A first-time app builder shipped a live closet inventory app during class
A simple closet inventory app, built in class, now live on the web with a real database, reports and CSV export.
This student came to class new to app creation and left with a working app on the internet. They wanted something modest, a way to list what is in their closet, and they saw it all the way through to a live, tested product. Then they turned the messy journey into a guide for next time, which is exactly the kind of habit that makes a beginner a builder.
Closet Inventory
Before
They had a simple wish: an app to list the items in their closet, with quantity and use, and a report of what is in there. They called themselves new to app creation. Tools like Vercel, GitHub and Neon Postgres were not things they knew much about, and Node.js was not even installed on their machine.
“(not too fancy since I was doing during the class.”
In their own words
The turning point
During the class they worked with Claude Cowork through five stages: spec, build, test locally, ship to GitHub, deploy. They hit real bumps along the way, from a missing git identity to SQLite not surviving on Vercel and quirks with database secrets. Each one got solved, and each one taught them something about how apps actually reach the web.
After
Their app is now live on Vercel, redeploying automatically every time they push changes. Their data lives in a Postgres database, so it persists across visits, and local work and the live site share the same data. Adding, editing, deleting, filtering, the summary report and CSV export were all tested end to end. They also asked for a written summary of the whole flow, so they have a map to follow next time.
What it lets people do
The app lets someone keep a clear record of what is in their closet, how many of each item they have and what it is used for. They can filter the list, see a summary report and export everything to a spreadsheet.
What they learned
They learned that the big picture matters as much as the code: knowing the stages from spec to deploy helps you start better. Instead of leaving the bumps behind, they captured them in plain language, with a checklist and glossary, so the next app starts from experience rather than from scratch.
“I am new to app creation and want to have a big picture of what I need to do better from the beginning.”
