I've written something for the Sentry Engineering blog again ✨ sentry.engineering/blog/from-mo...

It's one of these days...

Well if someone has observability powers that's Santa for sure l...but you can know when they are awake too with SvelteKit otel tools. Learn how with today Advent of Svelte with Ben! 🧡 advent.sveltesociety.dev/2025/7

It's always a pleasure to host the @svelte.at meetup. Great talks, nice people and good vibes :) For @sentry.io it also pays off: We often get direct feedback we'd miss otherwise. Like yesterday, about a Svelte 4 and 5 syntax mixup in our SDK setup wizard. github.com/getsentry/se...

Last but not least we have a LT from @yuki-ishii.bsky.social, the man who put this fantastic event together! Observability in remote functions with OpenTelemetry & @sentry.io in SvelteKit! Great refresher on @stracke.tech's amazing talk at SvelteSummit

Oh... what's this, you ask? Just a benchmark that coincidentally shows how fast SvelteKit is compared to Next.js 🤷‍♂️ How fast, you ask? Just 7-10x. No biggie. Svelte ❤️

www.meetup.com/svelte-socie... See you in @sentry.io 👋

I'm excited to release the Svelte 5 course aimed at new and existing Svelte developers! 🔥 Learn how to make blazing fast web apps with Svelte and understand how it works with hands-on experience. youtu.be/B2MhkPtBWs4

It's finally out! SvelteKit users: update your Sentry SDK to 10.8.0 or later to get those nice traces. All courtesy of @ell.iott.dev and @svelte.dev. (Please let me know if I broke your app in the process)

Honored & excited! 🎉 Just joined the Svelte maintainers team (cli focus) Big thanks for the peer recognition Let's continue build cool stuff together 🧡 #OSS

Congrats to @gruntled.bsky.social and @svelte.dev for becoming leaders in o11y support in ESM frameworks! Super happy to see what I talked about at Svelte Summit becoming reality. Thanks for letting me help out out a bit along the way! Full @sentry.io support is already WIP and will ship soon!

I don't particularly enjoy type checking JS with JSDoc annotations instead of TS but it's sooo much better than working in a Vanilla JS codebase without any type checks. github.com/getsentry/se...

🎉 New Domain 🎉 🔴 New drop: April 2025 Videos 🔴 www.svelte.at/meetups/2025...

1. Receive issue with reproduction using pnpm 2. Reproduce the issue 3. Change repro to a sane package manager (npm, yarn@1) 4. No longer reproduce issue Happens to us ~once per week. Question is: Is it a Sentry SDK problem? Or is it pnpm? Do I need vacation? Guess which question I can answer

I want an AI assistant that tells me honestly "I don't know" instead of making up garbage to seem all-knowing. AI really shouldn't mimic all human traits :) Don't know the type of this function? Tell me or leave it blank, but don't bs me. That's the only way I'd ever trust these things.

🎉 Tadaaa 🎉 vite-plugin-kit-routes 1.0 is out 🎉 A/ add the vite plugin B/ enjoy route typesafety ! Easy ?! More here: www.kitql.dev/docs/tools/0...

My #sveltesummit talk was published today! I talked about using @opentelemetry.io in SvelteKit apps and what the framework can do to make this a better experience.

Had the honour to talk about tracing with OpenTelemetry at @svelte.dev Summit and what I think meta frameworks like SvelteKit can do to help making this an easy experience for everyone. More than happy to help making this a reality! Kicked off a discussion here: github.com/sveltejs/kit...

Really looking forward to Svelte Summit and meeting lots of Svelte Enthusiasts! Please come say hi at the @sentry.io booth :)

Kinda funny when the tool you're working on becomes so good (team effort!) that a competitor 1:1 clones it and bases their work on it :D

Had some time to build a little CLI E2E testing utility that can be used with arbitrary test frameworks. All of this is a heavy WIP but what do folks think about this scenario builder approach?

What happens when your SvelteKit app slows down? Lukas Stracke @stracke.tech will show you how to trace bottlenecks with OpenTelemetry—and why it’s trickier than you’d expect. Catch this at Svelte Summit Spring 2025!

Micro frontends regularly make me want to quit my job

Cabin crew, prepare for release! 🚀

GitHub users who open an issue with an actual minimal reproduction in a repository, that I just need to clone to reproduce, should receive a special award. Makes my day every time!

Now that speakers have been selected we want to share with you our line-up for Svelte Summit Spring 2025! We will host 16 talks across different topics during the two day conference. In addition, @mainmatter.com will also host a workshop. More details on www.sveltesummit.com

MICROFRONTENDS ARE THE ASBESTOS OF OUR GENERATION

While ESM is awesome, we're still missing a user-friendly approach for observability instrumentation. The ecosystem needs a standard way to instrument ESM modules without friction. I summarized the challenges and potential solutions here: github.com/getsentry/es...

My recent PR to SvelteKit was merged in record time - on the same day I opened it! Thanks a lot @dummdidumm.bsky.social 🙏 I hands down think that @svelte.dev Kit has the cleanest code base I've ever seen. Super easy to understand what’s going on which in turn makes it easy to contribute.

I had a great time at @viennajs.bsky.social talking about mutation testing and my experience of using it in our Sentry JS SDK repo.
