symlink-dependencies

Synopsis

var symlinkDeps  = require('symlink-dependencies');
var cacheDir     = __dirname + '/npm-cache';
var moduleDir    = __dirname + '/node_modules';
var dependencies = {
  'a-neat-package': '1.2.5' // Must be an exact version
}

// callback is optional, this function also returns a promise.
symlinkDeps(cacheDir, moduleDir, dependencies, function (err) {
  // module dir has been created if necessary, and each dependency is linked
  // into place
})

Description

This acts sort of like npm link, except it makes links from an npm cache directory (with paths like ${name}/${version}/package).

The stream mapper will blow up quite loudly if you try to use it on your normal npm cache though because that might break npm itself.

Stream API

You can also create a stream mapper that operates on a stream of dependency objects (as created by create-dependency-stream):

var mapper = symlinkDependencies.streamMapper({cache: cacheDir})
createDependencyStream(...).pipe(mapper)
//=> stream of ready-to-use dependencies (as long as they are pure JS)
