Usage

import React, { useState } from 'react';
import {
  ContinentCountrySelect,
  deserializeCountries,
  serializeCountries
} from 'react-continent-country-select';
import 'react-continent-country-select/dist/index.css';
import continents from 'react-continent-country-select/dist/continent_countries.json';

// pre-selected values from e.g. API endpoint
const countries = ['be', 'nl', 'hr'];
// Deserialize data: convert ['be', 'nl', 'hr'] to { BE: true, NL: true, HR: true }
const deserializedCountries = deserializeCountries(countries);

const App = () => {
  const [selectedCountries, setSelectedCountries] = useState({
    ...deserializedCountries
  });

  // You can create custom country component
  const CountryComponent = ({ country }) => {
    const code = country.code.toLowerCase();
    const label = `${country.name} (+${country.dial_code})`;

    return (
      <span>
        <i
          style={{ width: '30px' }}
          className={`flag-icon flag-icon-${code} mr-1`}
        />
        {label}
      </span>
    );
  };

  const onChange = selected => setSelectedCountries({ ...selected });

  const onSerializeData = () => {
    // Serialize selected countries
    // The second boolean param is used for serializing data depending on your specific needs (upper/lower case)
    const serializedCountries = serializeCountries(selectedCountries, false);

    alert(`Selected Countries: \n ${JSON.stringify(serializedCountries)}`);
  };

  return (
    <div>
      <ContinentCountrySelect

          EU: true,
          NA: false,
          SA: false
        }} // Not required - by default everything is set to false
        translations={{
          toggleText: 'Toggle',
          notFoundText: 'No countries found.'
        }} // Not required
        customComponent={CountryComponent} // Not required
        onChange={onChange} // Required
      />
      <button type="button" onClick={onSerializeData}>
