using nextjs, create a new page that returns a div with an input that takes in a persons name and the div contains “hello” plus the name from the input in typescript

To create a new page with an input that takes in a person's name and displays a greeting message using Next.js, React, and TypeScript, you need to follow these steps:

Create a new page in the pages directory of your Next.js app. Let's call it GreetingPage.tsx.
Add the necessary imports for React and Next.js in the file.


import React, { useState } from 'react';
import Head from 'next/head';

3 lines

Define the component function and state for the input field:


const GreetingPage: React.FC = () => {
  const [name, setName] = useState<string>('');

  const handleNameChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setName(event.target.value);
  };

  return (
    <>
      <Head>
        <title>Greeting Page</title>
      </Head>
      <div>
        <label htmlFor="name-input">Enter your name:</label>
        <br />
        <input
          type="text"
          id="name-input"
          value={name}
          onChange={handleNameChange}
        />
        <div>Hello {name ? name : 'stranger'}!</div>
      </div>
    </>
  );
};

export default GreetingPage;

29 lines

In the component's JSX, create a label for the input field and an <input> tag with an onChange event handler that updates the name state whenever the user types in their name.
Finally, add a div tag that displays the greeting message with the person's name in it. If the name state is falsy, the message defaults to "Hello stranger!".

With these steps, you have created a new page with an input that takes in a person's name and displays a greeting message using TypeScript in a Next.js app.
