Json-api-merge NPM

JSON API Merge

json-api-merge is a JSON:API specific redundant duplication algorithm for merging included resources into original data.

Getting Started

Requirements

Peer dependencies of Ramda and RamdaAdjunct.

ramda >= 0.19.0 <= 0.26.1
ramda-adjunct >=0.3.0

Installation

npm i json-api-merge

yarn add json-api-merge

Usage

ES2O19

const jsonApiData = {
  data: {
    id: 1,
    type: 'resource',
    attributes: {
      name: 'Resource name',
    },
    relationships: {
      related: {
        data: {
          id: 2,
          type: 'related_resource',
        },
      },
    },
  },
  included: [
    {
      id: 2,
      type: 'related_resource',
      attributes: {
        name: 'Related resource name',
      },
    },
  ],
};

import jsonApiMerge from 'json-api-merge'

jsonApiMerge(jsonApiData.included, jsonApiData.data)

Node

const jsonApiMerge = require('json-api-merge');

jsonApiMerge(jsonApiData.included, jsonApiData.data);

Result would be following data structure.

{
  id: 1,
  type: 'resource',
  attributes: {
   name: 'Resource name',
  },
  relationships: {
    related: {
      data: {
       id: 2,
       type: 'related_resource',
       attributes: {
         name: 'Related resource name',
       },
      },
    },
  },
}

The library can also process data in list format and can transform this:

{
  data: [
    {
      id: 1,
      type: 'resource',
      attributes: {
        name: 'Resource name',
      },
      relationships: {
        related: {
          data: {
            id: 2,
            type: 'related_resource',
          },
        },
      },
    }
  ],
  included: [
    {
      id: 2,
      type: 'related_resource',
      attributes: {
        name: 'Related resource name',
      },
    },
  ],
}

into this:

[
  {
    id: 1,
    type: 'resource',
    attributes: {
      name: 'Resource name',
    },
    relationships: {
      related: {
        data: {
          id: 2,
          type: 'related_resource',
          attributes: {
            name: 'Related resource name',
          },
        },
      },
    },
  }
]

Motivation

I was looking for a simple way how to merge the included into data without compromising data structures. All other libraries that I tested were opionated about how the resulting merge should look like. This library has no opinion and simply merged the included into data. It does nothing else.
