Overview

Executes npm i module_name in a docker container and returns file system changes

Example Usage

var Docker = require('dockerode');
var docker = new Docker({socketPath: '/var/run/docker.sock'});
var getChanges = require('./index.js');

getChanges(docker, 'node', 'helmet', function (err, changes) {
    console.log(changes);
});

Returned changes object includes the following keys, which are each an array of files that were added, modified or deleted.

• modified
• added
• deleted

Options

getChanges requires the following options

• docker - connection to dockerode
• image - name of the image that you want to run npm i module against
• module_name - can be a module_name or module_name@version
• callback - function with the signature (err, changes)

scripts

To clean up after ourselves we have a scripts/cleanup.sh that will remove images that are lingering. May or may not be useful.
