Overview

This node triggers workflows based on events from Aria2, a download utility, via a WebSocket connection. It listens for specific download-related events such as download start, pause, stop, completion, and errors. This node is useful for automating actions in response to download status changes, for example, notifying users when a download completes or handling errors automatically.

Use Case Examples

1. Automatically send a notification when a download completes.
2. Pause other processes when a download is paused.
3. Log download errors for troubleshooting.

Properties

Output

JSON

• event - The type of Aria2 event that triggered the workflow (e.g., downloadStart, downloadComplete).
• data - The detailed parameters and data associated with the event from Aria2.

Dependencies

• Requires an Aria2 API WebSocket URL and secret token for authentication, provided via credentials.

Troubleshooting

• WebSocket connection errors may occur if the Aria2 WebSocket URL or secret token is incorrect or the Aria2 server is unreachable. Verify credentials and network connectivity.
• If no events are triggered, ensure the selected events match those emitted by the Aria2 server and that the WebSocket connection is successfully established.
• Errors parsing WebSocket messages may indicate unexpected message formats; check Aria2 server version and compatibility.
