API Design for C++ Martin Ry
Publisher: Morgan Kaufmann

After reviewing hundreds of actual SaaS APIs, many up to par and others distinctly . However, designing reusable C++ interfaces that are robust, stable, easy to use, and durable is even more difficult. The design of application programming interfaces can affect the behavior, capabilities, stability, and ease of use of end-user applications. Http://www.apibook.com/blog/archives/95 API Design for C++. In the last couple of weeks I learned two important lessons about API design not by practicing my craft, but from listening to our users. Think of it as Node.js, but using C. What I learned may appear as common sense by most of you. Even though I live in the C++ world as opposed to Java, 99% of this is directly applicable. The best way to succeed in this endeavor is to adhere to the tenets of good Application Programming Interface (API) design. There are many different rules and tradeoffs to consider during Java API design. Like any complex task, it tests the limits of our attention and memory. As a result, APIs are not well designed or properly built and wind up costing both the vendor and its customers tens of thousands of dollars in ongoing maintenance due to infrastructure costs and the drain on engineering resources. Somewhat later I had the pleasant experience of writing C++ code with Qt. AZR331 Casablanca is a Microsoft incubation effort to support cloud-based client-server communication in native code using a modern asynchronous C++ API design. Based on hearsay, Qt is quite complicated and hackish inside, but what it presents to the outside is pure delight in terms of API design. Some good advice comes from the developers behind Qt who have corrected some things in their API and described it at: Designing Qt-Style C++ APIs. The task of designing a web service or API that adheres to the REST guidelines then becomes an exercise in identifying the resources that will be exposed and how they will be affected by the different request methods. Similar to the pilots' pre-flight checklist, this list helps software designers remember obvious and not so obvious rules while designing Java APIs.
