[Javascript] Problems on deserialize text type and on file response

Hi,
I'm testing my api on the generated nodejs(javascript) client. I've found two problems, that break the client when called.
First:
when I've a call that return text/plain, SuperAgent initialize the body to {}, so data it's never null and doesn't verify the if condition, and in the end it gives an error.

I've done a fix for my case, just adding this line in the if clauses
"if (data == null || (returnType==='String' && Object.keys(data).length === 0 && data.constructor === Object))" but I think this is a bug and has to be correct

Second:
I've a call where the response is a file

And this is fine on other language like java or ruby, but not on javascript. It gives this error:

Thanks in advance for support

I'm using Swagger-codegen version 2.2.0

@donFotter I think you're correct in saying that the Javascript API client does not support plain text response or binary data response at the moment.

May I know if you've cycle to contribute a fix to address the issue?

Here is a good starting point: https://github.com/swagger-api/swagger-codegen/blob/master/modules/swagger-codegen/src/main/resources/Javascript/ApiClient.mustache#L297

I'm sorry, but I'm really in trouble with the development of the new api which I'm working on.
As posted before, I've made an own solution(changing the if clause). If this could help, consider this my contribution

@donFotter that's ok. Thanks again for sharing the fix.

We'll see if someone from the community has cycle to contribute a fix.
