unix-permissions

Supports symbolic, octal, stat, and object representations, enabling seamless conversion between all common Unix permission notations as demonstrated in the examples and API.

Provides high-level methods for setting, testing, inverting, and comparing permissions, eliminating error-prone bitwise logic detailed in the README's operations section.

Automatically validates permission syntax and normalizes to canonical forms, such as condensing 'u+r,u+w' to 'u+rw', ensuring consistency without manual parsing.

Runs in Node.js ≥18.18.0 and modern browsers as an ES module, making it versatile for both server-side and client-side use, as highlighted in the install notes.
