how to properly use node modules with meteorhacks npm

Question

First time trying to use node module with meteor

installed:

meteor add meteorhacks:npm

then installed:

npm install multer

have a separate file in the server directory, called "loadMulter" with just this one line:

var multer = Meteor.npmRequire('multer');

now, running "meteor" and getting this error:

What is the proper way to put these things together?

Don't install the npm package as a local node_module using npm install.

You need to specify the packages you want in a special file named package.json created after you add meteorhacks:npm and launch Meteor.

{
  "multer": "0.1.8"
}

You cannot run npm install multer in Meteor app.

The correct way is:

meteor add meteorhacks:npm
Create file packages.json in top level directory with content:
```
{
  "multer": "0.1.8"
}
```
Run meteor, the NPM package(s) will be installed automatically
Include npm package using Meteor.npmRequire

Note: Be sure to delete node_modules folder created by previous npm install.
