In this chapter, we have talked about starting from scratch with TypeScript by passing through the installation and configuration of Node.js. We also presented the Express.js server using Node.js and our first hello world application. To get all of the necessary tools installed, we talked about npm and how powerful this tool is during the development process.
After we installed Node.js, we walked through TypeScript's installation and preparing the development environment by using VS Code and the basics of TypeScript, such as configuring Linters to help us with patterns and formatting your coding environment for better coding.
The last part of this chapter covered testing tools, different types of tests, how to set up and debug using VS Code, and how to define build tasks for transpiling TypeScript code and building the application.
The next chapter will walk you through...
