When a node is declared as dev-only, it doesn't show in the default UI unless the dev mode is enabled in the settings. The intention is to allow nodes related to unit testing to be included in ComfyUI distributions without confusing the average user.
Comfy Typing
Type hinting for ComfyUI Node development
This module provides type hinting and concrete convenience types for node developers. If cloned to the custom_nodes directory of ComfyUI, types can be imported using:
from comfy.comfy_types import IO, ComfyNodeABC, CheckLazyMixin
class ExampleNode(ComfyNodeABC):
@classmethod
def INPUT_TYPES(s) -> InputTypeDict:
return {"required": {}}
Full example is in examples/example_nodes.py.
Types
A few primary types are documented below. More complete information is available via the docstrings on each type.
IO
A string enum of built-in and a few custom data types. Includes the following special types and their requisite plumbing:
ANY:"*"NUMBER:"FLOAT,INT"PRIMITIVE:"STRING,FLOAT,INT,BOOLEAN"
ComfyNodeABC
An abstract base class for nodes, offering type-hinting / autocomplete, and somewhat-alright docstrings.
Type hinting for INPUT_TYPES
INPUT_TYPES return dict
Options for individual inputs
