Vue Laravel Breeze i18n
November 4, 2024 · AI Conversations
### Step 1: Install Vue I18n
If you haven't already, install the `vue-i18n` package. You can do this using npm or yarn:
npm install vue-i18n
# or
yarn add vue-i18n
### Step 2: Create Language Files
Create a folder to store your language files. This is typically done in the `resources/js` directory of your Laravel project. For example:
resources/js/locales
Inside the `locales` folder, create JSON files for each language. For example:
– `en.json` (for English)
– `fr.json` (for French)
Each JSON file should contain key-value pairs for your translations:
**en.json**
{
"welcome": "Welcome to our application",
"login": "Login",
"register": "Register"
}
**fr.json**
{
"welcome": "Bienvenue dans notre application",
"login": "Connexion",
"register": "S'inscrire"
}
### Step 3: Set Up Vue I18n
In your main Vue entry file (usually `app.js` or `main.js`), import and configure `vue-i18n`:
import { createApp } from 'vue';
import { createI18n } from 'vue-i18n';
import App from './App.vue'; // Your main component
import en from './locales/en.json';
import fr from './locales/fr.json';
const messages = {
en: en,
fr: fr,
};
const i18n = createI18n({
locale: 'en', // set default locale
messages,
});
const app = createApp(App);
app.use(i18n);
app.mount('#app');
### Step 4: Use Translations in Your Components
You can use the `$t` method provided by `vue-i18n` to translate text in your Vue components:
<template>
<div>
<h1>{{ $t('welcome') }}</h1>
<router-link to="/login">{{ $t('login') }}</router-link>
<router-link to="/register">{{ $t('register') }}</router-link>
</div>
</template>
### Step 5: Switching Languages
You can implement a method to switch languages dynamically. For example:
<template>
<div>
<h1>{{ $t('welcome') }}</h1>
<button @click="changeLanguage('en')">English</button>
<button @click="changeLanguage('fr')">Français</button>
</div>
</template>
<script>
export default {
methods: {
changeLanguage(locale) {
this.$i18n.locale = locale;
},
},
};
</script>
### Step 6: Persisting Language Preference (Optional)
To remember the user's language preference, you can store it in localStorage or a cookie:
changeLanguage(locale) {
this.$i18n.locale = locale;
localStorage.setItem('locale', locale);
},
mounted() {
const savedLocale = localStorage.getItem('locale');
if (savedLocale) {
this.$i18n.locale = savedLocale;
}
}
### Conclusion
By following these steps, you can easily set up internationalization in your Vue.js application using Laravel Breeze. You can extend this setup by adding more languages and refining your translation keys as needed. If you have any specific questions or need help with a particular aspect, feel free to ask!

// app.component('NavBar', NavBar);
// Mount the app
app.mount(el);
},
progress: {
color: '#4B5563',
},
});
// Optional: Method to change the language dynamically and store in local storage
function changeLanguage(locale) {
i18n.global.locale = locale; // Change the locale
localStorage.setItem('lang', locale); // Save the preference in local storage
}
// Example usage: changeLanguage('es') to switch to Spanish
### Key Adjustments and Additions:
1. **Global Translation Function**: I prefixed `$t` for the translation function in `globalProperties` for clarity. It's a common convention in Vue to prefix with `$` for global properties.
2. **Dynamic Language Change Function**: Added a `changeLanguage` function that you can call to switch languages and store the selection in `localStorage`. You can invoke this function in your components to change languages dynamically.
3. **Commented Out Global Component Registration**: If you have any global components (like a navbar), you can register them in the commented section.
### Usage of Language Change
You can use the `changeLanguage` function within your Vue components like this:
<template>
<div>
<h1>{{ $t('welcome') }}</h1>
<button @click="changeLanguage('en')">English</button>
<button @click="changeLanguage('es')">Español</button>
</div>
</template>
<script>
export default {
methods: {
changeLanguage(locale) {
this.$t(locale); // Call the translation method
this.$root.changeLanguage(locale); // Call the global function to change language
}
}
};
</script>
### Conclusion
With these adjustments, your setup for internationalization in a Vue.js application using Laravel Breeze and Inertia.js should be functional and organized. If you have any further questions or need additional features, feel free to ask!
### Option 1: Using `provide` and `inject`
You can provide the `changeLanguage` function from the root app instance and inject it into your components. Here's how to do it:
#### 1. Modify Your `app.js` to Provide the Function
In your `setup` function of the Inertia app, you can use the `provide` method:
// In your app.js or main.js file
import { createInertiaApp } from '@inertiajs/vue3';
// ... other imports
createInertiaApp({
title: (title) => `${title} - ${appName}`,
resolve: (name) =>
resolvePageComponent(
`./Pages/${name}.vue`,
import.meta.glob('./Pages/**/*.vue'),
),
setup({ el, App, props, plugin }) {
const app = createApp({ render: () => h(App, props) });
// Provide the changeLanguage function
app.provide('changeLanguage', changeLanguage);
// Use plugins
app.use(i18n);
app.use(plugin);
app.use(ZiggyVue);
app.config.globalProperties.$t = (...args) => i18n.global.t(...args);
// Mount the app
app.mount(el);
},
progress: {
color: '#4B5563',
},
});
// Define the changeLanguage function
function changeLanguage(locale) {
i18n.global.locale = locale; // Change the locale
localStorage.setItem('lang', locale); // Save the preference in local storage
}
#### 2. Inject the Function in Your Component
In your Vue component, you can now inject and use the `changeLanguage` function:
<template>
<div>
<h1>{{ $t('welcome') }}</h1>
<button @click="changeLang('en')">English</button>
<button @click="changeLang('es')">Español</button>
</div>
</template>
<script>
import { inject } from 'vue';
export default {
setup() {
const changeLanguage = inject('changeLanguage');
// Define a wrapper function to call the injected function
const changeLang = (locale) => {
if (changeLanguage) {
changeLanguage(locale); // Call the provided function
}
};
return {
changeLang,
};
},
};
</script>
### Option 2: Directly Define the Function in the Component
Alternatively, you can define the `changeLanguage` function directly within each component where you need it:
<template>
<div>
<h1>{{ $t('welcome') }}</h1>
<button @click="changeLang('en')">English</button>
<button @click="changeLang('es')">Español</button>
</div>
</template>
<script>
import { toRefs } from 'vue';
export default {
setup() {
const changeLanguage = (locale) => {
i18n.global.locale = locale; // Change the locale
localStorage.setItem('lang', locale); // Save the preference in local storage
};
// Define a wrapper function to call the injected function
const changeLang = (locale) => {
changeLanguage(locale); // Call the provided function
};
return {
changeLang,
};
},
};
</script>
### Conclusion
Both options should solve the issue. The first option is more modular as it allows you to define the language-changing logic in one place, while the second option keeps everything self-contained within the component. Choose the one that best fits your application architecture. If you need further assistance, feel free to ask!
