Re.Pack

I just released fast-flow-transform 🚀 If Flow is the last thing keeping Babel in your pipeline, this is for you. It strips Flow syntax natively, so the rest of your pipeline can stay on newer tooling built around SWC or Oxc. Published benchmark: ~20x faster than Babel.

After a three-year break, Agent Conf is back: reimagined. Born as a beloved React conference in the Austrian Alps, we’re opening a new chapter in Warsaw. This time focused on the next frontier of software: AI Agents. agent.sh/?utm_campaign=…

We've just released 𝚞𝚙𝚐𝚛𝚊𝚍𝚒𝚗𝚐-𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎 skill ✨ ~/ npx skills add callstackincubator/agent-skills

Been working on adding @repack_rn support to React Native @storybookjs and the first working version is in v10.2.2-alpha.3 🎉 Use the Storybook plugin to handle configuration, and the agent setup skill now knows how to configure Repack projects too.

🚨 If you're using babel-swc-loader, you should consider upgrading to newly released Re.Pack 5.2.3 We fixed the configuration handoff for transform-react-jsx from Babel to SWC, resolving compatibility issues with libraries like NativeWind. Release notes: github.com/callstack/repa…

In Re.Pack 5.2.1, when using babel-swc-loader, we fixed determining the correct module type: SWC now inherits it from Babel. We've also fixed Module Federation emitting unnecessary chunks in production, making the final output smaller 🚀 Release notes: github.com/callstack/repa…

@thiagobrez @ChmalSzymon Do it @ZephyrCloudIO

@ChmalSzymon I can't get it out of my head to make a plugin to manage / invalidate / replace @repack_rn federated modules 👀

Using the mediator pattern in your app to break it into independent modules? Struggling with observability? This is the perfect case for developing an in-house Rozenite plugin that lets you inspect messages passed between modules in real time.

Module Federation Metro Plugin working in Expo Go ✨ up next: @expo development builds 👀

React Native OTA updates at scale at Klarna by @adam_mruk with Re.Pack @repack_rn 🔥

Just resolved an issue where the new babel-swc-loader in @repack_rn was performing poorly. From 115.4s → 2.6s 🔥 Turns out it was a 100k+ lines prebundled lib that was getting processed by a single Babel worker 🤯 Delegating this to @swc_rs decreased the build time 40x!

Re.Pack 5.2 is out! Lots of goodies in this one: ⚡️ babel-swc-loader for fast & universal transforms 👮‍♂️ Typed configs for Rspack/webpack 📱React Native 0.80 & 0.81 support 🛠️ Rozenite DevTools integration ✨ Updated dev mode progress reporting Read the full release blogpost 👇

My first actual code contributions to @rspack_dev just got merged 🎉 Parallel loaders is an exciting feature, especially for Re.Pack where we mix babel & swc Thanks to Web Infra team for quick handling of these PRs 🙏
