What is next-translate?

Next-translate is a great choice for managing your translations in your Next.js application. It is easy to configure and use, even for beginners. It supports basic internationalization (i18n) like plurals or Trans component (to use HTML inside translated text), loads only necessary translations which extremely saves your app memory, and it doesn't take a lot of storage.
