Prevent duplicate install

[deitch]

Is there a way to prevent napa from reinstalling packages every time it runs?

Let's assume my package.json looks like this:

"dependencies": {
    "express": "3.x"
},
"napa":{
  "angular":"http://some.com/path/to/angular.git"
}

• If I run npm install once, it will download and install express. If I run npm install a second time, it will recognize that express 3.x is installed and not reinstall it
• If I run napa once, it will download and install angular. If I tun napa a second time, it will download and install angular again. And again. And again.

Is there any way that we can have napa recognize that it has already installed this fileset and not reinstall it? Understandably, npm install has a versionizing system, which npm relies upon to determine what is installed and what is not, while napa has no central repo to hit and check published version numbers. Is there any alternate way of doing it here?

Awesome, thank you!
