Is there a way of stopping a function after a delay? Nodejs

settimeout nodejs
nodejs cluster
nodejs sleep
javascript sleep

Is it possible to abort a function after a delay? Something like:

function f() {
    //Do some process here
}

after(10000).stop(f)

Any idea about how to do that? Thank you.

Try cluster module like this

const cluster = require('cluster');

if (cluster.isMaster) {
    const fn = cluster.fork();
    setTimeout(_=>fn.process.kill(), 300);
} else {
    for(;;) {
       process.stdout.write('#');
    }
}

How can I wait In Node.js (JavaScript)? l need to pause for a period , Best way to do this is to break your code into multiple functions, like this: Put the code that you want executed after the delay within the setTimeout callback: The Node.js API provides several ways of scheduling code to execute at some point after the present moment. The functions below may seem familiar, since they are available in most browsers, but Node.js actually provides its own implementation of these methods.

You could wrap your function inside a function that checks for the time.

function stopExecutingAfter(timeout, fn) {
  var stopifAfter = Date.now() + timeout
  return function() {
    if(Date.now() > stopIfAfter) return
    fn.apply(null, arguments)
  }
}

Timers in Node.js, The Timers module in Node.js contains functions that execute code after a set since all the methods are available globally to emulate the browser JavaScript API. a function to execute as its first argument and the millisecond delay defined as nextTick() , the execution cannot be stopped, just like with a normal function. One additional question: this function delays every incoming message, but is there a way to ignore any additional messages received during the delay period? Example: an inject node fires a timestamp once per second, the function delays the first incoming timestamp by 5 seconds, and the 4 additional timestamps received during the first delay

So we will have library killer.js

const cluster = require('cluster');

module.exports = (fn, delay) => {
    if (cluster.isMaster) {
        const fn = cluster.fork();
        setTimeout(_=>fn.process.kill(), delay);
    } else {
        fn();
    }
}

And example for using it

const killer = require('./killer');

function fn() {
    for(;;) process.stdout.write('#');
}

killer(fn, 100);

Timers, The timer functions within Node.js implement a similar API as the timers API When called, requests that the Node.js event loop not exit so long as the Immediate is active. Schedules execution of a one-time callback after delay milliseconds. The The setImmediate() , setInterval() , and setTimeout() methods each return  Typing .exit in nodejs REPL. Pressing <ctrl>-C twice. pressing <ctrl>-D. process.exit(0) meaning a natural exit from REPL. If you want to return any other status you can return a non zero number. process.kill(process.pid) is the way to kill using nodejs api from within your code or from REPL.

Delay, Sleep, Pause, & Wait in JavaScript, James Hibbard explains the pitfalls of implementing a sleep function The standard way of creating a delay in JavaScript is to use its setTimeout method. This would log “Hello” to the console, then after two seconds “World! Stack Overflow Public Is there a way to stop execution of next function of series with async in nodejs? will stop the execution of your series and call async

Scheduling: setTimeout and setInterval, setTimeout allows us to run a function once after the interval of time. For instance, Node.js returns a timer object with additional methods. executes longer than delay ms, then the calls will happen without a pause at all. Many programming languages have a sleep function that will delay a program’s execution for a given number of seconds. This functionality is absent from JavaScript, however, owing to its

Node.js Recipes: A Problem-Solution Approach, setTimeout is a way that you can schedule a one-time event after a given time It functions in a similar manner by providing a mechanism to delay execution of a The unref() method allows the Node.js process to terminate if the timer is the  User Story: As a Roblox developer, it is currently too messy to implement a cancellable delay. Use Case: Take this case study as an example. We needed to interrupt the user’s sprint if they were sprinting for too long (exploiting or high latency), and we needed to start to regenerate their stamina one second after they had stopped sprinting. The implementation of that functionality required
