Here is a neutral, objective, and concise summary of the provided text: Strapi is a headless CMS built using Node.js that has gained popularity due to its unique plugin design pattern and flat learning curve. It can be consumed with various JavaScript front-end frameworks or core HTML/CSS/JavaScript. Strapi ships with several authentication providers, including Facebook, which is used in this tutorial. To implement Facebook authentication in Strapi, a live address is required to redirect users after login. Ngrok is used to expose the local development server to the internet. A Facebook developer app is created to set up Facebook Login integration. The app domain option is filled with the Ngrok live URL, and the valid OAuth redirect URI is added. After setting up Strapi and Nuxt.js, a single-page application is created to interact with the Strapi backend. The login button redirects users to the Facebook authentication page, and upon successful registration, the app redirects to the home page.
