Creating localization files is a key step in developing a multilingual site with Next.js. These files store translations for different languages, making it easy to switch between them based on user preference or location. Let's see how you can set this up.
Start by creating a directory for your localization files, often named locales or dictionaries. Inside this directory, create JSON files for each language you want to support. These files will contain key-value pairs where the key is used in your code, and the value is the translated text.
Here's a basic example of how your en.json file might look:
{
"welcomeMessage": "Welcome to our site!",
"contactUs": "Contact Us",
"about": "About Us"
}
For a Spanish version, create an es.json file:
{
"welcomeMessage": "¡Bienvenido a nuestro sitio!",
"contactUs": "Contáctenos",
"about": "Sobre nosotros"
}
Similarly, you can create files like fr.json for French, de.json for German, and ar.json for Arabic. Here’s a snippet for the French file to illustrate:
{
"welcomeMessage": "Bienvenue sur notre site!",
"contactUs": "Contactez-nous",
"about": "À propos de nous"
}
These files are utilized within your Next.js app to display content in the selected language. By using libraries like next-i18next, you can easily manage these translations and ensure a smooth multilingual experience for your users. This setup is vital for reaching a broader audience and enhancing user engagement through localization. For more information on handling common challenges in MVP development with Next.js, including performance optimization and data fetching complexities, check out our detailed guide on navigating common challenges in Next.js MVP development.
Setting up translations in a Next.js project with next-i18next is straightforward. Start by installing the necessary packages. You'll need both next-i18next and react-i18next. Run this command:
npm install next-i18next react-i18next
Next, configure next-i18next. Create a next-i18next.config.js file in your project root. Here's a basic setup:
module.exports = {
i18n: {
locales: ['en', 'es', 'fr'],
defaultLocale: 'en',
},
};
This tells Next.js which languages you want to support and sets a default language.
Modify your next.config.js to include this configuration:
const { i18n } = require('./next-i18next.config');
module.exports = {
i18n,
};
Now, set up your translation files. Create a /public/locales directory. Inside this, make subfolders for each locale, like /en, /es, and /fr. Within each, create JSON files for your translations:
Example public/locales/en/common.json:
{
"welcome": "Welcome",
"goodbye": "Goodbye"
}
For Spanish, public/locales/es/common.json could look like:
{
"welcome": "Bienvenido",
"goodbye": "Adiós"
}
To use these translations in a component, leverage the useTranslation hook from next-i18next. Import it and call it within your component:
import { useTranslation } from 'next-i18next';
const MyComponent = () => {
const { t } = useTranslation('common');
return (
<div>
<h1>{t('welcome')}</h1>
</div>
);
};
This setup provides a seamless way to manage and display translations in your Next.js app, enhancing your site's global reach.

Fetching data based on a user's locale personalizes the experience. You can do this with getServerSideProps in Next.js. This function fetches data server-side, providing content based on language preferences.
Set up getServerSideProps in your page component. This function runs at request time, letting you access the incoming request's context. You can detect the user's locale and fetch the appropriate data here.
Here's how to set it up:
export async function getServerSideProps(context) {
const { locale } = context;
// Fetch data based on the locale
const response = await fetch(`https://api.example.com/data?lang=${locale}`);
const data = await response.json();
return {
props: { data }, // Pass data to the page component
};
}
const MyPage = ({ data }) => {
return (
<div>
<h1>{data.title}</h1>
<p>{data.description}</p>
</div>
);
};
export default MyPage;
This code uses the context parameter to detect the locale. The fetch call retrieves data specific to that locale. This shows users content in their language and region, improving their experience.

Serving locale-specific content connects you with a global audience and addresses their needs. It boosts user satisfaction and helps your site succeed internationally. Additionally, understanding static site generation in Next.js can further enhance your web development by converting websites into pre-rendered static HTML files for faster loading, improved security, and better SEO performance.
Handling localized routes in Next.js is straightforward and powerful. You can dynamically manage these routes, ensuring users experience the site in their preferred language. Start by using Next.js's built-in internationalized routing. This makes it easy to manage different language paths and serve the right content. For more insights on optimizing your Next.js applications, you might find our article on building large-scale applications with Next.js particularly useful.
Make the locale available to your components using the useRouter hook from Next.js. This hook lets you access the current locale and other routing details. Here's a quick example:
import { useRouter } from 'next/router';
const MyComponent = () => {
const { locale } = useRouter();
return <p>Current language: {locale}</p>;
};
For dynamic links, Next.js’s <Link> component is your go-to tool. Using <Link> helps maintain correct routing and ensures all paths reflect the user's language choice. It's crucial to use the pathname and query properties within <Link> to handle locales properly. Here's how you might set it up:
import Link from 'next/link';
const MyPage = () => {
return (
<div>
<Link href={{ pathname: '/', query: { lang: 'en' } }}>
<a>English</a>
</Link>
<Link href={{ pathname: '/', query: { lang: 'es' } }}>
<a>Español</a>
</Link>
</div>
);
};
This setup keeps links dynamic and aligned with the user's language preference. It ensures users can navigate seamlessly across different localized pages. By making locales available to components and using <Link> effectively, your app remains user-friendly and accessible to a global audience. Additionally, understanding the benefits of using Next.js for web app development can further enhance your project's performance and scalability.
Static generation with Next.js is a powerful way to deliver fast, SEO-friendly pages. When dealing with multilingual sites, you can use getStaticPaths and getStaticProps to create localized pages effortlessly. These functions help generate paths for each locale and fetch the necessary localized content.
Start by defining your paths with getStaticPaths. This function tells Next.js which locales and routes to generate at build time. Here’s a quick setup:
export async function getStaticPaths() {
const paths = [
{ params: { slug: 'home' }, locale: 'en' },
{ params: { slug: 'home' }, locale: 'es' },
{ params: { slug: 'home' }, locale: 'fr' },
];
return { paths, fallback: false };
}
In this example, paths are created for 'home' in English, Spanish, and French. This ensures each version of the page is pre-rendered and ready to go.
Next, use getStaticProps to fetch localized content. This function gets the data needed for each page based on the locale:
export async function getStaticProps({ params, locale }) {
const res = await fetch(`https://api.example.com/pages/${params.slug}?lang=${locale}`);
const pageData = await res.json();
return {
props: { pageData },
};
}
Here, getStaticProps fetches page data specific to each locale using the locale parameter. This way, your page displays the correct language content without delay.
By combining getStaticPaths and getStaticProps, you effectively manage and serve localized content. This approach optimizes load times and improves the user experience by showing the right content for each language. It’s a crucial step for building scalable, multilingual applications with Next.js. For a deeper understanding of how to leverage Static Site Generation in your projects, you can explore our detailed guide on Static Site Generation in Next.js.
Creating a functional language switcher in a Next.js app involves using the useRouter hook for seamless navigation between different locales. This setup allows users to switch languages without altering the current page's pathname or query parameters. It's all about providing a smooth transition that maintains the user’s context.
Start by importing the useRouter hook from next/router. This hook gives you access to the router instance, which is key to programmatically changing locales. Here’s a basic setup for a language switcher component:
import { useRouter } from 'next/router';
const LanguageSwitcher = () => {
const router = useRouter();
const { pathname, query, asPath } = router;
const changeLanguage = (locale) => {
router.push({ pathname, query }, asPath, { locale });
};
return (
<div>
<button onClick={() => changeLanguage('en')}>English</button>
<button onClick={() => changeLanguage('es')}>Español</button>
<button onClick={() => changeLanguage('fr')}>Français</button>
</div>
);
};
This component uses router.push to navigate to the same page in a different language. The current pathname and query are maintained, ensuring a seamless switch. The asPath parameter helps preserve URL structure, providing continuity in user navigation.
For a smooth user experience, ensure that your application handles language-specific data correctly. Preload necessary assets and translations to avoid delays. This proactive approach keeps the app responsive and user-friendly as it adapts to different languages.
