If you have example workflow files associated with your custom nodes then ComfyUI can show these to the user in the template browser (Workflow/Browse Templates menu). Workflow templates are a great way to support people getting started with your nodes. All you have to do as a node developer is to create an example_workflows folder and place the json files there. Optionally you can place jpg files with the same name to be shown as the template thumbnail. Under the hood ComfyUI statically serves these files along with an endpoint (/api/workflow_templates) that returns the collection of workflow templates.
The following folder names are also accepted, but we still recommend using example_workflows
  • workflow
  • workflows
  • example
  • examples

Example

Under ComfyUI-MyCustomNodeModule/example_workflows/ directory:
  • My_example_workflow_1.json
  • My_example_workflow_1.jpg
  • My_example_workflow_2.json
In this example ComfyUI’s template browser shows a category called ComfyUI-MyCustomNodeModule with two items, one of which has a thumbnail.
