Bring your ideas to life with Instapage's lazy loading directory listing page template

Lazy loading makes querying navigational data implicit, fetching data from the database when its accessed. The downside is that this may result in running too many queries due to the N+1 problem. Explicit loading is similar, in that related data is only loaded when you need it.

Lazy loading should not be used for critical or essential resources that are required for the basic functionality of an application. This includes core libraries, frameworks, or modules, as well as important user interface elements such as navigation menus or search bars.

Full page view (Stitching issues) When there is no specific width and height given to lazy loaded elements, during scrolling these elements height will change ing to DOM. This cascades other elements to go further down the DOM, and also increases the DOMs height as well.

Chrome and Firefox both support lazy loading with the loading attribute. This attribute can be added to elements, and also to elements. A value of lazy tells the browser to load the image immediately if it is in the viewport, and to fetch other images when the user scrolls near them.

If you have used lazy loading unnecessary in your application, it can cause content buffering. This happens when the users scroll down fast while the resources are still downloading. This situation can occur especially for slow bandwidth connections, and it will impact the speed of webpage rendering.

For example, if a web page has an image that the user has to scroll down to see, you can display a placeholder and lazy load the full image only when the user arrives to its location.

What are the disadvantages of lazy loading? Users may request resources faster than expected: For instance, if a user scrolls quickly down a page, they might have to wait for the images to load. This could negatively impact user experience.

1 What is pagination and lazy loading? Pagination is the process of dividing a large data set into smaller chunks or pages that can be accessed sequentially or randomly. Lazy loading is the technique of loading data only when it is required, rather than loading all the data at once.
