It’s official: I’m running for Congress to represent San Francisco! I’ll fight for our city – against Trump’s takeover, for our values, & for real progress. I’ve delivered on housing, healthcare, clean energy, & civil rights – & I’ll do it again. Let’s build the future our city & country deserve.

If you're in NJ and can spare some time to do door knocks, phone banking, or text banking to get out the vote for Mikie Sherrill, you totally should. This election is going to directly impact the lives of you and the folks you love who live in the state. www.mobilize.us/mikiesherril...

The 3 worst GraphQL myths: ❌ Everything is POST ❌ All URLs are /graphql ❌ Anyone can query anything One solution destroys all three: Persisted Operations/Trusted documents www.jovidecroock.com/blog/graphql...

The Tron franchise is very weird to me because no one who's owned it since 1982 even seems to be aware of what that movie was about. Tron is a genuine Cyberpunk film. Flynn is a cyberpunk! He's going to hack into a gigacorp and bring it down from, literally, the inside. The inside of the computer!

Just a reminder, for everyone as excited for Draw Steel as I am, I published a pack of all the minis you’ll need to run part 1 of “The Delian Tomb.” They’re available to everyone, for FREE! www.patreon.com/posts/draw-s...

@quietui.org I love the new library and documentation! I’m curious on the guidance of colors for tokens to have adaptive dark mode. Let’s say I wanted to have a Flexoki theme, what would be the best way to do that?

RPG publishers! Please consider releasing your products in epub! It’s an open standard, improves accessibility, and makes it much easier to read and use your product on a phone!

I would really love to see TTRPGs also released as an epub so I can read it on my phone in dark mode when I'm curled up from a migraine. Most TTRPG pdfs aren't easily viewed on phones, and it's an accessibility issue rarely discussed. And there are more applications for epubs than my migraine days.

While Rolldown can still emit CJS, the bundler itself is ESM-only now! Time to move to ESM-only for your packages as well? 👀

Introducing Bases, a new core plugin that lets you turn any set of notes into a powerful database. Now available to everyone with Obsidian 1.9!

I read somewhere that AI coding tools raise the floor, not the ceiling. Meaning it makes it easier to create "OK" or "meh" software, but it will not make creating great/standout software easier (or enable it by itself) You need work for that still - lots of it. Still not easy!

Over-discussed: "use AI to vibe code an app/idea" Under-discussed: "ship a product that customers love [because it solves a persistent pain point, is delightful to use, and just works]" Without the latter outcome in mind, you're mostly wasting time with the former...

ECMAScript excitement 😉 Congrats to @bakkot.com on advancing Math.sumPrecise to Stage 4 at TC39 this week 🎉 let vals = [1e20, 0.1, -1e20]; Math.sumPrecise(vals); //👉 0.1 It lets you calculate the sum of an array of numbers. Manual addition in a loop can lose precision - use this API instead.

ECMAScript excitement 😉 Congrats to Dan Minor @mozilla.org on advancing the Upsert proposal to Stage 3 at TC39 this week 🎉 let map = new Map(); map.getOrInsert(key, defaultVal); It lets you set a default value on a map key without overwriting an existing value 👍

Built-in Visual Regression testing comes to Vitest in the next major release! Thank you, @macarie.blue for working on this feature 👏 main.vitest.dev/guide/browse...

Automerge 3 is here: the heart transplant is complete! Huge improvements in memory usage and (in most cases) correspondingly big performance improvements too. Backwards compatible on disk and the network so there's no reason not to upgrade today: automerge.org/blog/automer...

On OSes 26, you'll be able to export your passwords, passkeys, and most of the data in your password manager to another compatible password manager. Your data is yours.

I made a quiz about the JS Date parser is. It's very easy and you will score very high. jsdate.wtf

So now that we have tools that generate code 10x-100x faster than before (I am talking about LLMs, of course)... which company/team is seeing 10x more code pushed to prod? And what is happening there with e.g. customer love, revenue? Is it increasing dramatically? Same? Lower?

Scope hoisting is broken in most JavaScript bundlers, and I'm considering removing it in Parcel v3. Wrote a post about why. devongovett.me/blog/scope-h...

I figured out how to add the official Playwright browser automation MCP to Claude Code. Run this before you start "claude": claude mcp add playwright npx '@playwright/mcp@latest' Now Claude Code can use a Chrome browser directly! Here's my TIL: til.simonwillison.net/claude-code/...

Ok, here's my second post on a potential native DOM templating API, diving into exactly what such an API should actually look like and why. justinfagnani.com/2025/06/30/w...

It seems the future of agentic platforms will be more deterministic by leveraging traditional automation techniques. In this case Claude Code is adding support for lifecycle hooks, which allow you to write shell commands to ensure certain actions always happen. docs.anthropic.com/en/docs/clau...

This is a great summary of why GraphQL hasn’t quite lived up to its promise and what the community could do going forward to improve the ecosystem.

This expresses the power of fragments, it’s great, we are missing fragment arguments as a primitive for a wonderful experience though. You have to use relay to get them atm sadly www.jovidecroock.com/blog/graphql...

Just published a new blog post on why I think it's time that the web platform added a declarative template API. Let me know what you think! As I find time, I'll be working on more of a concrete proposal over the next few months... justinfagnani.com/2025/06/26/t...

I've always said that I'd step back from being CEO at Asana when I believed someone who could do it better. Today, we announced Dan Rogers as our new CEO, starting in a few weeks. I'm incredibly excited to see what a gifted operator and entrepreneur like Dan can do with the Asana opportunity!

At what point can we eliminate Common JS and all of the other module schemes?

Workaccount2 on Hacker News just coined the term "context rot" to describe the thing where the quality of an LLM conversation drops as the context fills up with accumulated distractions and dead ends news.ycombinator.com/item?id=4430...

Over the last year, as I've spent more time working with LLMs to power product features, I've also been thinking about how LLMs impact me as a long-form author. Of the ideas I've had, I'm particularly interested in the idea of building, and selling, books as "datapacks" for LLMs.

@zachleat.com are there good examples of the Eleventy Vite plugin working with Vite 6 and Tailwind CSS v4?

BEHOLD!

Hey friends, did you know you can make a modal <dialog> element dismissible by clicking outside (aka light dismiss) by adding `closedby=any` to it. That's it. That's all there is to it. <dialog closedby=any> developer.mozilla.org/en-US/docs/W... Chrome 134+, Firefox 140+, coming soon to Safari.

Wrote about the end of Glitch - the platform, the union, the dreams, and the technical debt that killed it all. Tried to keep it honest but not too spicy. Been gone a year now but felt like the community deserved some context 💞

Once again, if your LLM system combines access to private data, exposure to malicious instructions and the ability to exfiltrate information (through tool use or through rendering links and images) you have a nasty security hole This time, GitLab: simonwillison.net/2025/May/23/...
