Ruby JSONAPI

A fast and efficient JSON:API serializer for Ruby objects.

Ruby JSONAPI is a fork of the jsonapi-serializer gem (which was itself forked from Netflix's fast_jsonapi). This library provides a simple and performant way to serialize your Ruby objects according to the JSON:API specification.

The jsonapi-serializer gem provides excellent serialization performance but lacks full JSON:API specification support. This fork aims to:

1. Complete the JSON:API specification implementation
2. Add features for complex API requirements
3. Maintain backward compatibility with jsonapi-serializer
4. Preserve the performance benefits that made the original library valuable

Our focus is to create a more complete toolset while ensuring existing code continues to work without major changes.

• Fast JSON:API serialization
• ActiveModel Serializer-like DSL
• Relationship support (has_many, belongs_to, has_one)
• Compound documents (included resources)
• Resource-level caching
• Conditional attributes and relationships
• Key transformation (camel, dash, underscore)
• Rails integration with generators

• Complete Error Objects - Full JSON:API error structure with source pointers
• Filtering - Standard filtering with multiple operators and strategies
• Sorting & Pagination - Multi-field sorting and standard pagination
• Enhanced Relationships - Better handling of complex relationship structures
• Request Parsing - Converting incoming JSON:API documents to Ruby objects
• Resource Permissions - Field-level and relationship-level access controls
• HTTP Content Negotiation - Standard media type and header support
• Atomic Operations - Multiple create/update/delete operations in a single request
• Extensions Support - Implementation of the extensions mechanism

Ruby JSONAPI is significantly faster than alternatives like ActiveModelSerializer:

Benchmarks are inherited from jsonapi-serializer. See performance methodology for details.

Add this line to your application's Gemfile:

gem 'ruby_jsonapi'

Then execute:

$ bundle install

Define your serializer:

class MovieSerializer
  include JSONAPI::Serializer

  attributes :name, :year

  has_many :actors
  belongs_to :director
end

Serialize your objects:

# Single object
serializer = MovieSerializer.new(movie)
json_string = serializer.serializable_hash.to_json

# Collection
serializer = MovieSerializer.new(movies)
json_string = serializer.serializable_hash.to_json
