Mask values from given JSON (objects / arrays). Useful in protecting confidential data, mask it before sending it to third party applications.

Installation

$ npm i mask-json-path

OR

$ yarn install mask-json-path

Usage

const maskJson = require('mask-json-path')('***') // values will be replaced with '***'
const pathsToBeMasked = ['block[].price'];
const mockData = {"block":[{"type":"article","id":"1","price":"$40"},{"type":"article","id":"2","price":"$50"}]}
const maskedData = maskJson(mockData, pathsToBeMasked);
// maskedData = {"block":[{"type":"article","id":"1","price":"***"},{"type":"article","id":"2","price":"***"}]}

Note that input json object gets modified in the process, cloning isn't done.
