Apollo GraphQL without JavaScript

It's cool to see progressive enhancement being done even while using the fanciest of the fancy front-end technologies.

This is a button in a JSX React component that has a click handler applied directly to it that fires a data mutation Ajax request through Apollo GraphQL. That is about the least friendly environment for progressive enhancement I can imagine.

Hugo Giraudel writes that they do server-side rendering already, so the next tricky part is the click handler. Without JavaScript, the only mechanism we have for posting data is a <form>, so that's what they do. It submits to the /graphql endpoint with the data it needs to perform the mutation via hidden inputs, plus additional data on where to redirect upon success or failure.

Pretty neat.
