Granted I blazed through the docs and am not a node expert, but for a streaming web framework I could not find a reference to streaming responses. It is very Rackish, all examples I found point to calling callback(200, {}, "Hello world!");
What I don't get, is you have to fight with Rack to get anything close to async, yet here comes a web framework for an async environment modeled after Rack, go figure.
I assume (meaning I'm about to make an ass out of u & an ass out of me) the answer is to pass a stream in place of the "Hello world!" string, but that would cause hell with any middleware expecting a completed response.
The Strata spec states that a body may be either a string or a stream. All Strata middleware that needs to modify the body in some way must account for this. It's not difficult to do a "if (typeof body == 'string')".
Strata borrows many concepts from Rack, but not the synchronous part. Instead of expecting your app to return something, Strata gives you a callback that you can use to serve the response when you're ready.
I admit the manual could probably give a better example of streaming a response. For now, check out the static file serving middleware (https://github.com/mjijackson/strata/tree/master/lib/static....). You'll see that the response body is simply a readable stream to the file on disk.
