API Developer Weekly

Jan 30, 2020 - Issue #293
This week's articles focus on an introduction to AsyncAPI for capturing messaging descriptions (think OpenAPI Specification for messages and streaming APIs), along with a call for help to assist in defining the formats for 13 separate AsyncAPI protocol bindings. This is a great initiative and I highly encourage you to check it out, give it a try, and perhaps consider giving a bit of time to grow the specification.

Also included this week are tips for testing APIs from me, and some additional articles around building APIs (this time using R) and more on deciding between monolith vs. microservice architecture by considering architectural drivers (hint: it isn't all about tech).

Happy reading! -- James

AsyncAPI: 2020's Industry Standard For Messaging APIs?
The industry is made up of a wide variety of implementations, solutions, and frameworks. Within this cloud of competing systems, the messaging API fights for a very specific, often niche section of development efforts. The quest to find a strong standard for these types of APIs, then, is a continuing effort. by Kristopher Sandoval []

Help Defining 13 of the AsyncAPI Protocol Bindings

Tips for Testing Your API
When building an API, a good test strategy ensures that your API both works correctly and meets the promises of its definition.

Google Sheets API V3 Deprecation Highlights Importance of Dev Alignment With API Roadmaps
​Google announced in September of 2019 that they plan on ending support for V3 of the Google Sheets API, a decision that has drawn the ire of some developers. Version 4 of the API was announced at Google I/O 2016, almost 4 years before the seemingly inevitable deprecation of its predecessor. []

Modular Monolithic Architecture, Microservices and Architectural Drivers
Kamil Grzybek thinks that too often we implement a microservices architecture because we believe it will solve all problems in a monolithic application. Instead, we should focus on architectural drivers to find the best architecture for a system. []

Book: A Practical Approach to API Design by Casey and Higginbotham
If you read the tech press, everyone knows they need an API but most aren't really sure what it is. They treat it as another checkbox like "Web 2.0" was a few years ago or a mobile app was most recently. In fact, there’s an entire “API-first” movement in development circles that most people don’t understand or even realize why. In this book, we'll start by discussing the what an API is, why you might need one, and follow up with the how to build one. []
