A simple heroku-ready Hapi.js app (& jQuery Plugin) for enabling Ajax Style Mailchimp Form Opt-ins without requiiing the subscriber's confirmation via email.

Grab a Mailchimp API Key, and deploy this to Heroku via the Heroku Button.

You'll need your App's URL for the next step.

Include mailchimp-single-opt-in.jquery.js, and setup a form like so:

<form id="mailchimp-form">
  <input type="email" />
</form>

And JS:

$('#mailchimp-form').mailchimpSingleOptIn({
  listID: MAILCHIMP_LIST_ID,
  url: HEROKU_APP_URL,
  onSubmit() {},
  onError(request) {},
  onSuccess(request) {}
});
