Part I. Introducing OpenWhisk Development
In this first part, you are going to learn how to develop OpenWhisk applications. We’ll start with the architecture of the system and the CLI. Then you will use the JavaScript API, debugging techniques, and design patterns developed specifically in JavaScript.
JavaScript is undoubtedly one of the most important and widely used programming languages available. It is also the most common language used by frontend developers, those who may need to add backend logic and don’t want to deal with the complexities of managing servers. Most people that use OpenWhisk usually start with JavaScript to keep things simple.
To hit the ground running, we’ll start by developing a simple form application. Once you know the basics, we will rewrite the application using design patterns. We’ll also cover unit testing and “mocking,” used to test software that runs in the cloud.
