# onLogout

<Card title="Recommended: JavaScript SDK with React Hooks" icon="react" color="#4779FE">
  For new React apps, we recommend the JavaScript SDK with React Hooks (`@dynamic-labs-sdk/react-hooks`) instead of the legacy React SDK documented here. The JS SDK comes with many benefits such as a much smaller bundle size and other optimizations. Use the [React quickstart (JavaScript SDK)](/javascript/reference/react-quickstart) to get started.
</Card>

### Summary

This callback will be called after the user logs out.

It will be called either when the user explicitly logged out by calling `handleLogOut`
or when the user's token expired.

### Usage

```TypeScript theme={"system"}
<DynamicContextProvider
  settings={{
    events: {
      onLogout: (args) => {
        console.log('onLogout was called', args);
      }
    }
  }}
>
 {/* ... rest of your app ... */}
</DynamicContextProvider>
```

### Callback Argument Value

```TypeScript theme={"system"}
user: UserProfile | undefined;
```

If your auth mode is connect-only, then the user argument will be undefined, otherwise the user argument will be the user object that just logged out.

<Note>
  For details about UserProfile, see [here](/react/reference/objects/userprofile)
