react-notification

react-notification

Overview

This is a component designed to provide "snackbar" notification messages and notification stacks (similar to how notifications stack on OS X). I would suggest reading the usage guidelines for snackbars.

Getting Started

Install the component via npm: npm install react-notification.

If you are using the React 0.13.x or lower, you can install the previously compatible version of this component with npm i react-notification@2.3.0 -S. The current version only works with React 0.14.x.

Please read the contributing guide if you are interested in contributing. If you are coming from version 1.0.0, there is an upgrade guide to help you make the switch. If you have questions, please feel free to create an issue on GitHub.

Usage

Single notification:

import { Notification } from 'react-notification';

<Notification
  isActive={boolean}
  message={string}
  action={string}
  onClick={myClickHander}
/>

Notification stack:

import { NotificationStack } from 'react-notification';
import { OrderedSet } from 'immutable';

state = {
  notifications: OrderedSet().add({
    message: 'Notification message'
    key: 'some UID'
  })
}

// Using immutable.js for the array of notifications
render() {
  return (
    <NotificationStack
      notifications={this.state.notifications.toArray()}
      onDismiss={notification => this.setState({
        notifications: this.state.notifications.delete(notification)
      })}
    />
  );
}

See the examples for more context on how to use a notification stack.

Props

For Notification component:

Name	Type	Description	Required	Default
isActive	boolean	If true, the notification is visible	true	false
message	string or React element	The message or component for the notification	true
action	string	The name of the action, e.g., "close" or "undo"
style	boolean	Setting this prop to false will disable all inline styles
barStyle	object	Custom snackbar styles
activeBarStyle	object	Custom snackbar styles when the bar is active
actionStyle	object	Custom action styles
className	string	Custom class to apply to the top-level component
activeClassName	string	Custom class to apply to the top-level component when active		'notification-bar-active'
dismissAfter	number	Timeout for onDismiss event		2000

The style prop useful if you are not using React inline styles and would like to use CSS instead. See styles for more.

For NotificationStack component:

Name	Type	Description	Required	Default
notifications	array	Array of notifications to render	true

Note notifications used in a stack can not have actions and require a unique key property. All other properties included in the regular notification component are supported.

Events

For Notification component:

Event	Description
onClick	Callback function to run when the action is clicked
onDismiss	Callback function to run when dismissAfter timer runs out

For NotificationStack component:

Event	Description	Arguments
onDismiss	Callback function to run when dismissAfter timer runs out for a notification	The object for the notification currently being dismissed

Styles

This component does use basic inline CSS to style the position and visibility of the notification. You have two options for adding additional styles:

1. Remove all inline styles and use only CSS.
2. Add additional inline styles via the style prop.

The DOM tree of the component for reference:

<div class="notification-bar">
  <div class="notification-bar-wrapper" onClick={this.props.onClick}>
    <span class="notification-bar-message">{this.props.message}</span>
    <span class="notification-bar-action">{this.props.action}</span>
  </div>
</div>

To use additional inline styles, return two objects. The bar object applies styles to the entire notification "snackbar" and the action object applies styles to the action message. Under the hood, this uses Object.assign to handle properly combining styles.

I would highly suggest using this method since the styles included in the component by default handle the visibility of the notification. If you remove these styles, the component won't actually show or hide itself.

getNotificationStyles() {
  let bar = {
    background: '#263238'
  };

  let active = {
    left: '3rem'
  };

  let action = {
    color: '#FFCCBC'
  };

  return { bar, active, action };
},

render() {
  return (
    <div>
      <Notification
        ref="notification"
        message={this.state.message}
        action={this.state.action}
        style={this.getNotificationStyles()}
      />
    </div>
  );
}
