Technical requirements

In order to complete this chapter, you are going to need Node.js installed. You can download and install Node.js from https://nodejs.org/en/.

You will also need the TypeScript compiler installed. There are two ways to do this through Node.js using the Node Package Manager (NPM). If you want the same version of TypeScript used in all of your applications and are happy that they will all run on the same version whenever you update it, use the following command:

npm install -g typescript

If you want the version of TypeScript to be local to a particular project, type the following in the project folder:

npm install typescript --save-dev

For a code editor, you can use any suitable editor or even a basic text editor. Throughout this book, I will be using Visual Studio Code, a free cross-platform integrated development environment (IDE), available at https://code.visualstudio.com/. 

All code is available on GitHub at https://github.com/PacktPublishing/Advanced-TypeScript-3-Programming-Projects/tree/master/Chapter01.
