In case you missed it, here’s the recording of my talk!

Did you know this was possible with parcel? Pretty cool.

Wrote an article about how React Server Components integrate with a bundler. It's a deep dive into how code splitting works, how RSCs eliminate network waterfalls, how environment directives like "use client" work, CSS loading, etc. Check it out!

Very happy that Parcel helped enable this! 🤩

RSC support in React Router powered by Parcel! 🤩

Parcel v2.15 introduces a new HTML and SVG transformer and minifier written in Rust using browser-grade components from Firefox + Servo! 🚀 Replaces posthtml, htmlnano, SVGO, and SVGR. 10x faster. Reduces npm dependencies by 25% and install size by 45%. https://t.co/lqYHMY8Vhk

React 19.1 enables Server Components in Parcel with React Stable (not only canary)! Just released Parcel v2.14.3 with the corresponding update. 🥳

Added new Parcel React Server Components examples with Deno and Bun! You can use any server/runtime you want. Parcel just builds your code. https://t.co/kn1RGr0507

Blog post: https://t.co/LZuBK3hfDh Try it out: npm create parcel react-server my-rsc-app

Happy to announce Parcel v2.14, now with support for React Server Components! 🥳 RSCs can be integrated into client-rendered apps, server rendered, or statically rendered at build time. Also: rust MDX compiler, create-parcel CLI, new error overlay, and native import maps.

New Create React App to Parcel migration guide: https://t.co/tMGKzRt4mf Covers our new automated migration script, and how to migrate manually step by step.

Just published a Storybook Builder for Parcel! 🥳 It preserves state via React Fast Refresh in both your components and CSF story files using a custom transformer. Haven't seen this anywhere else. Hot reloading for auto-generated controls via TS too.

Just released Parcel v2.13.0! 🚀 Mostly a maintenance release (40+ fixes & updates!), but also a few nice features: 📚 New library mode that doesn't bundle, for improved tree shakability 🧑‍🍳 TypeScript proxy server config 🗃️ Globs in package.json source field 🏎️ Faster resolver

Lightning CSS v1.25.0 is out! ⚡️ • CSS module options to disable scoping for grid, animation, and other features • Optimizes the `all` shorthand • Support animation-timeline in animation shorthand • Bug fixes for transforms, color, and animations https://t.co/F8YFmIfzsP

Parcel also enables you to generate additional assets (eg css) from a macro. You can build your own statically extracted CSS-in-JS library in only a few lines of code. And since macros are just functions, you can create any API you want, eg accepting objects or theme values! 😲

tailwind-merge can be used as a macro in Parcel to run it at build time! The output is a static string, so there is no runtime performance impact and the 20kb of extra bundle size is avoided. Pretty cool! 🙂

📢 Parcel v2.12.0 brings support for macros, a new web-based REPL, improved CSS bundling, and manual code splitting! Macros are JS/TS functions that run at build time instead of being bundled. They can generate constants, code, and even assets (eg css)! https://t.co/PVCgG11H1y

Just released Lightning CSS v1.24.0! ⚡️ Support for compiling the light-dark() color function, enabling simple OS + programmatic dark mode toggles! 🌘 Also improves minification for custom properties, @​keyframes rules, system colors, and more! 💪 https://t.co/VujSL2pqmy

My team shipped the most difficult (and longest) project of my career in the last few weeks. We migrated the frontend bundler for Jira (5M+ src lines) from Webpack to @parceljs, and customers (mostly) didn’t notice.
