title: Processing credit cards in React/Node using only open source tech
body: <p>If you go out and look for how to process credit cards online, you will continuously get sent towards Paypal or Stripe (which are great options!).  These have great features, including nice client UIs, but they don't always fit the problem domain.</p>
  
  <p>I need to accept credit card payments to replace in-person payments for a business, which means no extra fees outside of what credit cards already charge.  This is for both Canada and the USA.  </p>
  
  <p>Is there an established "best pick" for open source frameworks for handling credit card payments in Node and React?</p>
