Feature Build-Out

Modules 1-4 built a real, working dashboard: live positions, a default watch region, free-pan, trails, and history playback. This module fills in everything else the finished app does — airports and live weather for context, the emergency-squawk and overflight detection that’s been running silently since Module 2 finally gets a UI, a place to browse the full overflight history, two watch regions side by side, quick map-view bookmarks, a shareable snapshot, and a real mobile layout.

Why This Matters

None of these six features need each other, but every one of them needs something already built. Airports and alerts both extend the store and the header icon row Module 3 deliberately left room for. The overflight log finally gives Module 2’s silent detection engine somewhere to show its work. Multi-region compare is close to free, because Module 4 already stores positions per region instead of in one flat list. None of this is new architecture — it’s the payoff for architecture decisions made two and three modules ago.

What You’ll Learn

• Seeding and querying a real airport dataset by map viewport, plus a live METAR weather overlay
• Consuming the WebSocket’s two remaining message types to build a live alert feed with sound and browser notifications
• Configuring a home location and browsing the full, persisted overflight log
• Rendering two watch regions side by side, and a lightweight saved-locations bookmark feature distinct from watch regions
• Capturing a shareable snapshot of the current view and filling in the mobile layout

Outcome

By the end of this module, SKYWATCH has every feature the real, finished app has. Module 6 closes the course out with testing, verification, and where to take the project next.
