redactyl.js

Redact sensitive information from JSON for logging (Node.js)

Installation

npm install -S redactyl.js

Usage

Instantiate a new instance of Redactyl, specifying the properties you wish to redact

const Redactyl = require('redactyl.js');

let redactyl = new Redactyl({
  // Required
  'properties': [ 'apiKey', 'password', 'phone' ],

  // Optional
  'text': '[REDACTED]',
  'replacer': myCustomReplacerFunction
});

Optional - provide your own replacer function:

function myReplacer(key, value) {
    ...some custom replacer logic here
}

redactyl.setReplacer(myReplacer);

Then run your sensitive data through the redact function!

const data = {
  'apiKey': 'a1b2c3',
  'password': 'P@$$w0rd',
  'phone': 1234567890,
  'device': 'ms-7821'
};

const redacted = redactyl.redact(data);
/* Result:
{
    'apiKey': '[REDACTED]',
    'password': '[REDACTED]',
    'phone': '[REDACTED]',
    'device': 'ms-7821'
}
*/
