NotificationBuilder bark.register(name)

Registers a new notification

//this will add a sort of "puff" alert 
defaults({ ok: "OK" }). //set the default OK message 
modalClass("alert-modal"). //the background color for the alerts. Makes content unclickable. 
transitionIn({ scale: 0.75, opacity: 1}, { scale: 1, opacity: 1}). //scale from -> to on transition in 
transitionOut({ scale: 1, opacity: 1 }, { scale: 1.25, opacity: 0}). //puff out 

Somewhere in your html <head />:

<script type="text/ejs" data-templateName="alert">
    <div class="alert">
        <div><%-message %></div>
        <a href="#" class="alert-ok close" data-name="ok"><%-ok %></a>

Now run your new alert:

Bark.alert("hello world!", function(event) {
    if(event.ok) {
        //do stuff

//closes the window after 5 seconds if the user hasn't clicked the "OK" button 
Bark.alert({ closeAfterTime: 5000, message: "You have mail" }, function() {
