Technical requirements

We use the following technologies in this chapter:

  • TypeScript playground: This is a website at that allows us to play with asynchronous code without installing anything.
  • Node.js and npm: TypeScript and React are dependent on these. We can install these from If we already have these installed, make sure npm is at least at version 5.2.
  • TypeScript: This can be installed via npm with the following command in a terminal:
npm install -g typescript
  • Visual Studio Code. We'll need an editor to write our React and TypeScript code, which can be installed from We will also need the TSLint (by egamma) and Prettier (by Estben Petersen) extensions installed within Visual Studio Code.
  • We will use this online service to help us learn...
