How to use

  1. You will need to modify the EmailPassword.init(...) function call.
  2. Component overrides can be configured at override.components config object.
  3. Pick a component that you'd like to override by its key.
  4. Supply a React component against the key you have picked. Your custom component will get the original component as a prop.

Example#

import React from "react";import EmailPassword from "supertokens-auth-react/recipe/emailpassword";
EmailPassword.init({    override: {        components: {            /**             * In this case, the <EmailPasswordSignIn_Override> will render the original component             * wrapped in a div with an octocat picture above it.             */            EmailPasswordSignIn_Override: ({ DefaultComponent, ...props }) => {                return (                    <div>                        <img src="octocat.jpg" />                        <DefaultComponent {...props} />                    </div>                );            },        }    }});
Prebuilt sign in UI with custom image
important

Please make sure that the file in which this config is specified is a .tsx or .jsx file type.

Finding which component will be overridden#

To do that, you should use React Developer Tools extension which provides a component tree inspector.

Example#

Checking which component from the prebuilt UI will be overridden using React Developer Tools extension
  1. Look for the names defined in component override config and/or components ending in _Override in the component tree.
  2. Ensure that's the component you want to override
  3. Overide the component as stated above.

How do I render the original component#

Because the override function receives the original component as a parameter, you can render it. To do this, simply use it in JSX. Don't forget to supply original props by spreading them.

import React from "react";
const customComponent = ({ DefaultComponent, ...props }: { DefaultComponent: React.ComponentType }) => {    return (        <>            <h1>I'm a header that you added above original component</h1>            <DefaultComponent {...props} />        </>    )}
