#How to use

These formatters are best used in conjunction with @onigoetz/messageformat. However they are fully Typed and you may use them for any other use.

import { parse, createRenderer } from "@onigoetz/messageformat";
import {
  dateFormatter,
  numberFormatter,
  pluralGenerator,
} from "@onigoetz/intl-formatters";

// Parse the MessageFormat to a renderable format
const parsed = parse("{test, plural, offset:3 one{one test} other {# test} }");

// Create a localized renderer
const render = createRenderer(
  "en",
  (locale: T, type) => pluralGenerator(locale, { type }),
  (locale: T, options, value: number) =>
    numberFormatter(locale, options)(value),
  (locale: T, options, value: Date) => dateFormatter(locale, options)(value)
);

render(parsed, { test: 4 }); // => "one test"
render(parsed, { test: 7 }); // => "4 test"

#For NodeJS

If you do some generation using NodeJS and wish to use locales other than en. I strongly suggest you look at the following page : https://nodejs.org/api/intl.html#intl_providing_icu_data_at_runtime This page explains how to make sure you have all the right locales loaded to make your formatting.
