deployed big update to rsc-playground.pages.dev lots of bugfixes and a few new examples. this basically works now! i'll open source a bit later

Tis the season for me to remind you that the Spike Jones Xmas Spectacular is the best Christmas album: jordaneldredge.com/spike-jones-...

I updated grats.capt.dev internal snapshot tests to serialize using markdown and the result is so nice! Snapshot output now has syntax highlighting and nice readable headings showing what each bit of the output means.

x.com/panchito built a _really_ slick looking Github file viewer clone that fully uses RSCs and new React features, as well as making smart use of modern CSS. Great writeup on the implementation: wtbb.vercel.app I tried browsing the React repo example and it's _fast_! Really impressive!

maybe not the best moment for it but i finally condensed my “why react server components” into a short blurb that does well on HN

Ever wonder how GraphQL clients like Relay keep your app’s data perfectly in sync without extra network calls? 🤯 Meta’s Sabrina Wasserman breaks down the core engine behind modern GraphQL clients. Watch here 👇 www.youtube.com/watch?v=hz0...

I think the npm client should probably follow pnpm in making post-install scripts be opt-in and recording that decision in package-lock, so if a package that was previously inert suddenly has a post-install script, it wouldn't execute. www.sonatype.com/blog/the-sec...

I simply refuse to accept that police ever have to look like this. this is just pure cosplay. it should be illegal for cops to be dressed like soldiers going to war.

This weekends exploration for the Winamp Skin Museum: what if you could algorithmically doom scroll Winamp skins 🤔

@communityinter.net nice to meet you at the park today!

This is very clearly the direction in which things are headed, especially since so many of the people who built and maintained the tools the US IC has developed-in house have been fired or have left.

One of the huge perks of working at a software company is, when there's something about the product that bothers you personally, you can get your hands dirty and find out why it's basically impossible to get fixed

GraphQL error handling sucks. There, I said it. Null checks everywhere, and ambiguity: error, or true null? We've all been there. In this talk, Benjie Gillam shows how to fix GraphQL's biggest mistake in 512 bytes. 👇 youtu.be/odwQUAkmW44

There were only about 50 skins which were not already in our collection. Further confirmation that the museum's >101,000 skins represent the vast majority of all skins ever created.

I’ve been made aware of a 2013 “panic download” archive of downloads.nullsoft.com containing ~60k Winamp skins. Downloaded and hashing all the files to find any which are not already in the Winamp Skin Museum.

Exciting progress today! Called with @capt.dev about the React "concurrent stores" prototype, and we brainstormed potential Redux integration issues. I then whipped up a prototype branch that reworks `useSelector` to use the prototype, and _most_ tests pass! github.com/reduxjs/reac...

LuigiHann designed this around 2018 to celebrate the @archive.org integrating Webamp and adding a dedicated collection of Winamp skins.

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms). It’s also concerning. 1/

somehow @capt.dev revived this Winamp 5 skin I made 21 years ago

OpenAI's CISO Dane Stuckey posted an essay (on Twitter) about how their new ChatGPT Atlas browser attempts to deal with the risk of prompt injection attacks, I ended up writing a point-by-point commentary on my blog: simonwillison.net/2025/Oct/22/...

Works especially well with SQLite’s full text search. Been building a little search DSL for my site which compiles to SQLite’s FTS+structured search/sort conditions. github.com/captbaritone...

Markdown+metadata is such a good format for blog posts. But deploy-to-publish feels heavyweight, and I often want to publish from my phone. Current setup: Author in Notion and pull from Notion API to Markdown in SQLite DB. Site renders from SQLite.

Minting admin API keys with an unauth POST request is a wild bug to have zeropath.com/blog/breakin...

Winamp skins are (literally) zip files. And sometimes there’s weird stuff inside them. jordaneldredge.com/notes/corrup...

Been using this repo to iterate on API ideas for a concurrent compatible store for React. Still exploratory but excited that we’re very close to something that we can start trying out with existing data stores and start an iteration cycle based on what we learn.

Shipped Grats v0.0.34 🚀

Got into a conversation with a friend last night about implementing permissions in GraphQL/Grats. Inspired me to write a guide for the Grats docs outlining three strategies that work well. One that I think is particularly elegant is Permission Tokens leveraging Grats' Derived Contexts.

I built Grats' Derived Contexts on a whim, but it ended up being a simple yet powerful compile-time dependency injection engine. A field just defines its dependencies via typed arguments and Grats ensures it gets passed a value at runtime.

Introducing the React Foundation

As an example: My personal blog (Next.js/RSC) also exposes a GraphQL server: jordaneldredge.com/api/graphql/ I just sprinkled some (68 according to grep) `@gql*` docblock tags around and got it for free by running `npx grats`.

Joshua Rogers, using AI tooling responsibly and professionally, reported 22+ genuine issues in curl that are now being addressed Especially notable because curl had problems with floods of garbage slop AI "security issues" in the past that were nothing of the sort simonwillison.net/2025/Oct/2/c...

I designed Grats' around "error driven development": each error provides specific guidance on how to fix it. This has proved a good fit for AI agents. I asked Claude to find an interesting SQLite DB on my computer and build an API using Grats and it did without any help!

An interesting aspect of AI for software library maintainers, is that it's now possible to have a fast feedback cycle on API design and documentation. 1. Design/document and API 2. Have AI try to use that API with docs 3. See how it fails 4. Improve API/docs 5. GOTO 2

The @archive.org got in touch about adding Milkdrop (Butterchurn) to their Webamp integration. This lead me to: 1. Build a new entrypoint includes Milkdrop by default 2. Writing a detailed, long-overdue docs site docs.webamp.org Very cool to see Milkdrop visualizer presets alive and accessible!

Blog post: A Mental Model for Data in UI Applications jordaneldredge.com/notes/ui-data/

Prototyping a version of the Grats playground where you can actually execute your schema right in your browser (in a worker).

React server components are great if your backend is Node and your rendering for the web. But what about native clients? Grats is great for this: Define your data using models for RSC, then simply annotate those same models so that your native clients can consume the same data via GraphQL.

🌟 Shoutout to @capt.dev, Relay maintainer and nullability champion! From shaping the “true nullability schema” to sharing critical insights, your impact on GraphQL is huge 🙌 #GraphQLStar

Got a perf benchmark and profiling working for Grats. Next release should be about 25% faster for large schemas!
