Grape::Jsonapi

Use jsonapi-serializer with Grape.

Installation

Add grape-jsonapi to your Gemfile.

gem 'grape-jsonapi', require: "grape_jsonapi"

Usage

Tell your API to use Grape::Formatter::Jsonapi

class API < Grape::API
  content_type :jsonapi, "application/vnd.api+json"
  formatter :json, Grape::Formatter::Jsonapi
  formatter :jsonapi, Grape::Formatter::Jsonapi
end

Use render to specify JSONAPI options

get "/" do
  user = User.find("123")
  render user, include: [:account]
end

Use a custom serializer

get "/" do
  user = User.find("123")
  render user, serializer: 'CustomUserSerializer'
end

Or

get "/" do
  user = User.find("123")
  render CustomUserSerializer.new(user).serialized_json
end

Model parser for response documentation

When using Grape with Swagger via grape-swagger, you can generate response documentation automatically via the provided following model parser:

# FastJsonapi serializer example

# app/serializers/base_serializer.rb
class BaseSerializer; end
# app/serializers/user_serializer.rb
class UserSerializer < BaseSerializer
  include JSONAPI::Serializer

  set_type :user
  has_many :orders

  attributes :name, :email
end

# config/initializers/grape_swagger.rb
GrapeSwagger.model_parsers.register(GrapeSwagger::Jsonapi::Parser, BaseSerializer)

# Your grape API endpoint
desc 'Get current user' do
  success code: 200, model: UserSerializer, message: 'The current user'
# [...]
end

Note that you need the grape-swagger gem for this to work, otherwise it will throw an error.
