With React Native AI, you can choose the right provider for your use case: - Apple provider → system models built into iOS - MLC provider → run any supported model locally

You know that @chmal.it is cooking 🧑‍🍳 with Rozenite. He's in Prague tomorrow doing a deep dive into React Native DevTools. Ever wondered how they actually work? He reverse-engineered the whole thing and built a plugin framework around it.

So, as far as Bluesky goes, I think I will have to split my video up into even smaller chunks 😂

You know it's a good rewrite coming up! AI space is pretty interesting. Everyone's building AI agents and AI agent frameworks right now. So many different approaches. Everything changes each week. Decided to focus on building some production workflows, hopefully this is the last one 😂

React Native Fast IO is out there on `npm`, latest version `0.2.0`. If you're building something with WebSockets in the next few weeks, I'd love if you could give it a go! [link in thread]

Meet Fabrice AI - functional framework for building AI agents. While building Cali, I needed something stateless that can work on the server, inside CLI, breakdown complex tasks, and be simple. Couldn't find one, so I built one. Give it a try! github.com/callstackinc...

Dropping something new early next week. Came up with the idea while fixing another library. It's recursion and I am unwinding now 🤣

BTW, if that's too many questions, just be more specific, if you know what to do 🥳 The beauty of an LLM with function calling here is that it can adaptively adjust its control flow to your environment, something that we were never able to do in the CLI.

What if React Native CLI was an AI agent? Meet: CLAI 😂💻 Just put up this POC yesterday. No control flow, just prompt and tools. The promise: easier debugging and troubleshooting. Going to fix UI and put it up on `npm` later today. Any last minute requests or thoughts 😂

Today was very emotional day. Around 20 years ago, I listened to the first Lennon song, then I dig through the entire discography to realize I’ll never get a chance to hear him live. Back then, I could only dream of visiting Strawberry Fields and Dakota House

Today’s United aircraft is 32 years old. Was a bit worried, but it does feel great and spacious. Love flying because it’s one of those rare moments where time DOES NOT fly and it’s completely distraction free! (After you catch up with all the shows)

🎉 As promised, next update on my library: > Fetch now supports sending ReadableStreams and Blobs. What's does it mean? ✅ No data loaded into memory. File is streamed straight from the storage ✅ File extends from Blob and as a result, has properties such as `stream()` or `bytes()`

Mike @grabbou.com · 06/11/2024
Coming soon to React Native. First-class support for streaming data. What this is? ✅ Create readable/writable streams from both jS and Native ✅ Consume streams from both JS and Native ✅ Works with WebSockets, fetch and more... 🔥 Build on top of Nitro Release in 9 days... @rnlconf.bsky.social
