Weather App

A simple React application to fetch and display weather data using the OpenWeatherMap API. Built with TypeScript, Chakra UI, and Axios, with unit tests using Jest and React Testing Library.

Features

• Search for weather by city name.
• Displays temperature, weather description, and last updated time.
• Caches weather data in localStorage for 5 minutes.
• Responsive design with Chakra UI.
• Unit tests for components and hooks (10/11 passing).

Installation

1. Clone the repository: git clone https://github.com/maxsabo/weather-app
2. Install dependencies: npm install
3. Create a .env file in the root directory and add your OpenWeatherMap API key: VITE_API_KEY=your-api-key-here
4. Start the development server: npm run dev

Testing

Run unit tests with: npm test

Note: One test ("handles error when city not found" in useWeather.test.tsx) is commented out due to issues with mocking AxiosError in Jest. The functionality works in the app but couldn't be reliably tested.
