# eV

The eV (electronvolt) provides a simple DOM-like event system.

## Installation

``` shell

$ npm install electronvolt

```

## Example

``` javascript

var ev = require("electronvolt");

// create event nodes

var node = new ev.EventNode();

var parent = new ev.EventNode();

// compose event flow

node.parentNode = parent;

var listener = function (event) {

    switch (event.eventPhase) {

        case ev.EventPhase.AT_TARGET:

            console.log("at target");

            break;

        case ev.EventPhase.BUBBLING_PHASE:

            console.log("bubbling phase");

            break;

        case ev.EventPhase.CAPTURING_PHASE:

            console.log("capturing phase");

            break;

    }

};

// add event listeners

node.addEventListener("example", listener);

parent.addEventListener("example", listener);

parent.addEventListener("example", listener, true);

// dispatch event into the event flow

node.dispatchEvent(new ev.Event("example", true));

// -> capturing phase

// -> at target

// -> bubbling phase

```
