is-object-typeof-interface

A simple package which returns true when object is type of some specific interface or type.

This is my first package, hope it will be helpful. :heart:

Install with npm:

$ npm install is-object-typeof-interface

Usage

import isObjectTypeOfInterface from 'is-object-typeof-interface';

interface IObj1 {
  foo: string;
  bar: number;
}

interface IObj2 {
  baz: boolean;
  biz: string;
}

const obj1: any = { foo: 'str', bar: 5 };
const obj2: any = { baz: true, biz: 'str' };

const result1 = isObjectTypeOfInterface<IObj1>(obj1, 'foo');

Motivation

Receving an object from Redux store had two different types as the same component was rendering different datas, and I needed check what interface my object has to get correct property. After googling I found [this](https://stackoverflow.com/questions/14425568/interface-type-check-with-typescript) question and published this package, which will be extended in future.
