DOM stands for ‘Documents Object Model’. It’s the World Wide Web Consortium's fundamental logical homepage model. Every time the UI state of an application changes, the DOM is updated to reflect the change. Whenever the application user interface is updated, the DOM is rendered which ultimately impacts the application performance, resulting in slower loading. The complexity of the DOM and the numerous UI components further depletes the performance because each change necessitates a new rendering of the page. However, the virtual DOM concept in React has changed everything. Let’s see below − What is DOM? To put it another way, ... Read More

Client−side rendering is a technique used in web development to improve the performance of web pages. It moves the browser’s rendering process from the server to the client. This way, there is no need for a round−trip request to render a page. Let's start by discussing what occurs when your program requires client−side rendering. React applications are developed by calling one or several JavaScript modules from a simple HTML document while utilizing only the CLI or React command create−react−app. The HTML of each page is created and loaded into the website by JavaScript, which automatically adds it to the document's ...

Single Page Applications or SPAs are beginning to rule the IT marketplace now. (And for good reasons!) They are incredibly fast and render an amazing user experience. But what makes them faster? Well, the reason is that the SPAs enable the users to navigate through several pages without having to refresh the page. As the single page applications dynamically rewrite the web page content from the server, they do not load the entire web page after every render. This way, the web pages potentially improvise the performance by creating a more dynamic user experience. Let’s learn about the ... Read More

Server−side rendering has been around for a while now. It was first introduced in the early 2000s and has been used by many websites since then. The idea behind this technique is to pre−render HTML pages on a server and send them back to the client's browser as they request them. With server-side rendering (SSR), the page is rendered on the server. This ensures that the page is available to users even before it loads on their browser. We’ll get to know more about SSR in this article − How Server-side Rendering (SSR) Works? It is the process of rendering ... Read More
