Summary
The documentation is heavily focused on Windows-specific tooling and patterns, particularly IIS and iisnode, which are not available or relevant on Linux-based Azure App Service environments. All configuration and troubleshooting examples reference Windows concepts (e.g., web.config, named pipes, Win32 error codes, DLLs, Windows file paths), and there are no Linux equivalents or alternative instructions for Node.js apps running on Linux App Service. This creates a strong Windows bias and leaves Linux users without guidance.
Recommendations
- Add equivalent sections for Node.js on Linux App Service, covering configuration, troubleshooting, and best practices (e.g., using PM2, systemd, or Kudu for process management).
- Provide Linux-specific examples for log locations, error diagnosis, and configuration files (e.g., referencing app settings, environment variables, or startup scripts instead of web.config).
- Mention that iisnode and related settings are only applicable to Windows-based App Service plans, and link to Linux documentation where appropriate.
- Include troubleshooting steps for common Linux scenarios (e.g., file permissions, process crashes, out-of-memory errors) and how to access logs on Linux.
- Ensure parity in recommendations for performance tuning, debugging, and monitoring on Linux (e.g., using Azure Monitor, Application Insights, or Linux-native tools).
