gain

Getting Started

Gain's a really simple library intended to scan a Node project and detect any dependencies in your package.json that are never used in your application code. It doesn't check your node_modules, and it only looks at .js files right now.

We've provided gain as an in-memory module right now, and as a shell script. We're thinking about maknig a grunt and gulp tools for it when we get around to it.

For now, start off pulling the package to your machine:

npm install -g gain

Then you can cd to the root of your favorite node app and run from the command line:

gain

Which will give you a list of all the packages you have declared in the local ./package.json file that are never required in any of your .js files. We're still working on a solution that will check extensionless files, so for now if you have bin scripts they'll not be checked as locations for require statements.

Alternatively, you can install it in your app

npm install -g gain

Then you can make use of it in a file of your creation:

var gain = require('gain');

gain('./', function(err, excess){ 
   console.log(excess);
});
