node-windows
A library to run Node.js scripts as native Windows services with event logging and elevated command execution.
What is node-windows?
node-windows is a Node.js library that provides Windows-specific support for running Node.js scripts as native Windows services in production environments. It enables service management, event logging, and administrative command execution without requiring native C++ modules or Visual Studio dependencies. The tool focuses on deployment reliability, generating an executable that works with the system's installed Node.js version.
Node.js developers and system administrators deploying Node.js applications on Windows servers who need to run scripts as background services with monitoring and logging. It is specifically for production environments rather than development.
Developers choose node-windows because it avoids the complexity of native modules and Visual Studio installations by using pre-packaged binaries, simplifying deployment. Its unique smart restart logic prevents server overload by intelligently managing service crashes with configurable retry intervals and caps.
Overview
Windows support for Node.JS scripts (daemons, eventlog, UAC, etc).
Use Cases
Best For
- Deploying Node.js applications as Windows services with automatic restart and monitoring.
- Writing application logs to the Windows Event Viewer without native C++ modules.
- Executing commands with elevated administrative privileges on Windows systems.
- Managing service dependencies and environment variables for Node.js scripts on Windows.
- Running Node.js scripts under specific user accounts or with custom Node executable paths.
- Killing processes by PID and listing running tasks on Windows from within Node.js.
Not Ideal For
- Projects that need to run on multiple operating systems without maintaining separate service management code.
- Development workflows where frequent service restarts and debugging are common, as node-windows is designed for production stability over development agility.
- Environments where users lack administrative privileges, since service installation and management require elevated permissions.
Pros & Cons
Pros
Avoids the need for Visual Studio and node-gyp by using pre-packaged binaries, simplifying installation on Windows systems as highlighted in the README's 'NO NATIVE MODULES' section.
Features configurable restart logic with exponential backoff and caps like maxRetries to prevent server overload from crashing services, detailed in the 'Smarter Restarts' documentation.
Allows setting environment variables, user accounts, dependencies, and custom Node executable paths, providing flexibility for production deployments as shown in multiple code examples.
Enables writing to Windows Event Viewer without C++ modules, supporting multiple log levels including audit events, with examples for info, warn, and error logs.
Cons
Exclusively designed for Windows, forcing teams to use separate tools like node-mac or node-linux for cross-platform deployments, limiting portability.
As noted in the troubleshooting section, uninstallation can fail due to locked log files, requiring manual intervention or re-runs, adding maintenance overhead.
Custom event codes are restricted to 1000 or less due to underlying eventcreate utility constraints, which may hinder detailed logging for some applications.
