This node allows the execution of Node.js application within ComfyUI by leveraging the ComfyUI-NODEJS, which starts alongside ComfyUI and facilitates the installation of Node.js. The integration enables Python subprocesses to execute Node.js scripts.

• Node.js Installer: An semi-automated installation process of nodejs for windows users only.
• Package Installer: Supports the installation and automatic updating of Node.js packages upon each startup.
• Multiple scripts Execution: Enables running multiple projects simultaneously.
• Graceful Shutdown: The service terminates when ComfyUI exits.

Note: For non-windows user please install NodeJS before running this node
