@tuplo/numberfmt v1.11.0

Why

JS provides powerful number formatting with the standard built-in object Intl.NumberFormat, but we find its API a little verbose and hard to grasp its full potential. We took inspiration from older libraries like numbro.js and numeral.js and built a string based pattern for interacting with Intl.NumberFormat. Tiny footprint, no dependencies, works on the browser or nodejs.

Usage

import nf from '@tuplo/numberfmt';

// numeric
nf(123_456, '0,0.00'); // → 123,456.00

// currency
nf(123_456, '0,0GBP'); // → £123,456

// digital units
nf(123_456, '0b'); // → 120.56kb

// with locale
nf(123_456, '0,0.00', { locale: 'ar-EG' }); // → ١٢٣٬٤٥٦٫٧٩

// functional programming, partial application
const nfp = nf.partial('0,0.00');
nfp(123_456); // → 123,456.00
