API

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.

.sync

Get installed path of a name package synchronous.

Params

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

Example

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

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

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

Contributing

Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.
Please read the contributing guidelines for advice on opening issues, pull requests, and coding standards.
If you need some help and can spent some cash, feel free to contact me at CodeMentor.io too.

In short: If you want to contribute to that project, please follow these things

1. Please DO NOT edit README.md, CHANGELOG.md and .verb.md files. See "Building docs" section.
2. Ensure anything is okey by installing the dependencies and run the tests. See "Running tests" section.
3. Always use npm run commit to commit changes instead of git commit, because it is interactive and user-friendly. It uses commitizen behind the scenes, which follows Conventional Changelog idealogy.
4. Do NOT bump the version in package.json. For that we use npm run release, which is standard-version and follows Conventional Changelog idealogy.

Thanks a lot! :)

Building docs

Documentation and that readme is generated using verb-generate-readme, which is a verb generator, so you need to install both of them and then run verb command like that

$ npm install verbose/verb#dev verb-generate-readme --global && verb

Please don't edit the README directly. Any changes to the readme must be made in .verb.md.

Running tests

Clone repository and run the following in that cloned directory

$ npm install && npm test
