Booking flow

Preview of OnyxStudio

Description

Built for anyone who wants a booking flow and none of the setup that usually comes with one. OnyxStudio leans brutalist — plenty of room, very little chrome — and everything on screen is something you can act on.

  • Responsive down to a phone without a separate layout
  • Every action is undoable
  • Shareable state — the URL is the document

Cursor and Astro did most of the lifting. I wrote the schema by hand and let the generated components follow it rather than the other way round.

If you build on it, the interesting file is the one that maps the query to the view — everything else is presentation.

Workflow

  1. Generated the first pass in Cursor

    Iterated on the prompt rather than on the output — fixing the generated code by hand meant losing the fix on the next regeneration.
