Sending raw data is impossible.

[reflog]

Hi!
Thanks for an awesome project! It make writing services in TS a real pleasure.
One bug I came across - even for actions that are marked with a different @ContentType and not inside @jsoncontroller - the result cannot be binary, for example, I cannot send image file.
The reason for it is the following code in ExpressDriver:

 } else {
                    response.send(String(result));
                }

Basically, even if a Buffer is returned - it's converted to string. It's not a correct behavior. At least some sort of escape hatch is needed.

What would you recommend?

I had to return images. Easiest thing is use @res() to inject response object and write directly through it

@awaragi - do you have a code snippet to demonstrate, maybe? because when I injected @res and tried to set content type I got an error of 'cannot change headers after they are sent'.

[awaragi]

@Get(":I'd") get(@Param("id") id: string, @Res() response: any) {
    return this.documentDAO.get(id).then((data) => {
        if (data) {
            response.append("Content-Type", data.mimeType);
            response.end(data.file.buffer, 'UTF-8');
        } else {
            response.status(404);
            // 404 handler will take care of message content
        }
    }).catch((error) => {
        response.status(500);
        return Status.failure(error.message);
    })
}

this should be fixed in 0.7.0
