Hydration enables interactivity by attaching JavaScript to server-rendered HTML content.
Hydration refers to the process in which a client-side JavaScript framework takes over the HTML content that was initially rendered on the server. This process allows interactivity on static content, enabling developers to create rich user experiences.
During hydration, the JavaScript framework attaches event listeners and makes the page interactive. This is critical for frameworks like React and Vue. Proper hydration ensures that the content is not only visible to users but also indexable by search engines.
For SEO, proper hydration ensures that search engines can index interactive content effectively. If hydration is not implemented correctly, it may lead to issues where search engines see only static content without the intended functionality.
For example, a news website may render articles on the server for fast loading. When the user accesses the page, hydration occurs, allowing features like comments and likes to function seamlessly.
