What if Node.js EventEmitter worked across multiple processes and machines—with zero setup?
I built Demitter, a lightweight distributed pub/sub system for Node.js.
Think emitter.emit() and emitter.on()but distributed. 🚀

Learn me some concurrency and event loop.
Is this the piece to finally give me better understand of event loop at a basic level?
Maybe try implementing something basic in @ziglang.bsky.social

Do you want to detect when code is executed with @deno.land @bun.sh or @nodejs.org ?
You maybe have seen code like `typeof Deno != undefined`, but there's a better & cross-platform way to do it.
The image shows an example, and I wrote more about it in this blog: pmbanugo.me/blog/runtime...

Express.js works faster in Node.js, compared to Deno and Bun. So if you're migrating your Express/NestJS app to Bun/Deno, run your own benchmark and be sure you're not reducing your app's performance

I'm working on a blog post to show how I (and you) can get node:http/Express faster in Node.js than it would in Bun/Deno.
What would be a suitable title?
1: Debunking the Slow Node.js server Myth vs Deno/Bun
2: Getting node:http (Express) server faster in Node.js vs Deno/Bun
3: Suggestions welcome👇🏽

It's great to talk to great builders like
@darkweak.bsky.social and @alexjoelee.bsky.social. We'll talk about building your own CDN & CDN infrastructure ( @skip2networks.bsky.social), running Caddy server as part of CDN infrastructure, and self-hosting.
Great to continue where we left of from 2024

I'm excited for this week's livestream focusing on self-hosting with @caddy.bsky.social & Souin.
We have the founder of @skip2networks.bsky.social (@alexjoelee.bsky.social) talking about how they build their CDN using Caddy, and Souin creator @darkweak.bsky.social showing us how to use Souin

Looks like this is the new way to fake commit activity for GitHub projects. I thought this project was active only to find a lot of empty automated commits and dependabot auto-merged PR.
Even the Merge commit (2nd photo) is empty commit.
