What is npm-which?

The npm-which package is a utility that helps you locate the path of an executable that would be run by the shell if the given command was invoked. It is particularly useful for finding the location of executables in the context of npm scripts or node modules.

What are npm-which's main functionalities?

Locate Executable

This feature allows you to locate the path of an executable. In this example, it finds the path of the 'node' executable.

const which = require('npm-which')(__dirname);
which('node', function (err, path) {
  if (err) throw err;
  console.log(path);
});

Custom Path

This feature allows you to specify a custom path to search for the executable. In this example, it searches for the 'npm' executable in the '/custom/path' directory.

const which = require('npm-which')('/custom/path');
which('npm', function (err, path) {
  if (err) throw err;
  console.log(path);
});

Synchronous API

This feature provides a synchronous API to locate the executable. In this example, it synchronously finds the path of the 'node' executable.

const which = require('npm-which')(__dirname);
try {
  const path = which.sync('node');
  console.log(path);
} catch (err) {
  console.error(err);
}
