The goal of this chapter was to introduce a basic workflow that could be used by the reader to implement the design patterns we'll be discussing.

We talked about the installation of TypeScript compiler that runs on Node.js, and had brief introductions to popular TypeScript editors and IDEs. Later, we spent quite a lot of pages walking through the tools and frameworks that could be used if the reader wants to have some practice with implementations of the patterns in this book.

With the help of these tools and frameworks, we've built a minimum workflow that includes creating, building, and testing a project. And talking about workflows, you must have noticed that they slightly differ among applications for different runtimes.

In the next chapter, we'll talk about what may go wrong and mess up the entire project when its complexity keeps growing. And we'll try to come up with specific patterns that can solve the problems this very project faces.
