Accepted Answer

Download lib folder from the (including all the files inside it).

Put all those files next to your node application in the same folder.

On the top of your application file where you have included other modules like HTTP etc. ..append this >

var multipart = require("./multipart")

You can download the full repo (not just the lib folder) into your application under a folder with the name node_modules.

Once you do that, your require will just be:

var multipart = require('multipart');

This is due to the way node resolves module dependencies. It will always look for a node_modules directory at the root of your app (and a few other places as well).

It's important you download the full repo and not just the lib folder if you plan to use it this way since the package.json file is used to find the main entry point.

 { "name" : "multipart"
, "version" : "0.0.0"
, "description" : "A JavaScript library for parsing and writing multipart messages"
, "contributors" :
  [ "Isaac Z. Schlueter <>"
  , "John Wright <>"
, "repository" :
  { "type" : "git"
  , "url" : ""
, "main" : "lib/multipart"

The advantage of this is compatibility with using npm install locally in your dev machine.

You can also download the tar file form github. Hit the Download button and deploy that with your app. Once that is done in your server you can run

npm install <path-to-the-tar-file>

That will install multipart on the machine for you.
