# useHexclaveApp

> React hook to retrieve the HexclaveClientApp instance from the HexclaveProvider.

The `useHexclaveApp` hook returns a `HexclaveClientApp` object from the one that you provided in the setup flow. If you want to learn more about the `HexclaveClientApp` object, check out the [StackApp](/sdk/objects/hexclave-app) documentation.

## Usage

```jsx theme={null}
import { useHexclaveApp } from "@hexclave/next";  // replace `next` with the correct framework SDK package

function MyComponent() {
  const hexclaveApp = useHexclaveApp();
  return <button onClick={async () => await hexclaveApp.redirectToSignIn()}>Sign in</button>;
}
```
