npm-package-integrity

basic prepublish test for an npm package's integrity. runs npm pack then attempts to require the resulting tarball.

how

npm install --save-dev npm-package-integrity, and in your package.json:

{
    "scripts": {
        "prepublish": "npm-package-integrity"
    }
}

why

there's an npm bug that's particularly painful in node 6 and causes missing files in your package in certain circumstances. i've been bitten by it a few times. the packages are broken enough that require just doesn't work, so that's a good prepublish test.
