A Node.js utility for looking up OS-specific environment settings with fallback commands.
osenv is a Node.js utility library that provides a consistent interface for accessing operating system environment settings across different platforms. It solves the problem of platform-specific environment variable differences by abstracting them behind a unified API and providing fallback mechanisms when environment variables are unavailable.
Node.js developers building cross-platform applications or tools that need to access system environment information consistently across Windows, macOS, and Linux systems.
Developers choose osenv because it eliminates platform-specific code for environment access, provides reliable fallbacks when environment variables are missing, and offers a simple, memoized API that's both efficient and consistent across all major operating systems.
Look up environment settings specific to different operating systems.

Provides a unified API for environment access across Windows, macOS, and Linux, eliminating the need for platform-specific code, as shown in methods like `osenv.path()` and `osenv.shell()`.
Automatically executes system commands like `hostname` or `whoami` when environment variables are missing, ensuring reliable data retrieval even in misconfigured systems.
Memoizes results after the first lookup, making subsequent calls immediate and improving performance for repeated access, as mentioned in the README's usage examples.
Handles key OS settings like home directories, paths, shells, and editors with built-in defaults, abstracting away platform differences transparently.
First-time calls may execute system commands for fallbacks, introducing latency that can impact startup times or high-frequency operations.
Memoization means environment changes during runtime are not reflected, potentially returning stale data unless the process is restarted.
Only supports specific environment aspects listed in the API; accessing arbitrary environment variables still requires direct use of `process.env` or custom code.
