Guides
Build safer React forms and actions
Start with the problem you are implementing. Each guide points to a working component, explains the boundary between client guidance and server enforcement, and ends with the exact install command.
- Prevent duplicate form submissions in ReactAdd a reusable React submit guard that disables repeat sends while a request is pending and gives people a clear retry path.
- Validate a shadcn email input in ReactCatch incomplete and typo-prone email addresses with a copy-paste React field that fits shadcn styling and keeps the user’s value intact.
- Confirm a dangerous delete action in ReactReplace a vague “Are you sure?” dialog with a typed confirmation that makes the target and consequence explicit before deletion.
- Validate a UPI ID input in ReactHelp people enter a well-formed UPI ID without incorrectly rejecting an unfamiliar but valid VPA in an offline client-side form.
- Add React field validation without changing your UI libraryUse a headless field hook with shadcn/ui, HeroUI, or a custom control while retaining your existing markup, styles, and accessibility decisions.
