Implementation guide
Prevent duplicate form submissions in React
Add a reusable React submit guard that disables repeat sends while a request is pending and gives people a clear retry path.
The mistake this stops
The same form or payment is sent twice while the first request is still pending.
One deliberate submission, a visible pending state, and a form that remains recoverable if the request fails.
Read the Safe Submit component docs for its live preview, API, accessibility notes, dependencies, and limitations.
Install the component
Use it safely
- Install the component into your shadcn project.
- Pass the async save or payment handler you already use.
- Keep idempotency and authorization checks on the server; the UI prevents accidental repeats, not malicious requests.
