Installation

Getting up and running with I18XS is a breeze. Choose your preferred package manager from the options below and follow the simple installation steps:

NPM

npm i i18xs

Bun

bun i i18xs

Yarn

yarn add i18xs

Pnpm

pnpm install i18xs

 

Usage

Once you have installed I18XS, integrating it into your project is straightforward. Below are the basic steps to get you started:

First, import I18XS into your JavaScript or TypeScript file:

import I18XS from 'i18xs'

Then create a new instance for i18xs and pass the configuration to it:

const i18xs = new I18XS({
	supportedLocales: ['en'],
	currentLocale: 'en',
	fallbackLocale: 'en',
	rtlLocales: ['ar'],
})

And then you can use it like this:

const localizedMessage = i18xs.t('common.Hello_World') // -> Hello World

 

Documentation

The I18XS package comes with a comprehensive set of features designed to make internationalization in your application straightforward and efficient. This section provides an overview of its capabilities and guides on how to use them effectively.

• Features Overview

  • Simple Locale Management: Easily switch between languages in your application.
  • Dynamic Content Loading: Load language resources as needed, without bloating your application.
  • Pluralization and Formatting: Advanced support for plural forms and number formatting.
  • Customization and Extensibility: Extend or customize functionalities to fit your application’s needs.
  • LTR & RTL Detection: Detect LTR & RTL for easy access and usage

• Localization Files

  In multi-language applications, managing localization files is crucial. I18XS simplifies this process. Follow these guidelines to set up and utilize localization files effectively:

  • File Structure

    For each language supported by your application, create a folder for it in locales directory. These folders should be named using the locale's identifier, such as en for English, ar for Arabic, etc. Each file contains key-value pairs for localized strings.

    Example structure for the locales folder:

    /locales
        ├── /en
        │    ├── common.json
        │    ├── validation.json
        │    └── more JSON files...
        │
        ├── /fr
        │    ├── common.json
        │    ├── validation.json
        │    └── more JSON files...
        │
        └── /ar
             ├── common.json
             ├── validation.json
             └── more JSON files...
    

    Example structure for common.json:

    {
    	"Hello_World": "Hello World",
    	"Welcome_Message": "Welcome {name}",
    	"Items_Count": {
    		"zero": "No items",
    		"one": "One item",
    		"two": "Two items",
    		"other": "{itemsCount} items"
    	}
    }

  • Performance and Usage

    • Efficient Loading: I18XS optimizes performance by loading only the current locale's JSON file. This approach ensures faster load times and reduces memory usage.
    • Multiple Files per Locale: Each locale is represented by a folder and inside it multiple JSON files. This structure facilitates easier management and collaboration, also significantly enhancing performance and making it read faster.
    • Nested Objects Support: The library supports nested objects, allowing you to logically group related localizations for better organization.
    • Pluralization: I18XS handles plural localization, allowing different translations based on quantity (e.g., zero, one, two, other).

  • Integration

    • Single Language Setup: If your application only uses one language, you can create a single JSON file called common.json and use it directly.
    • Multiple Languages: For applications supporting multiple languages, store the localization files in the locales directory. Configure I18XS with the directory path, and it will dynamically load the appropriate file based on the current or changed locale.

• Usage & Configuration

  • Installation:

    Refer to the Installation section for instructions on how to install I18XS using various package managers.

  • Initializing the Library:

    You can create a new instance of I18XS and pass the configuration for it directly like this example below:

    const i18xs = new I18XS({
    	supportedLocales: ['en'],
    	currentLocale: 'en',
    	fallbackLocale: 'en',
    	showMissingIdentifierMessage: false,
    	missingIdentifierMessage: 'Missing_Localization_Identifier',
    	rtlLocales: ['ar'],
    	localesDir: './path/to/locales/folder',
    	showLogs: true,
    })

    Alternatively, you can split the creation of the new instance and the configuration, useful when split up into different modules for bootstrapping.

    const i18xs = new I18XS()
    
    i18xs.configure({
    	supportedLocales: ['en'],
    	currentLocale: 'en',
    	fallbackLocale: 'en',
    	showMissingIdentifierMessage: false,
    	missingIdentifierMessage: 'Missing_Localization_Identifier',
    	rtlLocales: ['ar'],
    	localesDir: './path/to/locales/folder',
    	showLogs: true,
    })

• Methods/Properties

  • Localize a message: You can localize a message by using one of those methods, the localization methods takes an identifier that contains the file name and the key you want to localize, for example, if the file name common.json and the message is Hello_World you can use it like this:

    i18xs.t('common.Hello_World') // -> Hello World
    i18xs.formatMessage('common.Hello_World') // -> Hello World

  • Localize a message in nested objects: You can localize a message using one of those methods

    i18xs.t('common.Foo.Bar.Hello_World') // -> Hello World

  • changeCurrentLocale: Use this method to change the current locale of I18XS

    i18xs.changeCurrentLocale('es') // -> Update the current locale

  • isCurrentLocale: Use this method to check if the current locale is what you looking for or not.

    i18xs.isCurrentLocale('es') // -> Update the current locale

  • hasIdentifier Check if a specific identifier exists in the localization object or not

    i18xs.hasIdentifier('Hello_World') // -> True || False

  • replaceData Replace the variables in the data object with the variables placeholder in the message

    i18xs.replaceData('Welcome {name}', { name: 'John Doe' }) // -> 'Welcome John Doe'

  • searchForLocalization Search for a localization with identifier and it will return a string message or the plural object for localization

    i18xs.searchForLocalization('common.Hello_World') // -> 'Hello World'
    i18xs.searchForLocalization('common.Items_Count') // -> {"zero": "No items", "one": "One item", "two": "Two items", "other": "{itemsCount} items" }

  • supportedLocales: Get the supported locale for the I18XS instance

    i18xs.supportedLocales // -> ['en', 'ar']

  • currentLocale: Understand how to change locales dynamically.

    i18xs.currentLocale // -> 'en'

  • fallbackLocale: Get the fallback locale to use it in case the current locale file is not found

    i18xs.fallbackLocale // -> 'en'

  • localization Get the localization object

    i18xs.fallbackLocale // -> 'en'

  • isCurrentLocaleLTR: Check if the current locale is Left-To-Right (LTR) or not

    i18xs.isCurrentLocaleLTR // -> True || False

  • isCurrentLocaleRTL: Check if the current locale is Right-To-Left (RTL) or not

    i18xs.isCurrentLocaleLTR // -> True || False

  • isShowLogs: Check if the debug mode is enabled or not

    i18xs.isShowLogs // -> True || False
