import { ConfirmDialog }from "@/components/ui"
Specification
Modal confirmation for consequential actions, supporting simple, type-to-confirm and press-and-hold modes.
Props (11)
Every prop this component accepts, its type, default, and how to use it.
| Prop | Type | Default | Description |
|---|---|---|---|
| open* | boolean | — | Controls whether the dialog is rendered. |
| tone | "default" | "destructive" | "default" | Sets the visual emphasis; destructive uses error styling for dangerous actions. |
| title* | string | — | Heading question shown at the top of the dialog. |
| body | string | — | Optional supporting text explaining the action. |
| consequences | string[] | [] | Bulleted list of side effects shown to the user. |
| confirmLabel* | string | — | Label for the confirm button. |
| mode | "simple" | "type" | "hold" | "simple" | Confirmation strategy: a plain button, type-to-match, or press-and-hold. |
| typeToMatch | string | — | The exact string the user must type when mode is "type". |
| onConfirm* | () => void | — | Called when the user confirms the action. |
| onCancel* | () => void | — | Called when the user cancels or dismisses the dialog. |
| loading | boolean | — | Shows a pending state on the confirm button while the action runs. |
