Description: Server-side rendering (SSR) is the process by which web pages are generated on the server before being sent to the client’s browser. Unlike client-side rendering, where the browser is responsible for building the user interface from data and templates, SSR allows the server to process and deliver a fully rendered page. This means that the HTML content is generated on the server and sent to the client, which can result in faster load times and a better user experience, especially on resource-limited devices. Additionally, SSR can improve indexing by search engines, as the content is available at the time of the initial load. In the context of various web frameworks, SSR has become a popular technique for optimizing web applications, allowing developers to leverage the advantages of both worlds: client interactivity and server efficiency. This technique is particularly relevant in applications that require high performance and a smooth user experience, as well as in those looking to enhance their SEO.
History: The concept of server-side rendering dates back to the early days of the web when pages were fully generated on the server. However, with the advent of JavaScript and the development of more interactive web applications, the focus shifted towards client-side rendering. Starting in the 2010s, frameworks like Angular and React began to popularize SSR again, allowing developers to combine client interactivity with the benefits of server-side rendering.
Uses: Server-side rendering is primarily used in web applications that require optimal performance and good indexing in search engines. It is common in dynamic content sites, such as blogs and e-commerce platforms, where load time and search visibility are crucial. It is also employed in applications that need a smooth user experience from the outset, such as single-page applications (SPAs) looking to improve their SEO.
Examples: An example of server-side rendering is an e-commerce application built with Angular Universal, where product pages are generated on the server to improve load speed and search engine indexing. Another case is the use of various server-side frameworks to create APIs that render HTML content in response to client requests, thus optimizing the user experience.
