Gatsby has introduced two new built-in APIs, the Script and Head APIs, which address the management of different types of scripts within the framework. The distinction between dynamic scripts and data block scripts is crucial, as defined by the HTML specification: dynamic scripts typically have a missing or JavaScript MIME type in their type attribute, while data block scripts have other types like application/ld+json. For optimal performance and functionality, dynamic scripts should be loaded using the Gatsby Script API within pages or components, as they load scripts in the browser runtime after hydration, enhancing performance without blocking. In contrast, data block scripts should be included using the regular `<script>` tag in the Gatsby Head, ensuring that static metadata is properly integrated into the document for search engines and users without causing performance issues. This approach ensures that both dynamic and static scripts are managed efficiently, making the most of Gatsby's capabilities for enhanced website performance.
