Sleep In NodeJS - Onlinecode

Sleep in NodeJS – onlinecode

In this post, we will give you information about Sleep in NodeJS – onlinecode. Here we will give you detail about Sleep in NodeJS – onlinecode And how to use it also give you a demo for it if it is necessary.

One way to delay execution of a function in NodeJS is to use the seTimeout() function.
Just put the code you want to delay in the callback.
For example, below is how you can wait 1 second before executing some code.

setTimeout(function() {
  console.log('This printed after about 1 second');
}, 1000);

Using async/await

You can use async/await with promises to delay execution without callbacks.

function delay(time) {
  return new Promise(resolve => setTimeout(resolve, time));
} 

run();

async function run() {
  await delay(1000);
  console.log('This printed after about 1 second');
}

Using the Sleep Command

You can use execSync to invoke your OS’ sleep command.

const {execSync} = require('child_process');

execSync('sleep 1'); // block process for 1 second.

This is different from using the delay(time) function from the previous examples because delay(time) is still non-blocking.
For example, you can run multiple delay() calls in parallel using Promise.all()

async function run() {
  const start = Date.now();
  await Promise.all([delay(1000), delay(1000)]);
  // Prints about 1000, because the 'delay()' calls run in parallel
  console.log('Elapsed:', Date.now() - start);
}

function delay(time) {
  return new Promise(resolve => setTimeout(resolve, time));
}

run();

However, with execSync, you cannot run multiple execSync('sleep 1') in parallel.
execSync() blocks the entire Node process, meaning no other code can execute.
Be careful about using execSync()!

const {execSync} = require('child_process');

const start = Date.now();
execSync('sleep 1');
execSync('sleep 1');
// Prints about 2000, because 'execSync()' runs in series
console.log('Elapsed:', Date.now() - start);

Node.js is an open-source, cross-platform JavaScript runtime environment. Node.js allows you to run JavaScript code outside of a web browser. This makes it possible to create a wide variety of applications, including web servers, real-time chat applications, and data processing pipelines.

Node.js is built on top of the V8 JavaScript engine, which is also used by Google Chrome. This means that Node.js applications can take advantage of the same performance and features as Chrome.

Node.js is a popular choice for building web servers. This is because Node.js is very efficient at handling concurrent requests. Node.js uses a non-blocking event loop to handle requests, which means that it can handle multiple requests at the same time without slowing down.

Node.js is also a good choice for building real-time chat applications. This is because Node.js is able to push data to clients in real time without the need for polling. This makes it possible to create a smooth and responsive user experience.

Node.js is a powerful tool that can be used to create a wide variety of applications. If you are looking for a JavaScript runtime environment that is fast, scalable, and efficient, then Node.js is a great choice.

Here are some of the benefits of using Node.js:

Performance: Node.js is very efficient at handling concurrent requests. This makes it a good choice for building web servers and real-time chat applications.
Scalability: Node.js is designed to scale horizontally. This means that you can add more nodes to your cluster to handle more traffic.
Efficiency: Node.js uses a non-blocking event loop to handle requests. This makes it possible to handle multiple requests at the same time without slowing down.
Community: Node.js has a large and active community. This means that there are many resources available to help you learn and use Node.js.
