ArcMoon

ArcMoon is a template language. You write .arcm files, and ArcMoon builds them into web pages.

Beta. ArcMoon works, but things may change before 1.0.

What is ArcMoon?

A .arcm file holds a page's markup, styles and code. ArcMoon builds it into a web page.

Markup: blocks like [p]Hello[end] become HTML elements. Pages are built from components and layouts.
Code at build time: code in ${ }$ runs in Node.js while the page is built. It can read files, use npm packages and fill the page with data.
Code in the browser: code in runtime ${ }$ runs in the browser. Live values update the page when their data changes.
Styles: a component's [style] only styles that component.
Output: plain HTML, with only the CSS and JavaScript each page needs.

[import = Layout: "./Layout.arcm" !]

${ const name = "World"; }$

[Layout = title: "Home"]
  [h1]Hello, ${ name }$![end]
[end]

Install the arcm command:

npm install -g arcmoon

Check that it works:

arcm -v

arcmoon and its short name arcm are the same command.

To use ArcMoon from JavaScript, install it in your project instead:

npm install arcmoon

ArcMoon needs Node.js 20.10 or newer.
