Setting a Default Language

Setting a default language in your Next.js Firebase application is easy.

Simply set the environment variable DEFAULT_LOCALE to the language code you want to use as the default language.

By default, we use en as the default language. If you want to change it, simply add the following line to your .env file. For example, if you want to use Spanish as the default language, you would add the following line to your .env file:

DEFAULT_LOCALE=es
