speaker_1HOST
And honestly, this is a massive architectural improvement.
speaker_1HOST
How so? Well, instead of cramming every single instruction into that one claw.md file at the root, which bloats every single prompt, you can have a specific markdown file in the rules folder just for, say, front-end React conventions.
speaker_0HOST
Oh, and the genius of that is that it only loads when Claude is actually looking at front end files, right? If it's debugging a Python backend script, it ignores the React rules completely.
speaker_1HOST
Exactly.
speaker_1HOST
It uses path matching to dynamically inject context only when it's highly relevant.
CJ ReynoldsPANELIST
it.
CJ ReynoldsPANELIST
Don't click away because we're talking about React.
CJ ReynoldsPANELIST
So React 19.3 was released.
CJ ReynoldsPANELIST
It's now available to install from NPM.
CJ ReynoldsPANELIST
And there's a couple of quality of life improvements.
Adam BienHOST
Okay.
Adam BienHOST
And this is, it looks like React, but it isn't.
Adam BienHOST
And I use it as a starting point for lots of enterprise projects.
Adam BienHOST
So I could actually use the web bundler.
Jack HerringtonHOST
React is back with its latest version, 19.3. There's a new type of model
TJ VanTollHOST
in town,
Jack HerringtonHOST
and Shopify is ditching React Native.
Jack HerringtonHOST
Let's get into it.
Jack HerringtonHOST
Hey, welcome back.
Jack HerringtonHOST
Let's get on with some news.
TJ VanTollHOST
Let's do it.
Jack HerringtonHOST
All right, Paige, what's going on with React?
speaker_1HOST
Let's look at a classic debugging nightmare.
speaker_1HOST
You are building a complex React front-end application.
speaker_1HOST
You are deep in the trenches with the cloud code agent, trying to figure out why a specific user interface component refuses to render data.
speaker_0HOST
Been there.
speaker_1HOST
A tiny CRS error cross-origin resource sharing.
speaker_1HOST
You suddenly get a wild nagging theory.
speaker_1HOST
What if the React component is perfectly fine and the real issue is that our Python backend server is rejecting the request because of a misconfigured security header?
speaker_0HOST
Okay, I have my wild theory, but investigating a Python backend security configuration is a massive context switch.
Dan NeciuHOST
I'm guessing inside Netflix, you have all sorts of technologies.
Dan NeciuHOST
I don't know if you have different front-end frameworks or it's only React.
Dan NeciuHOST
But how do you make a design system work with all of these technologies because your consumers are thousands of teams that you said product teams.
Szymon ChudyGUEST
Yeah, that's correct.
Szymon ChudyGUEST
And I think this is a moment we can do a nudge to Lenny's podcast because recently Elisabeth Stone had been featured there and she shared like a great observation about So
Dan NeciuHOST
how do you build the design system so other people can consume it in different technologies? Maybe someone in React, someone in Vue, someone
Szymon ChudyGUEST
in, I don't know, raw HTML.
Szymon ChudyGUEST
Yeah, that's perfectly valid question.
Matt LawrenceHOST
Like you're starting to code closer to the metal.
Matt LawrenceHOST
There's going to be, there's going to be examples, for example, within the web development space where React and these other frameworks and libraries and tools that we've made Svelte, the rest of them, These tools are made as more or less human interfaces a lot of the time to help people create maintainable, readable code across a team.
Matt LawrenceHOST
But at the end of the day, the browser really only understands the three pillars that we've talked about repeatedly in the past.
Matt LawrenceHOST
And so a code, an AI that is doing some coding for you could...
Richard FeldmanHOST
So, you know, this is a debate I got into with someone I actually respect a lot as a designer recently.
Richard FeldmanHOST
I was making the opinion that, like, so there's, like, React and there's Next.js on top of that.
Richard FeldmanHOST
You don't even want to know what that is, but it's a thing.
Richard FeldmanHOST
It's popular.
Richard FeldmanHOST
A website you should check out is, I think it's vanillajs.com. And it basically is like a marketing website for like, oh, it's vanilla.
Richard FeldmanHOST
And they're like, look, compare the bundle sizes.
Richard FeldmanHOST
Look, compare it to React and this.
Richard FeldmanHOST
And you can like check all these options.
speaker_0HOST
Technology moves so fast.
speaker_0HOST
If you grab a React course on Udemy, you better make sure it is teaching functional components and hooks.
speaker_1HOST
Not the outdated class-based architecture from five years ago.
speaker_0HOST
Precisely.
speaker_0HOST
It is the red error messages that actually force the learning.
speaker_1HOST
Exactly.
speaker_1HOST
It focuses relentlessly on raw fundamentals like vanilla JavaScript before it ever lets you touch a framework like React or Vue.
speaker_0HOST
To build that muscle memory.
Geoffrey LittGUEST
But often I think what you want more is what are some higher level primitives that we can be recomposing.
Geoffrey LittGUEST
And some of those might be just like React libraries or things like that.
Geoffrey LittGUEST
Obviously libraries are kind of, I think are more valuable than they ever have been because coding agents can glue them together.
Geoffrey LittGUEST
That's one form, but there's other forms we can imagine for how we glue software together.
