Markdown,
to mdast

This is not mdast-util-from-markdown. It is a LilScript md→mdast compiler. 660 official cases parse to a root. Official rows are the published package plus micromark, then Terser and esbuild.

Official rows are one esbuild bundle of mdast-util-from-markdown@2.0.3 plus the packages it needs at runtime, then Terser or esbuild. LilScript is not post-minified. The npm file is the Brotli-scored compile. Closed LilScript is the same source with extern_fields = false.

Measured in Node

Same work,
two runtimes.

Not Playwright — Node v22.21.1 on this machine, quiet median after warmup. Race 10× in the playground for a browser number. The 660-case corpus is checksummed before any size row is a claim.

The receipts

Raw, gzip,

Official mdast-util-from-markdown@2.0.3 bundled with its runtime graph, then Terser (mangle on/off) and esbuild minify. LilScript is not post-minified. Closed LilScript is Brotli with extern_fields = false.

Why this surface. Comparing against a single published file would hide official dependencies. The fair fight is the runtime graph you actually import, then the same minifiers the JS ecosystem ships. Closed LilScript is the other honest comparison: no JavaScript options object, so those property names mangle.
