Plack::Middleware::JSONP

    enable "JSONP", callback_key => 'jsonp';

Plack::Middleware::JSONP wraps JSON response, which has Content-Type value either "text/javascript" or "application/json" as a JSONP response which is specified with the "callback" query parameter. The name of the parameter can be set while enabling the middleware.

This middleware only works with a non-streaming response, and doesn't touch the response otherwise.
