Makerkit provides a set of React hooks to help you manage authentication in your React application. These hooks are an addition to the ones provided by `reactfire`.

## useUserSession

This hook returns the current user session. It contains the user's auth data from Firebase, and its data record from Firestore. Basically, it wraps the `UserSessionContext` value.

```tsx
import { useUserSession } from "~/core/hooks/use-user-session";

const userSession = useUserSession();
```

## useUserId

This hook returns the current user's ID.

```tsx
import { useUserId } from "~/core/hooks/use-user-id";

const userId = useUserId();
```

## useCreateServerSideSession

This hook returns a function that can be used to create a server-side session. It is useful for creating a session when a user logs in, or when a user is created.

You shouldn't be needing this unless you're customizing the authentication flow.

```tsx
import { useCreateServerSideSession } from "~/core/hooks/use-create-server-side-session";

const [sessionRequest, { loading, error }] = useCreateServerSideSession();
```
