About a year ago, Vercel released Next 13.4, becoming the first React framework to be built on top of React Server Components (RSC). ✨

This is really exciting, but also, a bit concerning for folks who use CSS-in-JS libraries like styled-components.

Let’s talk about it. 🧵

Too many dev blogs do not have RSS feeds 😭

What prevents you from adding one?

I would usually fallback to using Inoreader artificially created 'Web feeds', but unfortunately this does not work for sites hosted on Vercel 😅

Is there a way to bypass this Guillermo Rauch ?

After 8 months of planning, 12 hours of filming, and 2 weeks of editing, my biggest project has been released.

The Modern Full-Stack React Tutorial is now live, FOR FREE, on my YouTube channel

📚 It's been almost 1.5 years since I wrote my first blog post about working with zustand. It's about time I wrote a follow-up piece - about using zustand together with React Context

📜 Are Inline Styles Faster than CSS?

Daniel Nagy implemented his React website in 3 variants
Then measured different metrics: HTML/JS size, Vitals, etc...

Result?
Plain inline styles outperform other CSS techniques! 😲

ECMAScript excitement 😉

This week TC39 advanced these proposals 🎉

4️⃣ RegExp: Duplicate Named Cap Groups
4️⃣ Set Methods
3️⃣ eval for Trusted Types
3️⃣ eval-injected global var is redeclarable
2️⃣.7️⃣ Math.sumPrecise
2️⃣.7️⃣ Promise.try
1️⃣ Error.isError
1️⃣ Signals
1️⃣ Strict `using`

Does it make sense to use Signals in Nodejs?

Like, for DX / dev server / hot reload stuff?

🥲 Good hydration error DX

Next.js 14.2

◆ Turbopack (RC): 99.8% of tests passing for `next dev --turbo`
◆ Build / Production Improvements: Reduced memory usage
◆ Caching Improvements: Configurable client-side cache revalidation
◆ Errors DX: Better hydration mismatch messages

Woah! This just went live in Next.js 😄

Looks great:

👀 React 19 + Form resets

Uncontrolled forms will reset on action end
(no impact on controlled form inputs)

New public API to trigger behavior manually in transitions: ReactDOM.requestFormReset

New React Root docs are now published

Better error messages are coming to React! 🎉

React is getting new ways to handle caught/uncaught errors, and this new capability is already being used to improve the reporting on hydration mismatches.

i'm playing around with React Native new architecture examples using [email protected] and [email protected], and it's pretty cool to see automatic batching with native event handlers in action.

🔥 React 19 will be much faster at creating JSX elements

(when using the new JSX runtime)

Recent changes in how key/refs are handled make it possible to avoid cloning props

Since we create many JSX nodes, this should have a significant impact
