re-intl
re-intl
helps you with date, number and currency formatting in ReasonML
(BuckleScript). Everything is built on top of Intl which comes built-in with
browsers >= IE11 as well as Node.
Get started
npm install re-intl
Add re-intl
in bsconfig.json
{
"dependencies": ["re-intl"]
}
Examples
DateTime
let today = Intl.DateTime.make(~locale=Some("sv-SE"), ());
// today: string = 2020-03-18 (based on current date)
with custom date
let date = Js.Date.makeWithYMD(~year=2020., ~month=11., ~date=12., ());
let futureDate = Intl.DateTime.make(~date, ~locale=Some("sv-SE"), ());
// futureDate: string = 2020-11-12
with date as string
let futureDate = Intl.DateTime.makeFromString(~date="2020-11-12", ~locale=Some("sv-SE"), ());
// futureDate: string = 2020-11-12
and with some options
let today =
Intl.DateTime.make(
~locale=Some("sv-SE"),
~options=
Options.make(
~year=Some(`numeric),
~weekday=Some(`long),
~day=Some(`twoDigit),
~era=Some(`narrow),
~month=Some(`long),
(),
),
(),
);
// today: onsdag 18 mars 2020 e.Kr. (based on current date)
NumberFormat
Currency
let krona =
Intl.NumberFormat.Currency.make(
~value=1000.,
~currency=Some("SEK"),
~locale=Some("sv-SE"),
(),
);
// krona: string = "1 000,00 kr"
Decimal
let parsedNumber =
Intl.NumberFormat.Decimal.make(~value=1000., ~locale=Some("sv-SE"), ());
// parsedNumber: string = "1 000,00"
Node
Node only has support for en-US
locale by default. If your code is failing
with wrong formatting you'll need to install full locale support using:
npm install -g full-icu
The installer will print out what you need to set the environment variable NODE_ICU_DATA
to in order to get full support.
