[node.js] Find unused npm packages in package.json

many of the answer here are how to find unused items.

I wanted to remove them automatically.

  1. Install this node project.

    $ npm install -g typescript tslint tslint-etc


  1. At the root dir, add a new file tslint-imports.json

    { "extends": [ "tslint-etc" ], "rules": { "no-unused-declaration": true } }


  1. Run this at your own risk, make a backup :)

    $ tslint --config tslint-imports.json --fix --project .
