Overview:
The Next Lazy Hydration on Scroll is designed for developers aiming to optimize their Next.js applications’ performance. By focusing on lazy loading and hydrating components only when they enter the user’s viewport, this tool significantly enhances the overall responsiveness and efficiency of web applications. This innovative approach helps reduce Total Blocking Time (TBT) and ensures a smoother user experience while keeping bundle sizes smaller.
This feature is particularly beneficial for projects using Next.js 12 and above, as it leverages built-in capabilities to enable server-rendered content while avoiding unnecessary loading of JavaScript until a user scrolls to a component. This becomes crucial in maintaining a balance between functionality and performance, ultimately improving page load times and user engagement without compromising SEO.
Features:
- Lower Total Blocking Time (TBT): Reduces the time scripts block user interactions, leading to a more seamless experience.
- Smaller Bundle Size: Efficiently lazy loads components, decreasing the amount of code that needs to be downloaded upfront.
- Improved Performance: Speedy loading of interactive elements once they come into the user’s view boosts responsiveness.
- Customizable Wrapper Elements: Allows developers to specify any HTML element for wrapping components, providing flexibility in design and structure.
- SEO Friendly: Ensures all content is pre-rendered, making it easily accessible and indexable by search engines.
- Browser Support: Compatible with all modern browsers, including IE11 with a polyfill, ensuring broad accessibility.
- Server Rendering: Initially serves complete HTML to users, enabling them to see content instantly before JavaScript loads.
- Usage of IntersectionObserver: Tracks component visibility in a performance-efficient manner, only triggering hydration when necessary.
