Summary:
The documentation is heavily focused on Windows environments, specifically Azure App Service on Windows with iisnode. All configuration, troubleshooting, and examples are tailored for Windows, referencing Windows-specific tools (e.g., iisnode, web.config, named pipes, Win32 error codes, Kudu CMD/PowerShell, d:\ paths). There are no Linux equivalents or cross-platform instructions/examples, and Linux troubleshooting or deployment patterns are not mentioned.
Recommendations:
- Add a parallel section or a separate guide for Node.js on Azure App Service for Linux, covering best practices and troubleshooting steps relevant to Linux environments.
- Provide Linux-specific examples for common tasks (e.g., configuration, debugging, log file locations, process management), using Linux tools and conventions (e.g., bash, systemd, Linux file paths).
- Reference Linux equivalents for Windows-specific tools and patterns (e.g., use of pm2 or systemd instead of iisnode, nginx/apache instead of IIS, environment variables instead of web.config).
- When mentioning troubleshooting steps (e.g., checking logs, profiling, debugging), include instructions for both Windows and Linux platforms, or clearly indicate which steps are platform-specific.
- Avoid assuming the use of Windows paths, tools, or error codes; provide cross-platform alternatives or clarify when something is Windows-only.
- Link to official Azure documentation for Node.js on Linux App Service where appropriate.
