I solved it in this way. I used 'react-datepicker' v4.11.0.

import moment from 'moment';
import React, { useState } from 'react';
import DatePicker from 'react-datepicker';

const DatePickerComponent = () => {
  const [startDate, setStartDate] = useState(1659312000000);

  const year = moment(startDate).format('yyyy');

  return (
    <div>
      <h1>Date Picker</h1>
      <p>Selected year: {year}</p>
      <DatePicker
        selected={startDate}
        onChange={(date) => setStartDate(date)}
        showYearPicker
        dateFormat="yyyy"
      />
    </div>
  );
};

export default DatePickerComponent;

Find a working link here: https://stackblitz./edit/react-tfzvsm?file=src%2Fdate-picker.jsx

if i understand correctly You want it to be displayed for only a year, but what Displayed as "Thu Jan 01 1970 07:00:01 GMT+0700". You need to use .getFullYear() in onChange , this is the method I tried and it works.

    import { useState } from "react";
    import DatePicker from "react-datepicker";
    
    const [savedate, setSavedate] = useState();
    
    const <your ponent> = () => {
    
      return() {
            <DatePicker
               id="DatePicker"
               type="string"
               className="text-primary text-center"
               selected={birthYear}
               onChange={(date) => setSavedate(date.getFullYear())}
               showYearPicker
               dateFormat="yyyy"
               yearItemNumber={9}
               required
            />
      }
    }

There is a library called react-datetime.We can pick only year using this library. Install the library using this mand:npm i react-datetime
