The next-i18next config file
To configure next-i18next, a config file is required. In the project folder, create a new file and name it next-i18next.config.js .
List the locales in an array, and list the defaultLocale.
module.exports = {
i18n: {
// all the locales supported in the application
locales: ['en-GB', 'en-US'],
// the default locale to be used when visiting
// a non-localized route (e.g. `/about`)
defaultLocale: 'en-GB',
},
}
We will then set the fallback language. This is so if we can not provide the preferred language for a user, we can specify another language as fallback.
module.exports = {
i18n: {
// all the locales supported in the application
locales: ['en-GB', 'en-US'],
// the default locale to be used when visiting
// a non-localized route (e.g. `/about`)
defaultLocale: 'en-GB',
},
fallbackLng: 'en-GB',
}
We will then follow the same pattern for the namespaces. Stating the namespaces here allows us to use multiple files within a locale to access translations.
module.exports = {
i18n: {
// all the locales supported in the application
locales: ['en-GB', 'en-US'],
// the default locale to be used when visiting
// a non-localized route (e.g. `/about`)
defaultLocale: 'en-GB',
},
fallbackLng: 'en-GB',
ns: ['common', 'application', 'validation'],
defaultNS: 'application',
fallbackNS: 'common',
