Version 2

Note version 2 fixes possible CORs issues and includes a breaking change to return error as a Boolean. You can now get more information about the error (and success) from the new message property

Usage

import React, { useState } from 'react';
// import the hook
import { useMailChimp } from 'react-use-mailchimp-signup';

export const MyComponent = () => {
  const { error, loading, status, subscribe, message } = useMailChimp({
    action: `https://<YOUR-USER>.us18.list-manage.com/subscribe/post?u=XXXXXX&amp;id=XXXXXX`,
  });

  const [inputs, setInputs] = useState({});

  const handleInputChange = (event) => {
    event.persist();
    setInputs((inputs) => ({
      ...inputs,
      [event.target.name]: event.target.value,
    }));
  };

  const handleSubmit = (event) => {
    if (event) {
      event.preventDefault();
    }
    if (inputs) {
      subscribe(inputs);
    }
  };
