🏖️🦀TanStack Start + Rsbuild is a win-win for both communities 🤝 Rspack users get a full-stack choice: 100% TanStack Start, with router, SSR, RSC, Server functions out of the box TanStack users can adopt the Rspack toolchain for stable bundled dev and first-class MF support

Big day for the Rspack ecosystem! 🎉 TanStack Start is an amazing full-stack framework, and Rspack users now have a first-class full-stack option. Huge thanks to the TanStack team for shipping this so fast and so well. 🫡 tanstack.com/blog/start-a...

Say goodbye to import.meta.webpackContext 😉

🦀“import.meta.glob” is now available in Rspack Import multiple modules from the file system with glob patterns One consistent glob import syntax across Vite, Turbopack, and Rspack

Turborepo now has a guide for using Rsbuild in monorepos, including examples that cover Module Federation. Big thanks to @nstlopez for the PR!

Just enabled npm staged publishing for 50+ packages, including Rsbuild core / plugins. Staged publishing adds a 2FA approval step before a package goes live, helping reduce the risk of unauthorized releases. Security matters to Rstack, and we’ll continue enabling it for more packages.

@rspack/core is now 2.6 MB smaller than the previous release, and 17.8 MB smaller than v1.0. Love the new npmx graph for visualizing this trend. 📉

🌲Rspack's tree shaking just got smarter 🦀 Two recent optimizations remove more unused code: 1. Inlined booleans can make branch-local dependencies inactive 2. Namespace default re-exports now preserve property-level usage More precise bundles, less dead code

Do you know that using GitHub CLI (gh) may expose you to supply-chain attacks? It stores a long-lived GitHub token on your machine, which can be stolen by any malicious scripts. This is what happened in the recent Nx supply-chain compromise, which led to GitHub’s source code being leaked.

In the next release, Rstest supports "using" too

Rsbuild now supports `output.autoExternal`. Previously only available in Rslib, it automatically externalizes dependencies from package.json. It can now be used in Rsbuild for SSR, Node.js apps, and more.

❓Did you know you can write “in-source tests” in JavaScript Rstest supports in-source tests — write your test right next to the code. Test code is stripped in production builds. Zero bundle cost. ⚡️ Rust-style DX, now in your JS toolchain 🦀 #JavaScript #Rstest #Rspack

Rsbuild now supports Vite-compatible worker query imports, including `?worker` and `?worker&inline`. Inline workers can be useful when you need to avoid cross-origin restrictions.

Today's two supply chain incidents are likely connected: 1. `actions-cool/issues-helper` was compromised 2. AntV was compromised shortly after I noticed AntV was using `actions-cool/issues-helper@main` in GitHub Actions.

Rstest is getting more mature, with solid performance and seamless integration across the Rstack ecosystem

🦀Rstest 0.10.0 released! 🚀 Faster. Leaner. More reliable~ ⚡ worker_threads-based pool 🎯 --changed / --related test runs 💾 Persistent build cache 🧠 Memory-aware worker spawn 🔇 Silent passed test consoles 🔍 Profile test runs with --trace

Rsbuild CLI just got ~10-20ms faster on macOS. The change was small: removed `process.title = "rsbuild-node"`. We originally used it to make Rsbuild processes easier to identify during profiling, but the native call adds measurable startup overhead 😂

Large-scale AI migration is changing how we think about rewrites. Looking back at Rspack, rewriting webpack in Rust was never just about translating code. When we rewrote webpack in Rust, many of us were still learning Rust, webpack internals, or both. The project itself became a training ground.

Things get wild when @hardfist1.bsky.social uses Codex. He just made SWC parser 20% faster and minifier 10% faster 🤯

Released eslint-rspack-plugin v5.0.0 🚀 - Rewritten in TypeScript - Pure ESM package - Install size reduced by 91% - Drop ESLint v8, flat config by default - New severity option

🦀Rspress v2.0.10 ships a built-in <Prompt /> component Add a one-click AI prompt to your docs with Rspress: - create a new project - pick the right template - run the setup commands - ... AI-native documentation, made easy

I love how the rs prefix makes all our config files stay neatly together

🦀 Install any of Rstack Skills instantly: ``` npx skills add rstackjs/agent-skills --skill <skill-name> ``` 15+ Skills covering debugging, tracing, upgrading, and analyzing

In the next release, Rspack is 7% faster than v2.0.0 🚀

Shakapacker now supports Rspack, giving the Rails community another option for modern frontend builds. It's great to see Rspack becoming more accessible across different ecosystems.

Making posters with GPT-image-2 is just too easy

Rsbuild 2.0 is out too! 🦀 Powered by Rspack 2.0 🎁 Pure ESM package ⚡ Fewer deps ⚛️ RSC plugin I'm especially excited about the upcoming support for TanStack Start. 🔥 Read more: rsbuild.rs/blog/v2-0

Rspack 2.0 has landed 🦀 The growth since 1.0 is wild: 📈 100K → 5M weekly downloads ⚡️ ~100% faster builds 📉 devServer: 192 deps → 1 And new stuff hits hard: 🧩 Pure ESM core, modern ESM library output ⚛️ Experimental RSC support ... Lean, Fast, Modern Web Bundling 🚀

Node.js 20+ and TypeScript 6.0 now let you write subpath imports with a bare "#/*" prefix. Rspack supports it too — so you can map "#/*" directly to ./dist/* (or ./src/*) Clean, familiar, and one step closer to the "@/" bundler experience 🦀 #Rspack #WebDev #JavaScript

Rspack / Rsbuild 2.0 stable is coming next week! One key improvement: we've trimmed npm deps across core packages to the bare minimum. This lowers supply chain risk and speeds up installs.

Setting up Rstest just got easier. Rstest docs now include a dedicated guide for coding agents to do it for you:

Just tried "rslint --type-check": 2s for type-aware linting + type checking on the Rsbuild monorepo 🚀

Rsbuild reached 1M weekly downloads. Thank you all ❤️

Lots of ecosystem and community updates, too: ⚡ @vite.dev 8 ▲ @nextjs.org 16.2 📝 @eslint.org 10 🅰️ @angular.dev 21 🦀 CLI init support for Rsbuild ⚡️ @preactjs.com support for Vitest addon 🤘 Community @vike.dev integration 🚀 Community @astro.build framework (experimental)

Here's what we reached for 👇 → Lit and web components for all interactivity → Custom server components for static templating → Rspack instead of Webpack → Declarative Shadow DOM for instant rendering → Baseline to decide which web APIs we can ship with confidence

Update: reduced @rspack/dev-server deps from 193 → 8, install size from 14.9 MB → 4.1 MB. npm supply chain attacks keep happening and keeping deps minimal makes me feel safer.

Some recent Rspack benchmark trends. Rspack 2.0 work is helping improve performance steadily⚡️

We’re getting close ⏳ Rspack 2.0 and Rsbuild 2.0 are landing next month. Beta is already out. give it a try and share your early feedback with us.

Rstack could offer a unified toolchain experience similar to Vite Plus as well, and huge respect to the Vite Plus team for exploring that direction. We haven’t pursued that path for now, mainly because we worry about a few tradeoffs:

New doc added: Rspack + AI 🤖: rspack.rs/guide/start/ai Learn how to use coding agents to set up and work with Rspack projects more efficiently.

Working on modernizing Rspack dev server. No longer tied to webpack-dev-server compatibility. Dependencies are updated and unnecessary ones removed. Early progress: 📉 Direct deps: 28 → 9 📉 Transitive deps: 193 → 76 📉 Install size: 14.9MB -> 9.9MB

Rspack just hit 4M weekly downloads. Vibe coding is helping dev tools grow faster. 🚀 0→1M: 750d 1→2M: 160d 2→3M: 140d 3→4M: 40d

Remotion is working on experimental Rspack support 👀 github.com/remotion-dev...

Great to see Tailwind CSS shipping an official @tailwindcss/webpack package 👏 It’s implemented as a webpack loader, which means it works in Rspack and Turbopack as well. Big shoutout to @timneutkens.bsky.social for making this happen 🙌

Chinese New Year is coming, so our team managed to get a few releases out 😂 Rspack 2.0 beta, Rsbuild 2.0 beta, Rspress 2.0, Module Federation 2.0 stable, Modern.js 3.0…

Smaller Module Federation bundles are here! Rspack 2.0 supports tree-shaking for shared code 🔥

Nice! Also remember to like @rspack.dev on @npmx.dev! 😊 I got the first like! Again thanks for your great work!
