Some topics to talk about

Run through / lifecycle

• A bit theoretical: What's the lifecycle of this react native app?
• How would you test the app?

TypeScript

• In the current state, the app doesn't really make use of TypeScript, or does it?
• Where, in this app, could we make (better) use of TypeScript right now?

Tasks

• Fix the app so that the map shows the area where the GeoJSON line is being drawn on startup.
• Extract the GeoJSON line to a seperate file and load it and display it once the map is rendered.
• Extend the app so that it uses tab navigation, with the app being shown in the initial tab and a second tab that shows the raw JSON of the GeoJSON line.
• Using a publically available web endpoint that serves GeoJSON, implement the loading and rendering of GeoJSON loaded over the internet.
