Install

npm install --save numerous

Usage

Node.js

In Node.js environment the library automatically loads the required locales on first use.
const numerous = require('numerous');

// Create an instance of Numerous using preferred locale
const { pluralize } = numerous.create('en');

// Specify the list of variants
const variants = {
  one: 'apple',
  other: 'apples',
};

// Pluralize!

// I have 1 apple
const applesCount = 1;
console.log(`I have ${applesCount} ${pluralize(applesCount, variants)}`);

// She had 5 apples
const applesCount = 5;
console.log(`She had ${applesCount} ${pluralize(applesCount, variants)}`);

Browser

In browser environment you need to load all the locales that you are planning to use before initializing the instance of Numerous. This is done in order to provide optimal bundle size.
import * as numerous from 'numerous';

import enLocale from 'numerous/locales/en';
import ruLocale from 'numerous/locales/ru';

// Register single locale
numerous.registerLocale(enLocale);

// Or register multiple locales at the same time
numerous.registerLocale([
  enLocale,
  ruLocale,
]);

// Create an instance of Numerous
// using previously registered locale
const { pluralize } = numerous.create('en');

// Specify the list of variants
const variants = {
  one: 'apple',
  other: 'apples',
};

// Pluralize!

// I have 1 apple
const applesCount = 1;
console.log(`I have ${applesCount} ${pluralize(applesCount, variants)}`);

// She had 5 apples
const applesCount = 5;
console.log(`She had ${applesCount} ${pluralize(applesCount, variants)}`);

Without instantiating

You can use the library without instantiating it first. You just need to specify the locale on each call.
// "apple"
numerous.pluralize('en', 1, {
  one: 'apple',
  other: 'apples'
});

// "cats"
numerous.pluralize('en', 2, {
  one: 'cat',
  other: 'cats'
});
