Hot reloading for custom node developers
This is a very hacky way to get hot reloading of custom nodes, but has worked very well on all workflows tested.
- Watches files in
ComfyUI/custom_nodes/ - Automatically reloads new code for any repo changed
- Clears the Comfy execution cache so Comfy will rerun nodes in changed repo
- Automatically loads in new repos that you download without the need to restart ComfyUI
After git cloning the repo into your custom_nodes/ you only need to install watchdog.
python -m pip install watchdog
HotReloadHack automatically watches files in your custom_nodes/ directory and when one changes reloads the node repo it belongs to.
It does not use a file dependency graph (yet), so all nodes in the changed repo will run on the next Comfy execution.
HOTRELOAD_EXCLUDE
comma separated list of module names exclude from forcing a reload.
Note: ComfyUIManager and ComfyUI-HotReloadHack are automatically excluded.
set HOTRELOAD_EXCLUDE=Jovimetrix,ComfyUIManager
HOTRELOAD_OBSERVE_ONLY
comma separated list of module names to be the exclusive list of modules to scan.
HOTRELOAD_EXTENSIONS
comma separated list of extensions. The default is to reload on .py, .json or .yaml file changes only. If you want to have it scan all extensions, use *.
