camelHumps

Allow accessing object with snake_case property names using camelCase property names

Why do I need it?

One example is whenever you'd like to seamlessly destructure or access an API request or response that are described in snake_case, by using camelCase for having a consistent code

Why choosing camelHumps over other similar packages?

Basically camelHumps utilizes NodeJS Proxy class and doesn't deep-clone the original object as other similar packages do.

Which results in

✅ No overhead of deep-cloning objects

✅ Minimal effect on memory footprint

✅ Applied only to fields that have being accessed

✅ Supports both snake_case and kebab-case

✅ Can mutate the original object 😱

Install

npm i camel-humps

API

camelHumps(obj, options)

options:

• kebab (false) - given object properties are in kebeb-case

Usage

const camelHumps = require('camelHumps');

const snakeObj = camelHumps(obj); // for snake_case
const kebabObj = camelHumps(obj, {kebeb: true}); // for kebab-case

Examples

const body = fetchData('/313');
console.info(body);
// result: { 
//     customer_details: { first_name: 'Jon', last_name: 'Stark' },
//     birth_place: 'Tower of Joy' }

const camelBody = camelHumps(body);
const { characterDetails } = camelBody;
console.info(characterDetails);
// result: { first_name: 'Jon', last_name: 'Stark' }

const { firstName, lastName } = characterDetails;
console.info({ firstName, lastName });
// result: { first_name: 'Jon', last_name: 'Stark' }

camelBody.characterDetails.firstName = 'Arya';
camelBody.birthPlace = 'Winterfel';
console.info(camelBody);
// result: {
//   characterDetails: { first_name: 'Arya', last_name: 'Stark' },
//   birthPlace: 'Winterfel' }
