sanitise v1.0.3

Sanitise

A simple utility function that sanitises specified object key values.

Why this exists

I was becoming quite sick of having to always think about sanitising sensitive data to logs so i wrote this little utility to take the headache out of it.

Key Concepts

Require in the module passing in an array of object(s) which detail the key and the replacement value to use (e.g. [{key: 'secretkey': replaceWith: 'xxxxx'}] ). This will return a function which takes the object you wish to sanitise, a new sanitised object is then returned.

Example

const sanitise = require('sanitise');

const PROPERTIES_TO_SANITISE = [
    { key: 'name', replaceWith: '========' },
    { key: 'postcode', replaceWith: '--------' },
    { key: 'age' } // default replacement of "******" will be used
];

const sanitiseData = sanitise(PROPERTIES_TO_SANITISE);

const TEST_DATA = {
    name: '[this will be replaced]',
    age: '[this will be replaced]',
    nationality: 'british',
    address: {
      street1: '47 somewhere',
      postcode: '[this will be replaced]'
    }
  };

let sanitisedObject = sanitiseData(TEST_DATA)
