givanov95/laravel-translations

Multi-locale translation infrastructure for Laravel + Inertia + Vue projects.

What's included

• Translation polymorphic Eloquent model — store any model's translatable text per locale
• HasTranslation trait — setTranslation(), loadTranslations(), withTranslations() scope
• Translator service — cached JSON loader, getAllLocales(), model relation key mapping
• InitAppLocale + InitLocalePrefix middlewares
• MultiSelectService — load select options from any Eloquent model, with optional translation lookup
• MultiSelectDataConversion trait — turn a PHP enum into select option arrays
• TranslationPlugin.ts — Vue plugin exposing __('key', { name: 'value' })

The package is enum-agnostic — your project keeps its own Locale enum and passes either Locale::en or the plain 'en' string. Internally everything works with strings.

Install

composer require givanov95/laravel-translations
php artisan migrate
php artisan vendor:publish --tag=translations-frontend   # copies TranslationPlugin.ts
# optional:
php artisan vendor:publish --tag=translations-config
php artisan vendor:publish --tag=translations-migrations

Setup

1. Locale enum (project-side)

Create app/Enums/Locale.php in your project (the package doesn't ship one — locales differ per project):

namespace App\Enums;

enum Locale: string
{
    case en = 'en';
    case bg = 'bg';
}

2. Lang files

Create lang/en.json, lang/bg.json etc. with your translations:

{
    "Save": "Save",
    "Cancel": "Cancel"
}

3. Register middlewares (bootstrap/app.php)

use Givanov95\LaravelTranslations\Middleware\InitAppLocale;
use Givanov95\LaravelTranslations\Middleware\InitLocalePrefix;

$middleware->web(append: [
    InitAppLocale::class,
    InitLocalePrefix::class,
    \App\Http\Middleware\HandleInertiaRequests::class,
]);

4. Share with Inertia

In app/Http/Middleware/HandleInertiaRequests.php:

use Givanov95\LaravelTranslations\Translator;
use Illuminate\Support\Facades\App;

public function share(Request $request): array
{
    return array_merge_recursive(parent::share($request), [
        'locale'       => fn () => App::getLocale(),
        'translations' => fn () => Translator::translations(),
        // ...
    ]);
}

5. Install the Vue plugin (resources/js/app.ts)

import TranslationPlugin from '@/plugins/TranslationPlugin';

// inside createInertiaApp setup():
const translations = props.initialPage.props.translations as Record<string, string>;
app.use(TranslationPlugin, translations);

Usage

On models

use Givanov95\LaravelTranslations\Concerns\HasTranslation;

class Category extends Model
{
    use HasTranslation;
}

// staging + persisting:
$category->setTranslation('en', 'title', 'Shoes')
    ->setTranslation('bg', 'title', 'Обувки')
    ->save();

// eager-loading translations for current locale:
Category::withTranslations()->get();

// loading + key-indexing for a single model:
$category->loadTranslations();
$category->translations['title']->text;

Select options from a model

use Givanov95\LaravelTranslations\Services\MultiSelectService;

// untranslated (name column):
$options = (new MultiSelectService(Category::class))->dataForSelect();

// translated (translation row with key='title' for current locale):
$options = (new MultiSelectService(Category::class))->dataForSelectWithTranslations('title');

Enum to options

use Givanov95\LaravelTranslations\Concerns\MultiSelectDataConversion;

enum Status: string
{
    use MultiSelectDataConversion;
    case Active = 'active';
    case Draft = 'draft';
}

Status::forSelect();             // ['active' => 'Active', 'draft' => 'Draft']
Status::forSelectWithTranslate(); // [{id: 'active', name: __('Active')}, ...]

In Vue templates

<template>
    <h1>{{ __('Categories') }}</h1>
    <p>{{ __('Hello, :name', { name: user.name }) }}</p>
</template>

Development

composer install
composer test          # PHPUnit (16 tests)
composer analyse       # PHPStan level 5

Pre-commit hook

composer install / composer update symlinks the repo's pre-commit script into .git/hooks/pre-commit. It runs composer test + composer analyse before any commit that touches .php files — replacement for CI since the repo is private.

Bypass with git commit --no-verify when you genuinely need to (WIP commit, doc-only change you've already validated).
