There are a lot of web development reading materials out there, from books to videos to blog posts. How can you know what is actually worth reading?
Free books. Who doesn't like free books?! But if you are able, buy the book if it is offered as an option. No worries if you can't. But if it helps the devs continue to put out quality content then it is worth it.
Books are broken down by technology/stack or concept. Feel free to add yours by opening a pull request.
Books by Flavio require a newsletter sign up but I think it is worth it.
