Next @_ai_collective demo night in London with @Darktrace and @incident_io Demos from @Xbow @HelmGuard @incident_io @EmaaaPop Sign up using the link in the comments

@Xbow Our showcase traces are my favorite part. You can read actual traces of XBOW at work, and the things it can do have been really astonishing to me: CBC padding oracles, remotely debugging an exfiltration exploit on a compromised server, and more:

A few months ago, I left @Cloudflare to join a new startup. I really enjoyed working at Cloudflare, and there was lots more stuff I wanted to build, but this seemed like a very exciting opportunity I'd regret not taking. Introducing XBOW! 🎉

🌊A deep dive into how @_mrbbot & colleagues built support for running Vitest tests in the Cloudflare Workers. Brendan will start by giving an overview of the Cloudflare dev platform, including open-source workerd JS runtime & local simulator Miniflare: https://t.co/TEPwCNzKJ1

I'm going to be speaking @NodeCongress in a few weeks to explain how this works. The organisers have kindly offered me a free ticket to give away. If you're interested in this, reply to this tweet with something you'd like to see added to the integration. I'll pick a winner soon.

If you were previously using Miniflare 2's testing environments, this new integration should allow you to upgrade to Miniflare 3. Read the migration guide here: https://t.co/u9lpo0SFq8. Given this, we'll be deprecating Miniflare 2 soon. 🥹

We built an initial prototype for this over a year ago, and it's been great to see everything come together since then. Special thanks to @sheremet_va for implementing Vitest's custom pools API, and @jasnell for building dynamic code execution primitives into the Workers runtime.

I'm proud to announce the release of the new Workers Vitest integration! This allows you to write unit & integration tests that run inside the Workers runtime. Tests run locally using Miniflare with their own isolated storage. Read the blog post below for details! ⚡️

The testing experience for @Cloudflare Workers is about to get soooooo much better 👀

We’re proud to announce the release of Wrangler v3 – the first version of Wrangler with local-by-default development, powered by Miniflare v3 and the open-source Workers workerd runtime. https://t.co/hXy10VK3nL #DeveloperWeek

@Cloudflare Many developers (myself included) started on Windows, and I'm excited that the next generation of developers will have the same local development experience regardless of which platform they're on. This has been an ongoing project for a while, and I'm glad it's now released.

The @Cloudflare Workers runtime, workerd, now supports Windows natively! 😃This means you can use `wrangler dev --experimental-local` and Miniflare 3 on Windows without Docker or WSL. Check out https://t.co/aFPTT1BF0l for more details.

Thank you for organising the meetup! Had a great time! My slides are here https://t.co/BI57l07Vvz 😀

Be sure not to miss our own @_mrbbot's talk at the TypeScript London Meetup! His talk will cover a deep-dive of how Cloudflare Workers' runtime automatically generates TypeScript definitions. See you tomorrow at 17:30 PM at Cloudflare's London office. https://t.co/oR3QuRlSdQ

😱 I'm so excited! Most Miniflare issues are behaviour mismatches, but this will allow Miniflare to evolve so it runs your code exactly as deployed. Wrangler 2 currently has remote and local modes, but we should unify these. I’ll be joining the team soon to help build this.

Hey everyone! 👋 I've just released the next version of Slshx ⚔️, a library for building strongly-typed, React-inspired Discord commands on Workers, with support for modals, attachment options and nicer error messages directly in Discord. Check it out here

Huge thanks to everyone who's tested the pre-releases, submitted GitHub issues/PRs, asked questions in the Cloudflare Workers Discord and the entire workers team at Cloudflare. 💛🧡❤️ This has been a massive project/learning experience for me, and I'm hyped for you all to try it.

Checkout the migration guide ( https://t.co/hUeizqNkD7) if you're already using Miniflare 1. I'm going to be on Cloudflare TV in a couple hours (4PM GMT/10AM CT/8AM PT) with @ashconpartovi to talk through the new features and Miniflare's history: https://t.co/0BD70gkFYt 📺

🔥🔥🔥🚀 Miniflare 2.0 has just been released, adding first-class Jest support 🤹‍♀️, live-reload ⚡️, Durable Object input/output gates 🚪, compatibility flags 📅, CommonJS module loading 📚, and so much more ( https://t.co/V7G6D90TMm), all whilst being 14x smaller than version 1.
