{
  "files": [],
  "types": "./index.d.ts"
}

My understanding of "files" field is "including files in the array when the package is published to npm registry.

But I don't understand what "types" do here.

From the typescript handbook:

Set the types property to point to your bundled declaration file.

This key points to the .d.ts file for the typings when you publish a typescript package.
