TypeScript

The only time I use interfaces is to expose types publicly so that the consumer of your code can extend the types if needed, or when implementing with a class.
While object implementing some interface can have more properties than the interface defines, types limit the shape to exactly what type has defined.

npm script

It's actually better to use tsconfig.json.

"scripts": {
  "start": "./node_modules/nodemon/bin/nodemon.js -e ts  \
    --exec \"npm run compile\"",
  "compile": "tsc --outDir ./build --module commonjs ./src/*.ts && \
    node ./build/server.js"
}
