Strapi is a headless CMS that utilizes Node.js and React.js for its development, offering a unique plugin design pattern and a flat learning curve. It has gained popularity due to its flexibility in integrating with various JavaScript front-end frameworks such as Nuxt.js, Vue.js, React.js, Next.js, among others. Strapi can be used with core HTML, CSS, and Vanilla JavaScript or jQuery. The platform comes pre-equipped with rich APIs that cater to most Jamstack needs. To implement Facebook authentication in Strapi, developers need a Facebook developer app to redirect users after successful login. Ngrok is used as a tool to expose the local development server to the internet for simplicity. Once set up, Strapi integrates seamlessly with Nuxt.js applications to provide social media authentication capabilities. The integration process involves creating a new Strapi project, installing Ngrok, setting up the Facebook developer app, and configuring the Strapi dashboard to redirect users after successful login.
