convert a human readable duration to ms
npm install parse-duration
then in your app:
var parse = require('parse-duration')
convert str
to ms
var ns = parse('1ns') // => 1 / 1e6
var μs = parse('1μs') // => 1 / 1000
var ms = parse('1ms') // => 1
var s = parse('1s') // => ms * 1000
var m = parse('1m') // => s * 60
var h = parse('1h') // => m * 60
var d = parse('1d') // => h * 24
var w = parse('1w') // => d * 7
var y = parse('1y') // => d * 365.25
It can also handle basic compound expressions
parse('1hr 20mins') // => 1 * h + 20 * m
whitespace
parse('1 hr 20 mins') // => 1 * h + 20 * m
comma seperated numbers
parse('27,681 ns') // => 27681 * ns
And most other types of noise
parse('running length: 1hour:20mins') // => 1* h + 20 * m
You can even use negatives
parse('2hr -40mins') // => 1 * h + 20 * m
And exponents
parse('2e3s') // => 2000 * s
Available unit types are:
- nanoseconds (ns)
- microseconds (μs)
- milliseconds (ms)
- seconds (s, sec)
- minutes (m, min)
- hours (h, hr)
- days (d)
- weeks (w, wk)
- months
- years (y, yr)
And its easy to add more
