Had some great Vietnamese food and an even better conversation with @yang_mingshan.
I first came across @yang_mingshan about five years ago, when I was learning about WeChat Mini Programs. Back then, I never thought we’d ever have any reason to cross paths.
And somehow, five years later, we ended up meeting in Singapore today.
Life’s funny like that :)

@rolldown_rs has a new RFC: "Progressive Module Runtime and codeSplitting.inlineCommonChunks"
This is a fundamental enhancement to Rolldown's chunking capabilities. It allows Rolldown to reduce the number of small chunks by inlining them into the entries that consume them.
Since this changes chunking behavior, it may also have an impact on the @vite_js ecosystem.
We'd love your feedback. Please leave your thoughts in the discussion:

Happy to share that we've finally resolved one Rolldown's earliest issue related WASI.
We now run Rolldown's full test suite against the WASI target.
Huge thanks to @napi_rs and the man behind @Brooooook_lyn — the DX is so good that adding WASI support feels almost like just another build flag.

I polished the Project Context Records README and added a diagram to illustrate the workflow.
I now use PCR for pretty much any long-running task I want an agent to tackle autonomously, without constant supervision.
The whole methodology is simple enough that all you need to do is copy a single block of text into your AGENTS.md file.

Been digging into perf on vinext.dev lately, and the early numbers are wild.
- Production build time drops 32–52%
- dev-server cold start 67–83%
and it scales! the bigger the app, the bigger the win.

Bun's react compiler uses @OxcProject under the hood!
In the next version of Bun
`bun build --react-compiler` runs the React Compiler in Rust
On a large React codebase, it's 19x faster than the Babel plugin
ALT Wall time vs Babel plugin Baseline ( reactCompiler: false ) 391 ms - reactCompiler: true 484 ms 19.8x faster Babel plugin (same input) 9.58 s 1x

Spent a day designing a loop prompt, followed by 24 fix/perf commits over two days to @OxcProject. Shoutout to @Cameron_C2 and @leaysgur for coaching me on my PRs!

Recently I've been using a small methodology I call:
"Project Context Records".
Most of what matters about a project never makes it into the code: the decisions, the trade-offs, why it's built this way. It stays in your head, and an AI agent starts every session without it.
PCR keeps what lives outside the code, the decisions and trade-offs behind it, in the repo.

Oh and I did end up building the coding agent. It's in the examples. ~200 lines of Vue, one bash tool, powered by DeepSeek. It keeps insisting it's Claude though😂.

The Flappy Bird example is one .vue file. Reactive state for physics, <Box> with borders for pipes, useInput for controls.

I wanted to build a toy coding agent. Started by looking into the TUI layer. That rabbit hole turned into a full terminal UI framework.
- Write Vue components for the terminal.
- Develop them with Vite HMR.

In the next version of @rolldown_rs, I managed to get 20 kg off team member @_hyf0.
This should greatly improve its long-term maintainability.

POV: my boss in build mode the past two weeks.
Besides VitePlus, something else starting with V is coming soon🫣.
I think I am designing something truly unique right now... I might be too high from the continuous dopamine hit from agents turning my crazy ideas into code in 10 minutes. But like this is genuinely good stuff.

In the next version of @rolldown_rs
Up to 9% faster bundling by optimizing how file paths are handled internally.

In the next version of @rolldown_rs.
```
rolldown --moduleTypes .node=copy
```
Copies matched modules as-is, emits them to the output directory, and rewrites imports to reference the copied file.

Good job! We're building something for tsdown using Node.js SEA!
Landed initial ESM support in Node.js SEA: github.com/nodejs/node/pull/…
Similar to CJS entrypoints, it currently can only import builtins, so generally require bundling. Though @matteocollina is working on support for VFS in SEA that will unlock loading other modules within SEA

Another contribution that makes your claw tons faster by using builtin `JSON.parse`😉!

I kept running into the same annoyance: every time I wanted to open VS Code when using claude code, I had to spin up an extra terminal just to run `code ./`.
So I built a `/code` skill that lets the coding agent open VS Code for the current project directly—no extra terminal needed.
Quick install: npx skills add hyf0/skills -g --all --skill code

Callback from 2026: After reading the article, I successfully compiled @vue/compiler-sfc into C and called it from Rust!
Wrote a blog post with more details about how I compiled Less.js into a C library with Static Hermes and called it from Rust. You know, for science! 😃 devongovett.me/blog/static-h…
