getInstalledPath

Get installed path of globally or locally name package. By default it checks if name exists as directory in global-modules directory of the system. Pass opts.local to get path of name package from local directory or from opts.cwd. Returns rejected promise if module not found in global/local node_modules folder or if it exist but is not a directory.

Params

name {string}: package name
opts {Object}: pass opts.local to check locally
returns {Promise}: rejected promise if name not a string or is empty string

Example

const { getInstalledPath } = require('get-installed-path')

getInstalledPath('npm').then((path) => {
  console.log(path)
  // => '/home/charlike/.nvm/path/to/lib/node_modules/npm'
})

getInstalledPath('foo-bar-barwerwlekrjw').catch((err) => {
  console.log(err.message)
  // => 'module not found "foo-bar-barwerwlekrjw" in path ...'
})

getInstalledPath('npm', {
  local: true
}).catch((err) => {
  console.log(err.message)
  // => 'module not found "foo-bar-barwerwlekrjw" in path ...'
})

getInstalledPath('global-modules', {
  local: true
}).then((path) => {
  console.log(path)
  // => '~/code/get-installed-path/node_modules/global-modules'
})

// If you are using it for some sub-directory
// pass `opts.cwd` to be where the `node_modules`
// folder is.
process.chidr('foo-bar-baz')
getInstalledPath('global-modules', {
  local: true,
  cwd: '../'
}).then((path) => {
  console.log(path)
  // => '~/code/get-installed-path/node_modules/global-modules'
})

// When searching for the path of a package that is required
// by several other packages, its path may not be in the
// closest node_modules. In this case, to search recursively,
// you can use the following:
getInstalledPath('npm', {
 paths: process.mainModule.paths
}).then((path) => {
 // ...
})
// `process.mainModule` refers to the location of the current
// entry script.

Params

name {string}: package name
opts {Object}: pass opts.local to check locally

Example

const { getInstalledPathSync } = require('get-installed-path')

const npmPath = getInstalledPathSync('npm')
console.log(npmPath)
// => '/home/charlike/.nvm/path/to/lib/node_modules/npm'

const gmPath = getInstalledPathSync('global-modules', { local: true })
console.log(gmPath)
// => '~/code/get-installed-path/node_modules/global-modules'
