Different types of link connections and geometry awareness.

Troubleshooting

• Only the center dot appears
  Likely start/end were read as arrays. Ensure you’re on v1.0.0+; we read {x,y} points.
• No lines drawn
  Check DevTools Console for warnings from ExtraLinks; verify ComfyUI is ≥ 1.27.1.
• After toggling Enable nothing changes
  Try reloading the page; ensure there’s no other extension overriding link rendering.

If issues persist, please open an issue with:

• ComfyUI frontend commit/date
• Browser + OS
• A screenshot / brief recording
• Console logs (copy/paste)

Development

• Main code lives in extralinks/web/ExtraLinks.js
• Settings/registration live in extralinks/web/extralinks_register.js
• Python exposes WEB_DIRECTORY via extralinks/__init__.py

Typical flow:

# edit JS files
# reload ComfyUI browser tab
# watch console for "[Extra Links]" logs

Optional Runtime guard:

const ok = app?.canvas?.linkRenderer?.pathRenderer?.drawLinkPath;
if (!ok) {
  console.warn("[ExtraLinks] Requires ComfyUI frontend >= 1.27.1");
}
