Install

This project requires Node.js v6 and above. Use yarn v1 / npm v5 or above to install it.

$ yarn add get-installed-path

API

Review carefully the provided examples and the working tests.

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.

getInstalledPathSync

Get installed path of a name package synchronous.
Returns boolean when paths option is used and filepath is directory,
otherwise returns a full filepath OR throws error.

Params

• name {string}: package name
• opts {Object}: pass opts.local to check locally
• returns {string}: The full filepath or throw TypeError if name not a string or is empty string

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'
