Millit

This utility allow convert strings to milliseconds. You can use even compost times.

Examples

millit('10 days') // 864000000
millit('10d') // 864000000
millit('5h') // 18000000
millit('12 hrs') // 43200000
millit('2.5hours') // 9000000
millit('1min 10s') // 70000
millit('10d 5seconds') // 864005000
millit('1year 45days') // 35445600000
millit("45days 1year") // 35445600000 - sames as before, order doesn't matter
millit('100h 12m') // 360720000
millit('1 days') // 86400000
millit('20') // 20
millit('-200h') // -720000000

Installation

Install it with you favorite package manager:

npm install millit
OR
yarn add millit

Usage:

If you are using plain javascript:

const millit = require("millit")

millit("10d")

if you are using typescript:

import millit from "millit"

millit("10d")

Features

The fact that the order doesn't matter empowers you to dynammically sum up different dates whitout be afraid of date inconsistencies. Example:

let myDateStr = "10d"
let sum10m = true

if(sum10m) {
  myDateStr += "10m"
  console.log(millit(myDateStr)) //864600000
} else {
  myDateStr += "1y"
  console.log(millit(myDateStr)) // 32421600000
}

hint: Try to change sum10m to false

disclaimer: When dynammically summing milliseconds along with other time units as above, always include the "ms" prefix. For example, "10d 10ms 20m" works as expected, while omitting the "ms" prefix in expressions like "10d 10 20m" will result in a silent error (NaN).

How it compares with MS

const tenDays = ms("10d")
const tenSecs = ms("10s")
const withMs = tenDays + tenSecs

const withMillit = millit("10d 10s")
console.log(withMs === withMillit) // true

console.log(ms(withMs)) // 10d
console.log(millit(withMillit)) // 10d

hint: This package is written intended to be fully compatible with the results that ms would give.

Performance

This package is just a convenience for small projects. It is not intended to be a substitute for "ms" as this package uses simple for loops to search through strings. It's not as powerful as "ms" which uses regex search, known to be faster for larger inputs.
