deep-object-compare

A robust utility for deeply comparing objects and providing detailed difference information. Handles nested objects and arrays.

Installation

``bash
npm install nested-object-compare
`

Usage

$3

`javascript
const { deepCompare } = require('nested-object-compare');

const obj1 = { a: 1, b: { c: 2 } };
const obj2 = { a: 1, b: { c: 2 } };

const result = deepCompare(obj1, obj2);
console.log(result);
// Output: { equal: true }
`

$3

`javascript
const obj3 = { a: 1, b: { c: 2, d: [3, 4] } };
const obj4 = { a: 1, b: { c: 2, d: [3, 5] } };

const result2 = deepCompare(obj3, obj4);
console.log(result2);
/* Output:
{
equal: false,
differences: []
}
*/
`

$3

`javascript
const resultVerbose = deepCompare(obj3, obj4, { verbose: true });
console.log(resultVerbose);
/* Output:
{
equal: false,
differences: [
{ path: '["b"]["d"][1]', value1: 4, value2: 5, message: 'Values differ: 4 vs 5' }
]
}
*/
`

$3

`javascript
const resultVerbose = deepCompare(obj3, obj4, { verbose: true,pathFormat: "dot" });
console.log(resultVerbose);
/* Output:
{
equal: false,
differences: [
{ path: "b.d.1", value1: 4, value2: 5, message: 'Values differ: 4 vs 5' }
]
}
*/
`

$3

`javascript
const obj5 = { a: 1, b: { c: 2 } };
const obj6 = { a: 1, b: { c: '2' } }; // '2' is a string

const result3 = deepCompare(obj5, obj6); // Strict (default)
console.log(result3);
/* Output:
{
equal: false,
differences: []
}
*/

const result4 = deepCompare(obj5, obj6, { strict: false }); // Loose
console.log(result4);
/* Output:
{ equal: true,
// differences: []
}
*/
