I recently came across the concept of "headless" WordPress and found a useful resource in the form of a headless WordPress guide  https://getdevdone.com/blog/headless-wordpress-guide-insights.html on this website. This guide was a real eye-opener for me, as it explains in detail how to use WordPress as a backend without being tied to a standard frontend. In this material, I learned about the benefits of this approach, including the ability to create high-performance and flexible web applications. What I especially liked was that the guide contains specific examples and practical tips on integrating WordPress with various frontend technologies. It also emphasizes the importance of using REST APIs and GraphQL for communication between the frontend and backend. Thanks to this guide, I was able to better understand how existing projects can be modernized and improve their performance.
