Everyone you meet is fighting a battle you know nothing about. Be kind. Always.

fastest url parser for python is now 32% faster. nice!

Thank you for your sacrifice

I just published a new blog post: "State of URL parsing performance in 2025". I hope this answers all of @bagder.mastodon.social.ap.brid.gy's concerns. www.yagiz.co/state-of-url...

🚀 BIG NEWS: We just shipped @platformatic/python - run Python ASGI apps INSIDE your Node.js process! This changes everything for AI/ML + Node.js apps 🧵 youtu.be/8eAAP9IF4xA

I'm nervous to speak but I'll be there ready to stand with my fellow union members ✊

Bringing Node.js HTTP Servers to Cloudflare Workers, by @yagiznizipli.com and @[email protected] (@[email protected]): https://blog.cloudflare.com/bringing-node-js-http-servers-to-cloudflare-workers/ #cloudflare #nodejs

I know I was a bit mid on my opinion of landing `--run` original (sorry @yagiznizipli.com), but now that I have been using it for a while, I absolutely think it was a great addition.

adding oauth2.0 to my hello world app.

To be clear, .env/ini are both kv formats & likely* could use the same internals. What's unergonomic about defining kv options as kvs in config? With JSON I'm forced to write a bunch of extra syntax & still nest NODE_OPTIONS(?) IMO feels like we're putting config in an extra place for no reason

Did you know there are now 5 full time @cloudflare.social employees actively contributing to Node.js? (Plus a summer intern).

After investing thousands of dollars for my home infrastructure and connecting to call of duty servers with 7ms ping, I am proud to say that I still suck.

We should tell @yagiznizipli.com what a kitchen really is 👀🤣 Joking. Great to see Yagiz on the stage, good luck! 🫡

Node.js is like a kitchen: you can optimize it for the fast path to make it run more smoothly. @yagiznizipli.com a Node.js core contributor, serves up wisdom and performance optimizations in this SquiggleConf 2024 talk. 👨‍🍳 youtu.be/5j_67zw63Hw

Say hello to my very old friend @expressjs.bsky.social running on @cloudflare.social workers!

come work with me!

Some things that will (fairly soon) Just Work in Cloudflare Workers: import { readFileSync } from 'node:fs'; readFileSync('/bundle/config'); const r = await navigator.storage.getDirectory(); const tmp = await r.getDirectoryHandle('tmp'); const file = await tmp.getFileHandle('foo',{create:true});

copilot (claude sonnet 4) spent 15 mins writing failing unit tests and modifying irrelevant existing code. i threw it all to trash, writing the tests from scratch myself now. junior devs may not know everything, but they at least know what they don't know. and that makes a whole lot of difference.

PSA: The node:http get and request methods will soon be available for use on Cloudflare Workers with nodejs_compat mode github.com/cloudflare/w...

What's that you say? Cloudflare Workers might be soon gaining the ability to run express and fastify apps directly? That would be crazy!! Stay tuned ;-) github.com/cloudflare/w...

Apparently there was a joke event in Peru where all the jockeys raced each other instead of their horses

barber took too much off the top

It was a day full of emotional roller-coaster.

We're thrilled to announce the first stable release of Oxlint - version 1.0! Our Rust-powered JavaScript/TypeScript linter delivers 50~100x faster performance than ESLint with 500+ rules and zero configuration required. Time to give it a try! voidzero.dev/posts/announ...

Obituaries read like LinkedIn profiles, and it's hard to watch it being written right now. I know everyone means well, and they're showing their respect and love of what they saw of him. Just my grief making me grumpy about it. I want to scream, you all don't even know how much was lost!

Our hero!

Coming soon in @Cloudflare Workers, we will be enabling use of eval only at the top level scope. This means that you'll soon be able to use eval and new Function(str) during the start up of your worker. It'll still be disabled within requests. Hat tip to @yagiznizipli.com who landed the PR today.

It's been almost a year (will be in 1.5 months) since I started working at @cloudflare.social I'm still amazed by the level of pull request reviews and the many opportunities to learn. The last time I felt exactly like this was when I started contributing to Node.js.

... * perf improvements done by @yagiznizipli.com * require(esm) added by @joyeecheung.bsky.social * type stripping added by @satanacchio.bsky.social * test runner/sqlite added by @cjihrig.bsky.social regular KTLO work done by @targos.dev, @aduh95 and more! (2/2)

May the 4th be with you too @isaacs.bsky.social

There was a special moment in Berlin 2019 when I was reviewing the spec. A magical 60 seconds when I had just enough context to hold it all my head to understand it... and then it was over. Good luck!

Happy EOL day @nodejs.org 18

I hate templates now. github.com/cloudflare/w...

@yagiznizipli.com and I have started working on an implementation of node:fs for @cloudflare.social workers... Which is fun because there is no file system to speak of. It'll be fully virtual and in-memory. My question for y'all is: what features would you consider to be critical?

I wasted 4 hours of my life due to amd-driver getting executed for nvidia graphics card. WHY??

👀👀👀

Would someone be interested in funding/sponsoring the work of adding V8 Fast API to almost all supported Node.js functions? Each addition improves the function performance by 40-60%.

I wish Claude had a higher context window. 200K isn’t enough.

I have so many cool friends

Iterating through keys and values in C++ (with C++20 code) https://lemire.me/blog/2025/04/20/iterating-through-keys-and-values-in-c-with-c20-code/ In software, we often use key-value data structures, where each key is unique and maps to

Guess how much I pay to Cloudflare for this?

Amazing news! People underestimate URL parsing until they read our paper.

Our paper (with @yagiznizipli.com) 'Parsing millions of URLs per second' is a highly read paper according to the editor (Wiley). onlinelibrary.wiley.com/doi/10.1002/...

Today, I brushed up my C++ by implementing monitoring of the memory consumption of a @nodejs.org thread from the parent. Thanks to @yagiznizipli.com, @legendecas.bsky.social, @joyeecheung.bsky.social... I've learned quite a few things! github.com/nodejs/node/...

we have a winner!

Since everyone is sharing updates... A month ago my former manager messaged me and asked to transfer publishing rights for an old library I worked on while I was at CF. I was so confused, I did the only logical thing possible and... I'm re-joining @cloudflare.social as a Sr Principal Engineer!
