What is Intlayer?

Intlayer is an innovative, open-source internationalization (i18n) library designed to simplify multilingual support in modern web applications.

With Intlayer, you can:

• Easily manage translations using declarative dictionaries at the component level.
• Dynamically localize metadata, routes, and content.
• Ensure TypeScript support with autogenerated types, improving autocompletion and error detection.
• Benefit from advanced features, like dynamic locale detection and switching.

Step-by-Step Guide to Set Up Intlayer in a Vite and Angular Application

Step 1: Install Dependencies

Install the necessary packages using npm:

npm install intlayer angular-intlayer vite-intlayer

• intlayer

  The core package that provides internationalization tools for configuration management, translation, content declaration, transpilation, and CLI commands.

• angular-intlayer The package that integrates Intlayer with Angular application. It provides context providers and hooks for Angular internationalization.

Step 2: Configuration of your project

Create a config file to configure the languages of your application:

import { Locales, type IntlayerConfig } from "intlayer";const config: IntlayerConfig = {  internationalization: {    locales: [      Locales.ENGLISH,      Locales.FRENCH,      Locales.SPANISH,      // Your other locales    ],    defaultLocale: Locales.ENGLISH,  },};export default config;

Through this configuration file, you can set up localized URLs, middleware redirection, cookie names, the location and extension of your content declarations, disable Intlayer logs in the console, and more. For a complete list of available parameters, refer to the configuration documentation.
