Continuous Integration, Delivery, and Deployment

By: Sander Rossel

Overview of this book

The challenge faced by many teams while implementing Continuous Deployment is that it requires the use of many tools and processes that all work together. Learning and implementing all these tools (correctly) takes a lot of time and effort, leading people to wonder whether it's really worth it. This book sets up a project to show you the different steps, processes, and tools in Continuous Deployment and the actual problems they solve. We start by introducing Continuous Integration (CI), deployment, and delivery as well as providing an overview of the tools used in CI. You'll then create a web app and see how Git can be used in a CI environment. Moving on, you'll explore unit testing using Jasmine and browser testing using Karma and Selenium for your app. You'll also find out how to automate tasks using Gulp and Jenkins. Next, you'll get acquainted with database integration for different platforms, such as MongoDB and PostgreSQL. Finally, you'll set up different Jenkins jobs to integrate with Node.js and C# projects, and Jenkins pipelines to make branching easier. By the end of the book, you'll have implemented Continuous Delivery and deployment from scratch.

Creating a Simple JavaScript App

In this chapter, we are going to create a simple web shop. We will start by writing a frontend using HTML, CSS, and JavaScript. Notice the lack of a backend. What I really like about frontend development is that it is so easy to get started with. We can create a complete app using only Notepad(++) or any other text editor. Of course, the lack of a database will prevent us from storing our results, but for now, that does not matter. The focus of this book is CI, not databases or backend development. The frontend alone will be enough to explore CI. After all, we can do tests and other automated tasks, such as minification. Even Continuous Delivery and Deployment are possible to implement (just copy your files to some server hosting your website), but we will delay that until we have our backend as well. What is really cool though is that we will...
