Sam and Ryan talk about React 19's useActionState hook. They discuss how adding async functions to a plain React app introduces lots of in-between states that developers must grapple with, and how useActionState allows React to collapse and eliminate these states, bringing the simplicity of React's sync mental model to our async code.
Timestamps:
- 0:00 - Intro
- 1:51 - How React normally eliminates state in synchronous apps
- 8:20 - How useActionState lets React eliminate state in asynchronous apps
- 18:17 - Why you shouldn't just pass server actions into useActionState
- 23:00 - TCP/IP and UDP analogy
- 26:39 - Thinking of useActionState like enqueue
- 34:55 - Why the term "reducer" is too loaded for best understanding useActionState
- 51:07 - How useActionState helps you build a Todo app that stays responsive during pending actions

Sam and Ryan talk about how frameworks and infrastructure evolve with each other, using Next.js as a representative example. They discuss how hosting providers like Heroku have always imposed certain constraints on apps, what features those constraints enable hosting providers to support, how burdensome those constraints are across different frameworks, and how frameworks that add infra-specific APIs can best communicate the costs of those APIs and benefits they enable.

Tom Occhino, Chief Product Officer at Vercel and former Engineering Director at Facebook, joins Sam to talk about the pivotal moments in React's history. He talks about how React popularized the ideas of declarative rendering and unidirectional data flow, how GraphQL furthered React's goal of co-locating all the concerns of a particular piece of UI, the problems that GraphQL led to at Facebook and how Relay solved them, and how Suspense, Server Components, and PPR are the generalized spiritual successors to the stack used at Facebook.

Sam and Ryan discuss controlled and uncontrolled components in React. They talk about how uncontrolled components can be thought of as components that manage their own internal state, why you should model your complex React components after the simpler APIs of native HTML elements like inputs, why you shouldn't try to make components that are both controlled and uncontrolled, and why making a new component boundary is sometimes all you need to make your custom components behave more predictably. Timestamps: 0:00 - Intro 1:41 - What are controlled and uncontrolled components? 6:11 - How to change a component from uncontrolled to controlled 8:48 - How do you decide when to use a controlled or uncontrolled component? 12:00 - Sortable table example and a single source of truth 15:27 - Is it always either controlled or uncontrolled? 21:09 - Color picker example and not exposing internal state 28:46 - Sortable list example with Framer Motion 39:45 - Component boundaries and wearing two hats: the library author vs. library consumer 41:43 - How do you know if you are using the wrong approach?

Sam and Ryan talk about the pattern of building unstyled components with React. They discuss why unstyled components were created, how they improve upon composition patterns from UI libraries like Bootstrap, how they can be used to share behavior and logic without prescribing any styling opinions, and how they fit into a larger collection of React patterns that can be used to build more powerful components that avoid premature abstractions. Timestamps: 0:00 - Intro 1:36 - What are unstyled components? 2:24 - How do unstyled components improve upon earlier patterns? 6:44 - Why would you want to use an unstyled component? 9:58 - How can you compose an unstyled component with a styled component? 16:41 - How to decide which pattern is best suited for the code you want to share 19:36 - Using patterns that preserve React's locality of behavior 24:49 - How do you know if an abstraction is good? 32:54 - Build UI's upcoming course on Advanced React Component Patterns Links: Build UI's newest course: Advanced React Component Patterns Sam's YouTube video on Recursive Components Email Sam Email Ryan…
Sam and Ryan talk about what sorts of capabilities a tool should have to be considered a web framework.

Sam and Ryan discuss the new features in React 19 that will specifically benefit developers building single-page applications. They talk about how Suspense and Transitions let developers "teach" React about when their apps are in a loading or a pending state, how Client Actions improve upon using events in React 18 to handle data mutations, and how Actions enable React Components to automatically render and discard optimistic updates without any knowledge of the application's data layer.

Sam and Ryan talk about the difference between the costs of building a feature and the benefits that feature brings to our end users. They discuss how libraries and frameworks can lower the technical cost of building a given feature, how Ryan Florence framed this calculation in his talk at Big Sky Dev Con, and how sometimes developers’ opinions and tastes about tech can smuggle their way from the cost side of the equation into the benefit side. Topics include: 0:00 - Intro 6:53 - How Ryan Florence framed the problem in his talk “Mind the Gap” 14:38 - How frontend frameworks and backend frameworks both have their own ways of crossing the network gap 19:11 - How Network-Sensitive Interactions force technologies to grapple with both server and client environments 23:02 - How React is trying to lower the cost of moving interactions between the server and client with Server Components and Server Actions 26:53 - Why “Use the right tool for the job” doesn’t capture the dynamic requirements of living software 31:53 - How discussions about the product benefits of a feature and the technical costs of that feature are often conflated with each other 34:08 - A thought experiment from economics that highlights how uncertainty plays a role in the estimation of product benefits 56:54 - How to think about tech choice independently of the estimation of product benefits Links: "Mind the Gap" by Ryan Florence Zero-JavaScript View Transitions in Astro…
