Unit 2 of 7
OpenDay 2 — A real build runs
What you have afterwards: The project starts on a device or in the browser — empty, but real.
Goal
You set the project up and get it running once, all the way through.
Understand briefly
An app is more than a wrapped website. Interface and core assets belong in the local bundle, navigation has to be thumb-friendly and respect safe areas, the back gesture, the keyboard and resuming. A wrapper around a remote website saves build time today and costs you offline quality and review safety tomorrow. Also separate interface and domain logic from the start — that is the cheapest extensibility you can get.
Follow along
Paste this prompt into the AI tool you work with:
I am setting up a new app project. Target platform: [PLATFORM]. Language/framework: [YOUR CHOICE].
1. Create the project and explain every file you generate in one sentence.
2. Set up navigation with two screens that respects safe areas.
3. Split interface and domain logic into separate folders and justify the cut.
4. Give me the exact command to run the project locally.
Change nothing outside these four points.Build it yourself
Actually start the project once — on your device or in the browser. Create separate environments and, if your platform requires it, the app identifier and signing.
