## Overview

Weather App is a React dashboard whose main workflow starts with a city search, updates app-level weather state, and presents current conditions, a two-day hourly chart, and a 14-day daily forecast. Separate data paths use WeatherAPI for current conditions and chart data, and Open-Meteo for geocoding and daily forecasts. The README also documents localized UI, weather highlights, and dynamic backgrounds. The tree and sampled source support the main component wiring; WeatherApi and some peripheral components were not sampled, so their internal behavior is not expanded.

Main entry points: [`src/App.js`](https://github.com/pavloshaparenko/react-weather-app/blob/main/src/App.js) (App State), [`src/widgets/UpWeatherPc.js`](https://github.com/pavloshaparenko/react-weather-app/blob/main/src/widgets/UpWeatherPc.js) (Daily Forecast Loader), [`src/widgets/WeatherManager.js`](https://github.com/pavloshaparenko/react-weather-app/blob/main/src/widgets/WeatherManager.js) (Hourly Data Manager), [`src/widgets/header.js`](https://github.com/pavloshaparenko/react-weather-app/blob/main/src/widgets/header.js) (Search & Language)
