Page compilation
Reads frontmatter and template HTML from src/pages/index.lilastro, validates required fields, and emits the root HTML document.
Implemented POC
Static page layer
Lilastro
A small .lilastro page compiler that keeps Lilscript in charge of application behavior and hands web delivery to Lilpack.
Its exact job
Static shell in, Lilscript entry out
Application code
The frontmatter points to main.lil. Listings, prices, quantities, screens, and rendered fragments remain Lilscript.
Delivery
Lilpack compiles the module graph before Vite 8 handles the dev server, HMR, Rolldown build, and Oxc minification.
Control flow
No hidden framework runtime

Interop and reload
TypeScript is a host, not the app language
The POC imports a small TypeScript adapter through typed Lilscript extern declarations. It performs DOM mounting, delegated click handling, timers, and scrolling. Business state never moves into a second implementation.
During development
A .lilastro edit regenerates the page. A .lil edit is recompiled through Lilpack and invalidates the Vite module graph at the Lilscript HMR boundary.
Controlled production result
The same accessible Parcel Market through two paths
The control uses plain Astro with no Solid integration. Both builds share the same CSS, behavior, focus restoration and announcements, modern ESM target, Vite 8.2.1, Rolldown/Oxc path, and disabled module-preload polyfill.
| JavaScript build | Brotli-11 · primary | gzip-9 | Raw |
|---|---|---|---|
| Lilastro + Lilpack | 2,665 B | 3,132 B | 7,957 B |
| Astro | 2,672 B | 3,132 B | 8,801 B |
Lilastro is 7 B smaller Brotli, ties gzip, and is 844 B smaller raw. The compressed result is effectively equal; this POC does not establish framework-wide superiority. Open both builds as demos.
