@archstep/compiler

Lexer, parser, semantic validation, and IR emitter for Step — the text DSL behind ArchStep.

npm install @archstep/compiler

import { compile } from "@archstep/compiler";

const result = compile(`
architecture {
  service User at (0, 0)
  service API at (200, 0)
}

scenario Checkout {
  User -> API: "place order"
}
`);

if (result.ok) {
  console.log(result.ir); // { architecture, scenarios }
} else {
  console.error(result.errors); // [{ message, line }]
}

Part of the ArchStep monorepo — see the main README for the full pipeline (@archstep/runtime for playback timelines, @archstep/player for the animated renderer) and the language docs.
