Open URLs via Operating System

The `openurl` package provides a simple Node.js module to programmatically open URLs, `mailto:` links, or local files using the operating system's default applications. For instance, `http` links will open in the default web browser, and `mailto` links in the default email client. The package's current and final stable version is `1.1.1`, which was last published over 10 years ago in January 2016. Consequently, `openurl` is no longer actively maintained and does not receive updates, bug fixes, or new features. While it may still function for basic use cases in CommonJS environments, it lacks modern features like native ECMAScript Modules (ESM) support and may have unaddressed platform-specific issues. Developers are strongly encouraged to use actively maintained alternatives like the `open` package (by Sindre Sorhus) for better cross-platform compatibility, ESM support, and ongoing reliability.
