json-difference v1.16.1

JsonDifference

Computes the difference between two objects and returns an intuitive result. No matter how big your JSON is, the diff will be returned pretty fast.

The question you should ask is: Given my old structure what was changed, removed or added to the new structure?

Example

Usage

Method:

getDiff(oldStruct, newStruct)

Returns the structural difference between oldStruct and newStruct.

Simple usage:

import { getDiff } from 'json-difference'

const coffee = { color: { color1: 'black', color2: 'brown' }, special: true }
const oil = { color: { color1: 'red', color2: 'blue' }, special2: false, especial3: [{}] }

// Get JsonDiff delta
let diff = getDiff(coffee, oil)
let diff2 = getDiff(coffee, oil, true)

console.log(diff)
console.log(diff2)

Output:

{
  "added": [
    ["special2", false],
    ["especial3/0[]", {}]
  ],
  "removed": [["special", true]],
  "edited": [
    ["color/color1", "black", "red"],
    ["color/color2", "brown", "blue"]
  ]
}

{
  "added": [
    ["special2", false],
    ["especial3[0]", {}]
  ],
  "removed": [["special", true]],
  "edited": [
    ["color.color1", "black", "red"],
    ["color.color2", "brown", "blue"]
  ]
}
