Recommended setup for jwt tokens

[ZempTime]

Hey. I'm converting a smallish API over from AMS onto jsonapi-rb. Loving the experience thus far. I have a question on how to do a thing.

I've got a registration endpoint for when users sign up.

  def create
    @user = User::SignUp.new(registration_params)

    if @user.save
      jwt = Auth.issue({user: @user.id, name: @user.name})
      render jsonapi: {jwt: jwt}, status: 201
    else
      render jsonapi: @user, status: 200, serializer: ActiveModel::Serializer::ErrorSerializer
    end
  end

For sad path, swapped out

# this:
      render jsonapi: @user, status: 200, serializer: ActiveModel::Serializer::ErrorSerializer
# for this: 
      render jsonapi_errors: @user.errors

And it just worked, all tests passing. Woo!

For the other part, where I'm serializing up a JWT, I basically got stopped and confused in the documentation on this page right here:

This behavior is customizable by overriding the jsonapi_class setting (or by supplying a class renderer option). Either set it to an explicit hash, or a hash with a dynamic default value for inferrence.

I got the impression I need to write some code somewhere, specifically tie a class to a hash or something somehow so I could use jsonapi-rb to serialize up my JWT.

shortly after, while listlessly scrolling upwards on the page unsure where to go, I then realized it was right there on the page, this link.

Anyway, I'm still not sure exactly what the right thing to do is. So I wanted to articulate in this issue, here's what I was trying to do, here's where I got confused, and ask for help.

What's the right way to serialize up my jwt? If I have a "virtual" resource that doesn't correspond with a db table, how can I get my endpoint working right away without needing to build out an entire mental model of how the rest of this works? that would be a great dip my toe in the pool moment, where I could dig into the rest of the docs at the point in time I need them.

But then I'd also like to offer to bulk up the documentation from the POV of someone using this library for the first time. Would you be open to me PR'ing in some "if you want this outcome, do this" quick and dirty examples for that getting started on rails page? And if it ends up being good, I'd be happy to PR in doc enhancements in other areas as I progress in my usage. :)

Anyway, hope this issue is in the right place, and thank you so much for your work on this. I'm planning on building cool things with it!
