Which page routes require lazy loading?

Page routing that requires lazy loading includes homepages, dynamically loaded pages, long list pages, content in pop-up windows or modal boxes, and pages that require user interaction. Detailed introduction: 1. The homepage is usually the first page when users visit the website, and it is also the user’s first impression of the website. Since the homepage usually contains a large amount of content and functions, such as carousels, navigation bars, recommended content, etc., If all content is loaded at once, the initial loading time will be too long; 2. Dynamically loaded pages. Dynamically loaded pages are usually based on the user's selection or input after the user performs certain operations.

With the development of front-end development, web applications are becoming more and more complex and large. In order to improve user experience and application performance, lazy loading has become a common technical method. Lazy loading can delay loading part or all of the content of the page, loading it only when the user needs to access it, thereby reducing initial loading time and resource consumption. In this article, we will discuss which page routes require lazy loading.

1. Home page: The home page is usually the first page when users visit the website, and it is also the user’s first impression of the website. Since the homepage usually contains a large amount of content and functions, such as carousels, navigation bars, recommended content, etc., loading all the content at once will cause the initial loading time to be too long. Therefore, lazily loading part or all of the content on the homepage can significantly improve the user experience.

2. Dynamically loaded pages: Dynamically loaded pages are usually dynamically generated based on the user's selection or input after the user performs certain operations. For example, search results page, product list page, etc. Since the content of these pages is dynamically generated based on the user's needs, only the necessary content is loaded on the initial load, and the rest can be loaded lazily.

3. Long list page: Long list page usually contains a large amount of data, such as news list, comment list, etc. Because these pages have a lot of content, loading them all at once can result in long initial load times. Therefore, you can use lazy loading to only load the currently visible part of the content, and then load more content when the user scrolls the page to the bottom, thereby improving the loading speed and performance of the page.

4. Contents in pop-up windows or modal boxes: Pop-up windows or modal boxes usually pop up after the user performs certain operations, such as login pop-ups, image zoom browsing, etc. Since the content of a pop-up window or modal box is usually dynamically generated, its content can be lazy loaded and loaded only when the pop-up window or modal box is displayed, thereby reducing the initial loading time.

5. Pages that require user interaction: Some pages require user interaction before content can be displayed, for example, personal information pages that are displayed only after the user performs a certain operation. Since the content of these pages is dynamically generated based on user operations, their content can be lazy loaded and loaded only after the user performs operations to improve the loading speed and performance of the page.

In summary, page routing that requires lazy loading includes homepages, dynamically loaded pages, long list pages, content in pop-up windows or modal boxes, and pages that require user interaction. Through lazy loading, the loading speed and performance of the page can be improved, and the user experience can be improved. Of course, in actual development, which page routes to lazily load need to be determined based on specific application scenarios and needs.
