Sam tells Ryan about his experience setting up an in-browser code editor with CodeMirror that he plans on using for blog posts and code recipes, as well as what he thought about using Radix Themes for the first time in earnest on a side project of his currently styled with Tailwind.

Sam and Ryan talk about why it’s better to think of throw as a general-purpose JavaScript language feature rather than something that should only be used for error handling.

They also discuss

Sam and Ryan discuss the core values of the Next.js framework, and how those values motivate several of the framework’s design decisions. They talk about caching, why layouts don’t have access to the URL, and why the router doesn’t expose navigation events, as well as how developers should think about extending Next’s functionality with their own application code.

Sam talks to Ryan about refactoring an MDX blog post to a React Server Component. They discuss how RSC’s ability to render server-side content with “client-side holes” turns out to replace MDX for many uses cases. They also talk about other tools that are (surprisingly) a conceptual subset of the RSC architecture, such as custom Webpack loaders.

Sam and Ryan read and discuss the latest update from React Labs.

Sam and Ryan discuss the intuition behind React Transitions, and why React’s new useOptimistic hook is a good fit for building a URL-driven filter panel that stays fully responsive to client interactions.

Ryan and Sam discuss the purpose and usage of the useOptimistic() hook, a new experimental API from React.

Ryan and Sam discuss the purpose and usage of the cache() function, a new experimental API from React.

Sam and Ryan talk about Advanced Radix UI, Build UI’s newest course. They also read and discuss a blog post that describes the RSC architecture in terms of two processes: React Server and React Client.

Ian Landsman & Aaron Francis join Sam to discuss React Server Actions & Server Components, why it's important to have one set of opinions, and yes, the infamous SQL Injection Slide at NextConf. This is a crossover episode with the excellent podcast [Mostly Technical](https://mostlytechnical.com/).
