A Single Page Application (SPA) website utilizes Client-Side Rendering (CSR) to render its content.
Upon initial loading, the server only returns the root component, and subsequent data is fetched through API interactions.
However, for web crawlers responsible for ranking websites, the content obtained during crawling may appear empty.
While Google claims that their crawler executes JavaScript, other search engines may not necessarily do so.
To address this issue, a Prerender service is employed to achieve pre-rendering for web crawlers, optimizing search results.
