What is the method for retrieving the locale value from the configuration in Next.js?

How can I retrieve the i18n.defaultLocale value from my Next.js app configuration? I thought it would be simple, but I'm struggling to find a clear solution for accessing the config settings in Next.js. Is there a specific built-in method for this, or should I just import the object exported by next.config.js?

If you want to access the locale information in your Next.js application, there are a few different approaches you can take depending on whether you're working on the client side or server side.

When working with React components on the client side, you can utilize the useRouter() hook provided by Next.js to easily retrieve the locale information, including the defaultLocale.

const { defaultLocale, locale, locales } = useRouter()
console.log(defaultLocale)

For server-side rendering using methods like getStaticProps, getStaticPaths, and getServerSideProps, the context object passed to these functions contains the necessary locale information.

export async function getStaticProps({ defaultLocale, locale, locales }) {
    console.log(defaultLocale)
    // ...
}

Additionally, when using getInitialProps, you can access the router object from the context to fetch the locale data.

Page.getInitialProps = async ({ router }) => {
    const { defaultLocale, locale, locales } = router
    console.log(defaultLocale)
    // ...
}
