Project Structure

The project structure is designed for clarity and ease of use:

├── public/
├── messages/
│       └── en.json
│       └── {locale1}.json
│
├── src/
│   └── pages/
│       └── index.astro (redirects to pages/en/)
│   └── pages/en/
│       └── index.astro
│   └── pages/{locale1}/
│       └── index.astro
│
└── package.json

Localization Files: The messages/ directory contains JSON files for each locale, allowing for easy management of translations. For example, messages/en.json might look like this:

{
  "welcome": "Welcome to our website!",
  "description": "This is a multilingual site."
}

Dynamic Routing: The project supports dynamic routing based on language, allowing for clean URLs. For instance, the structure allows for both src/pages/en/index.astro and src/pages/es/index.astro.

Commands

The template provides a set of commands to streamline development:

Command	Action
`npm install`	Installs dependencies
`npm run postinstall`	Compiles translations
`npm run dev`	Starts local dev server at `localhost:4321`
`npm run build`	Build your production site to `./dist/`
`npm run preview`	Preview your build locally, before deploying

For example, running npm run dev starts a local development server, allowing developers to see changes in real-time.

4. Technical Challenges Overcome

Internationalization Setup

Setting up internationalization can be complex, especially when managing multiple languages. The template simplifies this process by providing clear instructions for adding new locales:

Update languageTags in ./project.inlang/settings.json.
