With @EffectTS_ , telemetry comes out of the box. I just pointed an agent at logs and telemetry to diagnose a production bug and it diagnosed it and found a solution in minutes.

• Effect spans/metrics → OTel collector
• Mimir (metrics), Loki (logs), Tempo (traces)
• Grafana , dashboards + datasources 100% as code

@IbrahimElkamali @EffectTS_ Currently working on https://t.co/k4WvPd9Mku
Still very early, ideas welcomed

[Evil Rabbit @evilrabbit_]

https://t.co/udCpOYBbgj is what we use to ship shaders on https://t.co/ixOrQY1mf8. Now it's open source.

The one and only @matiNotFound did it again! Insane work!

Zero-deps has been achieved internally.

@saltyAom You convinced me - I'll give it a try in my next project

[SaltyAom @saltyAom]

Please, give Elysia a chance, I beg you

> Fastest Bun-native backend framework
> Type safety to the very limit, everything is type safe
> Prioritize on delightful developer experiences
> Multi-runtime: Bun, Node, Deno, Cloudflare Worker
> Minimal boilerplate, no ceremony, straight to logic
> Use your own validation library: TypeBox, Zod, Valibot
> Type-safe RPC-like contract like tRPC / Hono
> Easiest OpenAPI documentation of all JS frameworks
> Turns TypeScript type to OpenAPI (unique feature)
> OpenTelemetry and observability are built in
> Familiar syntax but with strong type safety
> Fully extensible with a fully type-safe API
> WebSocket, Server-Sent Event, Response Streaming
> Static Code Analysis, and JIT-compilation for speed
> Performance is near that level of Golang/Rust
> WinterTC compliance
> Can gradually migrate from Hono, Nitro or vice-versa
> No ceremony, no server required for running unit tests
> Support Bun Fullstack Dev Server (eg. React)
> The only framework that leverages most Bun APIs
> Can compile to a single binary using Bun
> Run in metaframework: Next, Nuxt, Tanstack Start
> Can even run directly inside your browser
> Deploys on Vercel, Cloudflare Worker, Docker, etc.

Other non-technical factors
> 15,000 stars on GitHub
> Has been constantly maintained for 3 years
> Research paper published in ACM Digital Library
> Been at the very start of Bun (since Bun 0.1.0)
> Interactive tutorial with grader for learning Elysia
> Documentation has an AI companion for simple stuff
> Use in several big tech companies that I can't disclose
> Hand-drawn anime girl mascot, illustration
> All of the major AI recommended Elysia for Bun
> If I were gone, I have 2 people I trusted to keep going

I've been working on contract jobs with Node for 5 years with Express, Fastify, Nest, Koa, Feather, Sails, Adonis

Elysia is designed to solve all of the issues I had with every framework I used for 5 years of Node freelancing

We don't have a company to back us like others
Elysia is run by volunteers and is completely open-source

We genuinely want a better future for JS/TS backend

The only thing we are missing is your voice
Please, give Elysia a chance

Already added several widgets like Github stars, poll, guestbook and visitors map — lots of new widgets are coming soon!

It's built on top of the amazing tools built by @convex @jamwt @jamesacowling @mikeysee @tan_stack @tannerlinsley @Cloudflare @Sentry @coderabbitai @Netlify

I've always wanted to build an infinite canvas web app— where everything can be resized and moved around in endless space.

The @tan_stack hackathon gave me the perfect excuse to finally build it from scratch.

[mateo @mateor_19]

GitBoard is the result — a realtime infinite canvas for open source projects.

Check it out in https://t.co/oIDy23hhnD

It brings new ways for open source maintainers and communities to interact with each other through realtime widgets.

This paper by @martinkl is incredibly precise: https://t.co/krRQmbRFmO

Exploring UX for the next-gen local-first apps is challenging, especially since server-first UX is so deeply ingrained in our minds

[mateo @mateor_19]

@dummdidumm_ I’ve been waiting for this for a long time 👏

The SvelteKit loader pattern is structured and easy to reason about, but it lacks flexibility. As applications grow in complexity, passing everything through the loader can quickly become messy.

[mateo @mateor_19]

@IAmWebhooked Wow this is 🔥

[jacob @jacobmtucker]

One thing vibe coders will never understand was the look on my face when I first tried @sveltejs after using React for so many years

It is so intuitive, their branding is beautiful, their onboarding is perfect and easy, and it feels so much faster

Are there Svelte vibe coders?

[mateo @mateor_19]

@jacobmtucker @sveltejs Still remember when you told me “all Emerald City projects are in Svelte”. I started reading some code and everything made so much sense.

Now, every time I have to work in a React project I miss it so much 🙈

[matia 🇭🇷 @joyofcodedev]

In the talk Rich shared a concept for SvelteKit remote functions that might become an alternative to `load` functions. 🔥

@davis7 Thanks god it finally happened, writting Svelte 5 with AI was a real nightmare

[Ben Davis @davis7]

Have been testing Claude 4.0 a ton today one Svelte & Effect code and it actually works

No other model has been able to do these out of the box, it feels SO good to finally have one that can just do it
