Question

How can I know the response time of a URL?

I’m using http.get() to make an HTTP GET request.

Answer 1

There’s no builtin function or value to get the response time.

But you can easily get the value yourself.

var http = require('http');
var start = new Date();
http.get({host: 'google.com', port: 80}, function(res) {
    console.log('Request took:', new Date() - start, 'ms');
});

EDIT

Since V8 also supports the new ES5 Date.now(), using that instead of new Date() would be a little bit cleaner.
