Node.js / express: respond immediately to client request and continue tasks in nextTick

Question

I would like to separate server high consuming CPU task from user experience:

./main.js:

var express = require(\'express\');
var Test = require(\'./resou         


        

Answer 1

Thakns for Peter Lyons help, finally the main problem was firefox buffer: response was not so long as to flush it (so firefox kept waiting).

Anyway, for hight CPU performing tasks, node would keep hanged until finishing, so will not be attending new requests. If someone needs it, it can be achieved by forking (with child_process, see sample in http://nodejs.org/api/child_process.html)

Have to say that change of context by forking could take longer than splitting the task in different ticks.

./resources/test.js:

var child = require('child_process');
function Test() {}
module.exports = Test;

Test.testAsync = function(req, res) {
  res.send(200, "Hello world, this should be sent inmediately");
  var childTask = child.fork('child.js');
  childTask.send({ hello: 'world' });
};

./resources/child.js:

process.on('message', function(m) {
  console.log('CHILD got message:', m);
});
