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

Try waiting instead of hogging the CPU:

res.send("Hello world, this should be sent inmediately");
console.log("Response sent.");
setTimeout(function() {
  console.log("After-response code running!");
}, 3000);

node.js is single-threaded. If you lock up the CPU with a busy loop, the whole thing grinds to a halt until that is done.
