Plugins and Utils

i18n formats

While the i18next format (JSON based) is the preferred solution and widely supported in translation management tools like locize.com, you might prefer another exciting format, like:

name	format	description
i18next-fluent	fluent	i18nFormat plugin to use mozilla fluent format with i18next
i18next-icu	ICU	i18nFormat plugin to use ICU format with i18next based on yahoo/intl-messageformat
i18next-polyglot	polyglot	i18nFormat plugin to use airbnb/polyglot.js format with i18next
i18next-shopify	Shopify json format	It allows developers to use the same format used by Shopify apps and themes for localization

In general, using an i18n format plugin, will remove the i18next specific format functionality, like plurals, interpolation, context, etc... you need to use the format requested in the used i18n format.
