Typescript

This library is written using typescript and exports all of the relevant typings you might need.

Using typescript along with usePrompt is pretty straightforward, here is an example:

import usePrompt, { RenderProps } from "use-prompt";

function Prompt({ resolve, reject, visible }: RenderProps) {
  return visible ? (
    <div>
      <div>Are you sure?</div>
      <div>
        <button onClick={resolve}>Resolve</button>
        <button onClick={reject}>Reject</button>
      </div>
    </div>
  ) : null;
}

function App() {
  const [prompt, setPrompt, visible] = usePrompt({ persist: true });

  function showPrompt() {
    setPrompt((props) => <Prompt {...props} />);
  }

  return (
    <div>
      <button onClick={showPrompt} disabled={visible}>
        Show prompt
      </button>
      {prompt}
    </div>
  );
}

The only real difference here (compared to plain JS) is the incorporation of the RenderProps type in the Prompt component.

This is the interface which defines the (resolve, reject, and visible) properties passed into the function. You can of course extend this and add your own props as you like:

interface PromptProps extends RenderProps {
  someProp: boolean;
}

function Prompt(props: PromptProps) {
  /* ... */
}
