Partial hydration is a technique in web development that allows certain parts of a web page to be “hydrated” or interactive, while other parts remain static. In other words, it’s a way to make only certain parts of a web page dynamic, while the rest remains static. This can help improve the performance of web pages by reducing the amount of JavaScript that needs to be executed on the client side.
Astro.build uses partial hydration to make web pages faster and more performant.
This allows the web page to load faster, as the browser only needs to execute the JavaScript for the visible parts of the page. As the user scrolls down, more parts of the page become visible, and Astro.build hydrate them as well.
Partial hydration can also help improve the user experience by providing a faster and more seamless navigation. Since only the visible parts of the page are hydrated, the page can respond more quickly to user interactions.
In summary, partial hydration is a technique that allows only certain parts of a web page to be interactive, which can help improve performance and user experience. Astro.build makes use of this technique by hydrating only the visible parts of a web page, which can help make web pages faster and more performant.
