Implement the auth0 functions etc. from the LOGIN code to the REACT code to it takes the email from the input and trigger when you click the Button.

LOGIN code:
 
 
 
 
 Auth0 Login Callback demo
 
 
 Passwordless Start

 
 
 

 
 
REACT code:
import React from 'react';
import Button from '../components/Button';
import { Input } from '../components/styled';

export default function OrdersPage() {

 return (
 
 
 
 Login to Marts
==============
 
 Enter your email to sign in.
 
 
 Login
 
 


 );
}
user
to integrate the auth0 login functionality from the login code into the react code, follow these steps:

1. install the auth0 spa sdk:
```css
npm install --save @auth0/auth0-spa-js
```
1. create an `auth0provider` component to wrap your entire application in. this will make the auth0 client instance available throughout the app. create a new file `auth0-provider.js`:
```javascript
import react, { usestate, useeffect, createcontext } from "react";
import createauth0client from "@auth0/auth0-spa-js";

const auth0context = createcontext();

export const auth0provider = ({ children }) => {
  const [auth0client, setauth0client] = usestate(null);

  useeffect(() => {
    const initauth0 = async () => {
      const client = await createauth0client({
        domain: "marts.eu.auth0.com",
        client_id: "t0w7wrn696q2uxft3cmvvqluqbjxdyzj",
        redirect_uri: window.location.origin,
      });
      setauth0client(client);
    };
    initauth0();
  }, []);

  return (
    <auth0context.provider value={auth0client}>
      {auth0client && children}
    </auth0context.provider>
  );
};

export const useauth0 = () => {
  const auth0client = react.usecontext(auth0context);
  return auth0client;
};
```
1. wrap your application with the `auth0provider` component in `index.js`:
```javascript
import react from 'react';
import reactdom from 'react-dom';
import app from './app';
import { auth0provider } from './auth0-provider';

reactdom.render(
  <react.strictmode>
    <auth0provider>
      <app />
    </auth0provider>
  </react.strictmode>,
  document.getelementbyid('root')
);
```
1. modify the `orderspage` component to use the auth0 client:
```javascript
import react, { usestate } from "react";
import button from "../components/button";
import { input } from "../components/styled";
import { useauth0 } from "./auth0-provider";

export default function orderspage() {
  const auth0client = useauth0();
  const [email, setemail] = usestate("");

  const handlelogin = async () => {
    if (email) {
      auth0client.passwordlessstart(
        {
          connection: "email",
          send: "link",
          email,
        },
        (err, result) => {
          if (err) return console.error(err);
          alert("done! check your email");
          setemail("");
        }
      );
    }
  };

  return (
    <div classname="flex h-screen items-center justify-center bg-gray-200">
      <div classname="w-11/12 md:w-5/6 lg:w-1/2 p-8 bg-white rounded shadow">
        <div classname="mb-4">
          <h1 classname="text-3xl font-bold mb-4 text-center">
            auth0 login callback demo
          </h1>
          <p classname="text-gray-700">
            passwordless start

```css
          </p>
        </div>
        <div classname="mb-4">
          <h1 classname="text-3xl font-bold mb-4 text-center">
            marts passwordless login
          </h1>

    if (email) {
      auth0Client.passwordlessStart(
        {

        (err, result) => {

          alert("Done! Check your email");
          setEmail("");
