Strapi has an i18n localization plugin that can handle internationalization and localization effectively, making it easy to build applications for an international audience. The plugin requires configuration to take effect on the Strapi admin dashboard and involves installing and adding locales, creating content types, managing content, and using the API to fetch localized data. The plugin has excellent features such as add locale content, editing field's locale, and leveraging the API to create localized entries for posts. To use the plugin, one needs to have a Strapi application running on version 3.6.0 or higher, install the i18n plugin using NPM or Yarn commands, activate the plugin, and configure it properly. Some best practices when working with Strapi include adopting the Jamstack architecture, consuming the API with any front-end framework of choice, and checking the documentation for more information on Strapi.
