Musk-clone NPM

musk-clone

Generate a mock shadow clone with same data structure, as speed as Elon Musk.

Tesla CEO Elon Musk has 9 children, says he's doing his part to increase U.S. fertility

Why musk-clone?

When you want to make a new mock item with same data structure as an exist one, you must copy --> modify one by one --> paste , this progress costs a lot time. Now you can musk-clone to save your time!

Feature

According to the incoming data, quickly generate a data of the same data structure, which is used to quickly construct mock data in the development stage

source mainly supports the two most common types, object types and array types, and supports deep nesting
Converts only the basic types string, number, boolean, the rest return the original value with the new memory address
Support repeat, return multiple musk-clone objects in batches
Supports ignoring some keys of mock objects
Supports customizing the return content of the key

Install

npm install musk-clone --save-dev

yarn add -D musk-clone

Usage

Basic Usage

import muskClone from 'musk-clone'

const src = ["foo", 1, true]
const target = muskClone(src);
console.log(target); 
// ["foo-0v3DrX7hoOqIFaQeMDDaF", 71, true],

Frequently-used Case

import muskClone from 'musk-clone'

const src = [
  { foo: "str", bar: 1, val: true },
  { foo: "str1", bar: 2, val: false },
]
const target = muskClone(src);
console.log(target); 
// [
//   { foo: "str-jHGKjWz3kz0ome5-tl6MS", bar: 36, val: false },
//   { foo: "str1-LqOPbB5xXYKXV8hmBB_Q6", bar: 2, val: true }
// ]

Clone multiple

import muskClone from 'musk-clone'

const src = [
  { foo: "str", bar: 1, val: true },
  { foo: "str1", bar: 2, val: false },
]
const target = muskClone(src, 2);
console.log(target); 
// [
//   [
//     {
//       "foo": "str-GEoG0NphDqhwQZ44aH2LF",
//       "bar": 5,
//       "val": true
//     },
//     {
//       "foo": "str1-mxD-IMD6U9BocOp8ql_XY",
//       "bar": 7,
//       "val": true
//     }
//   ],
//   [
//     {
//       "foo": "str-ldPI7kVtHeUOMph1U4yi8",
//       "bar": 3,
//       "val": true
//     },
//     {
//       "foo": "str1-EbVeOGe1YRjudpKDjA-gR",
//       "bar": 7,
//       "val": false
//     }
//   ]
// ]

Ignore mock object key

import muskClone from 'musk-clone'

const src = [
  { foo: "str", bar: 1 },
  { foo: "str1", bar: 2 },
]
const target = muskClone(src, 2, ignores: ['foo']);
console.log(target); 
// [
//   [
//     {
//       "foo": "str",
//       "bar": 5,
//     },
//     {
//       "foo": "str1",
//       "bar": 7,
//     }
//   ],
//   [
//     {
//       "foo": "str",
//       "bar": 3,
//     },
//     {
//       "foo": "str1",
//       "bar": 7,
//     }
//   ]
// ]

Customize the return content of the key

const src = [
  { foo: "str", bar: 1, val: true },
  { foo: "str1", bar: 2, val: false },
];
const target = muskClone(src, 2, ["foo"], {
  bar: (item) => item + Math.random(),
});
// [
//   [
//     {
//       "foo": "str",
//       "bar": 1.6969435733626381,
//       "val": true
//     },
//     {
//       "foo": "str1",
//       "bar": 2.8654049353811537,
//       "val": false
//     }
//   ],
//   [
//     {
//       "foo": "str",
//       "bar": 1.840926677103744,
//       "val": true
//     },
//     {
//       "foo": "str1",
//       "bar": 2.9165549953686725,
//       "val": false
//     }
//   ]
// ]
