Command-exists is a lightweight npm package designed to quickly determine if a command-line tool is available in the user's environment. Versions 1.1.0 and 1.2.0 share the same core functionality, providing a straightforward way to check for the existence of commands, crucial for scripts and applications reliant on external utilities. Both versions are licensed under the MIT license, encouraging free use and modification, and maintained by Matthew Conlen. They both rely on the same set of development dependencies like expect.js for assertions, jshint for code quality, and mocha for testing.
The primary difference lies in the version number and release date. Version 1.2.0 was released shortly after 1.1.0, suggesting that the update likely addresses minor bug fixes, performance improvements, or dependency updates rather than introducing any significant new features. From a developer's standpoint, this means upgrading from 1.1.0 to 1.2.0 should be a seamless process with minimal risk of breaking existing code. Choosing the latest version 1.2.0, is generally recommended to benefit from any refinements and ensure compatibility with the latest Node.js environments. The library provides a clear and simple method to enhance reliability in projects that depend on specific command-line tools being present.
