FAQ
- How do I add Promo Code with Cursor or Claude Code?
- Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
- What does Promo Code depend on?
- No npm packages beyond React and Tailwind CSS.
- What can I change in Promo Code?
- Adapt: the label copy and the codes dictionary; the wording of the error and success messages; the onApply handler — replace the demo delay with a request. Keep as installed: the local --vibeui-input-013-* palette — do not swap it for your theme tokens; the three separate states: an applied code is not an input, it cannot be edited; the form wrapper: Enter must apply the code without any key handlers.
- Is Promo Code free?
- Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.
For developers
npx shadcn@latest add https://vibeui.club/r/pro/input-013.jsonThis command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options
Technical notes
The component is self-contained: one file, no dependencies, its own palette in local variables --vibeui-input-013-*. A client component: "use client". The three states have different markup: a form with a field and a button, the same form with the button disabled while the check runs, and a chip with the applied code and a "Remove" button. The wrapper is a real <form>, so Enter submits without any key handlers. The input is uppercased in state, not only in CSS.
