notr

Motivation

There are a ton of complicated notification frameworks out there. What I need is:

• Simple (no need for different animations)
• Simple (no jQuery)
• Simple (no built in icons)
• Simple (reasonable defaults)

Compatibility

• IE9+, FF, Chrome, Safari, iOS5+, Android

Note that the transition effect may not work devices not supporting the transition CSS style.

Installing with NPM

npm install -S notr

Installing with Bower

bower install -S notr

Usage

Require it

notr = require('notr')

Simple message, shows for 4 seconds.

notr('Hello <b>World!</b>')

Complicated message, stays until clicked.

notr({
    html: 'Hello <b>World!</b>'
    stay: 0
})

Hide message manually.

el = notr({
    html: 'Hello <b>World!</b>'
    stay: 0
})
 
... # sometime later 
 
el.hide() # div is extended with hide function 

Callback on hide

notr('Hello <b>World!</b>', function() {
    console.log('it closed');
});

Change content of existing

notr({
    html: 'Hello <b>World!</b>'
    id: 'myhello'
})

... # sometime later

notr({
    html: 'Goodbye cruel world!'
    id: 'myhello'
})

API

notr(html, callback)

Short form, equivalent to el = notr({html:html, callback:callback})

notr(opts)

Show a notification with possible options. Returns the <div> element.

args	desc
html	Text .innerHTML of the notification <div>.
className	.className of <div> in addition to "notr". Default "alert alert-info"
stack	Stack to place the notification in. See notr.defineStack(). Default "def"
stay	Milliseconds to stay on screen. 0 to stay forever. Default 4000
id	Id to change content/settings of notification on subsequent calls. Default null
onclick	Click handler. Default null which hides the <div>
callback	Callback when notification is about to hide.

Returns <div> extended with a .hide() function.

notr.defineStack(name, parent, styles)

To define a stack on screen where notifications appear. The default (which can be changed) is:

notr.defineStack('def', 'body', {top:'65px', right:'15px'})

args	desc
name	Name of the stack. The default notification stack is "def"
parent	document.querySelector or element of where to .appendChild the stack.
styles	el.style styles to define for the stack.

Default CSS styles

The notr default styles can be altered by overriding the default .notr css rule.

However. Notr uses the margin-top and opacity css style to do the transition animation. It's probably a bad idea to alter this value.

.notr {
    margin-top: 0; // do not change margin-top
    opacity: 1.0;  // do not change opacity
    float: left;   // probably a bad idea to change
    clear: both;   // probably a bad idea to change
    transition: margin-top 0.2s, opacity 0.2s;
 
    min-width: 270px;
    min-height: 50px;
    margin-bottom: 3px;
    background: white;
    border: 1px solid #999;
    padding: 5px;
    box-shadow: 0 0 3px rgba(0,0,0,0.4);
    cursor: pointer;
}
.notrstack {
    position: fixed;
    min-width: 270px;
    min-height: 50px;
    z-index: 9000;
}

Events

Some DOM events that are dispatched on the returned <div>.

event	desc
notr:beforeshow	Before showing.
notr:show	When showing.
notr:beforehide	Before hiding. Just before opts.callback.
notr:hide	After hiding.

Example

el = notr('Hi there')
el.addEventListener('notr:show', function() {
    console.log('here we go');
});
