Are there any rules for building the architecture of a node.js application? For example, is it correct to pass a reponse object in a callback function?

Question

Software design

For example:

app.post('/authorize',function(req, res){
    pg_queries.authorize(res); 
});

Passing response to a function in the request processing module

pg_queries.authorize = function (response) {
 if (...) {
 res.send(session-key); //используем переданный объект
}
};

Is it possible to somehow send a response to the user without violating the principle of asynchrony?
