Greetings. Each of us in this wonderful year finds his own way to pass the time. For example, I am writing a book. A book about what I know and love - about the API. (Who I am and what experience I have in development can be found here )
→ So far I have written the first part - about the principles of API design "from top to bottom"
→ PDF version can be downloaded from here
Questions, wishes and suggestions are accepted. The book is distributed free of charge under CC-BY-NC terms. You're welcome!
