# JsonPath Blacklist

Simple function for masking JSON with a list of JsonPaths

## Usage

```JavaScript

var blacklist  = require('jsonpath-blacklist');

var inputJSON = { a: 'keep', b: { c: ['keep', 'remove', 'remove']}};

var outputJSON = blacklist(['b.c[1]', 'b.c[2]'], inputJSON);

console.log(outputJSON);

// { a: 'keep', b: { c: ['keep'] }}

// Note that inputJSON is also changed.

console.log(inputJSON);

// { a: 'keep', b: { c: ['keep'] }}

// Object

outputJSON = blacklist(['b.c'], inputJSON);

console.log(outputJSON);

// { a: 'keep', b: {}}

// Attribute

outputJSON = blacklist(['a'], inputJSON);

console.log(outputJSON);

// { b: {}}

```

To avoid modification to the input, we can use an options argument:

```JavaScript

var blacklist  = require('jsonpath-blacklist');

var options = { deepCopy: true }

var inputJSON = { a: 'keep', b: { c: ['keep', 'remove', 'remove']}};

var outputJSON = blacklist(['b.c[1]', 'b.c[2]'], inputJSON);

console.log(outputJSON);

// { a: 'keep', b: { c: ['keep'] }}

console.log(inputJSON);

// { a: 'keep', b: { c: ['keep', 'remove', 'remove']}}

```

You can also replace the masked jsonpath is a string:

```JavaScript

var blacklist  = require('jsonpath-blacklist');

var options = { replacement: '<_masked_>' }

var inputJSON = { a: 'keep', b: { c: ['keep', 'remove', 'remove']}};

var outputJSON = blacklist(['b.c[1]', 'b.c[2]'], inputJSON);

console.log(outputJSON);

// { a: 'keep', b: { c: ['keep', '<_masked_>', '<_masked_>'] }}

```
