What are you using today to serialize JSON APIs? I used ActiveModel::Serializer in the past but not sure if this is the right way today.
Looking for suggestions.
jsonapi-resources - https://github.com/cerebris/jsonapi-resources
I'm using active_model_serializers 0.10.x and they work pretty well for me (be aware there are quite a few significant differences between 0.8, 0.9 and 0.10).
