nsp-preprocessor-url

NSP URL preprocessor

An NSP input processor for URLs

use cases

For check for vulnerabilities in node.js dependencies in projects:

• without cloning large repos (or checking out specific branches or tags)

• with non-standard version file names

• with multiple package.json and other version files (e.g. if we have version files at https://github.com/me/myrepo/blob/master/frontend and https://github.com/me/myrepo/blob/master/old-frontend run this twice with both urls)

example usage

To install:

npm install -g nsp nsp-preprocessor-url
/usr/local/bin/nsp -> /usr/local/lib/node_modules/nsp/bin/nsp
+ nsp-preprocessor-url@0.2.1
+ nsp@3.2.1
updated 2 packages in 4.094s

To fetch and check standard version file names (package.json,npm-shrinkwrap.json and package-lock.json):

nsp check --preprocessor url --url https://raw.githubusercontent.com/mozilla-services/ip-reputation-js-client/2.1.1/ --verbose
