Convert milliseconds to a human readable string:
1337000000→15d 11h 23m 20s
npm install pretty-ms
import prettyMilliseconds from 'pretty-ms';
prettyMilliseconds(1337000000);
//=> '15d 11h 23m 20s'
prettyMilliseconds(1337000000n);
//=> '15d 11h 23m 20s'
prettyMilliseconds(1337);
//=> '1.3s'
prettyMilliseconds(133);
//=> '133ms'
// `compact` option
prettyMilliseconds(1337, {compact: true});
//=> '1s'
// `verbose` option
prettyMilliseconds(1335669000, {verbose: true});
//=> '15 days 11 hours 1 minute 9 seconds'
// `colonNotation` option
prettyMilliseconds(95500, {colonNotation: true});
//=> '1:35.5'
// `formatSubMilliseconds` option
prettyMilliseconds(100.400080, {formatSubMilliseconds: true})
//=> '100ms 400µs 80ns'
// Can be useful for time durations
prettyMilliseconds(new Date(2014, 0, 1, 10, 40) - new Date(2014, 0, 1, 10, 5))
//=> '35m'
Type: number | bigint
Milliseconds to humanize.
Type: object
Type: number
Default: 1
Number of digits to appear after the seconds decimal point.
Type: number
Default: 0
Number of digits to appear after the milliseconds decimal point.
Useful in combination with process.hrtime().
Type: boolean
Default: false
Keep milliseconds on whole seconds: 13s → 13.0s.
Useful when you are showing a number of seconds spent on an operation and don't want the width of the output to change when hitting a whole number.
Type: boolean
Default: false
Only show the first unit: 1h 10m → 1h.
Also ensures that millisecondsDecimalDigits and secondsDecimalDigits are both set to 0.
Type: number
Default: Infinity
Number of units to show. Setting compact to true overrides this option.
Type: boolean
Default: false
Use full-length units: 5h 1m 45s → 5 hours 1 minute 45 seconds
Type: boolean
Default: false
Show milliseconds separately. This means they won't be included in the decimal part of the seconds.
Type: boolean
Default: false
Show microseconds and nanoseconds.
Type: boolean
Default: false
Display time using colon notation: 5h 1m 45s → 5:01:45. Always shows time in at least minutes: 1s → 0:01
Useful when you want to display time without the time units, similar to a digital watch.
Setting colonNotation to true overrides the following options to false:
compactformatSubMillisecondsseparateMillisecondsverboseType: boolean
Default: false
Hides the year and shows the hidden year additionally as days (365 per year): 1y 3d 5h 1m 45s → 368d 5h 1m 45s.
Type: boolean
Default: false
Hides the year and days and shows the hidden values additionally as hours: 1y 3d 5h 1m 45s → 8837h 1m 45s.
Type: boolean
Default: false
Hides the seconds: 1y 3d 5h 1m 45s → 1y 3d 5h 1m.
