Interface know-how for programming. The standard work on API programming. Designing effective APIs. Developing APIs for professional projects. Application Programming Interfaces (APIs) are ubiquitous, as software developers not only use them constantly but often design them as well. This book provides a comprehensive guide to the diverse topic of API design for the first time. In addition to theoretical concepts, it offers numerous practical tips and programming examples for Java APIs. Remote APIs in the form of RESTful HTTP, GraphQL, and messaging, which are crucial for modern web applications and other distributed systems, also play a central role in this book. Contents include: Designing user-friendly APIs. Compatibility and versioning. Object collaboration, fluent APIs, and thread safety. Documentation. Scalability, caching. API management. After successfully reading this book, you will understand the fundamentals of APIs and be able to design object-oriented APIs for software components and remote APIs for distributed systems. The third edition includes new topics such as the API-first approach and security issues like authentication, API keys, Distributed Denial of Service (DDoS), and injection attacks.
