Configurable camelizing type values

As was discovered in PR https://github.com/yury-dymov/json-api-normalizer/pull/33 there is potential issue with camelizing type’s values inside relationships data objects.

Despite camelizing option explicitly called: camelizeKeys: true it’s affecting type values too. It will be great to have separate configurable option to camelize type values.

Input:

const json = {
  data: [
    {
      type: 'post',
      relationships: {
        'rel1-to-camelize': {
          data: [
            {
              id: 4,
              type: 'type1-to-camelize',
            },
          ],
        },
      },
      id: 2620,
    },
  ],
};

Output:

const output = {
  post: {
    2620: {
      type: 'post',
      id: 2620,
      relationships: {
        rel1ToCamelize: {
          data: [
            {
              id: 4,
              type: 'type1ToCamelize',
            },
          ],
        },
      },
    },
  },
};

In my point of view this should work by this way:

result = normalize(json, {
    camelizeKeys: true,
    camelizeTypeValues: true,
});

And camelizeTypeValues should be in false state by default.

This is breaking change

Thank you for the help 😃

I agree that consistency is important. And additionally there could be case when you need to compare type value with the resources stored in your local repository by their type key. And since they are both camelized by default this will be easier then.
