How to Install

Node

$ npm install --save-dev debuk

in the code

import Debuk from 'debuk';
var Debuk = require('debuk');

Browser(UMD)

This can be directly included into client side without any dependencies via

<!--- latest version --->
<script src='https://unpkg.com/debuk/dist/debuk.js'>
<!--- minified version --->
<script src='https://unpkg.com/debuk/dist/debuk.min.js'>
 
<!--- a specific version --->
<script src='https://unpkg.com/debuk@1.0.0/dist/debuk.js'>
 
<script>
var Debuk = debuk.default;
</script>

you can also download source from the Releases

Browser

If you are using any dependency management system like webpack or browserify, you can use the Node import

Usage

Debuk is a wrapper to any function or class. You can simply wrap any function or class with Debuk and you can use it to check different runtime behaviours of that function and class.

const myFun = function MyFun(){
// implementation
}
 
// Wrap the method with Debuk
const myFun = Debuk(function MyFun(){
// implementation
});
 
class MyClass {}
 
// Wrap class with Debuk
const DebukClass = Debuk(MyClass);
const myClass = new DebukClass();

Simple example (Number of method calls)

var mySum = function mySum(a, b){
  return a + b;
};
 
var list = [1,2,3,4,5,6];
list
  .map(i => mySum(i, 5))
  .reduce((a,i)=> mySum(+ 2, mySum(i, 5)));

Can you guess the number of mySum calls in the the above code and the parameters each were called with? Change the code above to wrap mySum with Debuk as below and you can view them on your browser console alone with the time it took to execute each function.

var mySum = Debuk(function mySum(a, b){
  return a + b;
});
//Console output
mySum: 0.182ms
mySum params 1,5 => 6
mySum: 0.103ms
mySum params 2,5 => 7
mySum: 0.076ms
mySum params 3,5 => 8
mySum: 0.076ms

mySum: 0.074ms

mySum: 0.075ms
mySum params 70,16 => 86
mySum count: 16

Check JSBin

Console.count does the samething

Well in case you didnt know you can use console.count to do the samething. But what is more about Debuk is that it does the count per execution cycle not global. So it will show how many times the method was used for that execution cycle. In most of the cases you want to check what happens when on a particular state. (When the user clicks on this button how many times this method was called). Debuk is ideal for that.
