Get and set properties in deeply nested object structures.

Installation

$ npm i objobj

Usage

Set and get a value in a deeply neste object structure:

const objobj = require('objobj');

const obj = objobj.get('a.b.c', 'cheeze');
const val = objobj.get('a.b.c', obj);

console.log(obj); // { a: { b: { c: 'cheeze' } } }
console.log(val); // cheeze

API

ObjObj has the following methods:

.get(path, object)

Get a value from a deeply nested object structure.

const objobj = require('objobj');

const obj = {
    a: {
        b: {
            c: 'cheeze',
        }
    }
}

const val = objobj.get('a.b.c', obj);
console.log(val) // cheeze

This method take the following arguments:

• path - String - The path, in dot notation, of the property to get - Required
• object - Object - The object to query - Required

If the path does not match anything in the object the method will return undefined.

.set(path, value, object)

Set a value into a deeply nested object structure.

const objobj = require('objobj');

const obj = objobj.set('a.b.c', obj, { bar: 'foo' });

/*
obj is now:
{
    a: {
        b: {
            c: 'cheeze',
        }
    },
    bar: 'foo',
}
*/

This method take the following arguments:

• path - String - The path of the property, in dot notation, to set a value - Required
• value - * - The value to set. Required
• object - Object - A object to append the value too - Optional

When a path is defined and it does not pre exist in object, a deeply nested object structure will be created based on path.

If object contain parts of the structure of the path, this will be left untouched and the rest of the structure in path will be appended to the pre existing structure in object.

If a value already exist on the path, the value will be overwritten.

If object is not provided, a new object will be created.
