What you’ve been doing is really valuable. I’ve learned to mostly ignore AI spam and save my time and energy for genuine users

Lots of “OSS is dead” talk lately. Being a maintainer can feel like more stress than fun, so seeing these numbers grow is a nice little boost to keep going

Haha, maybe we should try the Sentry codebase and see what optimization opportunities we can find

Jiahan Chen @chenjiahan.bsky.social · 29/09/2026

We’re putting more focus on memory usage in Rspack and Rsbuild, especially for large codebases or when running multiple agents in parallel. Recent optimizations reduced peak dev memory by 19.5% in one large project, with faster startup and rebuilds too

Rspack's code splitting balances bundle size, chunk count, and build time. The next release adds `splitChunks.dedupDepth` to spend more time finding shared code and reducing duplication. In one real-world app with many routes, using this option cut total output size by 9.9%

We recently upgraded an internal monorepo from Rspack v1 to v2. Build time dropped ~45% Then we noticed the repo had added 4 million lines over the past 6 months. About 80% was TS, mostly written by agents Still plenty to do to keep Rspack and JS tooling fast enough for agents

SWC's binary just got 2.4MB smaller. Rspack and Turbopack could benefit too. Thanks @swwind233 for the optimizations

Great to see Vercel contributing to React Compiler's Rust implementation! Official crates are now available, so SWC and Rspack have switched from forked crates to the official ones.

Today, Rslib 1.0 is here and already powers thousands of libs. Quite a journey!

Jiahan Chen @chenjiahan.bsky.social · 04/09/2026

We originally built Rslib to unify ByteDance’s web apps and JS libs around Rspack. Getting there wasn’t easy. Rspack inherited an architecture primarily designed for bundling apps, so we made many improvements to produce clean ESM for libs.

Excited that TypeScript will finally support module types based on import attributes! Bundlers and frameworks can now provide accurate types for custom imports:

Jiahan Chen @chenjiahan.bsky.social · 28/08/2026

Interesting to see ESLint exploring a unified JS/TS parsing toolkit. Our approach in Rslint is to treat the TS 7 parser/compiler as the single source of truth. Linting and type checking share the same program, so each file only needs to be parsed once, and its AST can be reused

Jiahan Chen @chenjiahan.bsky.social · 27/08/2026

Cool to see Sentry already trying Rspack 2.2's new compact ID strategy, cutting gzipped JS by 152KiB. If all goes well, it'll be the default in a future minor release. We made a silly API typo and used "compat" instead of "compact". Guess we'll support both names😂

And Rstack ecosystem keeps shipping: 🦀 Rsbuild — Solid v2 support, Octane template 🦀 Rstest — Playwright E2E, Module Federation 🦀 Rslint — 500+ native rules, JS API 🦀 Rslib — TypeScript 7 support, v1.0 soon 🦀 Rspress — 100/100 agent-friendly score

In the next release, Rsbuild will enable chunk splitting by default for Node.js builds. This reduces duplicate code across chunks and makes SSR apps more efficient. The benchmark below is a TanStack Start stress test case with many routes and shared modules:

• Composable: Loaders can be combined and ordered as needed to build flexible transformation pipelines • Cacheable: Loaders are usually stateless, making their results easy to cache and reuse • Portable: The same loader can run on webpack, Turbopack, and Rspack

Jiahan Chen @chenjiahan.bsky.social · 14/08/2026

I used to dislike webpack’s loader design, but over time I’ve come to appreciate just how much it gets right: • Easy to parallelize: Loaders are standalone modules, so they can run in workers with little effort. I saw Rspack’s parallel loader feature cut babel-loader time by 80% in one large app

Building a library with WebAssembly? 🧙🏻Rslib 1.0 beta supports `.wasm` imports with two output modes for different consumer needs: - `compile` adds runtime loading glue - `preserve` keeps the import for the consumer's bundler Simple source. Consumer-ready output. 🦀
