Seven production pipeline utility nodes for ComfyUI: - PD Project Context: top-level metadata/token source - PD Shot Token: lightweight template string resolver - PD Output Namer: structured output filename builder - PD Network Output: image writer with UNC path support - PD Switch: multi-channel wildcard input router (up to 8×8) - PD Wedge: iteration node with optional auto-queue injection - PD Rasterizer: dry-run wedge cartesian product previewer Core infrastructure: - core/compat.py: legacy + Nodes 2.0 (V3) API compatibility shim - core/tokens.py: standalone token resolution engine - core/utils.py: path normalization and directory helpers - web/pipedream_rasterizer.js: minimal JS for rasterizer preview https://claude.ai/code/session_015UV4rjSvFatMiNtKhd1sT3
ComfyUI-Pipedream
Production pipeline utility nodes for ComfyUI — output naming, network paths, shot tokens, wedge iteration, and multi-input switching.
Pipedream is not a visual effects node pack. It is plumbing.
Installation
Clone into your ComfyUI custom_nodes directory:
cd ComfyUI/custom_nodes
git clone https://github.com/theonlyaaron/comfyui-pipedream.git
No additional dependencies are required.
Nodes
All nodes appear under the Pipedream category in the ComfyUI node menu.
| Node | Description |
|---|---|
| PD Project Context | Top-level metadata node (project, sequence, shot, version, artist). Acts as the root token source for a workflow. |
| PD Shot Token | Lightweight token resolver — takes a template string and inline widget values, outputs a resolved string. |
| PD Output Namer | Builds a structured output filename from a token template. Feeds into Save Image or PD Network Output. |
| PD Network Output | Writes images to a local or UNC network path with directory creation and overwrite control. |
| PD Switch | Routes one of N inputs to output per channel. Supports any type (wildcard), up to 8 channels with 8 inputs each. |
| PD Wedge | Iteration node — holds a list of values and emits one per execution. Optional auto-queue for batch iteration. |
| PD Rasterizer | Dry-run inspector — connects to wedges and previews the full cartesian product iteration table. |
Token Reference
Tokens are {name} placeholders resolved by PD Output Namer and PD Shot Token:
| Token | Source |
|---|---|
{project} |
Project Context or widget |
{sequence} |
Project Context or widget |
{shot} |
Project Context or widget |
{version} |
Project Context or widget |
{date} |
Auto: YYYYMMDD |
{time} |
Auto: HHMMSS |
{frame} |
Padded frame placeholder (e.g. ####) |
{wedge_idx} |
Current wedge iteration index |
{wedge_<name>} |
Named wedge current value |
Compatibility
Pipedream supports both the legacy ComfyUI node API and the Nodes 2.0 (V3) API. The compatibility layer detects which API is available at import time and registers nodes accordingly. No configuration needed.
