The tutorial provides a detailed guide on building a multilingual news app using Strapi and React.js, emphasizing the use of Strapi's i18n plugin for content internationalization. Strapi, an open-source headless content management system, simplifies backend development by providing ready-made API endpoints for collections without requiring server code. The tutorial demonstrates setting up a Strapi project, creating a "newspost" collection with localization enabled, and adding English and French content. The React.js frontend is developed to interact with the Strapi backend, utilizing components for rendering news lists and individual news items, with language selection capabilities. The guide also covers creating a user interface for adding news entries, switching locales, and managing content, thus highlighting Strapi's efficiency in supporting multiple languages in web applications.
