Installation

Clone this repository into your ComfyUI custom_nodes directory:

cd ComfyUI/custom_nodes
git clone https://github.com/Tsubasa109/ComfyUI-TemplateReference.git

Restart ComfyUI after installation.

Storage Location

The extension automatically creates local storage folders under ComfyUI's user directory:

ComfyUI/user/template_reference/prompt_templates/
ComfyUI/user/template_reference/prompt_templates/images/
ComfyUI/user/template_reference/reference_templates/
ComfyUI/user/template_reference/reference_templates/image/

These folders contain user-created JSON libraries and copied reference images.

Notes

Reference images are not embedded into JSON files. The JSON stores image metadata and the extension copies uploaded images into its storage folders.
If a saved image cannot be found, the node keeps the workflow running and returns a small placeholder image while logging a warning.
Runtime storage folders are ignored by Git and should not be committed to the repository.

File Format

All JSON template files are saved as UTF-8 without BOM.
Non-ASCII characters (including Japanese) are stored as-is in the JSON, not as escape sequences.
When opening saved JSON files in an external editor, make sure the editor is set to UTF-8 encoding.
