Effortlessly make your lazy loading archive website that reflects your brand

Make sure to document and test your code thoroughly and ensure that the initialization logic and parameters are clear and consistent. Additionally, avoid using lazy initialization for objects or values that have side effects or dependencies, which could affect the state or behavior of other objects or values.

The @Lazy annotation is particularly useful in scenarios where: The bean is resource-intensive to create. The bean is rarely used during the applicationʼs lifetime. The application has many beans, and eager initialization can cause startup performance issues.

Instead of loading everything immediately when a user visits a page, lazy loading prioritizes critical content first and defers secondary resources until the user scrolls to them or interacts with them. Lazy loading is commonly used for: Images: Deferring off-screen images until they are about to be viewed.

A practical example would be when you land on the home page of an e-commerce site with a link to a cart page/section, and none of the cart pageʼs resources (such as JavaScript, CSS, and images) are downloaded until you navigate there.

Use cases for @Lazy. Using the @Lazy annotation in Spring can be beneficial in various scenarios, especially when you want to optimize the startup performance of your application by deferring the initialization of certain beans until they are actually needed.

Native lazy loading of images and iframes is a straightforward method to lazy load content when a user scrolls the web page. You just need to add the loading=lazy attribute to your images and iframes. As you can see, no JavaScript, no dynamic swapping of the src attributeʼs value, just plain old HTML.

Lazy initialization of an object means that its creation is deferred until it is first used. (For this topic, the terms lazy initialization and lazy instantiation are synonymous.) Lazy initialization is primarily used to improve performance, avoid wasteful computation, and reduce program memory requirements.

Lazy loading can harm SEO if it prevents Googlebot from crawling content, especially important elements like text and images. Google can now handle lazy-loaded content, but only if itʼs implemented with proper techniques like using loading=``lazyʼʼ or IntersectionObserver.
