# Lang Sync Inertia

## When to Apply

Apply this skill when working on:
- syncing Laravel language files to Inertia frontends
- `syncLangFiles()` usage or implementation
- `Inertia::share('lang', ...)`
- frontend translation APIs for Vue or React
- generated JSON language export support
- locale-aware translation loading
- package installation, publishing, or commands
- backward-compatible API design for `lang()`, `vueLang()`, and `reactLang()`
- debugging missing or stale translation data

## Package Purpose

This package bridges Laravel backend translations with Inertia.js frontends.

It currently:
- provides a global helper `syncLangFiles(string|array $fileName): array`
- loads translation data through the package `Lang` facade
- shares translations to the frontend through `Inertia::share('lang', ...)`
- merges runtime-loaded translations with generated JSON translations
- resolves generated JSON per current Laravel locale
- supports frontend consumption through the companion NPM package
- supports Vue and React consumers

## Current Architecture

### Helper
- `syncLangFiles()` is defined in `src/LangHelpers.php`
- it delegates to `Lang::getFile($fileName)`

### Service provider
`LangSyncInertiaServiceProvider` is responsible for:
- merging config from `config/inertia-lang.php`
- registering package commands
- publishing config
- requiring helpers
- registering alias `Lang`
- pushing middleware `ShareLangTranslations`
- sharing `lang` data with Inertia

### Shared translation flow
The package shares translations with:

```php
Inertia::share('lang', function () {
    $locale = app()->getLocale();

    $runtimeLang = Lang::getLoaded();
    $jsonLang = $this->loadGeneratedLangJson($locale);

    return $jsonLang
        ? array_replace_recursive($jsonLang, $runtimeLang)
        : $runtimeLang;
});
