Build your own sign-in-or-up page for your Remix app with Clerk

This guide shows you how to use the <SignIn /> component to build a custom page that allows users to sign in or sign up within a single flow.

To set up separate sign-in and sign-up pages, follow this guide, and then follow the custom sign-up page guide.

Note

Just getting started with Clerk and Remix? See the quickstart tutorial!

Build a sign-in-or-up page

The following example demonstrates how to render the <SignIn /> component on a dedicated page using the Remix optional route.

app/routes/sign-in.$.tsx
import { SignIn } from '@clerk/remix'

export default function Page() {
  return <SignIn />
}

Configure your sign-in-or-up page

  • Set the CLERK_SIGN_IN_URL environment variable to tell Clerk where the <SignIn /> component is being hosted.
  • Set CLERK_SIGN_IN_FALLBACK_REDIRECT_URL as a fallback URL incase users visit the /sign-in route directly.
  • Set CLERK_SIGN_UP_FALLBACK_REDIRECT_URL as a fallback URL incase users select the 'Don't have an account? Sign up' 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.

.env
CLERK_SIGN_IN_URL=/sign-in
CLERK_SIGN_IN_FALLBACK_REDIRECT_URL=/
CLERK_SIGN_UP_FALLBACK_REDIRECT_URL=/
  • Set the signInUrl property to your ClerkApp options to tell Clerk where the <SignIn /> component is being hosted.
  • Set the signInFallbackRedirectUrl property to a fallback URL incase users visit the /sign-in route directly.
  • Set the signUpFallbackRedirectUrl property to a fallback URL incase users select the 'Don't have an account? Sign up' 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.

app/root.tsx
export default ClerkApp(App, {
  publishableKey: PUBLISHABLE_KEY,
  signInUrl: '/sign-in',
  signInFallbackRedirectUrl: '/',
  signUpFallbackRedirectUrl: '/',
})

Visit your new page

Run your project with the following terminal command from the root directory of your project:

terminal
npm run dev
terminal
yarn dev
terminal
pnpm dev
terminal
bun dev

Visit your new custom page locally at localhost:3000/sign-in.
