ComfyUI Extension: Quick Connections

Adds circuit board connections, quick connections to ComfyUI

• To install, go to ComfyUI manager -> look up "quick-connections"
• Demo

How to use...

• Don't block the output / input areas.
• Give it some room. If the connections have no room to move, it'll get confused.
• There is no insert dot in the middle of the connection. Drag the output to an empty spot, add a new node, and drag the output of the new node. Sorry.
• Can be disabled in options under "Quick connections", "Circuit Board lines"

Can be used with litegraph too. See example folder(examples won't work in windows because it doesn't support symlinks, use WSL).

To run examples...

npm install
python -m http.server
# visit in browser: http://localhost:8000/example/quick_conn.html
