ExoVault – A Cinematic NASA Exoplanet Archive Explorer

Hi again @florinpop17 and community!

I’m thrilled to showcase my second "Advanced" project completion: ExoVault, an implementation of the NASA Exoplanet Query challenge.

While the original idea focuses on querying, I decided to turn it into a high-performance Discovery Engine using a modern static-first architecture.

• Live Demo: https://johnnylemonny.github.io/ExoVault/
• GitHub Repository: https://github.com/johnnylemonny/ExoVault

🚀 Key Technical Highlights

• Architecture (Astro 6 + React 19): Used Astro's "Islands Architecture" to deliver a zero-JS baseline with interactive React components only where needed.
• Data Pipeline (1MB vs 100MB): Instead of querying the raw NASA API on every client request, I built a custom Node.js pipeline that fetches, cleans, and optimizes the NASA Planetary Systems (PS) archive into ultra-compact JSON fragments during build time.
• Side-by-Side Comparison: Implemented a complex "Comparison Vault" where users can analyze multiple exoplanetary systems across metrics like discovery method, stellar magnitude, and orbital period.
• Glassmorphic Design: A cinematic, space-themed UI featuring backdrop-blur effects and 60fps transitions that make astronomical data feel premium.
• Automated Living Archive: A weekly GitHub Action "CRON" job that pulls new NASA discoveries, rebuilds the data cache, and redeploys the site automatically.

✨ User Stories + More

• ✅ Advanced Search/Filter: Filter by discovery year, planet type, and stellar properties.
• ✅ Detailed System Views: Deep dive into individual planetary metrics.
• ✅ Responsive & Accessible: Fully mobile-optimized with WCAG 2.1 AA compliance.

🧠 Reflections

The main lesson here was performance optimization. Browsing a database of 5000+ planets can be slow; by using Static Site Generation (SSG) and pre-calculating the data, I achieved near-instant navigation that feels like a native app.

Thank you for providing the inspiration for this astronomical challenge!
