How to use executables from a package installed locally in node_modules?

Question

How do I use a local version of a module in node.js. For example, in my app, I installed coffee-script:

npm install coffee-script

Answer 1

Use npm-run.

From the readme:

npm-run

Find & run local executables from node_modules

Any executable available to an npm lifecycle script is available to npm-run.

Usage

$ npm install mocha # mocha installed in ./node_modules
$ npm-run mocha test/* # uses locally installed mocha executable 

Installation

$ npm install -g npm-run
