A Node.js library to retrieve and validate the MAC address of the current machine or specific network interfaces.
getmac is a Node.js library that retrieves the MAC address of the machine it's running on. It solves the problem of programmatically accessing hardware identifiers in Node.js applications, which is useful for network configuration, device fingerprinting, and software licensing. The library works across different operating systems and provides both a CLI and API for flexibility.
Node.js developers who need to access network interface information, such as those building system administration tools, network monitoring applications, or software that requires device identification.
Developers choose getmac for its simplicity, reliability, and cross-platform support. It abstracts away the complexities of fetching MAC addresses across different OSes into a single, easy-to-use package, saving time compared to implementing low-level system calls manually.

Works consistently across different operating systems in Node.js environments, as emphasized in its philosophy of ensuring cross-platform compatibility.
Provides a single function call to retrieve MAC addresses, with clear examples in the README for both default and interface-specific lookups.
Allows fetching MAC addresses for specific network interfaces like 'eth0', enhancing precision without manual filtering.
Includes an `isMAC` function to validate MAC address formats, useful for input sanitization and configuration checks.
Only handles MAC address retrieval and validation; for advanced filtering, the README explicitly recommends using `os.networkInterfaces()` instead, indicating its narrow scope.
Explicitly does not run in web browsers or client-side frameworks, restricting its use to server-side Node.js applications and limiting versatility.
MAC addresses can be changed, virtualized, or spoofed, making it unreliable for unique device identification in scenarios like cloud environments or security-sensitive applications.
