returning data from server to an ajax request sent in client side javascript

Question

• Node.js web server
• Request handler in web server

app.get('/documents/:id.:format?', function(req, res) {
   **dataTobeSentToClientSideJavaScript** = processRequest (req);
   ... 
})

• ajax request from client side javascript

  var request = $.ajax({
  url: "/documents/xxx",
  });
  request.done(handleResponse);
  

• I am able to receive the request on server side

What code should be written on server side so that I can populate the "handleRespone" object expected in my ajax request above with dataTobeSentToClientSideJavaScript created on server side?

Answer 1

You want to use methods exposed by the response object such as res.write, res.end or res.json

take a look at http://nodejs.org/api/http.html#http_class_http_serverresponse (Node.js API)

and since you're using Express - http://expressjs.com/api.html#res.status
