# ComfyUI-AsyncPause **A node pack for pausing execution asynchronously and notifying the user**

## Nodes All the nodes are installed under the **`utils/`** category. ### `Pause` The **`Pause`** node allows you to pause execution and resume it when desired by clicking the **`continue`** button. The node runs asynchronously, so when a **`Pause`** node is reached and begins waiting for user interaction, other nodes that don’t depend on it can continue executing.

The default version includes a blinking **`continue`** button. The blinking functionality can be turned on or off, and both the blinking interval and color can be customized through the settings. Additionally, the node offers the following enhancements, all configurable via the settings: - **`cancel`** button: add a button to the node to interrupt the current run. - **`cancel and run`** button: add a button to the node to interrupt the current run and queue a new one. - **`force_pause`** toggle: when enabled, forces the node to execute even if the input has not changed. **Example workflows:** - Single pause node: [pause_single.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/pause/pause_single.json) - Chained pause nodes: [pause_chained.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/pause/pause_chained.json) - Parallel pause nodes: [pause_parallel.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/pause/pause_parallel.json) - Chained + parallel pause nodes: [pause_chained_parallel.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/pause/pause_chained_parallel.json) --- ### `Notify Audio` Triggers an audio notification when executed. Available as both an output node and a passthrough node.

Output node

Passthrough node

A preset collection of 12 notification sounds is included. **To add a custom sound:** 1. Copy your sound file into the `web/audio` folder. 2. Update the `sounds` object in `web/js/sounds.js` with the appropriate values. 3. Restart ComfyUI to apply the changes. Your custom sound will now appear in the dropdown list of available sounds. **Example workflows:** - As an output node: [audio_output.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/notify/audio_output.json) - As a passthrough node: [audio_passthrough.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/notify/audio_passthrough.json) --- ### `Notify Toast` Triggers a [toast notification](https://docs.comfy.org/custom-nodes/js/javascript_toast) when executed. Available as both an output node and a passthrough node.

**Example workflows:** - As an output node: [toast_output.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/notify/toast_output.json) - As a passthrough node: [toast_passthrough.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/notify/toast_passthrough.json) --- An example of a workflow combining the **`Pause`** node with notification nodes: [notify_and_pause.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/pause_and_notify.json) ## Subgraphs A common pattern is to create a subgraph containing a notification node **before** and/or **after** a **`Pause`** node to get notified when **reaching** and/or **leaving** a checkpoint. Example workflow using subgraphs: [pause_subgraphs.json](https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/workflows/pause_subgraphs.json) ## Related Custom Nodes - [ComfyUI-pause](https://github.com/wywywywy/ComfyUI-pause) includes a pause node, but it is not asynchronous and does not work properly with subgraphs. ## To-Do - ~~Make the **`Pause`** node blink while waiting for user interaction.~~ (done) - ~~Add a **`cancel and run`** button.~~ (done) - Support multiple dynamically added input and output connections. ## Support If you like this node pack, consider supporting my work with a coffee or a Bitcoin tip:
