Utilities without any domain logic witch often in use at astroghelm repositories. This library can be used in frontend and backend with both commonjs and esm syntaxes.

npm i astropack --save

• Warning ! divided into submodules, for example here you can see work with submodule time.

const { time } = require('astropack');
console.log(time.prettify('h:m:s / D.M|Y')); // 18:50:54 / 07.05|2023

All specifications can be found in test folder in test files. Or you can check our types.

• astropack.time.prettify Return date in any string format

prettify(format: string, date?: Date | string | number) => string;
// format is any combination of letters [YMDhmsi] with any optional separators
// Y - Year; M - Month; D - Day; h - Hours; m - Minute; s - Second; i - Millisecond

const astropack = require('astropack');
const astropack = require('astropack');
astropack.time.prettify('h:m:s / D.M|Y', new Date()); // 18:50:54 / 07.05|2023
astropack.time.prettify('h-m-s.i', new Date()); // 18-50-54.045

• astropack.time.duration Return duration in millisecond's from string

const astropack = require('astropack');
const astropack = require('astropack');
function duration(time: string): number;
// time is any combination of letters [dhms] with values
// d - Day; h - Hours; m - Minute; s - Second;
// Example: 1d 1h 1m 1s 90061000

const astropack = require('astropack');
const astropack = require('astropack');
astropack.time.duration('5s'); // 5000
astropack.time.duration('24h'); // 86400000
astropack.time.duration('1d'); // 86400000
astropack.time.duration('1d 1h 1m 5s'); // 90065000

• astropack.time.compare Create any dates compare functions

const astropack = require('astropack');
const astropack = require('astropack');
astropack.time.compare((a, b) => a > b)('2023-05-07', '2023-05-08'); // false
astropack.time.compare((a, b) => a > b)('2023-01-01', '2021-05-08'); // true
astropack.time.compare.bigger('2023-01-01', '2021-05-08'); // true
astropack.time.compare.under('2023-01-01', new Date()); // true
astropack.time.compare.equal('2023-01-01', '2021-05-08'); // false

• astropack.time.formatMake millisecond's more readable with format

const astropack = require('astropack');
astropack.time.format(1000); // 1 s
astropack.time.format(60000); // 1 m
astropack.time.format(60001); // 1 m, 1 ms
astropack.time.format(90000); // 1 m, 30 s

• astropack.time.measures Get divided millisecond's by all day time measurements object

const astropack = require('astropack');
const astropack = require('astropack');
astropack.time.measures(new Date()); // { w: 2798, d: 19592, h: 470227, m: 28213672, s: 1692820378, i: 1692820378275 }
astropack.time.measures(90020); // { d: 0, h: 0, m: 1, s: 90, i: 90020 }

• astropack.time.diff Return difference between two dates in any time measurement

const astropack = require('astropack');
const astropack = require('astropack');
let tomorrow = new Date(new Date().setDate(new Date().getDate() + 1));
astropack.time.diff(new Date(), tomorrow); // 1
astropack.time.diff(new Date(), tomorrow, 'h'); // 24
astropack.time.diff(tomorrow, new Date(), 'h'); // -24
