A TypeScript library designed for managing localization and translations. It supports multiple languages, dynamic language switching, and provides a straightforward API for translation retrieval and pluralization.

• Multiple Languages Support: Easily manage translations across multiple languages.
• Dynamic Language Switching: Switch languages on the fly without reloading.
• Pluralization: Automatically handle plural forms of words based on count.
• Parameter Replacement: Dynamically insert values into translations.

Install the package using npm:

npm install @weirdscience/localization

Or using yarn:

yarn add @weirdscience/localization

First, import the localization object from the package:

import { localization } from "@weirdscience/localization";

Initialize the localization system with your default language, translations, and optionally a fallback language:

localization.init({
  defaultLang: "en",
  languages: {
    en: {
      greeting: "Hello, {{name}}!",
    },
    fr: {
      greeting: "Bonjour, {{name}}!",
    },
  },
  fallbackLang: "en",
});

Add or update translations for a specific language:

localization.addLanguage("es", {
  greeting: "Hola, {{name}}!",
});

Switch the current language:

localization.setLanguage("fr");

Get a translated string, with optional parameter replacement and pluralization:

// Simple translation
console.log(localization.t("greeting", { name: "John" }));

// Pluralization
console.log(localization.t("apple", {}, 5)); // apples

• init(options: { defaultLang?: string; languages: Languages; fallbackLang?: string; }): Initializes the localization system.
• addLanguage(lang: string, translations: Translations): Adds or updates translations for a language.
• setLanguage(lang: string): Sets the current language.
• t(key: string, params?: Record<string, string | number>, count?: number): Retrieves and formats a translation string.
