JSON:API Node Preview

A module to get node previews in JSON:API.

It adds a new endpoint for all JSON:API resources of type node, adding a
/preview string to the end of the original JSON:API path.

For example:

• Node / Article : /jsonapi/node/article/{UUID}/preview
• Node / Page : /jsonapi/node/page/{UUID}/preview
• etc

That endpoint is compatible with any other JSON:API parameters available
(fields, include, etc).

The expected workflow to make this module work is as following:

• Edit any node and click on "Preview" button
• A new window opens, with a URL like this: http://example.com/node/preview/1f8b435a-0026-4628-93f3-38ae7353ffbb/full
• Grab the UUID (the "8-4-4-4-12" chars, "1f8b435a-0026-4628-93f3-38ae7353ffbb" in this example)
• Execute a request to /jsonapi/node/article/1f8b435a-0026-4628-93f3-38ae7353ffbb/preview

Being a preview operation, this endpoint:

• is not cached.
• is authenticated, so it is only available to the same authenticated user that created the node preview (please do not open an issue about how to get anonymous access to node previews, since that is a security breach).

You can use any UUID to request the preview endpoint. If that UUID has not been
previewed, or the user making the request has not enough permissions, JSON:API
responds with a 404 error.
