Since the Timer object is a global object, we need not require() anything in our code when working with the setTimeOut() function.
This module provides various methods that we can use to schedule functions to be called after some specified time. This method is used to schedule the execution of code after a given period in milliseconds. The setTimeOut() function is provided under the Timers module. By default, when a timer is scheduled using either setTimeout() or setInterval(), the Node.js event loop will continue running as long as the timer is active. In this section, we will look at the Node.js setTimeout() method. But if the user clicks on the Stop Timer button, then the setTimeout () will be cancelled.
In this example, the message will appear after a 10 second (10,000 millisecond) delay. Inside the method you have to reference the timeoutID. Scheduling timers using setTimeout() methodĪs discussed earlier, Node.js API provides utilities, which enable us to execute code at a later time based on our requirements. clearTimeout () This method is used to cancel a setTimeout (). In this tutorial, we use v15.12.Īt the end of this tutorial, you should be able to control the execution of some blocks of your code. Like the master process and a number of worker process concepts in Nginx, Node. It is highly inspired by the high concurrency model design of the Nginx web server. For browsers, timers are described in the timers section of HTML5 standard. Node.js is an asynchronous, non-blocking, and event-driven architecture. There are times when you want your code to run after some time. Again, there is no universal specification for these methods, so that’s fine. Node.js Timers Module: setTimeout, setInterval, setImmediate. For instance, Node.js returns a timer object with additional methods. Have Node.js installed in your development environment. In other environments, this can be something else.To follow this tutorial along, the reader should have the following: In this tutorial, we will look at the Node.js timer module and how we can use this utility to control the execution of code. The methods are globally accessible to provide conformity with the JavaScript browser API. Unlike most Node.js modules, the timer module is not imported. setTimeout is a built-in Node.js API function which executes a given method only after a desired time period which should be defined in milliseconds only and it returns a timeout object which can be used further in the process. This tutorial is on Node.js and I am going to discuss. Node.js has several utilities that we can use to schedule the execution of our code. The following article provides an outline for Node.js setTimeout. For example, using a timer, we can repeat the execution of a single code block at specific time intervals.
