$3

``
let pathToPackage = require("global-modules-path").getPath("packageName");
`

The method returns the path to globally installed package or null. The code constructs the path based on the result of npm config get prefix and checks if the package exists.

$3


Example:
`
let pathToPackage = require("global-modules-path").getPath("packageName", "executableName");
`
The method returns the path to globally installed package or null. The code constructs the path based on the result of npm config get prefix and checks if the package exists. In case the package cannot be found in this way, the executableName is used to determine if the package is globally installed.
- On Windows the package spawns where executableName command and parses the result.
- On macOS and Linux the package spawns ls -l executableName and which executableName` and parses the results.

>NOTE: In some cases the executable name is not the same as the package name.
