Developers often need to reconsider what users expectations are and how they can satisfy them. An approach to making the user experience more fluid and responsive on the web is the introduction of single page applications.
Unlike traditional dynamically served web pages, single page applications are rendered on the client devices, while the server is only responsible for providing the static templates and the requested data. This method allows for snappier user interactions and faster page loads. Single page apps feel more like a native app, since they allow changing the content without reloading the browser. Additionally, they can make the first user interaction happen sooner from visiting the page, which helps to avoid losing customers due to slow page loads.
For users, single page applications are a breeze to use and feel very convenient. For developers, however, they used to pose several problems. First of all, managing many components in the user browser meant dealing with a lot of state changes. Furthermore, because the content was rendered in the user browser, opting for a single page application took its toll on search engine optimization. That is due to Google and other bots not being very good at caching dynamic pages.
From Transition to Reconciliation
The most amazing feature of React is that it ends the hassle of managing state transitions altogether. Instead, components defined in React are rendered again each time they change. I know, it sounds like a waste. But the React solution is actually pretty clever and performs incredibly well.
Even better, almost all code that runs on the client side can run on the server, too. This allows developers to make sure Google bots are served pages that they can index properly. Therefore, SEO problems can be avoided easily.
In our experience, React allows for a shorter development cycle, faster page loads. In addition, it provides a better user experience without sacrificing good SEO scores.
