Simple full-stack weather app (Node + Express backend, static frontend) that lets users get current weather for any city.

• Search weather by city name
• Backend proxies requests to OpenWeatherMap (keeps API key secret)
• Small, easy-to-read codebase ready to upload to GitHub

1. Clone or copy files to a folder.
2. Create a file named .env in the project root with:

   OPENWEATHER_API_KEY=your_openweathermap_api_key_here
   

3. Install dependencies:

   npm install
   

4. Start the server:

   npm start
   

5. Open http://localhost:3000 in your browser.

• This can be deployed to services like Render, Heroku, Railway, Vercel (serverless), etc.
• Make sure to set the OPENWEATHER_API_KEY environment variable in your hosting provider.

• The app queries OpenWeatherMap Current Weather API (/data/2.5/weather) and returns metric units.
• You can modify public/app.js to change UI or show more fields.
