Developer @ByteDanceTalk, project lead of Rsbuild / Vant.

Working on @rspack.dev (Rspack, Rsbuild, Rspress, Rsdoctor, Rslib, Rstest, Rslint).
Rspack has tons of complex tests. We just migrated from Jest to Rstest and saw about a 30% speed boost. ⚡️

If you’ve been thinking about trying Rstest, now might be a good time to give it a shot.

create-rsbuild now automatically generates an AGENTS.md file to help coding agents develop better. 🤖

Still early, but we'll keep improving it and bring AGENTS.md to all Rstack scaffolds soon.

Rsbuild dev server got a small boost:
⚡️ Startup 10-20 ms faster
⚡️ HMR 5-10 ms faster

In the next release, Rsbuild will forward browser errors to your terminal — giving your coding agent more context 🤖

Rslib v0.13.3 is ~100ms faster from a tiny change:

Swapping import "typescript" with require('typescript').

It skips Node's cjs-module-lexer overhead. 😅

We should make this

Tried out Rslib with tsgo… my package builds got 2.5x faster 🔥

Now I work with tsgo locally, but CI runs on TypeScript 5.x — more stable that way.

Rslint logo is a little crab holding a ruler, because linter is all about rules 📏

Super excited for the upcoming Rsbuild 1.5. We're enabling several Rspack experimental features by default:

⚡ Barrel file optimization → faster builds
✨ Lazy compilation for dynamic imports → faster dev startup
🎯 Inline const for TS enums → smaller bundles

Rspack/Rsbuild v1.5 Beta is here with faster builds 🚀Especially noticeable when building larger applications.

Spent the day migrating all Rsbuild npm packages to npm's new trusted publishing feature. Simple setup, no more long-lived tokens needed. Love it! 🥰

Rsbuild's next release will reduce startup time by ~25ms 🥳

Rsdoctor MCP collects build data from web apps, transforms it into structured data, sends it to LLM, activates the huge webpack optimization and debug knowledge contained in the model, and finally outputs practical optimization suggestions.

The Rstest logo has just been finalized 🪄🦀✅

The binary size optimization in Rspack 1.2.8 is pretty sweet

Rsbuild has been added to React's CRA blog and build tools guide, thanks to the React team!

20 months ago we celebrated Rspack being open source at Universal Studios, and today we're celebrating Rspack reaching 10,000 🌟 at Disney.

npm just fixed their downloads and Rsbuild hit 100k weekly downloads 🥳 The number was 3k at the same time last year.
