Heading to ViteConf in Amsterdam where I'll speak about "Building native-grade web apps with synced data". If you're there, come and say hi!✌️

LiveStore Hands-on #1: Work Squared Friday, Sept 26 @ 5pm CEST / 11am ET (tomorrow) Watch @schickling and @jessmartin hands-on with a real LiveStore app: ▪︎ Architecture review ▪︎ LiveStore best practices ▪︎ Live debugging ▪︎︎ Source available luma.com/4s7qev78

⚡ Speaker highlight: Johannes Schickling, co-founder @prisma.io Web apps need efficiency and real-time sync but traditional models fall short - Sync engines to the rescue! @schickling.dev, creator of @livestore.dev, will share how Sync Engines can transform web dev and fit right into your Vite app

I saw this tweet about @livestore.dev and it made me realize that @schickling.dev built exactly the library I need to make realtime notebooks with modern agentic plumbing. More 📘 below ⬇️

The era of manual software development is coming to a close quickly. My view on software development has drastically changed. I believe in the future the role of engineers will be to build software factories, not the software itself.

Had a great time interviewing David about how MasterClass uses Effect to build a state-of-the-art voice AI system. Really shows the power of Effect streams.

🧠 Ever heard of event sourcing? It’s the idea of storing every change as a series of events — instead of just keeping the current state. Think of it like git, but for your app’s data.

Ditto is probably the most mature sync engine out there used in airlines and other critical environments. Loved this conversation with Adam who’s the founder of Ditto and previously built Realm. Lots of great stories and insights in this episode!

I've been hoping for years that someone would build an event sourcing engine for local-first apps, and now @schickling.dev has done it! Hooray! livestore.dev

Really compelling demo by @shykes.bsky.social building a “mini Devin” coding agent in a few lines of code. Finally made the core idea behind @dagger.io click: a runtime and reusable ecosystem for your builds. Another key insight: Agents are immutable builds. 🤯 youtu.be/XWO_3My2eVU

Looking for an experienced frontend developer for a very interesting contract project (related to AI and LiveStore). Please get in touch via DM with references. (Ideally minimum of 5 years of experience.) Referrals welcome!

LiveStore is currently trending on GitHub and has already crossed 1000 stars since open sourcing this week! ⭐

We're kicking off our open source fellowship program by sponsoring @schickling.dev from @livestore.dev It might seem surprising to sponsor LS as it is a data layer that brings data closer to the UI, traditionally a server's job, and we're a server-first framework. More: rwsdk.com/blog/rwsdk-x...

Very excited to announce that I'll partner with @redwoodjs.com over the coming months to improve Cloudflare worker support for @livestore.dev

After 4 years of work, I'm incredibly excited to introduce LiveStore, the next-gen data layer I'm building for Overtone. It's based on reactive SQLite and has a built-in sync engine. Give it a try - would love your feedback!

Very excited for next week!

Move fast and sync things

Dreamweaver was such a cool product name. Would totally work today aswell for an AI builder.

When I founded Prisma, my goal was to make databases easy. Now building @livestore.dev, my goal is to make app data simple. Easy is great, particularly when getting started. But as an app gets complex, simplicity is more important. (Even more true with AI.)

Thanks for joining the 3rd LiveStore office hours! Tons of great demos, contributor demos and community questions. You can watch the recording if you missed it. Next office hours: July, 3rd lu.ma/dsmf76t4 Recording: www.youtube.com/watch?v=_VDS...

Loved my chat with @bholmes.dev. He recently built a simple sync engine from scratch which is like a "mini version" of @livestore.dev. Very fun!

Investing in good debugging practices is one of the highest leverage things you can do as an engineer. Particularly with more AI tooling and/or code written by AI. Just to name a few: - Step debugging (in VSC/Browser) - Structured logging (aiming for high signal) - OpenTelemetry

Very excited to welcome @tannerlinsley.com on the @localfirst.fm podcast today! Which questions/topics would like to see discussed?

I didn't not expect that building the devtools messaging protocol for @livestore.dev would turn out to be one of the most difficult parts to build. In order to support reliable and efficient messaging (supporting transferables), I ended up building a local networking protocol called "Webmesh".

Announcing the Local-First Landscape A comprehensive guide to help developers choose the right tools for building local-first applications. localfirst.fm/landscape

After more than 6 months of working on the local-first landscape resource together with @jessmart.in, we're getting very close to launching it. We already included many local-first/sync technologies but now is still a great time to be included. Reach out!

Anyone interested in getting early access to @livestore.dev in exchange for contributing to the docs?

Dropbox has been one of the OG local-first apps. Learned a lot about Dropbox's sync engine in this conversation with @sujayakar.bsky.social.

Event-driven design is highly underutilized. It's the right architectural approach for many systems and applications but often it's too inconvenient to do. I'm trying to fix that with @livestoredev by making the right thing easy.

I'm really happy with my M1 Max (32gb RAM) overall but man, Cursor is so memory hungry...

I highly recommend using a helper function like `shouldNeverHappen` instead of throwing errors directly in your code (only applies to defects/panics). It's an easy way to make your code more readable and improve DX by automatically opening the debugger during dev.

Our new research track is called Universal Version Control and it's about exploring how to bring the power of version control to every person, on every kind of document and every kind of collaboration. www.inkandswitch.com/universal-ve...

I'm very excited to announce that I'll be speaking at @viteconf.org about building native-grade web apps with local-first data. I'll share lessons learned and what it takes to build high-performance web apps from working on Overtone over the past 4 years.

Syncing with an existing DB can really feel like hitting a WAL.

Cursor/VSCode tip: I just changed the default view mode to "tree" for VSC/Cursor search results / source control items. (Should have done this years ago.)

Another day, another concurrency issue.

Had a lovely time chatting with Paul about when to use existing sync engines vs when to roll your own. Would love your feedback on the episode!

Very happy with my work / vibe balance!

We’re excited to welcome back @schickling.dev, co-founder of Prisma and local-first enthusiast. Johannes will unveil a new local-first data layer he’s been working on for the past 4 years.

Today we're thrilled to announce our effort to port the TypeScript compiler and language service to native code, gaining a 10x speed boost in build times and editor responsiveness! devblogs.microsoft.com/typescript/t...

@livestore.dev + @expo.dev + @cloudflare.social = Local-First app with real-time sync, offline persistence, and smooth performance. 🚀

As one of the original local-first essay co-authors, we’re very excited to announce that @pvh.ca will give a talk at this year’s conference. In his talk, Peter will share the latest about Patchwork, a new @inkandswitch.com research project.

Loading spinners are papercuts (at minimum)

Is anyone using MIDI controllers in their IDE? As a DJ this always made a lot of sense to me but with all the new AI workflows (suggestions, reviews, …) I want this modality more than ever.

I loved this conversation with Seph! He worked on Google Wave over 10 years ago which was a huge inspiration for me. Seph also recently published the eg-walker paper which we also talk about.

Took me two weeks to write 100 lines of C. Sure, I wrote a few thousand lines to test it and pages of conversation, but most of my time was spent understanding, not writing. Reminder that *writing* code is a tiny minority of the time we spend on “programming.”

LiveStore Office Hours #2 covering: - Another update on the upcoming 0.3.0 release - Devtools improvements & @solidjs.com integration - Discussion about event sourcing and migrations www.youtube.com/watch?v=Menh...

Local-first development is still evolving and may not suit every startup, but it offers real benefits. We asked @prisma.io founder and startup advisor @schickling.dev for his thoughts on its opportunities and why startup founders should consider local-first. www.heavybit.com/library/arti...

Had a wonderful chat with Adam Wulf who's behind the inspiring local-first Muse. We talked about what it takes to build software as a "team of one" and other local-first related topics including analytics and the Apple ecosystem.

With AI agents on the horizon, we'll need better authn/authz primitives to grant access to agents in a fine-granular way beyond just "Login with Google". Who is doing interesting work in this regard?
