@kevit/mask

Description

This is a small utility which can help you mask the sensitive information from logs or databases or practically from anywhere.

It exposes a simple function which accepts JSON or string type data and it replaces sensitive data with masked data.

This can be used inside various hooks such as Mongoose hooks or express middlewares, in frontend before rendering data or before sending data back to backend etc.

Usage

Example with JSON data:

const data = {
    "name": "John Doe",
    "email": "[email protected]",
    "mobile": "9833316908",
    "aadhar": "123456789012",
    "dob": "01/01/1990",
    "pancard": "ABBPG6789L",
    "passportNumber": "A2190457",
    "pincode": "360001",
}

const result = getUpdateLogData(data);
console.log(result)

/* Output
* {
*  name: 'John Doe',
*  email: '[email protected]',
*  mobile: '9833XXXX08',
*  aadhar: 'XXXXXXXX9012',
*  dob: 'XX/XX/XXXX',
*  pancard: 'AXXXXXXXXL',
*  passportNumber: 'A2XXX57',
*  pincode: '3XXX1'
* }
*/

Example with String Data:

import { getUpdateLogData } from '@kevit/mask';
const data = ` This is a multi line string containing following values:
    name: John Doe  
    email: [email protected]
    mobile: 9833316908
    aadhar: 123456789012
    dob: 01/01/1990
    pancard: ABBPG6789L
    passportNumber: A2190457
    pincode: 360001
`

const result = getUpdateLogData(data);
console.log(result)

/**
