## Overview

This is a small Electron desktop application for accessing the PC webcam. On Electron startup, its TypeScript entry point creates a window and loads the page; the page’s JavaScript requests video-only media, attaches the returned stream to a video element, and plays it. If access fails, the script logs the error and alerts the user. The HTML and CSS were not sampled, so page wiring and presentation details are not inferred.

Main entry points: [`pages/js/script.js`](https://github.com/patrickrhamon/webcam-electron/blob/main/pages/js/script.js) (Camera capture), [`src/index.ts`](https://github.com/patrickrhamon/webcam-electron/blob/main/src/index.ts) (App window), [`pages/index.html`](https://github.com/patrickrhamon/webcam-electron/blob/main/pages/index.html) (Application page)
