  • Express: Web framework for Node.js

Source code: d-dmytro/my-typescript-app

mkdir my-typescript-app
cd my-typescript-app

Run npm init to create the package.json file in this folder. I’ve chosen defaults for the options.

Let’s install TypeScript and the types for Node.js as dev dependencies.

npm i -D typescript @types/node@12

I installed the types for Node.js 12 because that’s the version I’m using in this project. …
