merge-objects-values

Installation

yarn add merge-objects-values OR npm i --save merge-objects-values

Usage

const merge = require("merge-objects-values");

// Simple merge
const object1 = { foo: 2 };
const object2 = { foo: 4 };

merge(null, object1, object2); // { foo: 6 }

// It merge recursively, so you can make the sum of sub-objects
const object3 = { foo: { bar: 2 } };
const object4 = { foo: { bar: 4 } };
const object5 = { foo: { bar: 6 } };

merge(null, object3, object4, object5); // { foo: { bar: 12 } }

// You can disable deep merge
const object6 = { foo: { bar: 2 } };
const object7 = { foo: { bar: 4 } };

merge({ deep: false }, object6, object7); // { foo: { bar: 4 } }

// You can apply transformer on number
const object8 = { foo: 10, bar: 3 };
const object9 = { foo: 2, bar: 9 };

merge({ number: (a, b) => a * b }, object8, object9); // { foo: 20, bar: 27 }

// You can apply transformer on string
const object10 = { bar: "oui" };
const object11 = { bar: "non" };
merge({ string: (a, b) => `${a} - ${b}` }, object10, object11); // { bar: "oui - non" }

The first param is the config, and all the next params are objects you want to merge.

config :

• deep Boolean, default true
• string Function
• number Function
