Replace sensitive data in JSON (logs)

redact-sensitive.js

import cloneDeepWith from 'lodash.clonedeepwith' // or import { cloneDeepWith } from 'lodash'

function redactSensitiveData(data, sensitiveKeys)  {
  return cloneDeepWith(data, value => {
    if (value && typeof value === 'object') {
      sensitiveKeys.forEach(key => {
        if (value[key]) {
          value[key] = '[redacted]'
        }
      })
    }
  })
}

// Example
// >> redactSensitiveData({ name: 'john', password: '12345' }, ['password'])
// >> { name: 'john', password: '[redacted]' }
