Hi HN,<p>I'm Tony with Cosmic. I built this Cosmic Message App (<a href="https://github.com/cosmicjs/cosmic-message-app">https://github.com/cosmicjs/cosmic-message-app</a>) to show how to use Next.js, React Server Actions, and Cosmic CMS to build a simple app to add text and upload media to a message feed. All without exposing any API keys to the client.<p>I found the development process pretty straightforward using Next.js, Cosmic JavaScript SDK, File Upload Block, and React Server Actions.<p>Overall I'm optimistic about this stack to make building user generated content apps like this, much easier.<p>Let me know what you think in the comments.<p>Tony
