Apple Signin Setup

Deatiled confuguration instructions can be found at blog post and Apple docs and official apple docs for webpage signin.

OR

Usage

Checkout the demo for a quick start!

import AppleSignin from 'react-apple-signin-auth';

/** Apple Signin button */
const MyAppleSigninButton = () => (
  <AppleSignin
    /** Auth options passed to AppleID.auth.init() */
    authOptions={{
      /** Client ID - eg: 'com.example.com' */
      clientId: 'com.example.web',
      /** Requested scopes, seperated by spaces - eg: 'email name' */
      scope: 'email name',
      /** Apple's redirectURI - must be one of the URIs you added to the serviceID - the undocumented trick in apple docs is that you should call auth from a page that is listed as a redirectURI, localhost fails */
      redirectURI: 'https://example.com',
      /** State string that is returned with the apple response */
      state: 'state',
      /** Nonce */
      nonce: 'nonce',
      /** Uses popup auth instead of redirection */
      usePopup: ${authOptions.usePopup},
    }} // REQUIRED
    /** General props */
    uiType="dark"
    /** Extra controlling props */
    /** Called upon signin success in case authOptions.usePopup = true -- which means auth is handled client side */
    onSuccess={(response) => console.log(response)} // default = undefined
    /** Called upon signin error */
    onError={(error) => console.error(error)} // default = undefined
    /** Skips loading the apple script if true */
    skipScript={false} // default = undefined
    /** Apple image props */
    iconProp={{ style: { marginTop: '10px' } }} // default = undefined
    /** render function - called with all props - can be used to fully customize the UI by rendering your own component  */
    render={(props) => <button {...props}>My Custom Button</button>}
  />
);

export default MyAppleSigninButton;

Raw JS functionality

a module called appleAuthHelpers is also exported to allow you to use the functionality without using the UI or relying on React. This works with any kind of frontend JS, eg: react, vue, etc...

import { appleAuthHelpers } from 'react-apple-signin-auth';
// OR
// import appleAuthHelpers from 'react-apple-signin-auth/dist/appleAuthHelpers'; // @unstable - might change with upgrades

/**
 * perform apple signIn operation
 */
appleAuthHelpers.signIn({
  authOptions: {
    // same as above
  },
  onSuccess: (response) => console.log(response),
  onError: (error) => console.error(error),
});

// OR

/** promisified version - promise resolves with response on success or undefined on error -- note that this only work with usePopup: true */
const response = await appleAuthHelpers.signIn({
  authOptions: {
    // same as above
  },
  onError: (error) => console.error(error),
});

if (response) {
  console.log(response);
} else {
  console.error('Error performing apple signin.');
}

Server-side authentication (nodeJS backend)

Another library exists for server/backend support for Apple signin apple-signin-auth

Usage

• Install the library yarn add apple-signin-auth OR npm i apple-signin-auth
• Implement JWT verification logic

  const appleSignin = require("apple-signin-auth");
  
  
  const { authorization, user } = req.body;
  
  try {
    const { sub: userAppleId } = await appleSignin.verifyIdToken(
      authorization.id_token, // We need to pass the token that we wish to decode.
      {
        audience: "com.example.web", // client id - The same one we used on the frontend, this is the secret key used for encoding and decoding the token.
        nonce: 'nonce' // nonce - The same one we used on the frontend - OPTIONAL
      }
    );
  } catch (err) {
    // Token is not verified
    console.error(err);
  }
