## Overview

This is a browser-based weather app: a user enters a ZIP code, the client fetches current weather and location coordinates, then requests supplemental forecast-region and local-time data. It posts these results to an Express server, which keeps them in memory and serves them back for display. The source shows these workflows and routes; the README is empty, and generated distribution files were not treated as runtime source.

Main entry points: [`src/client/js/app.js`](https://github.com/dmclayto/danielsweatherapp/blob/main/src/client/js/app.js) (Weather workflow), [`src/server/server.js`](https://github.com/dmclayto/danielsweatherapp/blob/main/src/server/server.js) (HTTP server), [`src/client/views/index.html`](https://github.com/dmclayto/danielsweatherapp/blob/main/src/client/views/index.html) (Weather page), [`src/client/index.js`](https://github.com/dmclayto/danielsweatherapp/blob/main/src/client/index.js) (Client entry)
