<SignUp /> component

Sign up component example

The <SignUp /> component renders a UI for signing up users. The functionality of the <SignUp /> component is controlled by the instance settings you specify in your Clerk Dashboard(opens in a new tab), such as sign-in and sign-up options and social connections. You can further customize your <SignUp /> component by passing additional properties at the time of rendering.

Properties

All props are optional.

NameTypeDescription
appearanceAppearance | undefinedOptional object to style your components. Will only affect Clerk Components and not Account Portal pages.
routing'hash' | 'path' | 'virtual'The routing strategy for your pages.
Note: If you are using environment variables for Next.js or Remix to specify your routes, this will be set to path.
pathstringThe path where the component is mounted on when path-based routing is used
For example, /sign-up
This prop is ignored in hash- and virtual-based routing.
redirectUrlstringFull URL or path to navigate to after successful sign in or sign up.
The same as setting afterSignInUrl and afterSignUpUrl to the same value.
afterSignInUrlstringThe full URL or path to navigate to after a successful sign in. Defaults to /. It's recommended to use the environment variable instead.
signInUrlstringFull URL or path to the sign in page. Use this property to provide the target of the 'Sign In' link that's rendered. It's recommended to use the environment variable instead.
afterSignUpUrlstringThe full URL or path to navigate to after a successful sign up. Defaults to /. It's recommended to use the environment variable instead.
unsafeMetadataobjectAn object with the key and value for unsafeMetadata that will be saved to the user after sign up.
E.g. { "company": "companyID1234" }
initialValuesSignUpInitialValuesThe values used to prefill the sign-up fields with.

Usage with frameworks

The following example includes basic implementation of the <SignIn /> component. You can use this as a starting point for your own implementation.

You can embed the <SignUp /> component using the Next.js optional catch-all route(opens in a new tab). This allows you to redirect the user inside your application. The <SignUp /> component should be mounted on a public page.

/app/sign-up/[[...sign-up]]/page.tsx
import { SignUp } from "@clerk/nextjs";
 
export default function Page() {
  return <SignUp path="/sign-up" signInUrl="/sign-in" />;
}

You will notice a path prop is being passed to the SignUp /> component. This is because, by default, the routing strategy is set to path, requiring the path prop to be passed. In Next.js applications, you can either pass the path prop to the <SignUp /> component, or you can define the NEXT_PUBLIC_CLERK_SIGN_IN_URL and NEXT_PUBLIC_CLERK_SIGN_UP_URL environment variables.

The example below shows how to mount the <SignUp /> component on a page without a path prop. Select the .env.local tab to see an example of how to define the appropriate environment variables.

/pages/sign-up/[[...index]].tsx
import { SignUp } from "@clerk/nextjs";
 
const SignUpPage = () => (
  <SignUp />
);
export default SignUpPage;
.env.local
CLERK_SIGN_IN_URL=/sign-in
CLERK_SIGN_UP_URL=/sign-up
