comfyui-misc

ComfyUI custom nodes focused on small utility workflows.

Nodes

1) Any Switch (misc)

Selects one value from dynamic any_01, any_02, ... inputs.

• Input
  • select_index (INT):
    • -1: automatically choose the first non-empty any_* input
    • 0 or higher: force selection of any_{index+1}
  • any_01, any_02, ... (*): dynamic optional inputs
• Output
  • *: selected value
  • index (INT): selected input index (0-based)

How to use

1. Connect multiple candidates to any_* inputs.
2. Keep select_index=-1 for auto mode, or set a number for fixed mode.
3. Use index when downstream nodes need to know which branch was chosen.

2) Any Output Switch (misc)

Routes one input to one of dynamic outputs any_01, any_02, ...

• Input
  • input (*): value to route
  • select_index (INT):
    • -1: route to the first connected output slot
    • 0 or higher: force route to any_{index+1}
• Output
  • any_01, any_02, ... (*): dynamic outputs (only one is active)
  • index (INT): selected output index (0-based)

How to use

1. Connect input from an upstream node.
2. Connect each destination node to desired any_* outputs.
3. Choose auto mode (-1) or fixed mode (>=0) with select_index.

3) Combine Primitives (misc)

Combines primitive values into a single combined package.

• Supported primitive types
  • INT, FLOAT, STRING, BOOLEAN, COMBO
• Input
  • primitive_01, primitive_02, ... (PRIMITIVE) dynamic optional inputs
• Output
  • combined (PRIMITIVES)
  • length (INT): number of packed primitive values

How to use

1. Connect primitive-producing nodes to primitive_* inputs.
2. Send combined to Split Primitives (misc) or another compatible node.
3. Use length for loops/validation.

4) Split Primitives (misc)

Unpacks combined produced by Combine Primitives (misc).

• Input
  • combined (PRIMITIVES)
• Output
  • INT_01, FLOAT_02, ... (PRIMITIVE) dynamic outputs (typed names)
  • length (INT)

How to use

1. Connect combined from Combine Primitives (misc) (creating Split from the combined output search also syncs correctly).
2. Connect downstream primitive consumers to typed outputs such as INT_01.
3. Output slots auto-sync with upstream combine connections (even through relay nodes such as Any Switch (misc) and Reroute).
4. On workflow load / copy-paste restore, output links are preserved first and type-specific sync is applied after graph restoration settles.

Installation

1. Place this folder under ComfyUI/custom_nodes/comfyui-misc.
2. Restart ComfyUI.
3. Node category: misc.

Notes

• Dynamic slots are synchronized by JS extensions in js/.
• For workflow compatibility, keep ComfyUI and custom nodes up to date.
• See CHANGELOG.md for version history.

JavaScript unit tests (no ComfyUI required)

npm install
npm test

Tests live under test/js/ (one file per node, plus paste_restore.test.js for copy-paste link restore). Pure logic is in js/logic/.

Copy-paste and workflow load temporarily suppress dynamic slot removal so links can finish restoring before stabilize() trims unused sockets.
