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 [email protected] -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.
Note the component uses Object.assign
. If you are compiling with Babel, you should include the Babel Polyfill in your build to ensure the method works.
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';
constructor () {
super();
this.state = {
notifications: OrderedSet()
};
}
addNotification () {
const newCount = count + 1;
return this.setState({
notifications: this.state.notifications.add({
message: `Notification ipsum...`,
key: 'some UID',
action: 'Dismiss',
onClick: () => this.removeNotification('some UID'),
})
});
}
removeNotification (count) {
this.setState({
notifications: this.state.notifications.filter(n => n.key !== count)
})
}
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 | |
title | string | The title for the notification | ||
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 or false | 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 | |
barStyleFactory | func | create the style of the notification | false | fn |
activeBarStyleFactory | func | create the style of the active notification | false | fn |
Update v5.0.3
: Now notifications used in a stack can have all properties included in the regular notification component.
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:
- Remove all inline styles and use only CSS.
- 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.
barStyleFactory and activeBarStyleFactory NotificationStack props
These two function have the following signature:
(index: Number, style: Object|Void) => Object
Where index
is the index of the notification in the notifications array and
style
is the style property of the individual notification.
This function is used to dynamically set the style of each notification in the
stack. The default function adds the bottom
style property to correctly
position of the notification in a stack.
function defaultStyleFactory(index, style) {
return Object.assign(
{},
style,
{ bottom: `${2 + index * 4}rem` }
);
}
