deep-object-assign

Generate a copy of an object while modifiyng a part of its attributes. Can be useful for instance in Redux reducers.

Installation

npm install --save deep-object-assign

Usage

Let's consider the following object:

const person = {
  lastname: 'Potter',
  firstname: 'Harry',
  address: {
    country: 'Scotland',
    position: {
      latitude: 2.35311,
      longitude: 50.3534,
    }
  }
}

Let's imagine that we want to create a copy of this object while modifying the latitude attribute.

Using deep-object-assig, the code will looks like:

const deepAssign = require('deep-object-assign');
const modifiedCopy = deepAssign(person, { address: { position: { latitude: 1234}}});

/*
  modifiedCopy is: {
      lastname: 'Potter',
      firstname: 'Harry',
      address: {
        country: 'Scotland',
        position: {
          latitude: 1234,
          longitude: 50.3534,
        },
      },
    }
