fast_jsonapi_serialization

🚀 Ultra-Fast JSON Serialization with fast_jsonapi​

Replace Rails’ default to_json or ActiveModelSerializers with fast_jsonapi to cut CPU overhead. It uses optimized C extensions and precompiled serialization trees.

# app/serializers/user_serializer.rb
class UserSerializer
  include FastJsonapi::ObjectSerializer
  set_key_transform :camel_lower
  attributes :id, :name, :email
  has_many :articles
end
# In controller
render json: UserSerializer.new(User.includes(:articles).limit(1000)).serialized_json

Benchmark this against render json: users to see 3–5× speedups in large‑payload scenarios.
