Ember.js custom serializer for consistent JSON root

gistfile1.js

// API return format is as so:
// {
// 	data: [
// 		{
// 			name: 'foo'
// 		}, 
// 		{
// 			name: 'bar'
// 		}
// 	]
// }
// Ember expects:
// {
// 	posts: [
// 		{
// 			name: 'foo'
// 		}, 
// 		{
// 			name: 'bar'
// 		}
// 	]
// }

import Ember from 'ember';
import DS from "ember-data";

export default DS.RESTSerializer.extend({
	// Custom json root. The API returns objects in the "data" key.
	// We need to re-assign it to the singular version of the model name. 
	// So {data: {name: foo}} becomes {post: {name: foo}}
	extractSingle: function(store, primaryType, rawPayload, recordId) {
		var typeKey = primaryType.typeKey;
		payload[typeKey] = payload['data'];
		delete payload['data'];

		return this._super(store, primaryType, rawPayload, recordId);
	},
	// Custom json root. The API returns objects in the "data" key.
	// We need to re-assign it to the plural version of the model name. 
	// So {data: [{post1}, {post2}]} becomes {posts: [{post1},{post2}]}
	extractArray: function(store, primaryType, payload) {
		var pluralTypeKey = Ember.Inflector.inflector.pluralize(primaryType.typeKey);
		payload[pluralTypeKey] = payload['data'];
		delete payload['data'];

		return this._super(store, primaryType, payload);
	}
});

For ember data 3.24:

import RESTSerializer from '@ember-data/serializer/rest';

export default class SubscriptionSerializer extends RESTSerializer {
  normalizeSingleResponse(store, primaryModelClass, payload, id, requestType) {
    const typeKey = primaryModelClass.modelName;

    // My third party api does not respond with a root level key.
    let hash = { [typeKey]: payload };

    return super._normalizeResponse(store, primaryModelClass, hash, id, requestType, true);
  }
}
