### Step 1: Install Dependencies

Install the necessary packages using npm:

```bash packageManager="npm"
npm install intlayer vue-intlayer
npm install --save-dev nuxt-intlayer
npx intlayer init
```

```bash packageManager="pnpm"
pnpm add intlayer vue-intlayer
pnpm add --save-dev nuxt-intlayer
pnpm intlayer init
```

```bash packageManager="yarn"
yarn add intlayer vue-intlayer
yarn add --save-dev nuxt-intlayer
yarn intlayer init
```

```bash packageManager="bun"
bun add intlayer vue-intlayer
bun add --dev nuxt-intlayer
bunx intlayer init
```

- **intlayer**

  The core package that provides internationalization tools for configuration management, translation, [content declaration](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en/dictionary/content_file.md), transpilation, and [CLI commands](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en/cli/index.md).

- **vue-intlayer**
  The package that integrates Intlayer with Vue application. It the composables for the Vue components.

- **nuxt-intlayer**
  The Nuxt module that integrates Intlayer with Nuxt applications. It provides automatic setup, middleware for locale detection, cookie management, and URL redirection.

### Step 2: Configuration of your project

Create a config file to configure the languages of your application:

```typescript fileName="intlayer.config.ts" codeFormat="typescript"
import { Locales, type IntlayerConfig } from "intlayer";

const config: IntlayerConfig = {
  internationalization: {
    locales: [
      Locales.ENGLISH,
      Locales.FRENCH,
      Locales.SPANISH,
      // Your other locales
    ],
    defaultLocale: Locales.ENGLISH,
  },
};

export default config;
```

```javascript fileName="intlayer.config.mjs" codeFormat="esm"
import { Locales } from "intlayer";

/** @type {import('intlayer').IntlayerConfig} */
const config = {
  internationalization: {
    locales: [
      Locales.ENGLISH,
      Locales.FRENCH,
      Locales.SPANISH,
      // Your other locales
    ],
    defaultLocale: Locales.ENGLISH,
  },
};

export default config;
```

```javascript fileName="intlayer.config.cjs" codeFormat="commonjs"
const { Locales } = require("intlayer");

/** @type {import('intlayer').IntlayerConfig} */
const config = {
  internationalization: {
    locales: [
      Locales.ENGLISH,
      Locales.FRENCH,
      Locales.SPANISH,
      // Your other locales
    ],
    defaultLocale: Locales.ENGLISH,
  },
};

module.exports = config;
```

> Through this configuration file, you can set up localized URLs, middleware redirection, cookie names, the location and extension of your content declarations, disable Intlayer logs in the console, and more. For a complete list of available parameters, refer to the [configuration documentation](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en/configuration.md).

### Step 3: Integrate Intlayer in Your Nuxt Configuration

Add the intlayer module to your Nuxt configuration:

```typescript fileName="nuxt.config.ts"
import { defineNuxtConfig } from "nuxt/config";

export default defineNuxtConfig({
  // ... Your existing Nuxt configuration
  modules: ["nuxt-intlayer"],
});
```

> The `nuxt-intlayer` module automatically handles the integration of Intlayer with Nuxt. It sets up the content declaration building, monitors files in development mode, provides middleware for locale detection, and manages localized routing.

### Step 4: Declare Your Content

Create and manage your content declarations to store translations:

```tsx fileName="content/home-page.content.ts" contentDeclarationFormat="typescript"
import { type Dictionary, t } from "intlayer";

const content = {
  key: "home-page",
  content: {
    title: t({
      en: "Hello world",
      fr: "Bonjour le monde",
      es: "Hola mundo",
    }),
    metaTitle: t({
      en: "Welcome | My Application",
      fr: "Bienvenue | Mon Application",
      es: "Bienvenido | Mi Aplicación",
    }),
    metaDescription: t({
      en: "Discover your multilingual Nuxt app homepage powered by Intlayer.",
      fr: "Découvrez la page d'accueil multilingue de votre application Nuxt propulsée par Intlayer.",
      es: "Descubre la página de inicio multilingüe de tu aplicación Nuxt impulsada por Intlayer.",
    }),
  },
} satisfies Dictionary;

export default content;
```

> Your content declarations can be defined anywhere in your application as long as they are included in the `contentDir` directory (by default, `./src`). And match the content declaration file extension (by default, `.content.{json,ts,tsx,js,jsx,mjs,cjs}`).

> For more details, refer to the [content declaration documentation](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en/dictionary/content_file.md).

### Step 5: Utilize Intlayer in Your Code

Access your content dictionaries throughout your Nuxt application using the `useIntlayer` composable:

```vue fileName="components/HelloWorld.vue"
<script setup lang="ts">
import { ref } from "vue";
import { useIntlayer } from "vue-intlayer";

defineProps({
  msg: String,
});

const {
  count,
  edit,
  checkOut,
  nuxtIntlayer,
  learnMore,
  nuxtDocs,
  readTheDocs,
} = useIntlayer("helloworld");
const countRef = ref(0);
</script>

<template>
  <h1>{{ msg }}</h1>

  <div class="card">
    <button type="button" @click="countRef++">
      <count />
      {{ countRef }}
    </button>
    <p v-html="edit"></p>
  </div>

  <p>
    <checkOut />
    <a href="https://nuxt.com/docs/getting-started/introduction" target="_blank"
      >Nuxt</a
    >, <nuxtIntlayer />
  </p>
  <p>
    <learnMore />
    <a href="https://nuxt.com" target="_blank"><nuxtDocs /></a>.
  </p>
  <p class="read-the-docs"><readTheDocs /></p>
  <p class="read-the-docs">{{ readTheDocs }}</p>
</template>
```

#### Accessing Content in Intlayer

Intlayer offers different APIs to access your content:

- **Component-based syntax** (recommended):
  Use the `<myContent />`, or `<Component :is="myContent" />` syntax to render content as an Intlayer Node. This integrates seamlessly with the [Visual Editor](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en/intlayer_visual_editor.md) and [CMS](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en/intlayer_CMS.md).

- **String-based syntax**:
  Use `{{ myContent }}` to render the content as plain text, without Visual Editor support.

- **Raw HTML syntax**:
  Use `<div v-html="myContent" />` to render the content as raw HTML, without Visual Editor support.

- **Destructuration syntax**:
  The `useIntlayer` composable returns an Proxy with the content. This proxy can be destructured to access the content while keeping the reactivity.
  - Use `const content = useIntlayer("myContent");` And `{{ content.myContent }}` / `<content.myContent />`.
  - Or use `const { myContent } = useIntlayer("myContent");` And `{{ myContent}}` / `<myContent/>` to destructure the content.

### (Optional) Step 6: Change the language of your content

To change the language of your content, you can use the `setLocale` function provided by the `useLocale` composable. This function allows you to set the locale of the application and update the content accordingly.

Create a component to switch between languages using `NuxtLink`. **Using links instead of buttons for locale switching is a best practice for SEO and page discoverability**, as it allows search engines to crawl and index all localized versions of your pages:

```vue fileName="components/LocaleSwitcher.vue"
<script setup lang="ts">
import { getLocaleName, getLocalizedUrl } from "intlayer";
import { useLocale } from "vue-intlayer";

// Nuxt auto-imports useRoute
const route = useRoute();
const { locale, availableLocales, setLocale } = useLocale();
</script>

<template>
  <nav class="locale-switcher">
    <NuxtLink
      v-for="localeEl in availableLocales"
      :key="localeEl"
      :to="getLocalizedUrl(route.fullPath, localeEl)"
      class="locale-link"
      :class="{ 'active-locale': localeEl === locale }"
      @click="setLocale(localeEl)"
    >
      {{ getLocaleName(localeEl) }}
    </NuxtLink>
  </nav>
</template>
```

> Using `NuxtLink` with proper `href` attributes (via `getLocalizedUrl`) ensures that search engines can discover all language variants of your pages. This is preferable to JavaScript-only locale switching, which search engine crawlers may not follow.

Then, set up your `app.vue` to use layouts:

```vue fileName="app.vue"
<template>
  <NuxtLayout>
    <NuxtPage />
  </NuxtLayout>
</template>
```

### (Optional) Step 6b: Create a Layout with Navigation

Nuxt layouts allow you to define a common structure for your pages. Create a default layout that includes the locale switcher and navigation:

```vue fileName="layouts/default.vue"
<script setup lang="ts">
import Links from "~/components/Links.vue";
import LocaleSwitcher from "~/components/LocaleSwitcher.vue";
</script>

<template>
  <div>
    <header>
      <LocaleSwitcher />
    </header>
    <main>
      <slot />
    </main>

    <Links href="/">Home</Links>
    <Links href="/about">About</Links>
  </div>
</template>
```

The `Links` component (shown below) ensures that internal navigation links are automatically localized.

### (Optional) Step 7: Add localized Routing to your application

Nuxt automatically handles localized routing when using the `nuxt-intlayer` module. This creates routes for each language automatically based on your pages directory structure.

Example:

```plaintext
pages/
├── index.vue          → /, /fr, /es
├── about.vue          → /about, /fr/about, /es/about
└── contact/
    └── index.vue      → /contact, /fr/contact, /es/contact
```

To create localized pages, simply create your Vue files in the `pages/` directory. Here are two example pages:

**Home page (`pages/index.vue`):**

```vue fileName="pages/index.vue"
<script setup lang="ts">
import { useIntlayer } from "vue-intlayer";

const content = useIntlayer("home-page");

useHead({
  title: content.metaTitle.raw,
  meta: [
    {
      name: "description",
      content: content.metaDescription.raw,
    },
  ],
});
</script>

<template>
  <h1><content.title /></h1>
</template>
```

**About page (`pages/about.vue`):**

```vue fileName="pages/about.vue"
<script setup lang="ts">
import { useIntlayer } from "vue-intlayer";

const content = useIntlayer("about-page");

useHead({
  title: content.metaTitle.raw, // Use .raw for primitive string access
  meta: [
    {
      name: "description",
      content: content.metaDescription.raw, // Use .raw for primitive string access
    },
  ],
});
</script>

<template>
  <h1><content.title /></h1>
</template>
```

> Note: `useHead` is auto-imported in Nuxt. You can access content values using either `.value` (reactive) or `.raw` (primitive string) depending on your needs.

The `nuxt-intlayer` module will automatically:

- Detect the user's preferred locale
- Handle locale switching via URL
- Set the appropriate `<html lang="">` attribute
- Manage locale cookies
- Redirect users to the appropriate localized URL

### (Optional) Step 8: Creating a Localized Link Component

To ensure that your application's navigation respects the current locale, you can create a custom `Links` component. This component automatically prefixes internal URLs with the current language, which is essential for **SEO and page discoverability**.

```vue fileName="components/Links.vue"
<script setup lang="ts">
import { getLocalizedUrl } from "intlayer";
import { useLocale } from "vue-intlayer";

interface Props {
  href: string;
  locale?: string;
}

const props = defineProps<Props>();

const { locale: currentLocale } = useLocale();

// Compute the final path
const finalPath = computed(() => {
  // 1. Check if the link is external
  const isExternal = /^https?:\/\//.test(props.href || "");

  // 2. If external, return as is (NuxtLink handles the <a> tag generation)
  if (isExternal) return props.href;

  // 3. If internal, localize the URL
  const targetLocale = props.locale || currentLocale.value;
  return getLocalizedUrl(props.href, targetLocale);
});
</script>

<template>
  <NuxtLink :to="finalPath" v-bind="$attrs">
    <slot />
  </NuxtLink>
</template>
```

Then use this component throughout your application:

```vue fileName="layouts/default.vue"
<script setup lang="ts">
import Links from "~/components/Links.vue";
import LocaleSwitcher from "~/components/LocaleSwitcher.vue";
</script>

<template>
  <div>
    <header>
      <LocaleSwitcher />
    </header>
    <main>
      <slot />
    </main>

    <Links href="/">Home</Links>
    <Links href="/about">About</Links>
  </div>
</template>
```

> By using `NuxtLink` with localized paths, you ensure that:
>
> - Search engines can crawl and index all language versions of your pages
> - Users can share localized URLs directly
> - Browser history works correctly with locale-prefixed URLs

### (Optional) Step 9: Handle Metadata and SEO

Nuxt provides excellent SEO capabilities via the `useHead` composable (auto-imported). You can use Intlayer to handle localized metadata using the `.raw` or `.value` accessor to get the primitive string value:

```vue fileName="pages/about.vue"
<script setup lang="ts">
import { useIntlayer } from "vue-intlayer";

// useHead is auto-imported in Nuxt
const content = useIntlayer("about-page");

useHead({
  title: content.metaTitle.raw, // Use .raw for primitive string access
  meta: [
    {
      name: "description",
      content: content.metaDescription.raw, // Use .raw for primitive string access
    },
  ],
});
</script>

<template>
  <h1><content.title /></h1>
</template>
```

> Alternatively, you can use the `import { getIntlayer } from "intlayer"` function to get the content without Vue reactivity.

> **Accessing content values:**
>
> - Use `.raw` to get the primitive string value (non-reactive)
> - Use `.value` to get the reactive value
> - Use `<content.key />` component syntax for Visual Editor support

Create the corresponding content declaration:

```ts fileName="pages/about-page.content.ts" contentDeclarationFormat="typescript"
import { t, type Dictionary } from "intlayer";

const aboutPageContent = {
  key: "about-page",
  content: {
    metaTitle: t({
      en: "About Us - My Company",
      fr: "À Propos - Ma Société",
      es: "Acerca de Nosotros - Mi Empresa",
    }),
    metaDescription: t({
      en: "Learn more about our company and our mission",
      fr: "En savoir plus sur notre société et notre mission",
      es: "Conozca más sobre nuestra empresa y nuestra misión",
    }),
    title: t({
      en: "About Us",
      fr: "À Propos",
      es: "Acerca de Nosotros",
    }),
  },
} satisfies Dictionary;

export default aboutPageContent;
```

```javascript fileName="pages/about-page.content.mjs" contentDeclarationFormat="esm"
import { t } from "intlayer";

/** @type {import('intlayer').Dictionary} */
const aboutPageContent = {
  key: "about-page",
  content: {
    metaTitle: t({
      en: "About Us - My Company",
      fr: "À Propos - Ma Société",
      es: "Acerca de Nosotros - Mi Empresa",
    }),
    metaDescription: t({
      en: "Learn more about our company and our mission",
      fr: "En savoir plus sur notre société et notre mission",
      es: "Conozca más sobre nuestra empresa y nuestra misión",
    }),
    title: t({
      en: "About Us",
      fr: "À Propos",
      es: "Acerca de Nosotros",
    }),
  },
};

export default aboutPageContent;
```

```javascript fileName="pages/about-page.content.cjs" contentDeclarationFormat="commonjs"
const { t } = require("intlayer");

/** @type {import('intlayer').Dictionary} */
const aboutPageContent = {
  key: "about-page",
  content: {
    metaTitle: t({
      en: "About Us - My Company",
      fr: "À Propos - Ma Société",
      es: "Acerca de Nosotros - Mi Empresa",
    }),
    metaDescription: t({
      en: "Learn more about our company and our mission",
      fr: "En savoir plus sur notre société et notre mission",
      es: "Conozca más sobre nuestra empresa y nuestra misión",
    }),
    title: t({
      en: "About Us",
      fr: "À Propos",
      es: "Acerca de Nosotros",
    }),
  },
};

module.exports = aboutPageContent;
```

```json fileName="pages/about-page.content.json" contentDeclarationFormat="json"
{
  "$schema": "https://intlayer.org/schema.json",
  "key": "about-page",
  "content": {
    "metaTitle": {
      "nodeType": "translation",
      "translation": {
        "en": "About Us - My Company",
        "fr": "À Propos - Ma Société",
        "es": "Acerca de Nosotros - Mi Empresa"
      }
    },
    "metaDescription": {
      "nodeType": "translation",
      "translation": {
        "en": "Learn more about our company and our mission",
        "fr": "En savoir plus sur notre société et notre mission",
        "es": "Conozca más sobre nuestra empresa y nuestra misión"
      }
    },
    "title": {
      "nodeType": "translation",
      "translation": {
        "en": "About Us",
        "fr": "À Propos",
        "es": "Acerca de Nosotros"
      }
    }
  }
}
```

### Git Configuration

It is recommended to ignore the files generated by Intlayer. This allows you to avoid committing them to your Git repository.

To do this, you can add the following instructions to your `.gitignore` file:

```plaintext fileName=".gitignore"
# Ignore the files generated by Intlayer
.intlayer
```

### VS Code Extension

To improve your development experience with Intlayer, you can install the official **Intlayer VS Code Extension**.

[Install from the VS Code Marketplace](https://marketplace.visualstudio.com/items?itemName=intlayer.intlayer-vs-code-extension)

This extension provides:

- **Autocompletion** for translation keys.
- **Real-time error detection** for missing translations.
