Another huge release! Absolutely killing it svelte team

Effect v4 is here. One ecosystem. Zero dependencies. The next chapter of Effect and the foundation for building reliable software and AI agents in TypeScript. Read the full announcement below: effect.website/blog/release...

Put together a list of some of my favorite dev tools with my ViteConf 2026 mission credential. Create yours! viteconf.org/tickets/t/Pv...

Saw some people sharing and found it a fun concept. Lots of the trips here are all by road transport, think of the miles!

Cannot wait to go through my repositories and update for that speed!

TypeScript 7.0 Beta is here! Built on a new native and parallelized foundation, it's already being used on multi-million line codebases. Read up more here and try it on your projects today! devblogs.microsoft.com/typescript/a...

Today, we launched Effect v4 beta 🚀 Rewritten runtime. Smaller bundles. Unified package system. Performance: v4 is faster and lighter than v3 across the board. Rewritten runtime: lower memory overhead, faster execution, simpler internals. Full announcement: effect.website/blog/release...

🆕 npx unbarrelify At last, an easy way get rid of barrel files! Rewrites consumers to import directly from source, then deletes the barrels. Safe and fully automated, read all about it at github.com/webpro/unbar...

If you haven't tried Sveltekit yet this is a good starting point with some of the new features coming soon!

Can't wait!

My new music video goes out on YouTube at 3pm UK time today. To every developer out there who has ever been asked to do something really, really simple that turns out to be impossible because there is Too Much Architecture in the way: this one's for you. 🤘 www.youtube.com/watch?v=p03o...

What an awesome enhancement to @vitest.dev v4. It includes standard schema integration, but also browser mode is no longer experimental!! 😁 vitest.dev/blog/vitest-... Seriously try out browser mode!

Feel a bit nervous but excited about @effect-ts.bsky.social, this video crash course covers lots of the what's and why's. youtu.be/MyOOulMjLm8?... Thanks Jesse W, he even shares the slides 😎

If you haven't heard you can now try out @effect-ts.bsky.social's v4 preview!! I'm no effect wizard but am excited to see what they have been baking! github.com/Effect-TS/ef...

SvelteKit's remote functions now handle FormData out of the box! github.com/sveltejs/kit...

svelte.dev/packages is now live! It's a convenient and easily discoverable place to find a sampling of high quality packages in the ecosystem. We hope it will give confidence in the Svelte ecosystem to newcomers and help them get started more easily.

I love that you no longer have to do the form data dance in SvelteKit thanks to remote functions 🔥

It's that time of year, get your best typing fingers out and head over to fill out the state of JS survey! survey.devographics.com/survey/state...

An Interactive Guide to TanStack DB | Frontend at Scale https://frontendatscale.com/blog/tanstack-db/

If you haven't seen any of his content or have an interest in svelte, please go watch this updated course!

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)

✍️ New post on the @nuqs.47ng.com blog: Type-safety for URL state is only the tip of the iceberg. Beware of the dangers below. 🧊🚢 - URL limits - Time safety - Immutability nuqs.47ng.com/blog/beware-...

What a super useful feature to have built into your validation!

OpenTelemetry tracing is live in SvelteKit! Huge s/o to @stracke.tech for all the help along the way. SvelteKit can now emit OTEL spans for all of its serverside constructs. It also provides an instrumentation file to easily set up trace exports. svelte.dev/blog/sveltek...

I wanted to release the Svelte 5 guide later since I was thinking about interactive examples but here you go if you like reading and I would love your feedback as I work on the video. 😄 joyofcode.xyz/learn-svelte

What an amazing video! If you are any way interested in Effect peek at it!

pnpm v10.14 is shipped with support for runtime engine installation. Node, Deno, and Bun are supported. pnpm.io/blog/release...

Effect: the unreadable library that captured my heart By Matt Pocock @mattpocock.com youtu.be/S2GChOwivwQ?...

Best intro slide today! #reactsummit

Loved the RSC talk by Tanner, I've used Start and it's great. Take a small project and at least use Tanstack Router as it is so amazing having URLs as state! Thanks #reactsummit

Enjoying the talks at #reactsummit! Thanks to all the MCs and supporters!

If you have a bit of time and are interested in @effect-ts.bsky.social this is a great intro to Effect resource! Thanks so much @sandromaglione.bsky.social!! www.typeonce.dev/course/effec...

Shameless plug, I've built secco.lekoarts.de for this problem :) It copies files to node_modules or publishes to a local Verdaccio instance if necessary.

*sigh*

From zero to confident testing in Effect – in four recipes. Edouard Penin, Senior Engineer at evryg, shares practical patterns for testing real-world scenarios with Effect. Watch the full talk from Effect Days 2025 below: www.youtube.com/watch?v=pIXX...

Had a great time speaking today about Svelte and SvelteKit at a JS meetup. The interest and those that use (from a hand raising) was similar to that found in the State of JS 2024 survey. Thanks all who attended and had some excellent questions!

Impressed to see the success and speed Prisma is adopting TS over rust to reduce memory transfer between languages. Resulting in a performance lift! Also good to see it available for public testing. New "Rust-free" Version of Prisma ORM (Early Access) - Check it out here: prisma.io/blog/try-the...

Got my sticker pack in from syntax. Thanks for sending these! Also the news letter is great! @syntax.fm

Seeing more and more devs talking about ArkType but not sure why you'd switch from Zod? This video is an *excellent* overview of what you're missing out on. www.youtube.com/watch?v=Jgcs...

Why not let Deno help you scaffold and deploy with their LEET HEAT and amazing dev experience!

Here's it 🔥 github.com/runreal/deno...

Zero Sync is a game changer. You will be shocked at how fast it is. This is the type of new tech that really moves the needle to more native feeling web apps. Zero Sync Makes Local First Easy youtu.be/hAxdOUgjctk

> When bundling all eight libraries together, @vite.dev is the winner, with the output size of 2087 KiB. Comparing it to the largest output size of 2576 KiB, that's over 23.5% smaller output. Fantastic post from Filip. If you're working on a big web app, you'll surely find some ideas to improve it.
