Tennis Club Reservation System: Court booking with weather forecasts for tennis clubs

Hey Product Hunt! 👋 Creator here - excited to share what I've built! **The Story**: My local tennis club was managing court bookings with Excel spreadsheets. Coaches would text each other about availability. Members had no idea about weather until they showed up. It was chaos! So I built this over the past 3 months. **What Makes It Different**: Most booking systems don't integrate weather. I added OpenWeather API so members can see forecasts before booking. Also designed it to be senior-friendly (large fonts, high contrast) since most tennis club members are 50+. **Tech Highlights**: • Angular 20 with standalone components (no NgModules!) • Socket.io for real-time chat • MongoDB with compound indexes for preventing double-bookings • JWT auth with 3-tier role system • PWA with offline support **What You Get**: Full source code - own it forever. No monthly SaaS fees. Deploy to your own server. Customize however you want. **I'd Love Your Feedback On**: 1. Is $79 fair for full source code? 2. What features would you add? 3. Which sports could this work for? (badminton, squash, etc?) Happy to answer any questions about the architecture, tech stack, or implementation! Thanks for checking it out! 🎾
