Install
% npm install -g typescript

Start a new node.js project
% npm init
% npm install typescript -s

Add "tsc" script to package.json
"scripts": {
  "tsc": "tsc"
}
% npm run tsc -- --init

Compile
% npm run tsc src/*.ts

Note: if a file/glob is specified, the tsconfig.json file is not consulted: https://www.typescriptlang.org/docs/handbook/tsconfig-json.html
Better to set the rootDir property in tsconfig.json and just run "tsc" to build all files in the project

Run the compiled script
% node script.js

Install node ts types
% npm install @types/node
