🎉 Author copies are in! 📚 Holding the 4th edition of “Node.js Design Patterns” never gets old. Months of work turned into something I can touch, and hopefully a guide to help you level up with Node.js.

Another banger from Marvin on performance wins in the JS ecosystem 🔥 The theme across the series is that orders-of-magnitude wins are often sitting in plain sight purely from eliminating duplicate work & improving algorithms. These are language-agnostic principles.

I predict the AI bubble will pop in way similar to how Google products did in the 2010s. They were "too good to be for free", and eventually advertisements kicked in. Product quality stagnated (just marginal improvements), while monetization ramped up a lot, e.g. ads on YouTube.

I've returned to writing after more than two years.

AST based V8 code coverage is finally here! I thought of this feature first time over 2 years ago, but knew it would require so much work that I couldn't finish it by working on Vitest just on weekends. Ever since @stackblitz.com hired me to work on Vitest I knew I could finish features like this.

I reviewed this edition, and what was already a must-read book is now a mandatory read. I highly recommend it to seasoned developers as well.

📘 The new edition of Node.js Design Patterns is coming soon! After 9 months of hard work with Mario Casciaro, we're finally ready to share what’s next for one of the most loved Node.js books. But this is not “just another edition”...

Folks, right now @rafaelgss.dev is doing an awesome livestram on m.twitch.tv/rafaelgss talking about Node.js threads, memory management and perfs. Join us!

I updated fastify and its dependencies to 5.x.x in our private monorepo. Buttery smooth. If you need to do the same, follow fastify.io/docs/latest/..., and you’ll be covered!

Node.js has had support for running TypeScript directly since v22.6.0. I’ve been wondering what a minimal Node.js with TypeScript starter project might look like. Here’s my first shot at what I think might work for me. And it's my first blog post in over 2 years! simonplend.com/blog/a-node-...

Now that I have finished the base implementation for Valkeyrie, I will focus on the documentation. Until now, it has all been AI-generated with subpar results. Thanks to extensive tests and comments, I still want to figure out how to make it 100% AI-generated. github.com/ducktors/Val...

There are no technical hurdles at this point. We're just building the solution now, hopefully in time for Node.js 18 EOL.

The Key-Value store is coming together so well. The api is fully compatible with @deno.land KV. There is also the concept of pluggable drivers. The plan is to support as many underlying DBs as possible. node:sqlite driver ships included. Oh the name is awesome: Valkeyrie! github.com/ducktors/val...

Want a remote cache for your turbo-powered project? Are you too cheap to pay Vercel? (I am!) Do you happen to already have access to S3? Here is a tool that allows you to run your own Cache server automatically as an on-machine daemon: github.com/NullVoxPo... Be your own Vercel! <3

🕳️ node-modules.dev v0.4.0 is just out! ⚠️ Deprecated packages 🌈 Clusters by @pnpm.io catalogs 🔼 Latest version indicator 📖 publint.dev integration Thanks @jyc.dev @43081j.com @bluwy.me @sxzz.dev et al. for the PRs, brainstorming, and tools! 💚 We should really take some actions to cleanup now! 🧹

I am excited because I found a fabulous weekend OSS project I can start developing. Key/value store + Node.js. I feel that using Crusor + Sonnet will significantly speed up the development.

Unfortunately this article is inaccurate. Request and Response have been available in Node.js since v18 (and WinterTC compliant) It is possible to test node.js http server without opening socket github.com/fastify/ligh....

# @unjs.io ohash.unjs.io v2 - 🚀 Speedup with node:crypto when available - 🪴 Serializer rewritten - 🧹 Internal cleanups - 📦 ESM-only (63.3kB=>18.7kB) Bundle size down to 5.5/2.6kB (web), 2.3/1kB (node) changelog: github.com/unjs/ohash/r...

Landed a PR that integrates TypeScript transpilation into the Node.js compile cache ✨ When benchmarking files of 500-600+ bytes, type stripping is 65% faster and full transform is 128% faster (it should be more significant on bigger files though, because it's a cache) github.com/nodejs/node/...

My first AI course is complete... And it's free! It's a 16-lesson tutorial on Vercel's AI SDK. It's the missing piece for working with AI in TypeScript. No bullshit, no hype. Just solid, practical advice. https://www.aihero.dev/vercel-ai-sdk-tutorial

I just started sponsoring @adima7.bsky.social 💙 Aditya is doing great work in the @hono.dev ecosystem, and also in some new bsky projects 👀 Consider sponsoring him and other awesome maintainers doing OSS tooling for all of us: github.com/sponsors/Mat...

Vitest 3.0 is here!

Today, we're open-sourcing OramaCore. Fulltext/vector/hybrid search, built-in embeddings, built-in LLMs for inference, and RAG. That's the hardest project we've ever worked on, please leave us a star and follow @orama.com to stay updated 🙏 github.com/oramasearch/...

Big performance wins may be possible for Node's TypeScript integration thanks to @joyeecheung.bsky.social's multi-year efforts to implement Code Caching in Node 👍

I said it once, but... @vitest.dev Browser mode rocks!!!! Even more with vitest-browser-react github.com/vitest-dev/v.... I get 115 React components unit tests running in 2s **in the browser**! And 90% of the time goes just for changing the viewport, so I know what to optimize!

I would have to say... if you need to run benchmarks in Node.js, you should probably check out mitata. https://www.npmjs.com/package/mitata

We're back in open source lands, so at least the pressure can be distributed a bit on everyone that'd like to get their hands dirty. The best for what's coming bluesky team, we're rooting for you 💙

Here's a tip if you want to contribute to an OSS project. If you find a bug you want to fix, get involved with the maintainers and comment on the issue you want to fix the bug. Don't straight send a PR. If it turns out someone else did the job before you, you might have coded for nothing. #oss

I added bsky as the first social in my GH profile. At some point, I will remove that other thing altogether.

I updated my handle to maksim.dev This is so cool! 😱

Also, this one for the JavaScript go.bsky.app/6jDsWb5

The time has come to move here as the main platform for posting. I still need to set everything up, but I already see some vibes that are long gone somewhere else.
