In this session the API-First Initiative maintainers will dress in the pink t-shirt to explain why we have decided to push hard on the inclusion into core of the JSON:API module. After you attend the session you will know: Why we focused our efforts on JSON:API as opposed to new feature development in the REST module, GraphQL, Relaxed WS, etc. What are the high level goals that JSON:API meets. What are the remaining goals that JSON:API has? What lessons did we learn? What challenges did we face? What's the future of decoupled Drupal (hypermedia, node.js, translations, and more)? Why do we want JSON:API in core and not simply a popular contrib à la Views in D7? Why sharing your experiences with the JSON:API module is as valuable as your patches. We hope this session will be informative and conversational. As usual, we will bring candy and healthy snacks in exchange for your thoughts.
