## Overview

This is a small Express web application: a browser requests the home page or health endpoint, and the server serves the HTML or returns health data. Both routes and the static-file middleware are defined in `src/main.js`; the home page is `src/pages/home.html`. The README documents development and production Docker configurations, but those are deployment modes rather than runtime product subsystems, so they are omitted here.

Main entry points: [`src/main.js`](https://github.com/dinesheth/docker-node-app/blob/main/src/main.js) (Express server), [`src/pages/home.html`](https://github.com/dinesheth/docker-node-app/blob/main/src/pages/home.html) (Home page)
