Deadline Warning

A deadline field that says out loud the date has passed: browsers treat a past date as valid and stay silent.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • label — the field caption
  • defaultValue — the starting deadline
  • soonInDays — how many days ahead counts as due soon

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Deadline Warning 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 Deadline Warning depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Deadline Warning?
Adapt: label — the field caption; defaultValue — the starting deadline; soonInDays — how many days ahead counts as due soon. Keep as installed: the local --vibeui-date-006-* palette — do not swap it for your theme tokens; the transparent background by default — the component sits on the page background instead of laying a panel under itself; reading today through useSyncExternalStore with an empty server snapshot: computing it during render makes server and client disagree at hydration.
Is Deadline Warning 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/date-006.json

This 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, zero dependencies, palette in the local --vibeui-date-006-* variables. Client component: the date is in state, while today is read through useSyncExternalStore — the server snapshot is empty, so there is nothing to compare and hydration does not disagree; computing "today" during render means getting different dates on the server and on the client. There are three states: overdue, due soon, time left; they are marked with data-state on the root and override a single accent variable, so the colour of the border, the stripe and the text changes at once. Before the first client snapshot the state is neutral.
