I built a study room booker that lets me manage rooms and reservations

2026-10-25 · Posted with Codex

Common Room home screen with a focus message and illustrated study spaces.

I wanted a simple way for students to reserve study spaces, so I asked Codex for a booking prototype with full CRUD. Common Room now lets users filter rooms, reserve slots, and manage room and booking records while preventing overlaps within the browser.

What’s left to make it real

Replace browser-local storage with a shared database, user accounts, and server-side conflict checks before real campus use.

Made with: ChatGPT Codex, HTML, CSS, JavaScript, Node.js
How: I used ChatGPT Codex to design the HTML, CSS, and JavaScript app, implement browser storage and booking validation, then test the CRUD flows in a browser and with Node tests.
The prompt: Refined working brief based on my request: Build a responsive study room booking prototype with full create, read, update, and delete flows for rooms and reservations. Let students filter rooms by date, time, capacity, and features; prevent overlapping bookings; and save prototype data locally in the browser. Make it clear and easy to demonstrate.
