PR Summary

Medium Risk
Parser and AST visitor changes in type-annotation linking could alter behavior for edge-case TypeScript types if yuku’s output differs from OXC.

Overview
Replaces oxc-parser (and its native optional bindings) with @yuku-parser/wasm and yuku-ast for TypeScript parsing in metadata type resolution.

In resolveTypes.mjs, batch alias parsing now uses parse(source, { lang: 'ts' }), treats diagnostics instead of errors, and walks the AST with walk instead of OXC’s Visitor. TSNullKeyword is handled via the shared keyword list; the old TSLiteralType / NullLiteral visitor path is removed.

Package version bumps to 1.4.3 with a patch changeset noting the dependency swap.

not fan of yuk-parser too recent and zig

araujogui · 2026-07-19T21:42:27Z

What's the advantage of yuku-parser compared to oxc?

avivkeller · 2026-07-19T21:45:12Z

It doesn't crash the Node.js CI by requiring a native binding for niche platforms :-)

bmuenzenmeyer · 2026-07-20T02:15:52Z

I feel the same as above - never heard of it and want to more thoroughly vet something going into core CI

avivkeller · 2026-07-20T02:49:38Z

I can switch to swc, but Yuku claims to be much faster:

avivkeller · 2026-07-20T02:51:24Z

IMO there's nothing wrong with using a smaller package, it's spec compliant, and this gives us the opportunity to work with other maintainers :-)

bjohansebas · 2026-07-20T03:11:12Z

My only concern is who's behind the project—I mean, whether it's going to be maintained in the long run. At least with OXC, it's pretty clear it'll continue to be maintained, and the same is true for SWC because companies have a vested interest in it.

Whether it's written in another language doesn't really matter to me. What matters is who's maintaining it and what their long-term plans are.

bmuenzenmeyer · 2026-07-20T03:25:49Z

I tried to check out their openssf scorecard, only to find https://github.com/yuku-toolchain/yuku/security - agree it looks fast, but we need HIGH SCRUTINY on every dep, in my opinion

avivkeller · 2026-07-20T05:14:09Z

So do we want swc?

bmuenzenmeyer · 2026-07-20T18:02:54Z

sorry if you felt pressured to close this. i sometimes crave a little more context and slowness. i saw some references to why this was needed, but it is still foggy to me if it can be solved within oxc or not

fix: oxc-parser to yuku-parser
