Components

In the last guide, we initialized Stack. This time, we will take a quick look at some of the most useful Next.js components.

For the full documentation of all available components, please refer to the components reference.

<UserButton />

The <UserButton /> component shows the user’s avatar and opens a dropdown with various user settings.

1
import { UserButton } from '@stackframe/stack';
2
3
export default function Page() {
4
  return (
5
    <UserButton />
6
  );
7
}

<SignIn /> and <SignUp />

These components show a sign-in and sign-up form, respectively.

1
import { SignIn } from '@stackframe/stack';
2
3
export default function Page() {
4
  return (
5
    <SignIn />
6
  );
7
}

All of Stack’s components are modular and built from smaller primitives. For example, the <SignIn /> component is composed of the following:

• An <OAuthButtonGroup />, which itself is composed of multiple <OAuthButton /> components
• A <MagicLinkSignIn />, which has a text field and calls useStackApp().signInWithMagicLink()
• A <CredentialSignIn />, which has two text fields and calls useStackApp().signInWithCredential()

You can use these components individually to build a custom sign-in component.

To change the default sign-in URL to your own, see the documentation on custom pages.

Others

Stack has many more components available. For a comprehensive list, please check the documentation on components.

In the next guide, we will do a deep-dive into retrieving and modifying user objects, as well as how to protect a page.
