Designing APIs with Swagger and Openapi - by Joshua S Ponelat & Lukas L Rosenstock (Paperback)

About the Book

Customer-facing and internal APIs have become the most common wayto integrate the components of web-based software. Using standards like OpenAPI, you can provide reliable, easy-to-use interfaces that allow other developers safe, controlled access to your software. Designing APIs with Swagger and OpenAPI is a hands-on primer to properly designing and describing your APIs using the most widely-adopted standard.

Book Synopsis

Follow real-world API projects from concept to production, and learn hands-on how to describe and design APIs using OpenAPI.

In Designing APIs with Swagger and OpenAPI you will learn how to:

Understand OpenAPI syntax and structure
Use Swagger and other tooling to create OpenAPI definitions
Design authentication and authorization
Turn an OpenAPI description into online documentation
Automate processes and generating code
Iterate an API design with user stories
Build a frontend against a mock server
Generate backend code with Swagger Codegen
Versioning an API and dodging breaking changes
Work with cross-functional teams

Designing APIs with Swagger and OpenAPI is a comprehensive guide to designing and describing your first RESTful API using the most widely adopted standards. Following expert instruction from Swagger core contributor Josh Ponelat and API consultant Lukas Rosenstock, you'll spend each chapter progressively expanding the kind of APIs you'll want to build in the real world. You'll utilize OpenAPI and Swagger to help automate your workflow, and free up your time to work on more exciting features. Learn the syntax and structure of OpenAPI definitions, create and iterate on an API design with common tools, and release your API to the public.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the technology
Create web APIs that customers and developers will love! Using Swagger, a collection of tools for defining and documenting REST APIs, you will build safe, controlled access to your software. And because Swagger implements the vendor-neutral OpenAPI specification, you'll be building to the same standards adopted by Google, Microsoft, and Amazon.

About the book
Designing APIs with Swagger and OpenAPI introduces a design-first approach. Written for developers new to API design, it follows the lifecycle of an API project from concept to production. You'll explore the dos and don'ts of APIs through progressively complete examples. You'll get hands-on experience designing APIs for specific business needs, using open source tools to generate documentation, and building developer-friendly components like mocks and client SDKs.

From the Back Cover

Designing APIs with Swagger and OpenAPI is a hands-on primer for describing, planning and designing web APIs. Core Swagger contributor Josh Ponelat introduces you to a design-first paradigm that will teach you the best practices for describing and designing RESTful APIsusing OpenAPI and Swagger. You'll build upon progressively-enhanced examples asyou learn to describe an API and then extend it in the kind of scenarios you'dencounter in the real world. You'll practice skills for assessing business needs, gathering requirements, and working with a cross-functional team. And as you go, you'll use the popular Open Source tools to define APIs, generate documentation, and build other developer-friendly components like mocks, serverstubs, and client SDKs.
