## Overview

A minimal Express web service exposes one GET / endpoint that returns a fixed greeting. The tree includes a bundled AWS CLI distribution, but no application code or documentation establishes it as part of this service’s runtime workflow, so it is omitted.

Main entry points: [`app.js`](https://github.com/ucuppristel/simple-node-app/blob/main/app.js) (Express app)
