<SignUp /> component

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.

The <SignUp/> and <SignIn/> components cannot render when a user is already signed in, unless the application allows multiple sessions. If a user is already signed in and the application only allows a single session, Clerk will redirect the user to the Home URL instead.

Properties

All props are optional.

Name	Type	Description
`appearance`	`Appearance \| undefined`	Optional 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, such as `NEXT_PUBLIC_CLERK_SIGN_IN_URL`, this will be set to `path`.
`path`	`string`	The 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.

`unsafeMetadata`	`object`	An object with the key and value for `unsafeMetadata` that will be saved to the user after sign up. For example: `{ "company": "companyID1234" }`
`initialValues`	`SignUpInitialValues`	The 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.

The following example demonstrates how you can use the <SignUp /> component on a public page.

If you would like to create a dedicated /sign-up page in your Next.js application, check out the dedicated guide..

app/page.tsx
import { SignUp, useUser } from "@clerk/nextjs";
 
export default function Home() {
  const { user } = useUser();
 
  if (!user) {
    return <SignUp />;
  }
 
  return <div>Welcome!</div>;
}

sign-up.jsx
import { SignUp } from "@clerk/clerk-react";
 
function SignUpPage() {
  return <SignUp />;
}

app/routes/sign-up/$.tsx
import { SignUp } from "@clerk/remix";
 
export default function SignUpPage() {
  return (
    <div style={{ border: "2px solid blue", padding: "2rem" }}>
      <h1>Sign Up route</h1>
      <SignUp routing="path" path="/sign-up" />
    </div>
  );
}

/pages/sign-up.js
import { SignUp } from "gatsby-plugin-clerk";
 
export default function SignUpPage() {
  return (
    <div style={{ border: "2px solid blue", padding: "2rem" }}>
      <h1>Sign Up route</h1>
      <SignUp routing="path" path="/sign-up" />
    </div>
  );
}

Usage with JavaScript

The following methods available on an instance of the Clerk class are used to render and control the <SignUp /> component:

The following examples assume that you have followed the quickstart in order to add Clerk to your JavaScript application.

Render the <SignUp /> component to an HTML <div> element.


function mountSignUp(node: HTMLDivElement, props?: SignUpProps): void;

Name	Type	Description
`node`	`HTMLDivElement`(opens in a new tab)	The `<div>` element used to render in the `<SignUp />` component
`props?`	`SignUpProps`	The properties to pass to the `<SignUp />` component.

index.ts
import Clerk from "@clerk/clerk-js";
 
// Initialize Clerk with your Clerk publishable key
const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
document.getElementById("app").innerHTML = `
  <div id="sign-up"></div>
`;
 
const signUpDiv = document.getElementById("sign-up");
 
clerk.mountSignUp(signUpDiv);

index.js
<!-- Add a <div id="sign-up"> element to your HTML -->
<div id="sign-up"></div>
 
<!-- Initialize Clerk with your
Clerk Publishable key and Frontend API URL -->
<script
  async
  crossorigin="anonymous"
  data-clerk-publishable-key="{{pub_key}}"
  src="https://{{fapi_url}}/npm/@clerk/clerk-js@latest/dist/clerk.browser.js"
  type="text/javascript"
></script>
 
<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    const signUpDiv = document.getElementById("sign-up");
 
    Clerk.mountSignUp(signUpDiv);
  });
</script>

Unmount and run cleanup on an existing <SignUp /> component instance.


function unmountSignUp(node: HTMLDivElement): void;

Name	Type	Description
`node`	`HTMLDivElement`(opens in a new tab)	The container `<div>` element with a rendered `<SignUp />` component instance

index.ts

const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
document.getElementById("app").innerHTML = `
  <div id="sign-up"></div>
`;
 
const signUpDiv = document.getElementById("sign-up");
 
clerk.mountSignUp(signUpDiv);
 
// ...
 
clerk.unmountSignUp(signUpDiv);

index.js
<!-- Add a <div id="sign-up"> element to your HTML -->
<div id="sign-up"></div>
 
<!-- Initialize Clerk with your

<script
  async

<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    const signUpDiv = document.getElementById("sign-up");
 
    Clerk.mountSignUp(signUpDiv);
 
    // ...
 
    Clerk.unmountSignUp(signUpDiv);
  });
</script>

Opens the <SignUp /> component as an overlay at the root of your HTML body element.


function openSignUp(props?: SignUpProps): void;

Name	Type	Description
`props?`	`SignUpProps`	The properties to pass to the `<SignUp />` component

index.ts
import Clerk from "@clerk/clerk-js";
 
// Initialize Clerk with your Clerk publishable key

clerk.openSignUp();

index.html

<script

<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    Clerk.openSignUp();
  });
</script>

Closes the sign up overlay.


function closeSignUp(): void;

const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
clerk.openSignUp();
 
// ...
 
clerk.closeSignUp();
