Chainify

Make functions of an instance chainable

How to use Chainify

const chainify = require('@cokencode/chainify');

// An example instance
const calculator = {
  addOne: number => number + 1
  multiplyByTwo: number => number * 2
  addOnePromise: number => Promise.resolve(number + 1)
};

const chainableCaluculator = chainify(calculator, 3);

chainableCalculator
  .addOne()
  .multiplyByTwo()
  .multiplyByTwo()
  .addOne()
  .unwrapChainify()
  .then(result => console.log(result));
