FlushReload

FlushReload is a technique used in web development to improve the perceived performance of web pages, particularly in the context of modern Single Page Applications (SPAs). It addresses a common user experience issue where navigating between different views or sections of an application can lead to a noticeable delay or a blank screen while new content is fetched and rendered. FlushReload aims to mitigate this by pre-emptively loading resources and preparing the user interface.

The core idea behind FlushReload is to detect user intent to navigate to another part of the application before the user explicitly clicks a link or button. This intent detection can be based on various heuristics, such as the user's mouse cursor hovering over a link for a certain duration or their mouse movement indicating a potential click. Once intent is detected, FlushReload triggers the asynchronous loading of the necessary data and code for the target view in the background.

When the user eventually completes their navigation action, the requested content is either already available in the browser's cache or has been fetched and is ready to be displayed almost instantly. This minimizes the perceived loading time, creating a smoother and more responsive user experience. FlushReload can be implemented using JavaScript and by leveraging browser APIs for resource prefetching and caching. The effectiveness of FlushReload depends on factors such as the complexity of the application, network conditions, and the accuracy of the intent detection mechanism.
