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

Include coffee-script in package.json with the specific version required in each project, typically like this:

"dependencies":{
  "coffee-script": ">= 1.2.0"

Then run npm install to install dependencies in each project. This will install the specified version of coffee-script which will be accessible locally to each project.
