Yesterday was all about animations. Today, let's talk multi-threading and Worklets 0.13! We improved startup time, ported Babel plugin to Oxc, added stable networking APIs and, most importantly, opened an RFC to upstream our multi-threading code to RN. More in the thread 🧵👇

🦀 Shoutout to @tshmieldev, who ported our Worklets Babel plugin to Oxc. You can use it to save a lot of bundling time. It's available both as a Babel wrapper and standalone. Here's how much CPU time it saves when bundling our example app. docs.swmansion.com/react-nat…

I'll be speaking at ReactCon Berlin this October! If you're crazy about low-level stuff like me and want to know just how much overhead the JavaScript layer adds in React Native apps, don't miss my talk!

Best CI use case for @typesafeai's Jev: Enforce the rules a linter can't every repo has rules that only live in review comments and onboarding docs softlint puts them in a json file and checks every pull request against them, flagging the exact line any language, ~$0.001 per PR it's open source, link below 👇

Trying to visualize the benefit react-native-worklets It's not super readable and needs polishing but it looks amazing already 🤩 This simulation is actually executing the code snippet, we could add it for free on every Worklets' docs page explaining how a given API works 🤓

Is this Native or React Native? Both. Core Animation is coming to layout animations in React Native Reanimated. Stay tuned!

This "benchmark" gives additional warm up to agent-device, but gives no such thing to Argent, the following is literally copied from this PR: if tool == "agent-device": prepare_agent_device_daemon github.com/software-mansion/…
