Ember Data 2.0 Serializer:

In Ember Data a Serializer is used to serialize and deserialize records when they are transferred in and out of an external source. This process involves normalizing property names, transforming attribute values and serializing relationships.

JSONAPISerializer supports the http://jsonapi.org/ spec and is the serializer recommended by Ember Data.

This serializer normalizes a JSON API payload that looks like:

app/models/player.js
import DS from 'ember-data';

export default DS.Model.extend({
  name: DS.attr('string'),
  skill: DS.attr('string'),
  gamesPlayed: DS.attr('number'),
  club: DS.belongsTo('club')
});
app/models/club.js
import DS from 'ember-data';

export default DS.Model.extend({
  name: DS.attr('string'),
  location: DS.attr('string'),
  players: DS.hasMany('player')
});
  {
    "data": [
      {
        "attributes": {
          "name": "Benfica",
          "location": "Portugal"
        },
        "id": "1",
        "relationships": {
          "players": {
            "data": [
              {
                "id": "3",
                "type": "players"
              }
            ]
          }
        },
        "type": "clubs"
      }
    ],
    "included": [
      {
        "attributes": {
          "name": "Eusebio Silva Ferreira",
          "skill": "Rocket shot",
          "games-played": 431
        },
        "id": "3",
        "relationships": {
          "club": {
            "data": {
              "id": "1",
              "type": "clubs"
            }
          }
        },
        "type": "players"
      }
    ]
  }

to the format that the Ember Data store expects.

Customizing meta

Since a JSON API Document can have meta defined in multiple locations you can use the specific serializer hooks if you need to customize the meta.

One scenario would be to camelCase the meta keys of your payload. The example below shows how this could be done using normalizeArrayResponse and extractRelationship.

app/serializers/application.js
export default JSONAPISerializer.extend({
  normalizeArrayResponse(store, primaryModelClass, payload, id, requestType) {
    let normalizedDocument = this._super(...arguments);

    // Customize document meta
    normalizedDocument.meta = camelCaseKeys(normalizedDocument.meta);

    return normalizedDocument;
  },

  extractRelationship(relationshipHash) {
    let normalizedRelationship = this._super(...arguments);

    // Customize relationship meta
    normalizedRelationship.meta = camelCaseKeys(normalizedRelationship.meta);

    return normalizedRelationship;
  }
});
