JSON API Serializer

JSONAPI Serializer Logo

Build Status npm version download

A Node.js framework agnostic library for (de)serializing your data to JSON API (1.0 compliant).

psst: If you need an off-the-shelf admin panel for your app, check out what I build in my day job at forestadmin.com - it uses jsonapi-serializer to de/serialize data data coming from/to the APIs.

Installation

$ npm install jsonapi-serializer

Documentation

Serialization

var JSONAPISerializer = require('jsonapi-serializer').Serializer;
new JSONAPISerializer(type, opts).serialize(data);

The function JSONAPISerializer takes two arguments:

Calling the serialize method on the returned object will serialize your data (object or array) to a compliant JSONAPI document.

Available serialization option (opts argument)

Examples

Simple usage:

var data = [
  { id: 1, firstName: 'Sandro', lastName: 'Munda' },
  { id: 2, firstName: 'John', lastName: 'Doe' }
];
var JSONAPISerializer = require('jsonapi-serializer').Serializer;

var UserSerializer = new JSONAPISerializer('users', {
  attributes: ['firstName', 'lastName']
});

var users = UserSerializer.serialize(data);

// `users` here are JSON API compliant.

The result will be something like:

{
  "data": [{
    "type": "users",
    "id": "1",
    "attributes": {
      "first-name": "Sandro",
      "last-name": "Munda"
    }
  }, {
    "type": "users",
    "id": "2",
    "attributes": {
      "first-name": "John",
      "last-name": "Doe"
    }
  }]
}

Deserialization

var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;
new JSONAPIDeserializer(opts).deserialize(data);

The function JSONAPIDeserializer takes one argument:

Calling the deserialize method on the returned object will deserialize your data (JSONAPI document) to a plain javascript object.

Available deserialization option (opts argument)

Examples

Simple usage:

{
  data: [{
    type: 'users',
    id: '1',
    attributes: {
      'first-name': Sandro,
      'last-name': Munda
    }
  }, {
    type: 'users',
    id: '2',
    attributes: {
      'first-name': 'John',
      'last-name': 'Doe'
    }
  }]
}
var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;

new JSONAPIDeserializer().deserialize(jsonapi, function (err, users) {
  // `users` is...
});
[
  { id: 1, firstName: 'Sandro', lastName: 'Munda' },
  { id: 2, firstName: 'John', lastName: 'Doe' }
];

Relationship:

{
  data: [{
    type: 'users',
    id: '54735750e16638ba1eee59cb',
    attributes: {
      'first-name': 'Sandro',
      'last-name': 'Munda'
    },
    relationships: {
      address: {
        data: { type: 'addresses', id: '54735722e16620ba1eee36af' }
      }
    }
  }, {
    type: 'users',
    id: '5490143e69e49d0c8f9fc6bc',
    attributes: {
      'first-name': 'Lawrence',
      'last-name': 'Bennett'
    },
    relationships: {
      address: {
        data: { type: 'addresses', id: '54735697e16624ba1eee36bf' }
      }
    }
  }]
}
var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;

new JSONAPIDeserializer({
  addresses: {
    valueForRelationship: function (relationship) {
      return {
        id: relationship.id,
        'address-line1': '406 Madison Court',
        'zip-code': '49426',
        country: 'USA'
      };
    }
  }
}).deserialize(jsonapi, function (err, users) {
  // `users` is...
});
[{
  id: '54735750e16638ba1eee59cb',
  'first-name': 'Sandro',
  'last-name': 'Munda',
  address: {
    id: '54735722e16620ba1eee36af',
    'address-line1': '406 Madison Court',
    'zip-code': '49426',
    country: 'USA'
  }
}, {
  id: '5490143e69e49d0c8f9fc6bc',
  'first-name': 'Lawrence',
  'last-name': 'Bennett',
  address: {
    id: '54735697e16624ba1eee36bf',
    'address-line1': '406 Madison Court',
    'zip-code': '49426',
    country: 'USA'
  }
}]

Notes on Promises

The deserialization option valueForRelationship supports returning a Promise and so this library uses Promises under the hood. bluebird was previously used as a dependency, but due to bundle size concerns on both node and the web it was replaced with native promises.

bluebird is definitely more performant than native Promises. If performance is a major concern Promise can be globally polyfilled

Error serialization

var JSONAPIError = require('jsonapi-serializer').Error;
var error = new JSONAPIError(opts);

The function JSONAPIError takes one argument:

Available error option (opts argument)

Examples

Simple usage:

var JSONAPIError = require('jsonapi-serializer').Error;

var errors = new JSONAPIError({
  code: '123',
  source: { 'pointer': '/data/attributes/first-name' },
  title: 'Value is too short',
  detail: 'First name must contain at least three characters.'
});

// `errors` here are JSON API compliant.

The result will be something like:

{
  "errors": [
    {
      "code":   "123",
      "source": { "pointer": "/data/attributes/first-name" },
      "title":  "Value is too short",
      "detail": "First name must contain at least three characters."
    }
  ]
}
