server.timeout is perfectly working on local but on production not working in node js

Question

I want to set request timeout grater than default time in node js after creating server its working on local site but when it deployed its not working.Before all back-end execution it will send the error in response.My code like this

var express = require('express');

var app = express();

var http = require('http');

var server = http.createServer(app);

server.listen(port);

server.timeout = 900000;

Answer 1

Let's assume the logic in setTimeout will be running after every less than 30 minutes, so YES the heroku server will be still awake.

Will setTimeout use Heroku free dyno hours?
