Use integer / number id in Ember without canary build

application.js

// app/serializers/application.js
import DS from 'ember-data';
import Ember from 'ember';
import coerceId from "ember-data/-private/system/coerce-id";

var get = Ember.get;

export default DS.JSONSerializer.extend({
  extractId(modelClass, resourceHash) {
    var primaryKey = get(this, 'primaryKey');
    var id = resourceHash[primaryKey];
    return parseInt(coerceId(id), 10);
  }
});

store.js

// app/services/store.js
import DS from 'ember-data';
import coerceId from "ember-data/-private/system/coerce-id";
import { assert } from "ember-data/-private/debug";

export default DS.Store.extend({
  _internalModelForId(modelName, inputId) {
    // heimdall.increment(this._internalModelForId);
    let modelClass = this.modelFor(modelName);
    let id = parseInt(coerceId(inputId), 10);
    let idToRecord = this.typeMapFor(modelClass).idToRecord;
    let internalModel = idToRecord[id];

    if (!internalModel || !idToRecord[id]) {
      internalModel = this.buildInternalModel(modelClass, id);
    }

    return internalModel;
  },

  updateId(internalModel, data) {
    var oldId = internalModel.id;
    var id = parseInt(coerceId(data.id), 10);

    assert("An adapter cannot assign a new id to a record that already has an id. " + internalModel + " had id: " + oldId + " and you tried to update it with " + id + ". This likely happened because your server returned data in response to a find or update that had a different id than the one you sent.", oldId === null || id === oldId);

    this.typeMapFor(internalModel.type).idToRecord[id] = internalModel;

    internalModel.setId(id);
  },
});
