  • jsonapi-mapper JSON API-Compliant Serialization for your Node ORM.
  • jaysonapi jaysonapi is a framework agnostic JSON API v1.0.0 serializer. jaysonapi provides more of a functional approach to serializing your data. Define a serializer with a type and schema, and call serialize on it passing in the data, included, meta, errors, etc. as a plain object.
  • json-api-ify serialize the ** out of your data. json api v1.0 complaint.

Ruby

  • Jsonapi-for-rails empowers your JSONAPI compliant Rails APIs. Implement your APIs with very little coding.
  • ActiveModel::Serializers is one of the original exemplar implementations, but is slightly out of date at the moment.

  • RestPack::Serializer implements the read elements of json-api. It also supports paging and side-loading.
  • Oat ships with a JSON API adapter.
  • JSONAPI::Resources provides a complete framework for developing a JSON API server. It is designed to work with Rails, and provides routes, controllers, and serializers.

  • neoapi serializes JSON API–compliant responses from neomodel StructuredNodes for Neo4j data
  • py-jsonapi is a toolkit for building a JSON API. Can be extended easily to work with every web framework and database driver. Comes with support for flask, tornado, mongoengine and sqlalchemy.
  • xamoom-janus is a Python module to easily and fast extend Python web frameworks like Flask or BottlyPy with json:api functionality. Also offers a flexible mechanism for data mapping and hooks to intercept and extend its functionality according to your projects needs.

Go
