A complete and totally customizable component for notifications in React.

Initially built for Eterpret @ Scalable Path.



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

npm install react-notification-system


For React ^0.14.x or React ^15.x.x, use version 0.2.x:

npm install react-notification-system@0.2.x

For React 0.13.x, use version 0.1.x:

npm install react-notification-system@0.1.x


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.

var React = require('react');
var ReactDOM = require('react-dom');
var NotificationSystem = require('react-notification-system');

var MyComponent = React.createClass({
  _notificationSystem: null,

  _addNotification: function(event) {
      message: 'Notification message',
      level: 'success'

  componentDidMount: function() {
    this._notificationSystem = this.refs.notificationSystem;

  render: function() {
    return (
        <button onClick={this._addNotification}>Add notification</button>
        <NotificationSystem ref="notificationSystem" />




Add a notification object. This displays the notification based on the object you passed.

Returns the notification object to be used to programmatically dismiss a notification.


Remove a notification programmatically. You can pass an object returned by addNotification() or by onAdd() callback. If passing an object, you need to make sure it must contain the uid property. You can pass only the uid too: removeNotification(uid).


Removes ALL notifications programatically.

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 (callback is optional). See more
children element,string null Adds custom content, and overrides action (if defined) See more
onAdd function null A callback function that will be called when the notification is successfully added. The first argument is the original notification e.g. function (notification) { console.log(notification.title + 'was added'); }
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.


If set to false, the notification will not display the dismiss ('x') button and will only be dismissible programmatically or after autoDismiss timeout. See more


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

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


Add custom content / react elements

notification = {
  children: (
      <h2>Hello World</h2>


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.


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

var style = {
  NotificationItem: { // Override the notification item
    DefaultStyle: { // Applied to every notification, regardless of the notification level
      margin: '10px 5px 2px 1px'

    success: { // Applied only to the success notification item
      color: 'red'

<NotificationSystem ref="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.

<NotificationSystem ref="notificationSystem" style={false} />

Here is the notification HTML:

<div class="notifications-wrapper">
  <div class="notifications-{position}"> <!-- '{position}' can be one of the positions available: ex: notifications-tr -->
    <div class="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 -->
      <h4 class="notification-title">Default title</h4>
      <div class="notification-message">Default message</div>
      <span class="notification-dismiss">×</span>
      <div class="notification-action-wrapper">
        <button class="notification-action-button">Action button</button>


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:

<NotificationSystem ref="notificationSystem" noAnimation={true} />

  • Improve performance


Clone this repo by running:

git clone git@github.com:igorprado/react-notification-system.git

Enter the project folder and install the dependencies:

npm install

To start a development server and use the example app to load the component, type:

npm start

Open http://localhost:8000.

Run the tests:

npm test

You can find the coverage details under coverage/ folder.

After that, just edit the files under src/ and example/src/app.js. It uses React hot reload.

This component is under construction. I will add more guidelines to who wants to contribute.
