Using Laravel translations in Javascript with the Laravel Translations Loader

 Have you ever wanted to use the same Laravel translations you use on the back-end in your front-end code?

Laravel Translations Loader is a webpack loader that enables you to load your Laravel translations into your javascript bundle.

Instead of doing HTTP requests to fetch translations, the package enters in the middle of the asset compilation process and translates your PHP translation files (JSON and PHP) into a JSON object so you can use however you like.

It works out of the box with packages like vue-i18n or with a few configuration tweaks with the popular i18next package.

Show me the code

The first step, is to install the package using NPM or Yarn.

1npm install @kirschbaum-development/laravel-translations-loader --save
2yarn add @kirschbaum-development/laravel-translations-loader --save

Or, by using Yarn.

1npm install @kirschbaum-development/laravel-translations-loader --save

Basically, in your javascript file, you just need to include the following line to import your language bundle.

1import languageBundle from
2'@kirschbaum-development/laravel-translations-loader!@kirschbaum-development/laravel-translations-loader';

This will load and parse all your language files, including PHP and JSON translations. The languageBundle will look something like this:

 1{
 2    "en": {
 3        "auth": {
 4            "failed": "These credentials do not match our records."
 5        }
 6    },
 7    "es": {
 8        "auth": {
 9            "failed": "Estas credenciales no coinciden con nuestros registros."
10        }
11    }
12}

Along with all other translations you may have on your translations folder.

There are options for loading either just PHP or JSON translations files, as well as adding a namespace between the lang keys and the actual translations that some packages require. You can check the different loading options on the readme of the project. And please fill out an issue if you have any troubles or suggestions.

Example using vue–i18n

Notice you can directly pass the languageBundle object as a parameter into the VueI18n constructor.

1import languageBundle from '@kirschbaum-development/laravel-translations-loader!@kirschbaum-development/laravel-translations-loader';
2import VueI18n from 'vue-i18n';
3Vue.use(VueI18n);
4const i18n = new VueI18n({
5    locale: window.Locale,
6    messages: languageBundle,
7})

And on any vue component, you can just use the $t function, like the following example:

1<template>
2    <span>{{ $t('auth.failed') }}</span>
3    <!-- this will output the same as {{ trans('auth.failed') }} using Laravel -->
4</template>

Generate Migrations from an Existing Database With the Migration Generator Package

 

Laravel Migration Generator

Migration Generator for Laravel is a package by Bennett Treptow to generate migrations from existing database structures:

A primary use case for this package would be a project that has many migrations that alter tables using ->change() from doctrine/dbal that SQLite doesn't support and need a way to get table structures updated for SQLite to use in tests. Another use case would be taking a project with a database and no migrations and turning that database into base migrations.

This package could be helpful if you are porting an existing application into Laravel and want to re-create the database migrations for the application to help with development and testing.

To visualize how this process works, the readme has example usage which defines the following users table:

 1CREATE TABLE `users` (
 2  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 3  `username` varchar(128) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 4  `email` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 5  `password` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 6  `first_name` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 7  `last_name` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 8  `timezone` varchar(45) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT 'America/New_York',
 9  `location_id` int(10) unsigned NOT NULL,
10  `deleted_at` timestamp NULL DEFAULT NULL,
11  `remember_token` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
12  `created_at` timestamp NULL DEFAULT NULL,
13  `updated_at` timestamp NULL DEFAULT NULL,
14  PRIMARY KEY (`id`),
15  KEY `users_username_index` (`username`),
16  KEY `users_first_name_index` (`first_name`),
17  KEY `users_last_name_index` (`last_name`),
18  KEY `users_email_index` (`email`),
19  KEY `fk_users_location_id_index` (`location_id`)
20  CONSTRAINT `users_location_id_foreign` FOREIGN KEY (`location_id`) REFERENCES `locations` (`id`) ON UPDATE CASCADE ON DELETE CASCADE
21) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Using this package, you can run the following command to generate a blueprint class based on the table definition:

1php artisan generate:migrations

And the derived blueprint from the users table would look as follows according to the example:

 1use Illuminate\Support\Facades\Schema;
 2use Illuminate\Database\Schema\Blueprint;
 3use Illuminate\Database\Migrations\Migration;
 4 
 5class CreateUsersTable extends Migration
 6{
 7    /**
 8     * Run the migrations.
 9     *
10     * @return void
11     */
12    public function up()
13    {
14        Schema::create('users', function (Blueprint $table) {
15            $table->increments('id');
16            $table->string('username', 128)->nullable()->index();
17            $table->string('email', 255)->index();
18            $table->string('password', 255);
19            $table->string('first_name', 45)->nullable()->index();
20            $table->string('last_name', 45)->index();
21            $table->string('timezone', 45)->default('America/New_York');
22            $table->unsignedInteger('location_id');
23            $table->softDeletes();
24            $table->string('remember_token', 255)->nullable();
25            $table->timestamps();
26            $table->foreign('location_id', 'users_location_id_foreign')->references('id')->on('locations')->onUpdate('cascade')->onDelete('cascade');
27        });
28    }
29 
30    /**
31     * Reverse the migrations.
32     *
33     * @return void
34     */
35    public function down()
36    {
37        Schema::dropIfExists('users');
38    }
39}

The package also comes with various table and view migration stubs and configuration settings. For example, a configuration defining the filename patterns used to generate table schema:

1return [
2    'table_naming_scheme' => '[Timestamp]_create_[TableName]_table.php',
3    // ...
4];

At the time of writing the package supports MySQL, but could also support Postgres, SQLite, and SQL Server according the the readme.
