The article from the RapidAPI blog discusses the challenges of optimizing search engine optimization (SEO) for Single Page Applications (SPAs) and introduces an isomorphic JavaScript solution to address these challenges. SPAs, which allow for dynamic, fast-loading applications like Gmail and Facebook, face difficulties with SEO because search engines like Google struggle to index pages that initially load without content and then request data. The proposed solution involves using an isomorphic hybrid approach, combining the classic server-rendered page with SPA features, where the server delivers a fully rendered HTML page initially, and subsequent data is retrieved as JSON for client-side rendering. This method, while effective, is acknowledged to be somewhat cumbersome, involving libraries such as React-DOM and React-Router to manage the process. The article concludes by suggesting that while this approach works, there is hope for a more streamlined process to be developed in the future.
