I'd highly recommend reading some articles by Luca Palmieri[1], or even buying his book[2]. Although I didn't learn this stack by working through his book, whenever I had questions through the years, my searches usually led me to his articles which are often excerpts from the larger book.
The high level of API stability and lack of churn in the Actix ecosystem makes the book a particularly good investment for someone looking to settle on this stack in my opinion. In keeping with the topic of this submission, I doubt I'd be comfortable spending money on a similar book about building web apps with React.
