laravel-vue-lang

Localization for Vue and Laravel

This package allows to easily setup localization with a Laravel application using Vue. It is based on Lang.js.

Installation

$ yarn add laravel-vue-lang

With the Laravel Mix extension

This package ships with a Laravel Mix extension. You can include it and call .lang() on Mix. If for some reason your localization files are not in resources/lang, you can pass its path as a parameter.

Your webpack.mix.js should look like that:

const mix = require('laravel-mix');
require('laravel-vue-lang/mix');

mix
	// ...
	.lang();

Without the extension

If you prefer manual configuration, you will need to add a rule to load your translations, and a @lang alias that point to your lang directory. Your Mix configuration should look like this:

const mix = require('laravel-mix');

mix
	// ...
	.webpackConfig({
		resolve: {
			alias: {
				'@lang': path.resolve('./resources/lang'),
			},
		},
		module: {
			rules: [
				{
					test: /resources[\\\/]lang.+\.(php)$/,
					loader: 'php-array-loader',
				},
			],
		},
	});

Usage

Register the plugin in your Javascript:

import { Lang } from 'laravel-vue-lang';

// Register the plugin
Vue.use(Lang, {
	locale: 'fr',
	fallback: 'en',
	ignore: {
		fr: ['validation'],
	},
});

// Register Vue
const app = new Vue({
	el: '#app',
});

You can now use the following in any Vue file:

Function name	Description	Arguments
__()	Translates the given key, using optional replacements variables and the optional locale	key: string, replacements?: Replacements, locale?: string
$lang()	Returns the lang.js object.	None

Example:

<template>
	<div>
		<span>{{ __('messages.hello') }}</span>
	</div>
</template>

<script>
	export default {
		created() {
			console.log(this.__('messages.hello'));
		},
	};
</script>

Root-level translations

It is possible to have a root-level set of translations, such as a /resources/lang/fr.php instead of /resources/lang/fr/domain.php. You can use these translations by not specifying any domain while using the translate function.

// resources/lang/fr.php
<?php

return [
  'Hey you' => 'Salut toi'
];

<!-- Component.vue -->
<template>
	<div>
		<span>{{ __('Hey you') }}</span>
		<!-- Salut toi -->
	</div>
</template>

This is possible by working around lang.js and using a defined "global" domain. The actual translation key would be __global__.Hey you, but __global__ will be stripped so the fallback can be used if the translation is not found.

Options

locale and fallback

You can force a locale and define a fallback by using these two options. By default, the locale is determined using the HTML lang attribute. If it is empty, navigator.language is used instead.

If you use a translation key that can't be found, the fallback language will be used instead. If it still can't be found, the translation key will be returned.

ignore

You can ignore a localization file in a specific language by adding it to the ignore options.

ignore: {
  fr: ['validation'],
}

globalTranslationsKey

This is the key used to work around lang.js in order to implement root-level translations. The default is __global__, and you shouldn't need to change it.
