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({source: 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({source: 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({source: src, repeat: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({source: src, repeat: 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({source:src, repeat:2, ignores:["foo"], fieldCallbacks: {
  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
//     }
//   ]
// ]
