A tiny library to find difference between two json objects
Install
npm install json-obj-diffUsage Example
import { jsonObjDiff } from "json-obj-diff";
const obj1 = {
a: 1,
b: [1],
c: {
d: 1,
e: "12312",
},
};
const obj2 = {
a: 10,
b: [1, 2, 3],
c: {
d: 10,
e: "1",
},
};
const diff1 = jsonObjDiff(obj1, obj2);
/*
diff1 = {
a: { _o: 1, _n: 10 },
b: {
'1': { _o: undefined, _n: 2 },
'2': { _o: undefined, _n: 3 },
_arr_len_o: 1,
_arr_len_n: 3,
_arr: true
},
c: {
d: { _o: 1, _n: 10 },
e: { _o: '12312', _n: '1' }
}
}

jsonDiff(
value1: any,
value2: any,
propNames: {
oldValue: string, // default '_o',
