Mailto react Code Snippet in 2024

Renders a link formatted to send an email (mailto: link).

• Use the email, subject and body props to create a <a> element with an appropriate href attribute.
• Use encodeURIcomponent to safely encode the subject and body into the link URL.
• Render the link with children as its content.

const Mailto = ({ email, subject = '', body = '', children }) => {
  let params = subject || body ? '?' : '';
  if (subject) params += `subject=${encodeURIComponent(subject)}`;
  if (body) params += `${subject ? '&' : ''}body=${encodeURIComponent(body)}`;

  return <a href={`mailto:${email}${params}`}>{children}</a>;
};

ReactDOM.render(
  <Mailto email="foo@bar.baz" subject="Hello & Welcome" body="Hello world!">
    Mail me!
  </Mailto>,
  document.getElementById('root')
);
