I did not expect @discord.com to be my new favorite development environment in 2026. #hermes-agent and #discord are a great pairing.

Very exciting to see this release. It is beautifully boring and I love that.
React Router v8 is now available! - All v7 future flags are now the default (Middleware, Vite env API, Split Route Modules, etc.) - ESM-only - New baselines: node 22+, React 19+, Vite 7+ - Easy upgrade from v7
Awesome talk from an awesome conference. Highly suggest the watch.
Talks from CascadiaJS 2026 are going up, and we're going to kick things off with the epic closing keynote from @t3.gg where he dropped lakebed.dev and talked about how it's time for developers to rethink... everything! youtu.be/TV6f2weVgCI
I use both of these so I think this is a good thing.
Today, VoidZero joins Cloudflare. Vite remains MIT, vendor-neutral, and stewarded by the same wider team. The same goes for Vitest, Rolldown, and Oxc. Cloudflare is also committing $1M to an OSS fund to support independent development in the Vite ecosystem.
Excited for this one. Reading the changelog it looks like we won’t have to enable any flags for the latest features and we need to make sure we are not using react-router-dom still, which we already shouldn’t be using and totally cleaned those all up… right?
React Router v8 is now in prerelease mode! Please give it a try and let us know if you running into any issues. Learn more by reading the changelog: github.com/remix-run/re...
Finally wrote up a post on my Arashi CLI. Check it out www.corwinmarsh.com/blog/arashi and check out arashi.haphazard.dev for more on arashi and the related tooling.

Today, TanStack packages have been compromised. Again, this all started with a "pull_request_target" GitHub action trigger. TL;DR for open-source maintainers: 🚫 NEVER use "pull_request_target" workflows 🚫 NEVER use shared caches in your publish pipeline
🚨 Active supply chain attack on TanStack. 84 npm packages compromised, including react-router (12M+ weekly downloads). The malware is a self-propagating worm: steals GitHub Actions OIDC tokens, republishes itself to npm as the compromised maintainer. Socket flagged every version within 6 minutes.
Your friendly, weekly PSA that you don't have to change the world, you just have to survive it. You change it just by participating in it. When times are rough, remember that that's enough
Thinking about attending CascadiaJS solo? Do it! We created Cascadia Connect as a low-pressure way to meet other cool humans at the conference. A few things we have planned are: 🦩 Birds of a feather tables 💬 "Ask me about" conversation starters 🎲 Low-key games ☕️ Pair Programming IRL
I could go for a lot more of these two together. I first saw Star Wars at home on VHS in the 90s. I still have those VHS tapes.
on set. what about YOU?
Really enjoyed this talk by ThePrimeagen. A few real gems but I think the term toxic productivity really stuck out to me. I’m curious, do you get anxiety when your agents are idle and end up working more not less? youtu.be/V-ZvAw_VNk4?...

pnpm v11.0.0 is released! The "latest" dist-tag still points to v10, so install it via "pnpm self-update latest-11" github.com/orgs/pnpm/di...
pnpm 11 · pnpm · Discussion #11377
Migration guide: Migrating from v10 to v11 Highlights Major Node.js 22+ required — support for Node 18, 19, 20, and 21 is dropped, pnpm itself is now pure ESM, and the standalone exe requires glibc...

I think I needed this. Gonna try it out later 😄
pnpm v11.0.0-rc.5 is out! You can install it with "pnpm self-update next-11" Now you can use "pnpm pack-app" to build a single executable app with Node.js! This command is used to publish pnpm CLI itself. Docs: pnpm.io/11.x/cli/pac...
This was not on my bingo card but I’m not mad about it.
The "pnpm docs" and "pnpm home" commands will open @npmx.dev in pnpm v11.
Still all very relevant. I’ve watched this one a couple times including live at CascadiaJS. 😄
The most-watched CascadiaJS talk ever? 👀 Check out @jherr.dev’s deep dive into TanStack from last year. youtu.be/uy2WSS1MjGM
I’m going to go for a reverse April fools day and instead of making jokes, I’m going to be sad and depressed and generally not funny instead.
