## Overview

This is a Spring-based weather lookup app with a browser UI: users search by city and see current conditions and related measurements. The browser code requests `/api/weather` and renders the returned data; the tree identifies corresponding controller, service, and response-model modules. Backend source and README content were not available to verify controller-to-service calls or any weather-data provider, so those links are omitted.

Main entry points: [`app/src/main/resources/static/script.js`](https://github.com/whizz76/weatherapp/blob/main/app/src/main/resources/static/script.js) (Weather UI), [`app/src/main/resources/static/index.html`](https://github.com/whizz76/weatherapp/blob/main/app/src/main/resources/static/index.html) (Weather page), [`app/src/main/java/com/example/WeatherApp/controller/WeatherController.java`](https://github.com/whizz76/weatherapp/blob/main/app/src/main/java/com/example/WeatherApp/controller/WeatherController.java) (Weather controller)
