurationPlugin from 'moment-duration-format'
momentDurationPlugin(moment)

moment.duration(12, "seconds").format('mm:ss', { trim: false })
// 0:12
moment.duration(12, "seconds").format('mm:ss', { trim: false })
// 0:1
moment.duration(1200, "seconds").format('hh:mm', { trim: false })
// 0:20

"moment": "2.19.4",
"moment-duration-format": "2.1.0",

@mikeevstropov what environment are you using?

A quick check in Chrome and I see:

moment.duration(12, "seconds").format('mm:ss', { trim: false })
// "00:12"
moment.duration(12, "seconds").format('mm:ss', { trim: false })
// "00:12"
moment.duration(1200, "seconds").format('hh:mm', { trim: false })
// "00:20"

The output padding in version 2 comes from toLocaleString... are you in an environment with a borked version of toLocaleString?

@jsmreese Hi! Thank you for fast reply =)

That explains it. As I'm learning, there are lots of environments where you can use moment that don't provide a fully baked toLocaleString.

I'll see what I can do about getting a fallback implementation of toLocaleString into the plugin.
