```PACKAGES
Published packages and verification scope.
This website's page bodies are Matra templates composed with page data, evaluated by @matra/core, generated across routes by @matra/site-generation, and rendered as HTML by @matra/html. The @matra/cli creates, builds, and previews starter projects. The examples below include provisional APIs; check each package's version and release notes.
Examples use Core 0.3.1-site.4, HTML 0.3.1-site.0, CLI 0.3.2-alpha.3, and site-generation 0.1.0-site.5; compatibility and APIs are provisional.
Verification target
Dependencies used by the website build
Review each package's role and a minimal usage example.
The left panel shows the complete Markdown source. matra.entry selects main.matra, and matra.values exposes the JavaScript expression as content. @matra/core evaluates the document, while @matra/site-generation builds a site from pages, shared layouts, and data. The CLI creates and builds starter projects. The code below shows each package in use.

Check role and publication status separately.
01
@matra/core
Provides grammar, evaluation, document AST, browser APIs, and the experimental literate API. This site uses the literate API to evaluate Matra documents.
const value = await runLiterate(await buildLiterate(source))Core source →02
@matra/cli
An experimental CLI for creating, building, and locally previewing starter projects.
npm install --global @matra/[email protected]
matra init hello
cd hello && matra devnpm package →03
@matra/site-generation
Generates a site from Matra templates, shared layouts, and page data. This package generates every route on this website. Its API and version are provisional.
await generateSite({ root, output: "dist", pages })Site generation source →04
@matra/html
Renders document AST to HTML with text/attribute escaping and base-path support. This website uses it through site-generation.
const html = toHTML(documentAST)HTML source →05
Other domain packages
Graphics, Math, and Compute Engine have separate verification scopes; publication and completeness are assessed separately.
Priorities and scope →Environment
The literate API targets Node.js 22/24.
The bundled compiler means Rust, a checkout, and an additional download are not required at runtime. The API is experimental; run only trusted input.
