Below is a very basic package.json file for a small node.js application I whipped up. It can be used as a boilerplate for new applications.

    "name": "json-lint-express",
    "preferGlobal": true,
    "version": "0.0.1",
    "author": "Cody Bonney <me@codybonney.com>",
    "description": "a simple web server that lints json strings",
    "license": "MIT",
    "engines": {
        "node": ">=0.10"
    },
    "scripts": {
        "start": "node ./app.js"
    },
    "dependencies": {
        "express": "~3.4.7",
        "json-lint": "~0.1.0"
    }
}
