Normalizr takes JSON and a schema and replaces nested entities with their IDs, gathering all entities in dictionaries.

Normalizer.js

// App/Services/Normalizer.js

import { Schema, arrayOf, normalize } from 'normalizr'
import { camelizeKeys } from 'humps'

const normalizer = (data, schema) => {
  const camelizedJson = camelizeKeys(data)
  return normalize(camelizedJson, schema)
}
