npm-utils

Async NPM shell commands: install, test, etc.

Use

var npmUtils = require('npm-utils');
npmUtils.version()
  .then(function (semver) {
    console.log('NPM version %s', semver);
  });

API

path() // returns immediately path to npm command

install({
  name: string,
  version: string (optional),
  prefix: string (optional), // folder path prefix
  passThroughData: obj (optional),
  registry: string (optional) // registry url,
  flags: ['--save', '--verbose'] // list of command line flags to pass to NPM
})

returns a promise

Note: the name could be another folder or a tar archive; passed to npm install <name> unchanged, that can be any match. See npm help install

version() // returns a promise, resolved with NPM version string

test() // spawns npm test command
test('grunt test'); // spawns new command "grunt test"

The child test process will inherit output streams from the parent.

registryUrl(); // returns a promise
// same as `npm config get registry` - which only uses
// .npmrc in the CURRENT folder (if there is .npmrc file)

publish({ tag: '...'});
// the tag is optional

pack

Runs npm pack <folder name> command. Resolves with the name of the generated tarball file.

pack({ folder: 'path/to/folder' })

If folder is not provided, uses the current one
