isemptyobj's Introduction

isEmptyObj

Checks the given object is empty recursively (if needed) and returns true for empty.

Why this?

This library checks the given variable or object for the null or empty. This will recursively goes into the object if needed and checks for the null / empty values. For example if an Object is having multiple levels and all those levels have just empty value, this will return true. Even at the least level, if it finds a value associated of with any type like Array or Object or String or even number this returns false.

Installation

npm i @gkarthiks/isemptyobj

Usage

var a = [];

var b = {};

var c = [{}];

var d = [{1:2}];

var e = { one: 1 };

var f = {
  source: {}, 
  type: 'typeValue', 
  pool: {}, 
  acquireConnectionTimeout: 30000, 
  system: [ {
            a: [1,2], 
            c: [5,6] 
            }, 
            2]
  };

var g = {
timeseries: {
  tillDate: ['val1', 'val2', 'val3', 'val4', 'val5']
  }
};

var h = {
  timeseries: {
    tillDate: [],
    }
};

var i = {
  a: [], 
  b:{ }
};

var j = {
  a: [], 
  b:{ 
    aa:[11],
    bb:{}
  }
};

var k = {
  system: [ {
            a: [1,2], 
            c: [5,6], 
            }, 
          2]
};

var l = {
      source: {}, 
      type: "", 
      pool: {},
      acquireConnectionTimeout: '', 
      system: [ {
        a: [], 
        c: []
        }, 
      ]
  };
