The tutorial guides users through creating a customizable News Aggregator app using Strapi, a Node.js-based headless CMS, and Nuxt.js, a framework for building universal Vue.js apps. It begins with setting up a Strapi project for the backend, where users create collection types for feed sources, news items, and subscribers, and configure CRON jobs to automate data fetching from RSS feeds. The tutorial then moves to building the frontend with Nuxt.js, including setting up a Nuxt.js project, integrating the @nuxtjs/strapi module, and designing pages for displaying news items and handling user subscriptions. Throughout the process, users learn about configuring API permissions, sanitizing HTML to prevent XSS attacks, and using Postman to test API endpoints. The tutorial concludes by suggesting deployment strategies for both the Strapi CMS and the Nuxt.js app, encouraging users to deploy on platforms like DigitalOcean and Netlify.
