npm install shredfile

All of the values listed in the example below represent the default values for their respective configuration item.
You can simply do this:
var shredfile = require'shredfile';
And, you'll be good to go.
BUT: If you want more control, you can specify all sorts of options.
var shredfile = require'shredfile'shred_path: '/usr/bin/shred' // Path to shred binary on your serverforce: false // If true, changes permissions of file to allow writing if necessaryiterations: 3 // How many time to overwrite the filebytes: null // If specified, it will shred to specified bytes and then stopremove: true // If true, removes (unlinks) file after shreddingzero: true // If true, adds final overwrite with zeros to hide shreddingdebug_mode: false // Whether or not to log info/debug/error msgs to the console;
Here is a non-default values example (to help you get an idea of what the proper-looking values should be):
var shredfile = require'shredfile'shred_path: '/usr/local/bin/shred' // Maybe yours is located hereforce: true // You do want to change permissions to force writingiterations: 25 // You're paranoid. Writing over the file 25 times.bytes: '70M' // You're shredding the first 70 MB of the file onlyremove: false // You want to shred the file but keep it there.zero: false // You don't care about hiding the fact that you shredde the file.debug_mode: true // You want to know everything that happened.;
This method allows you to shred a one or many files.
