Path-key is a handy JavaScript package that allows you to get the PATH environment variable key in a cross-platform manner. This can be particularly useful because the casing of the PATH variable can differ depending on the operating system. For example, it's usually PATH but on Windows, it can be any casing like Path.
The usage of path-key is straightforward. To utilize path-key in your JavaScript project, first, you must install it using npm, as follows:
$ npm install path-key
After installation, you can import and use path-key into your JavaScript file as follows:
import pathKey from 'path-key';
const key = pathKey();
//=> 'PATH'
const PATH = process.env[key];
//=> '/usr/local/bin:/usr/bin:/bin'
The pathKey() function returns the PATH key tailored to the platform your script is currently running on. You can also pass a custom environment variables object or specify a platform to get the PATH key for a specific platform.
Regarding the path-key documentation, it's primarily found in the README.md file in the project's GitHub repository https://github.com/sindresorhus/path-key. This readme document provides an overview of the package, installation instructions, usage examples, and relevant API reference. Thus, it serves as the main documentation for path-key package.
