Delete (nested) keys from JSON object

Assumptions

• original object shall not be modified by default
• modified object is returned
• nested keys shall be deleted as well

Usage

• takes two parameters (object, and keys to delete)
• second parameter is a string (for single key), or array (for multiple keys)

Installation

npm install key-del

Usage

var deleteKey = require('key-del')
var objWithoutOneAttribute = deleteKey({one: 1, two: 2}, 'one')

Examples

var deleteKey = require('key-del')

var originalObject = {
	one: 1,
	two: 2,
	three: {
	  nestedOne: 3,
	  nestedTwo: 4
	}
}

var result = deleteKey(originalObject, ['one', 'nestedOne'])

console.log(result)
// {two: 2, three: {nestedTwo: 4}}

// Delete nested key by full path
var objectToDeleteKeyFrom = { one: 1, two: 2, nested: {two: 2, three: 3}}
var keyToDelete = 'nested.two'
var result = delKey(objectToDeleteKeyFrom, keyToDelete)
console.log(result)
// { one: 1, two: 2, nested: {three: 3}}

Options

To delete attribue from the original object, set copy parameter to false (its true by default)

deleteKey(originalObject, 'one', {copy: false})
console.log(originalObject)
// original object is modified
// { one: 1, two: 2, three: { nestedOne: 3, nestedTwo: 4 } }
