Why Redis?

OpenWeather's free tier has rate limits. Rather than hitting the API on every request, weather data is cached in Upstash Redis and served until the TTL expires. Cuts unnecessary API calls and keeps the app fast on repeated lookups.

Setup

1. Clone the repo
2. Copy .env.example to .env and fill in your API keys:
   • OPENWEATHER_API_KEY — from openweathermap.org
   • UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN — from upstash.com
3. Install dependencies: pnpm install
4. Run dev server: pnpm dev
