Installation

pnpm dlx shadcn@latest add https://supabase.com/ui/r/social-auth-react.json

Usage

usage.tsx
import { LoginForm } from '@/registry/default/blocks/social-auth-react/components/login-form'export default function LoginPage() {  return <LoginForm className="mx-auto w-full max-w-sm" />}
  • Use as a simple GitHub sign-in entry point for a React application backed by Supabase.
  • Use on a dedicated login page when the application has a `/protected` route for authenticated users.
  • Use when you want the Supabase OAuth flow and environment-based client setup included in a registry block.
  • Use as a starting point before adding additional providers or custom branding.

Examples

Centered login page

Places the form in a constrained column on a page.

centered-login-page.tsx
import { LoginForm } from '@/registry/default/blocks/social-auth-react/components/login-form'export default function LoginPage() {  return (    <main className="flex min-h-screen items-center justify-center p-6">      <LoginForm className="w-full max-w-sm" />    </main>  )}

Login form with HTML div attributes

Passes standard div attributes alongside a custom class name.

login-form-with-html-div-attributes.tsx
import { LoginForm } from '@/registry/default/blocks/social-auth-react/components/login-form'export default function SignInSection() {  return (    <section aria-label="Sign in">      <LoginForm className="mx-auto max-w-md" data-testid="github-login-form" />    </section>  )}

Auth route layout

Uses the form inside a responsive authentication layout.

auth-route-layout.tsx
import { LoginForm } from '@/registry/default/blocks/social-auth-react/components/login-form'export default function AuthPage() {  return (    <div className="grid min-h-screen place-items-center bg-muted/30 p-4">      <LoginForm className="w-full max-w-sm" />    </div>  )}

API reference

PropTypeDefaultDescription
classNamestring | undefinedundefinedOptional CSS class names merged with the component's default `flex flex-col gap-6` classes.
...propsReact.ComponentPropsWithoutRef<'div'>undefinedAll other non-ref attributes and event handlers supported by a native `div`; they are spread onto the component's outer `div`.

Accessibility

  • The authentication control is a native submit button inside a form, with `type="submit"`.
  • The submit button is disabled while the OAuth request is pending, preventing repeated submissions.
  • The card title and description provide a visible heading and context for the sign-in action.
  • Authentication errors are rendered as visible text with a destructive color, but the source does not add `role="alert"`, `aria-live`, or an explicit association between the error and the button.
  • The loading state is communicated by changing the button text to “Signing in...”; no separate loading icon or live-region announcement is provided.
