How to get JSON object on client-side

I'm currently attempting to send a JSON object from the server to the client but I'm not sure if I'm accessing it correctly.

app.post('/url', function(request, response){
....
var result = fuse.search(); 

response.json(result); // results should be sent back as a response

} )

$.post("/url", options, function(response, request) {
    var json = response.json;    
)
