Build your own sign-up page for your React Router app with Clerk
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.
Build a sign-up page
The following example demonstrates how to render the <SignUp /> component on a dedicated sign-up page using the React Router Splat route.
import { SignUp } from '@clerk/react-router'
export default function SignUpPage() {
return (
<div>
<h1>Sign up route</h1>
<SignUp />
</div>
)
}Configure routes
React Router expects you to define routes in app/routes.ts. Add the previously created sign-up page to your route configuration.
import { type RouteConfig, index, route } from '@react-router/dev/routes'
export default [
index('routes/home.tsx'),
route('sign-in/*', 'routes/sign-in.tsx'),
route('sign-up/*', 'routes/sign-up.tsx'),
] satisfies RouteConfigConfigure redirect behavior
- Set the
CLERK_SIGN_UP_URLenvironment variable to tell Clerk where the<SignUp />component is being hosted. - Set
CLERK_SIGN_UP_FALLBACK_REDIRECT_URLas a fallback URL incase users visit the/sign-uproute directly. - Set
CLERK_SIGN_IN_FALLBACK_REDIRECT_URLas a fallback URL incase users select the 'Already have an account? Sign in' link at the bottom of the component.
Learn more about these environment variables and how to customize Clerk's redirect behavior in the dedicated guide.
CLERK_SIGN_UP_URL=/sign-up
CLERK_SIGN_UP_FALLBACK_REDIRECT_URL=/
CLERK_SIGN_IN_FALLBACK_REDIRECT_URL=/These values control the behavior of the <SignUp /> and <SignIn /> components and when you visit the respective links at the bottom of each component.
