Get the PATH environment variable key cross-platform
It's usually PATH but on Windows it can be any casing like Path...
While process.env.PATH reads correctly on Windows regardless of casing, you need the exact key when:
- Passing environment to child processes
- Working with custom environment objects (where case-insensitivity doesn't apply)
- Using worker threads (where case-insensitivity doesn't work)
npm install path-keyimport pathKey from 'path-key';
const key = pathKey();
//=> 'PATH'
const PATH = process.env[key];
//=> '/usr/local/bin:/usr/bin:/bin'Type: object
Type: object
Default: process.env
Use a custom environment variables object.
Type: string
Default: process.platform
Get the PATH key for a specific platform.
