Redact Object

 

A javascript object redactor. So I like to output any configurations when my app starts up. Problem is if you have any passwords or other info you don't want in the log you have to clear it out beforehand.

Usage

Pass in an object and an array of members you want to redact. It will recursively travel the object redacting any matching members.

``javascript
const redact = require('redact-object');

var obj = {
foo: 'bar',
fizz: {
foo: 'oof',
key: 'value'
},
buzz: [
// it can do arrays too
{ foo: 'bar' },
22
]
};

/**
* Results in:
* {
* foo: '[ REDACTED ]',
* fizz: {
* foo: '[ REDACTED ]',
* key: 'value'
* },
* buzz: [
* // it can do arrays too
* { foo: '[ REDACTED ]' },
* 22
* ]
* }
*/
console.dir(redact(obj, ['foo']));
`

Arguments

- {object} target The target object to scan for redactable items
- {string[]} keywords A list of members to redact
- {string|Function} replaceVal Optional custom replace value, or function that returns replace value. Default value is [ REDACTED ]
- {object} config Option object of config settings:
- partial: boolean, will do partial matching if true, Default _true_
- strict: boolean, will do strict comparison (case sensitive) if true, Default _true_
- ignoreUnknown: boolean, will do strict comparison (case sensitive) if true, Default _false_

$3

replaceVal can be a function. This function will get two arguments (value, key):

- value: The value of the object
- key: The matched key

Your function's return will replace the value on the new object

#### Example

`javascript
const obj = {
firstname: 'Han',
lastname: 'Solo',
};

const replacer = val => [ REDACTED (${val.length}) ];
const redacted = redact(obj, ['firstname', 'lastname'], replacer);

/**
* Results in:
* {
* firstname: '[ REDACTED (3) ]',
* lastname: '[ REDACTED (4) ]',
* };
*/
