@bpview/core

The engine behind Yarlis Blueprint: the Blueprint Diagram Model, the .ybp and .blueprint.yaml parsers, validation with line-level diagnostics, layout, themes, deterministic SVG, and Markdown block rendering. @bpview/core/node adds PNG (resvg, bundled Inter fonts) and isolated rendering with limits.

import { compile, renderSvg, transformMarkdown } from '@bpview/core'
import { renderIsolated, svgToPng } from '@bpview/core/node'

const { diagram, diagnostics, ok } = compile('flowchart\na: A\nb: B\na -> b\n', { file: 'x.ybp' })
if (ok && diagram) {
  const svg = renderSvg(diagram, { theme: 'yarlis' })
  const png = svgToPng(svg)
}

The root entry has no Node dependencies and runs in browsers. JSON Schema of the model: @bpview/core/schema.json. Docs: syntax, model.
