By default, the <SignIn /> component handles signing in and signing up, but if you'd like to have a dedicated sign-up page, this guide shows you how to use the <SignUp /> component to build a custom sign-up page.
To set up a single sign-in-or-up page, follow the custom sign-in-or-up page guide.
<Steps> ## Build a sign-up page[!NOTE] Just getting started with Clerk and TanStack React Start? See the quickstart tutorial!
The following example demonstrates how to render the <SignUp /> component on a dedicated sign-up page using the TanStack Router catch-all route.
import { SignUp } from '@clerk/tanstack-react-start'
import { createFileRoute } from '@tanstack/react-router'
export const Route = createFileRoute('/sign-up/$')({
component: Page,
})
function Page() {
return <SignUp />
}
CLERK_SIGN_UP_URL environment variable to tell Clerk where the <SignUp /> component is being hosted.There are other environment variables that you can set to customize Clerk's redirect behavior, such as CLERK_SIGN_UP_FORCE_REDIRECT_URL. Learn more about these environment variables and how to customize Clerk's redirect behavior in the dedicated guide.
CLERK_SIGN_UP_URL=/sign-up
