Archify Diagram Viewer

View Archify diagrams inside VS Code. Open a diagram's JSON source and see the interactive diagram next to it, updated as you type. Open rendered Archify HTML files in a viewer tab instead of a browser.

This is an unofficial extension. It bundles the Archify renderer (MIT, © tt-a1i) and runs it on VS Code's own Node runtime, so nothing else needs to be installed.

Features

• Live preview: for *.architecture.json, *.workflow.json, *.sequence.json, *.dataflow.json and *.lifecycle.json files, or any JSON with a diagram_type. Use the preview button in the editor title, Cmd/Ctrl+K V (to the side) or Cmd/Ctrl+Shift+V. The preview keeps the focus and route you selected (#focus=…, #route=…) when it re-renders.
• HTML viewer: right-click a rendered .html file and choose Open in Archify Viewer, or use Reopen Editor With… → Archify Diagram Viewer. For Archify HTML already open as text, a button appears in the editor title. The viewer reloads when the file changes on disk.
• Problems: archify validate runs on the source and reports schema, layout and evidence problems at the matching JSON location.
• Schema help: completion and hover documentation come from Archify's own JSON schemas.
• Source links: in source-backed diagrams, clicking a source reference opens that file and line range in the editor. If the file is not in the workspace, the web link opens instead.
• Export: the diagram's own Export menu (PNG, SVG, share card, …) saves through a VS Code save dialog.
• Commands: Archify: Render to HTML File…, Archify: Open in Browser, Archify: Refresh Preview, Archify: Show Source.

Source evidence

A diagram that declares meta.repository and sources is verified against a local Git checkout whose origin and pinned commit match. The extension uses the Git top-level directory of the diagram file, or archify.repoRoot when set.

When verification fails, the default (archify.sourceEvidence: "fallback") still shows the diagram without source links, explains why in a notice, and reports the reason as a warning. Set it to "strict" to treat this as an error, as the Archify CLI does. Render to HTML File… always verifies strictly and asks before rendering without source links.

Settings

Setting	Default	Description
archify.theme	vscode	vscode follows the color theme; dark or light force one; diagram keeps the diagram's own choice.
archify.preview.liveUpdate	true	Re-render while typing; when off, re-render on save.
archify.preview.debounceMs	400	Delay before re-rendering after an edit.
archify.validation.enabled	true	Report validation results in Problems.
archify.quality	""	Force the standard or showcase quality profile.
archify.sourceEvidence	fallback	fallback or strict handling of unverifiable source evidence.
archify.repoRoot	""	Checkout used to verify source evidence.
archify.nodePath	""	Node.js 18+ executable to use instead of VS Code's runtime.

Security

Diagrams run in a webview with a strict content security policy. Only the page's own inline scripts run (via a per-render nonce), there is no network access for scripts or fetches, and links open through VS Code.

Development

npm install
npm run build             # bundle to dist/
npm test                  # unit tests + renderer tests (Node)
npm run test:integration  # runs the suite inside VS Code
npm run package           # build archify-vscode-ext-<version>.vsix

Press F5 to launch an Extension Development Host with the test fixtures.

Updating the bundled renderer

vendor/archify/ and schemas/ are generated from an Archify checkout:

node scripts/sync-archify.mjs /path/to/archify   # default: ../../ws-storm/archify
npm test

vendor/archify.json records the upstream version and commit.
