## Overview

This Angular application presents weather for several countries and a selectable country forecast. The runtime starts at the Angular bootstrap, routes to the weather layout, fetches current conditions and forecast data from OpenWeather, and transforms the responses for display. Separate controls provide language selection and dark-mode toggling, with localized date formatting and translation catalogs. The README contains no product feature detail; several UI templates and translation-loading behavior were not excerpted, so those connections are not inferred.

Main entry points: [`src/app/app.module.ts`](https://github.com/haroon786/angular-europe-weather/blob/master/src/app/app.module.ts) (App module), [`src/app/openweather.service.ts`](https://github.com/haroon786/angular-europe-weather/blob/master/src/app/openweather.service.ts) (Weather service), [`src/app/app-routing.module.ts`](https://github.com/haroon786/angular-europe-weather/blob/master/src/app/app-routing.module.ts) (Root routing), [`src/app/weather-layout/weather-layout.component.ts`](https://github.com/haroon786/angular-europe-weather/blob/master/src/app/weather-layout/weather-layout.component.ts) (Weather layout)
