React Notification System

A complete and totally customizable notification system for React applications.

Demo

• http://igorprado.github.io/react-notification-system

Installing

For now this component is only available as CommonJS module. Install via NPM running:

npm install react-notification-system

Using

For optimal appearance, this component must be rendered on a top level HTML element in your application to avoid position conflicts.

Here is a basic example. For a more advanced usage, please see the example code.

varReact=require('react');varNotificationSystem=require('react-notification-system');varMyComponent=React.createClass({_notificationSystem: null,_addNotification: function(event){event.preventDefault();this._notificationSystem.addNotification({message: 'Notification message',level: 'success'});},componentDidMount: function(){this._notificationSystem=this.refs.notificationSystem;},render: function(){return(<div><buttononClick={this._addNotification}>Add notification</button><NotificationSystemref="notificationSystem"/></div>);}});React.render(React.createElement(NotificationSystemExample),document.getElementById('app'));

Creating a notification

The notification object has the following properties:

Name	Type	Default	Description
title	string	null	Title of the notification
message	string	null	Message of the notification
level	string	null	Level of the notification. Available: success, error, warning and info
position	string	tr	Position of the notification. Available: tr (top right), tl (top left), tc (top center), br (bottom right), bl (bottom left), bc (bottom center)
autoDismiss	integer	5	Delay in seconds for the notification go away. Set this to 0 to not auto-dismiss the notification
dismissible	bool	true	Set if notification is dismissible by the user. See more
action	object	null	Add a button with label and callback function. See more
onRemove	function	null	A callback function that will be called when the notification is about to be removed. The first argument is the original notification e.g. function (notification) { console.log(notification.title + 'was removed'); }
uid	integer/string	null	Overrides the internal uid. Useful if you are managing your notifications id. Notifications with same uid won't be displayed.

Dismissible

If set to false, the user will not be able to dismiss the notification. For this reason, if set to false, the action becomes required as the only way to dismiss the notification.

Action

Add a button and a callback function to the notification. If this button is clicked, the callback function is called and the notification is dismissed.

notification={[...],action: {label: 'Button name',callback: function(){console.log('Notification button clicked!');}}}

Styles

This component was made to work as plug and play. For that, a handcrafted style was added to it and is used as inline CSS.

You can change this style by overriding the default inline styles or disable all inline styles and use your own styles.

Overriding

For this, use the style prop to pass an object with your styles. Your object must be something like this:

varstyle={NotificationItem: {// Override the notification itemDefaultStyle: {// Applied to every notification, regardless of the notification levelmargin: '10px 5px 2px 1px'},success: {// Applied only to the success notification itemcolor: 'red'}}}<NotificationSystemref="notificationSystem"style={style}/>

Refer to this file to see what can you override.

Disabling inline styles

To disable all inline styles, just pass false to the prop style.

<NotificationSystemref="notificationSystem"style={false}/>

Here is the notification HTML:

<divclass="notifications-wrapper"><divclass="notifications-{position}"><!-- '{position}' can be one of the positions available: ex: notifications-tr --><divclass="notification notification-{level} notification-{state} {notification-not-dismissible}"><!-- '{level}' can be: success | error | warning | info. '{state}' can be: visible | hidden. {notification-not-dismissible} is present if notification is not dismissible by user --><h4class="notification-title">Default title</h4><divclass="notification-message">Default message</div><spanclass="notification-dismiss">×</span><divclass="notification-action-wrapper"><buttonclass="notification-action-button">Action button</button></div></div></div></div>

Important

Using this method you have to take care of every style, since containers positions and the animations. To control animations, use the classes notification-visible and notification-hidden. If your CSS styles will not handle any animation (transition), you need to set the prop noAnimation to true when adding the Notification System component:

<NotificationSystemref="notificationSystem"noAnimation={true}/>
