I’m thrilled to announce that I’m writing a book about API design: The Design of Everyday APIs (edit: the book has been renamed The Design of Web APIs since this post has been written). This book is published by Manning Publications and the first two chapters are now available on the Manning Early Access Program. This book is for everyone who wants to learn API design. But, what’s the story behind this book about API design? To answer this question, let’s talk about my other passion: guitar.

Join Frodo, Gollum and Gandalf on an epic API design adventure. In this session, based on my own experience defining and sharing API design common practices in my company and based on the API styles guides that I have collected on apistylebook.com, we will discover why we desperately need API style guides and how they can or cannot help us create a smooth API surface for a company.

I’ve added the Deliveroo API Design Guidelines to the API Stylebook. These guidelines are definitely a MUST read for any API designer. To discover this API design guide and a short review, let’s go to the API Stylebook blog.

Getting, creating, updating or deleting multiple resources in a single API call is a common need in REST APIs. But how to achieve that in a consistent way accomodating how we work with a single resource and REST principles? This is what we’ll see in this post.

The OpenAPI Visual Documentation has been updated. The new version 3.0.0-rc0 of the OpenAPI specification has been added. The addition brings a fully detailed change log of what has change from version 2.

I’ve just added the Google API Design Guide to the API Stylebook. This guide is slightly different from the other ones because it deals with REST and RPC API design focusing on gRPC APIs using Protocol Buffers v3. To discover this API design guide and a short review, let’s go to the API Stylebook blog.

This is the end, my OpenAPI friends, the end. The end? Not really. This last part of the OpenAPI tutorial is a new beginning. With previous parts we have learned to master the OpenAPI specification but there’s a last thing to learn to unleash its full power: extensions. This format is easily extensible, it allows to add custom data within an API description. But for what purposes? Let’s have a glimpse of these extensions endless possibilities.

GraphQL is new. GraphQL is cool. Look! Github dumped REST for it! We MUST do it too!
Well, why not. GraphQL could be a great tool, but like any tool, you don’t choose it just because. You choose it because it solves a problem in a given context. You choose it knowing its strengths and weaknesses.

ICYMI, I’ve just switched from a self hosted Wordpress to a Jekyll static website hosted on Github. The code is available in the apihandyman.io repository. If you’re looking for information and tips about how to enable pagination on categories pages and have infinite scroll with Jekyll or how to to deploy a Jekyll website using custom plugins on Github Pages, you should take a look at it.

GraphQL is new. GraphQL is cool. Look! Github dumped REST for it! We MUST do it too! Well, why not. GraphQL could be a great tool, but like any tool, you don't choose it "just because".You choose it because it solves a problem in a given context. You choose it knowing its strengths and weaknesses. During this session, while discovering what is GraphQL we will see what REST API providers should think about before blindly dumping REST for it
