# Tap

[![Build Status](https://travis-ci.org/maexsoftware/tap.svg?branch=master)](https://travis-ci.org/maexsoftware/tap)

A typescript implementation of Ruby's tap.

## Usage

If you want to get started right away then you can extend `TappableClass`. This

will give you a basic implementation of the tap method.

```ts

class BasicExampleClass extends TappableClass {

  public value:number = 0;

  

  public get ():number {

    return this.value;

  }

  

  public set (value:number):this {

    this.value = value;

    return this;

  }

}

const example = new BasicExampleClass();

example

  .set(10)

  .set(20)

  .tap(value => console.log(value)) // 20

  .set(30)

  .get(); // 30

```

If you want more control over the tap method implementation for your class then

you can simply implement `ITappableClass` with your own implementation.

```ts

class ExampleClass implements ITappableClass {

  tap (fn: (value: this) => void): this {

    const clone:this = Object.assign({ __proto__: Object.getPrototypeOf(this) }, this);

    const froze:this = Object.freeze(clone);

    fn.call(null, froze);

    return this;

  }

}

```
