The rapid development of the digital world and the increasing number of online businesses dictate the need for constant evolution and improvement of existing technologies for web application development. Starting from improved performance, scalability capabilities, improved user experience and SEO optimization, technologies are constantly evolving, adding new and new functionalities as a solution to existing problems and limitations.

Recently, NextJS has been added to the list of technologies rcs data philippines skyrocketing growth and popularity, and the number of developers including it in the technology stack on which they build their projects is increasing.


But what does NextJS actually represent?
NextJS is a framework built on top of ReactJS and is used to build Single Page applications. It was developed by the Vercel team. The popularity of NextJS is mainly based on the fact that it solved a big problem that developers had with applications that are served on the client side, in a web browser. Yes, although those applications have an advanced user experience where there is no need to reload the page when using the application, they also have their own problems.

Namely, because much of the content becomes available only after the browser executes the code, web crawlers have difficulty reading the content of that page. As a result, many Single Page Applications, while popular, remain anonymous to search engines like Google.

NextJS solves this problem by rendering React components on the server side (SSR). With NextJS, developers can render the code on the server side and send a simple, indexable HTML file to the client (web browser). While this was not entirely impossible before the advent of NextJS, it required a very long and complicated process to make it possible.
