D2 edge-Wasm provenance

  • Engine: D2 parser/compiler/SVG renderer v0.7.1
  • Artifact: d2-custom.wasm
  • SHA-256: e27e0144f30e26b9891e086b6370c24755426d64934d61f8334002b2b4a3c663
  • Build inputs: source/worker.go, source/main.go, source/go.mod, source/go.sum, and the Worker-safe overlays/jsrunner source overlay.
  • Build command: npm run build:d2 from renderers/edge.
  • Build toolchain: Go go1.26.6.
  • D2 dependency: peeled module oss.terrastruct.com/d2@v0.7.1 (module is deprecated upstream in favor of github.com/d2lang/d2; the lockfile remains authoritative for this artifact).
  • Corresponding upstream source: https://github.com/terrastruct/d2/tree/v0.7.1
  • Layout: D2's bundled Dagre renderer with its default top-to-bottom flow. ELK is not included.
  • JavaScript runtime: Dagre executes inside the pure-Go Goja runtime. The build stages the pinned D2 module in a temporary directory and replaces only its runtime-selection files; the upstream Wasm host-eval runner is excluded because Workers prohibit dynamic code generation.
  • Host shim: Go standard wasm_exec.js from the build Go toolchain.

The D2 source and renderer are MPL-2.0. The generated artifact remains subject to the upstream D2 license and notices. Recipients can obtain the covered upstream source from the exact link above; DiagramZip's Worker entry points, module lock, runtime overlay, and reproducible build command are retained under renderers/edge/toolchains/d2/.
