Socket.io is a popular JavaScript library that allows us to communicate between the server and the client. We can create an instance of socket.io on the client and server sides and listen to or emit the events from both sides. Also, we can listen to the event emitted from the server on multiple web clients. In real-time, we can use the socket.io library to create chat applications and online games requiring bi-direction communication. For example, if you have observed while playing chess or Ludo, it allows us to talk with our opponent. In this tutorial, we will learn to configure ... Read More

Introduction: What is Docker and Why Use it for Node.js? Docker is a containerization platform that lets you package your apps and dependencies into a self-contained environment. This means you can run your application in several environments without worrying about dependencies or setup difficulties. Utilizing Docker with Node.js can bring numerous advantages, particularly during the development and deployment stages of your project. You can use Docker to generate a Docker image of your Node.js application that includes all of the dependencies and configurations needed to run it. This image can then be readily distributed to additional developers or deployed ... Read More

JavaScript is a scripting language which is used to develop HTML pages that are interactive with users. It is usually run on web browsers. NodeJS is a platform or runtime environment using which we can run JavaScript in a system rather than a browser. What is JavaScript? JavaScript is a front-end programming language used in web development. It is a lightweight object oriented scripting language that make the web page dynamic and interactive with users. HTML creates website (structure layer), CSS makes it more attractive (design layer) and JavaScript allows the users to interact with these websites rather than simply ... Read More

What is Node.js? Node.js is a JavaScript runtime environment which is used to execute the JavaScript code outside the browser. It can be used on different operating system like windows, Mac OS, Linux. Node.js is used to build server-side web applications which can respond fast and handle multiple connections parallelly. Why Node.js? JavaScript was created for the purpose of using it in web browsers. Node.js has enabled developers to use JavaScript for full-stack development. It allows developers to write both the client-side and server-side code in the same language and create web applications, command-line interface tools and other software. Using ... Read More

When it comes to choosing the right language for a project, developers often compare different programming languages to find the best fit. In this article, we will compare two popular programming languages, Go and Node.js, to help you make an informed decision. Comparison between Go & Node.js Go and Node.js are both open-source, server-side programming languages. Go was developed by Google in 2009, while Node.js was developed by Ryan Dahl in 2009. Both languages have gained a lot of popularity in recent years, and they are often used for similar tasks, such as building web applications and APIs. ... Read More

The cookies are the data stored in the user’s browser for quick access. For example, whenever we log in to any website, the server returns the access token, which can be stored in the browser’s cookie with the expiry time. So, whenever a user revisits the website, they don’t need to log in to the website repeatedly if the access token stored in the cookies has not expired. We can also access the browser’s cookies on the server side in NodeJS. After that, we can check if any detailed data exists in the cookies we are looking at, and if ... Read More

What is Node.js? Ryan Dahl developed Node.js in 2009 and its current version is v0.10.36. Node.js is a server-side platform which is developed on the JavaScript Engine of Google Chrome. This is a cross-platform runtime environment which can be used to develop server-side and networking applications. JavaScript is used to create Node.js applications which can be executed on Node.js environment installed on various platforms like OSX, Linux, and Windows. Cost of Node.js Node.js is an open-source library and can be used for free. There are many hosting platforms that utilize Node.js. Some of them provide paid services. Why Node.js Alternatives? ...

There is a timer module in node.js that is used to schedule timers and carry out specific functions at a later time. In Node.js the JavaScript function clearTimeout() is used to halt the execution of the setTimeout() function by using the timeoutID returned by a specific setTimeout() function call. This function does nothing if the timeoutID didn't match for any prior calls or if an invalid value is given. The setTimeout() JavaScript function executes the specified code after the user-specified amount of time or delay, and it returns an ID, which is a positive integer commonly referred to as the ...

Sharing code between the backend and front end of a full-stack application can be a challenging task. However, it's essential for building maintainable and scalable applications. By sharing code, we can avoid code duplication, reduce development time, and maintain consistency across our applications. In this tutorial, we'll explore different techniques for sharing code between Node.js and the browser and learn how to choose the best approach for our project. Techniques for Sharing Code Between Node.js and the Browser Users can follow the approaches below to share code between node.js and the browser − CommonJS Modules CommonJS modules are ... Read More

In Node.js, a built-in sort() method is available to sort an array without a headache. However, as a beginner to learn how the sort() method works internally, users should learn various sorting algorithms. In this tutorial, we will learn a different algorithm to sort an array without using loops in NodeJS. Use the setInterval() method The setInterval() method allows us to invoke any particular function after each interval. Also, we can store the id of the setInterval() method in any variable and use it later to clear the interval. So, we can call a callback function in the ... Read More
