Luciano Mammino 𝕏 Node.js Design Patterns

🎉 Big news and a gift for you 🎁 Keep reading🧵👇

Node.js 26 shipped this week 🎉 My birthday is close, so I'm officially calling it an early birthday present from the Node.js team 😂 It doesn't look flashy at first, but the additions are genuinely useful in everyday code. I wrote a code-heavy tour, here's what stood out 🧵

The article shows the new API side-by-side with the old one for every feature, plus a companion GitHub repo with every snippet ready to clone and run. I hope you'll like it 🙂 nodejsdesignpatterns.com/blog/whats-new…

Plus the cleanup: private _stream_* modules, http.Server.writeHeader(), and --experimental-transform-types are gone. module.register() is runtime-deprecated. If you maintain libraries, this is a good time to grep for those.

New post: Writing middlewares for #Rust #Lambda functions 🦀 The #AWS Lambda Rust runtime already ships a middleware engine: tower. Almost nobody is using it. Deep dive + a complete #DynamoDB rate limiter you can steal: loige.co/writing-middle…

Little update on my reflection adventures: I have extracted the core components of Pavex's compile-time reflection engine as a set of standalone crates! It serves as a preliminary step ahead of another release in the coming weeks 🛠️

PS: the post is sprinkled with rabbit holes 🐇, curious deep dives into things like async fn in traits, hand-rolled futures, fixed window vs token bucket, why `CorsLayer` works on Lambda, and more. Make sure to click into some of them. Just try not to get lost in them 😉

All the code lives at: github.com/lmammino/rust-… Clone it, `sam deploy`, and you are 5 minutes away from a working tower-based rate limiter on AWS. Let me know what you build with it 👀

@wesbos @setheliot Shenaniganing... My favorite one 😂

Claude Code leaked their source map, effectively giving you a look into the codebase. I immediately went for the one thing that mattered: spinner verbs There are 187

@MatlokaM @posthog Wow, thanks for sticking around for so long! You have probably seen all the evolution, especially in the last couple of years! Massive thanks also for all the support through @posthog, it has been fantastic to work with you guys and your content always rocks!

@loige Thank you so much for every edition 🧡 I just checked my inbox: FullStack Bulletin first landed in it exactly 5 years ago, March 2021. It's been a joy, and so many interesting tidbits. I'm happy we got to support some of it as @PostHog

For the past 9 years, I have been running a newsletter called FullStack Bulletin. Every week, I hand-picked articles, tools, and resources I could find for full stack developers. Over time, that turned into 450+ issues, 3k+ curated links, and a community of 3k of readers.

@sebastienlorber Thank you so much! It has been a wild ride... part of me will miss it forever, another one is probably relieved :P

@loige I feel you, not easy to keep publishing every single week Congratz on sticking with it for so long!
