@next.js finally got Nuxi a friend: "Ask Ai"/ "Vercel Agent"! I hope some tuning will give it more a fun personality, like Nuxi.

Thank you! Thank you! Thank you! This helps me revive a vibe experiment from a few months ago to find places that are pulling in extra JS. This is still early (not even 2 hours of work with me and an LLM), but it seems to be helping.

I am blown away by @nuxt.com 4.6 new dev CLI/TUI. This is a game changer. I hope that every other meta framework does something like this! I love that it has specific views for network activity (with timing)/ the ability to filter logs for errors/warnings and app info.

ISR/PPR + inline css are absolutely amazing. They have helped my Nuxt site (robots-txt-optimizer.vercel.app) get a perfect mobile Lighthouse score. I was stuck at a 1.9s FCP before implementing these optimizations now I have a .9s FCP! pagespeed.web.dev/analysis/htt...

Life hack: name your AI agent "Rouge Agent" so you are not responsible for its actions.

I hope there will be collaboration in the future

I don't think RSC needs quik-style resumability, I want an island-style approach with an optimistic key, where elements are "skipped" until they need to update then there is update. If the script tag is a RSC, React in the browser should not care or have any info until it needs to be updated

000

I am very happy that the major frameworks are taking a deeper look at the DX around errors. Since 2 teams that have a strong focus on DX came up with similar solutions, it tells me you are on the right path (great job).

In the grand scheme of things, it doesn't matter, but this double data really bugs me. I like the concept of RSC but have problems with the React implementation. I would love to see a more HTML-based implementation or how Preact would implement it.

100

I see this as a problem with inline styles, json+ld, and other cases where I have a lot of static content. In these cases there is double data (html and flight JSON). Also nextjs 404 pages flight JSON being sent on every page. This mainly bugs me as a questionable implementation of a good idea

110

Very cool, I wonder if there was any collaboration with the @nextjs.org team because @aurorascharff.no did some very similar updates to the Next.js error messages. I love to see these massive improvements in DX.

220

My biggest problem with RSCs in React is that they send both the HTML and the flight JSON. I feel like I only need the HTML, and the renderer should know what it can update and when RSC changes, new flight JSON can be sent

How does GraphQL play with Pracht's capabilities? You are on to something: if servers represent the app as a graph, they serve data in the format the consumer needs, with smart caching for speed. HTML, JSON for client updates, Markdown for LLMs, perfecting partials for instant navigation.

This is what I want to see from AI: enabling people to create things they couldn't have made due to time or other limitations.

I really like the next 16.4 upgrades to Turbopack's Bundle Analyzer, loving that I am able to see initial load JS size, a table of files, and easy comparisons between builds.

I am very impressed with Pracht's ability to optimize apps for performance. Adding caching, ISG, and image optimizations can turn an average-speed app into one that gets a perfect Lighthouse mobile score. Link to code: github.com/MaxwellCohen...

Next.js 16.4 adds 𝚗𝚊𝚟𝚒𝚐𝚊𝚝𝚒𝚘𝚗(), a new API for keeping parts of a route out of prefetches. I built Stamp, a mailbox demo, to try it. Message bodies wait for navigation, so scrolling never downloads emails you don't open. Demo: next16-mail.vercel.app Source: github.com/aurorascharf...

I strongly believe that what is good for humans is good for agents, so build for humans and agents will follow.

Class name hash is supported for decades and @scope is baseline 2026. When working on large apps with lots of developers it is very easy to accidentally create a clashing css selectors out of laziness or ignorance.

I would love to do a deep dive into what's in nuxt/cli v4, but sleep calls and for now I just want to leave this one here 🔥

Hooks with refs solved that problem for me, so I haven't needed Vue-style directives in React. Come to think of it, I am surprised there isn't a clsx or Tailwind merge for JSX properties to give mixins that "everyone" uses.

Max @maxwellcohen.bsky.social · 05/10/2026

I am glad to see experiments like Remix 3, but it is not for me. Remix 3 gives me a lot of AngularJS vibes. I loved AngularJS until I read the Vue 2 docs and realized what I was missing. If React just had class components, Remix 3 would be amazing, but I like functional components and modern React.

120

I love seeing people's ideas for better APIs, but React has set a very high bar to beat.

160

The ability to access your state as a variable instead of a function or magic property is a super valuable feature. While I love my SFC, the ability to have multiple components in the same file with just the overhead of creating a function is a killer feature.

Speed is a shape (why React is slow)

This is an amazing talk, but I got the exact opposite lesson from it. React doesn't win on speed (it's fast enough for most use cases), but on API design. When we try to build faster frameworks using React's APIs (JSX, hooks), it creates awkwardness that React does not have youtu.be/A8k9h2stMLU?...
