.
npm install cldr-compact-number --save
The following APIs take the language code as the the second argument based on ISO 639-1. You can also pass en_GB
and we will normalize it to en-GB
as well.
We default this library with en
localeData
. What is localeData
?
localeData
for most cases comes through a build tool. You define what languages you want upfront so as to avoid bloating your application bundle and the build tool parses CLDR data and formats it. See priv/
for examples of what shape the data should be in if you want to manually construct this data.
import compactFormat from 'cldr-compact-number';
compactFormat(19634, 'en', localeData);
// 19K
compactFormat(19634, 'en', localeData, {
significantDigits: 1,
minimumFractionDigits: 1,
maximumFractionDigits: 2
});
// 19.6K
compactFormat(101, 'en', localeData, {
significantDigits: 1,
financialFormat: true
});
// 0.1M
compactFormat(19634, 'ja', localeData);
// 2万
compactFormat(19634, 'es', localeData, { significantDigits: 1 });
// 19,6 mil

."Wait, I thought this addon was for compact number formatting?" Well it can be a misnomer depending on the language. Let's look at some examples.
This doesn't seem shorter!!!! (╯°□°)╯︵ ┻━┻
compactFormat(101000, 'en', localeData, { long: true });
// 101 thousand
But this does! ʘ‿ʘ
compactFormat(101000, 'ja', localeData, { long: true });
// 101万
So we will just go with cldr-compact-number
for now.
Currently this only shortens with latin digits 0..9
