🌦 Weather & Air Quality Proxy Server

An Express.js server that acts as a proxy API layer for OpenWeatherMap.
It provides simplified, secure access to various weather data services including current weather, forecasts, air quality, and geocoding — while preventing CORS issues and keeping API keys safe.
