Strapi, a headless content management system, facilitates internationalization through its i18n plugin, allowing developers to create and manage localized content across different languages or locales. The article guides users in implementing internationalization in Strapi applications using an eCommerce template, demonstrating how to add and manage multiple locales such as English and French. It explains the difference between internationalization and localization, emphasizing the plugin's role in allowing admins to store and serve content specific to user locales without automatic translation. The tutorial also includes setting up a Gatsby front-end application to fetch and display localized content using GraphQL, providing a practical example of linking a Strapi back-end with a Gatsby front-end to dynamically present localized product data. The guide offers insights into using GraphQL queries to retrieve data from Strapi and creating dynamic pages in Gatsby based on locale-specific content. This process enhances user engagement by providing content tailored to diverse cultural and linguistic audiences, showcasing the ease of integrating internationalization features using Strapi and Gatsby.
