Svelte Radio

Kev and Jeppe, discuss the cold weather in Denmark and Sweden compared to Hawaii. They highlight that "Svelte Radio" has ranked number 13 (effectively number 12) in the podcast section of the State of JS 2025 survey, placing them among the "mainstream" podcasts and slightly increasing the pressure to produce relevant content. State of JS: Frameworks The hosts analyze the survey results for JavaScript frameworks: State of JS: Meta-Frameworks Libraries & Developer Tools Picks & Actionable Items The hosts conclude with their picks for the week: Actionable Items:

Sorry about Jeppe's audio in this one, he accidentally picked the wrong microphone during recording and there's not much we can do about it :( The gang kicks back for their first episode of the new year, catching up on holidays before diving into AI and vibe coding. Kevin talks bout a gym tracking app he built almost entirely with LLMs. They cover updates to the Svelte Society website (job board, sponsorships, newsletter), debate whether Mozilla/Firefox can survive by pivoting to AI, and wrap with hot takes: Kevin warns devs to learn AI tools or risk obsolescence, Brittney shares Claude's take that TypeScript's type system has become its own technical debt, and Jeppe champions the glory of two ultra-wide curved monitors.

In this episode of Svelte Radio, we welcome Jeppe as a new permanent host and sit down with Paolo Ricciuti, Svelte maintainer and Senior Software Developer at Main Matter, to dive deep into Svelte custom renderers. Paolo walks us through how custom renderers work (using React's approach with React DOM, Ink, and React Native as context), explains the technical challenges of bringing this capability to Svelte 5—including the template element trick, CSP issues, and runtime modifications—and shares his proof-of-concept work enabling Svelte to render to non-DOM targets like terminals and native mobile apps via Lynx.js. The discussion touches on potential use cases like Threlte for 3D graphics, the importance of this feature for Svelte adoption, and wraps up with picks including Screen Studio, TMCP, and Advent of Svelte.

In this episode, Stanislav Khromov joins the Svelte Radio team to discuss his work on Svelte Bench, a benchmarking tool that scientifically measures how well different LLMs understand and write Svelte 5 code. The conversation explores the challenges of AI-assisted coding with Svelte 5, the development of the official Svelte MCP (Model Context Protocol) that provides LLMs with documentation and auto-fixing capabilities, and the surprising performance differences between major AI providers. Stanislav also shares insights on working with AI tools, the future of local models, and the economics of AI coding assistants.

Summary In this episode of Svelt Radio, the hosts welcome Jeppe Reinhold from Chromatic to discuss the dramatic improvements in Storybook's Svelte integration. Jeppe shares how a critical video by Brittany struggling with Storybook setup sparked a complete overhaul of the Svelte experience, leading to better collaboration with the Svelte core team and significant enhancements in functionality. The conversation covers new features like Svelte CSF for writing stories in native Svelte syntax, improved testing capabilities, support for async components, and upcoming features in Storybook 10. The team also discusses the philosophy behind component-driven development, the challenges of integrating with remote functions, and Storybook's future direction including AI support and better theming capabilities.

Summary In this episode, Simon Holthausen from the Svelte team joins to discuss remote functions and async Svelte, two experimental features that are changing how developers interact with data in SvelteKit applications. Remote functions offer a new RPC-like approach that provides better type safety, more granular data loading, and improved developer experience compared to traditional load functions and form actions. The conversation covers the technical implementation, design decisions, and future possibilities including caching, streaming, and integration with Svelte's upcoming resource API. Simon also explains how async Svelte enables top-level await in components with coordinated loading boundaries, making asynchronous work much easier to manage in both SSR and SPA contexts.

Ooh, I'm joined by Brittany. Hello. Hi. Back this week. Back this week, yeah, yeah. Hello. And we are joined by another guest. It's Enrico. You might know him from this week in Svelte. Hi, Enrico. Hey, everybody. Enrico here. Hey. So before we get started, Brittany, what's new? It's been crazy. I went on vacation last week, so I know I missed our previous guest. I think we had Jacob on last week, but unfortunately I had to miss that one. We went to San Antonio where it was kind of warm. It was like 80s and 90s Fahrenheit, so what, 30? A little less than 30, maybe 20, 28 Celsius. That sounds very nice. But it was overcast the whole time. So I tried to get in the pool, and it was like windy and cold. It was like still not warm enough to get in the pool there. But we came back, and it snowed yesterday for Halloween, so that was good. We have like probably three to four inches of snow outside now. Wow. Yeah, we just got our first falling snow here today. Oh, really? So it doesn't stay on the ground, though, because it's not that cold here just yet. Yeah, our ground is not that cold. I thought it would melt, but it froze overnight, and it's just like stuck there. Damn. Yeah, that doesn't sound like fun. Maybe you should just go more south. I've talked about it, yeah. We just built that pool, though, so we're like 10 years, and our kids are in school still, so 10 years, and then we'll probably keep this house for the summer when it's nice here and then move somewhere else, be snowbirds for a while. Yeah, makes complete sense. All right, let's talk a bit more with you, Enrico. Who are you? That might be a broad question, but how did you get into development? Who am I? Yes, well, my name is Enrico Sacchetti, and I am a software developer based in the Greater Toronto area, Ontario, Canada, and what I like to do is front-end development, and ever since I was a teenager, that's what I've been doing as a personal...
