What is obj-case?

The obj-case npm package provides utilities for manipulating and accessing properties within JavaScript objects using dot notation. It simplifies the process of getting, setting, and deleting nested properties.

What are obj-case's main functionalities?

Get Property

This feature allows you to retrieve the value of a nested property within an object using a dot-notated string.

const objCase = require('obj-case');
const obj = { a: { b: { c: 42 } } };
const value = objCase.get(obj, 'a.b.c');
console.log(value); // 42

Set Property

This feature allows you to set the value of a nested property within an object using a dot-notated string.

const objCase = require('obj-case');
const obj = { a: { b: { } } };
objCase.set(obj, 'a.b.c', 42);
console.log(obj); // { a: { b: { c: 42 } } }

Delete Property

This feature allows you to delete a nested property within an object using a dot-notated string.

const objCase = require('obj-case');
const obj = { a: { b: { c: 42 } } };
objCase.del(obj, 'a.b.c');
console.log(obj); // { a: { b: { } } }

obj-case

Work with objects of different cased keys. Anything supported by nbubna/Case. Makes finding and editing objects between languages a little more forgiving while still not modifying the original JSON.

.find(obj, key)

Returns the value for the object with the given key

objCase.find(obj, 'my.superCool.CLIMBING SHOES');  // 'x'

.del(obj, key, val, [options])

Deletes a nested key

var obj = { 'a wild' : { mouse : { APPEARED : true }}};
objCase.del(obj, 'aWild.mouse.appeared');
console.log(obj); // { 'a wild' : { mouse : {} }}

.replace(obj, key, val, [options])

Replaces a nested key's value

var obj = { replacing : { keys : 'is the best' }};
objCase.replace(obj, 'replacing.keys', 'is just okay');
