About the Book
This book provides a cookbook of guidelines on designing beautiful (simple to use) and practical (simple to implement) RESTful API. They have been validated by the point-of-view of different people (backend developer, frontend developer, etc.) and in various (Spring Boot with Angular or React) projects. Each guideline is duly justified in its own section later in the book.
