Strapi version 4 introduces a streamlined process for generating URL slugs using its new UID field type, significantly simplifying the task compared to version 3, where manual coding was necessary. This feature allows users to automatically generate unique identifiers from existing content fields, enhancing search engine optimization (SEO) and user readability of URLs without requiring code intervention. The process involves using the Content-Type Builder in the Strapi Admin Panel to create new content types and configure slug fields, making it easier to manage slugs directly within the platform. For users new to Strapi, familiarizing themselves with the Strapi Admin Panel and documentation is recommended, and the installation of version 4 can be initiated with a simple command. Chris, the author, emphasizes the ease and efficiency of the new system in improving content accessibility and SEO with minimal technical intervention.
