How to Create a Multi-Language Website with Next.js

In our ever-connected world, the ability to reach a global audience has become a cornerstone of modern web development. Next.js, a powerful React framework, enables developers to create fast and scalable applications. By leveraging this framework, you can also craft a multi-language website that caters to diverse audiences, breaking the language barriers that often limit user engagement.

Understanding Internationalization (i18n) and Localization (l10n)

Internationalization, often abbreviated as i18n (because there are 18 letters between the 'i' and the 'n'), is the process of designing your web application to support multiple languages. Localization (l10n), the subsequent step, is the actual adaptation of the application to be language-specific, involving translation of content, date and time formatting, and more. The crux of a multi-language Next.js website lies in these two processes.

Setting Up Your Next.js Project

Before delving into the intricacies of i18n and l10n, you need to set up a basic Next.js project. Begin by executing...

npx create-next-app my-multilang-site

This command scaffolds a new Next.js project. Navigate through the project's file structure, familiarizing yourself with essential components like the pages directory, which holds the entry points of your application.

Choosing a Localization Library

Among the variety of i18n libraries available, next-i18next stands out due to its seamless integration with Next.js. It offers features like server-side rendering support and namespace management, which are pivotal for large-scale, multi-language projects.

Configuring Internationalized Routing

Next.js supports Internationalized Routing out of the box. You need to configure it in your next.config.js file:

module.exports = {
  i18n: {
    // These are all the locales you want to support in
    // your application
    locales: ["en", "fr", "es"],
    // This is the default locale you want to be used when visiting
    // a non-locale prefixed path e.g. `/hello`
    defaultLocale: "en",

With this setup, Next.js automatically handles routing for each locale. For instance, content in French would be accessible under /fr/.

Managing Translation Files

The heart of any multi-language application is its translation files. These are typically stored in a JSON or YAML format and contain key-value pairs where each key represents a unique piece of text within your application, and each value is its corresponding translation.

For a project using next-i18next, create a locales directory within your project. Inside this folder, have subdirectories for each language you support—like en, es, de, and so on. Each directory will have its own set of translation files that can be segmented into various namespaces for better organization.

Example of a translation file structure:

├── en
│   ├── common.json
│   └── home.json
├── es
│   ├── common.json
│   └── home.json

Implementing Language Switcher

The language switcher is a key component that allows users to select their preferred language. In a Next.js application using next-i18next, you might create a custom hook that taps into next-i18next's API to switch languages, or you could use their Link component to navigate between locales.

Here's an example of a language switcher button:

import { useTranslation } from 'next-i18next';

export default function LanguageSwitcher() {
    const { i18n } = useTranslation();

    const changeLanguage = (languageCode) => {

    return (
            <button onClick={() => changeLanguage('en')}>EN</button>
            <button onClick={() => changeLanguage('es')}>ES</button>
            {/* Add more buttons for other languages */}

Translating Content

With the setup complete, it's time to use these translations in your Next.js components. Using next-i18next, you can access your translation files with hooks or higher-order components (HOCs).

Here's how you can use the useTranslation hook:

import { useTranslation } from 'next-i18next';

export default function HomePage() {
    const { t } = useTranslation('home');

    return (
            {/* Other content */}

In this code snippet, t is a function provided by useTranslation that allows you to retrieve translated strings. The home parameter tells next-i18next to use translations from home.json.

Optimizing for SEO

SEO optimization is critical for multi-language sites. Different languages should have unique URLs, which can be achieved with Next.js's built-in internationalized routing.

Here’s how you can set up internationalized routing in next.config.js:

module.exports = {
    i18n: {
        locales: ['en', 'es', 'de'],
        defaultLocale: 'en',
    // ...other Next.js config

Then, to optimize for search engines, your pages should include the appropriate hreflang tags. These tags inform search engines which language you are using on a specific page, allowing them to serve the right content to the right users.

Testing and Deployment

Before deploying your multi-language Next.js site, thorough testing is crucial to ensure users have a seamless experience in their chosen language. Write unit tests for your localization functions, and perform manual testing by navigating through the site in different languages.

For deployment, Vercel is a popular choice for Next.js applications, offering an excellent platform for hosting with zero-config deployments.

To deploy your site with Vercel:

  1. Push your code to a Git provider (GitHub, GitLab, Bitbucket).
  2. Import your project into Vercel.
  3. Configure your project settings if necessary (e.g., add environment variables).
  4. Deploy your project with a click of a button or via commit.

Maintenance and Updating Content

Regularly maintaining and updating your content is vital for keeping your multi-language site relevant. Establish a process for updating translations — this might involve working with professional translators, using translation software, or gathering community contributions.

Consider using a Content Management System (CMS) that supports multi-language content for more straightforward updates. Some headless CMS options integrate well with Next.js, providing a backend system for managing translations.
