The trend of creating single page applications (SPAs) and progressive web applications (PWAs) is gradually gaining more and more momentum in the web industry. This is justified by a number of advantages, including relatively simple development, high speed and convenience for users, as well as new opportunities for business development. In this article, we'll look at the key components of SPAs and PWAs, their differences, and how to make these sites as SEO-friendly as possible. 1. What are SPA and PWA SPA (Single Page Application) is a one-page web application that loads on a single HTML page and does not require reloading due to dynamic updates using AJAX. The work of the SPA is done inside the browser, and the code rendering takes place on the user's side.
Popular examples of dynamic sites are Gmail, Google Maps, Facebook, Meduza. When you go C Level Executive List to them, you are first presented with the main content, and to perform various actions (scrolling, switching to other pages), instead of reloading the pages, only individual elements are loaded. Advantages of single-page applications include the following aspects: high speed compared to traditional sites; well-established work on both desktop and mobile devices; flexibility and responsiveness due to the absence of reloading and re-rendering; optimized and simplified development. Disadvantages: increased load on the browser; lack of JS can be a problem for many functions; the need to ensure good data protection - through cross-site scripting (XSS), attackers can gain access to the code and add scripts on the client side.
PWA (Progressive Web Apps) is a site built on web technologies using JavaScript, HTML and CSS, which interacts with the visitor as an application. It can be added to the home screen of mobile devices and send push notifications. Due to access to the hardware of the device, PWA works without an Internet connection. A good example of a PWA site is Google Docs, which is known as an online office, but the user can interact with it offline. Advantages of PWA sites: ease of development: creating a PWA is not the creation of a separate site, but a minimal change to an existing one; instant installation; cross-platform; minimum requirements for device resources; fast loading online and offline thanks to page caching; faster speed compared to native applications.
