Summary
The documentation provides code samples for multiple languages (NodeJS, Java, PHP, C#, PowerShell, Bash) when generating SAS tokens, which is positive for cross-platform parity. However, the PowerShell example appears before the Bash example, and the Bash example is provided last, which may indicate a subtle 'windows_first' ordering. The PowerShell example is also more detailed and uses Windows-specific .NET libraries, which may not be available or work the same way on Linux. There are no explicit Linux command-line (e.g., curl, openssl) examples outside of Bash, and no mention of Linux-specific tools or patterns. The documentation references Azure portal and ARM templates for configuration, which are cross-platform, but does not mention Azure CLI or other Linux-native tools for disabling SAS authentication. There is also a heavy focus on .NET/.NET samples in the 'Samples' section, with no direct links to Linux/JavaScript/Python samples.
Recommendations
- Reorder code samples so that Bash (or other cross-platform scripting languages) appear before PowerShell, or present them side-by-side to avoid implying a Windows-first approach.
- Provide explicit Linux command-line examples (e.g., using curl and openssl) for generating SAS tokens and authenticating, in addition to Bash functions.
- Include references to Azure CLI commands for configuration tasks (such as disabling SAS authentication), as Azure CLI is widely used on Linux.
- Add links to sample code repositories for non-.NET languages (e.g., Java, Python, Node.js) in the 'Samples' section to ensure parity.
- Where PowerShell is used, clarify if it is cross-platform (PowerShell Core) or Windows-only, and provide equivalent Bash or shell commands for Linux users.
- Mention Linux tools or patterns where appropriate, such as using jq, curl, or openssl, and ensure that all steps can be performed on both Windows and Linux.
