	prop: 100,
	flag: true,
	a: true,
	b: true,
    c: true,
	type: 'pdf document',
}

Config loader

/**
* Loads `${PWD}/.config.js` by default
*/
const config = require('chen.js').config();

/**
* Loads `${PWD}/.cfg.js`
*/
const config = require('chen.js').config('.cfg.js');

/**
* Loads `${PWD}/.config.js`
* Loads `${PWD}/.config.dev.js` and overrides previous config
*/
const config = require('chen.js').config(['.config.js', '.config.dev.js']);

/**
* Assuming called with CLI args: --config=.config.dev.js
* Loads `${PWD}/.config.js`
* Loads `${PWD}/.config.dev.js` and overrides previous config
*/
const config = require('chen.js').config();

/**
* Assuming called with CLI args: --config=.config.dev.js --config=.config.dev2.js
* Loads `${PWD}/.config.js`
* Loads `${PWD}/.config.dev.js` and overrides previous config
* Loads `${PWD}/.config.dev2.js` and overrides previous config
*/
const config = require('chen.js').config();
