Read ‘The API’ Book by Sergey Konstantinov in English

Читать книгу ‘The API’ Сергея Константинова по-русски

This is the working repository for ‘The API’ book written by Sergey Konstantinov (email, Linkedin profile, Medium blog).

API-first development is one of the hottest technical topics nowadays since many companies started to realize that API serves as a multiplicator to their opportunities—but it also amplifies the design mistakes as well.

This book is written to share the expertise and describe the best practices in designing and developing APIs. It comprises six sections dedicated to:

• the API design
• API patterns
• backwards compatibility
• HTTP API & REST
• SDK and UI libraries
• API product management.

Current State and the Roadmap

Right now three sections (‘The API Design’, ‘The Backwards Compatibility’, and ‘The API Product’) are finished, comprising the first edition of the book. Three other sections are drafted and are now being added to the clean copy chapter after chapter.

Also, the book still lacks readable schemes which I'm still planning to plot with mermaid.
