App::JSONDiff - Shows the differences in json files

Goal

To be able to quick see what's different between similar json files.

I had several k8s environments and i wanted to compare the configmaps. A diff falls short since it compares line by line and in a json file the order of the name/value pairs doesn't matter much.

Usage

with file1.json as:

{
  "name": "John Smith",
  "age": 30,
  "email": "john.smith@example.com",
  "address": {
    "street": "123 Main St",
    "city": "Anytown",
    "state": "CA",
    "zip": "12345"
  },
  "phoneNumbers": [
    {
      "type": "home",
      "number": "555-1234"
    },
    {
      "type": "work",
      "number": "555-5678"
    }
  ],
  "isActive": true,
  "preferences": {
    "newsletter": true,
    "notifications": false
  }
}

with file2.json as:

{
  "name": "Jane Smith",
  "age": 28,
  "email": "jane.smith@example.com",
  "address": {
    "street": "456 Elm St",
    "city": "Anytown",
    "state": "CA",
    "zip": "12345"
  },
  "phoneNumbers": [
    {
      "type": "home",
      "number": "555-4321"
    },
    {
      "type": "work",
      "number": "555-8765"
    }
  ],
  "isActive": true,
  "preferences": {
    "newsletter": false,
    "notifications": true
  }
}

Invoke it:

$ jsondiff file1.json file2.json
