Installation

Make sure that you are in your React Native project directory and run:

$ npm install react-native-message-bar --save

Basic Usage

• 1. Import the react-native-message-bar package

var MessageBarAlert = require('react-native-message-bar').MessageBar;
var MessageBarManager = require('react-native-message-bar').MessageBarManager;

• 2. Add the MessageBarAlert to your render function Note: Add it at the very end of your render function, the alert will then be displayed over any component of the view

// Within your render function.
// Include the MessageBar once within your top View element
// Make sure you add the MessageBar at the very bottom of your master component, then it will be displayed over all other components
<MessageBarAlert ref="alert" />

• 3. Register and Release your Message Bar as the current main alert

componentDidMount() {
  // Register the alert located on this master page
  // This MessageBar will be accessible from the current (same) component, and from its child component
  // The MessageBar is then declared only once, in your main component.
  MessageBarManager.registerMessageBar(this.refs.alert);
}

componentWillUnmount() {
  // Remove the alert located on this master page from the manager
  MessageBarManager.unregisterMessageBar();
}

• 4. Display the Message Bar Alert on demand

// Call this method after registering your MessageBar as the current alert
// By calling this method the registered alert will be displayed
// This is useful to show the alert from your current page or a child component
MessageBarManager.showAlert({
  title: 'Your alert title goes here',
  message: 'Your alert message goes here',
  alertType: 'success',
  // See Properties section for full customization
  // Or check `index.ios.js` or `index.android.js` for a complete example
});

Please note, if you do not provide a alertType, the info one will be chosen for you.

The normal duration of the notification is 3 seconds (3000 ms), you can override it. After this time, the notification is going to be hidden

See a full Example in index.ios.js or index.android.js.

Hide the Message Bar Alert

// You can force the current alert to be hidden through the Manager
MessageBarManager.hideAlert();

Customize Alert Type

The Message Bar Alert comes with 4 pre-configured alert style and 1 undefined extra. These alert styles defined the background color of the alert and the line stroke color. The 4 pre-configured alert styles are:

• info defined blue colors
• success defined green colors
• warning defined orange colors
• error defined red colors

The extra alert type allows you to use another 5th type.

MessageBarManager.showAlert({
  ...

  alertType: 'info', // Alert Type: you can select one of 'success', 'error', 'warning', 'error', or 'custom' (use custom if you use a 5th stylesheet, all are customizable). Default is 'info'

  /* Customize the stylesheets and/or provide an additional one 'extra' */
  stylesheetInfo : {{ backgroundColor : '#007bff', strokeColor : '#006acd',
                      titleColor: '#ffffff', messageColor: '#ffffff' }}, // Default are blue colors with white title and message
  stylesheetSuccess : {{ backgroundColor : 'darkgreen', strokeColor : '#b40000',
                         titleColor: '#ffffff', messageColor: '#ffffff' }}, // Default are Green colors with white title and message
  stylesheetWarning : {{ backgroundColor : '#ff9c00', strokeColor : '#f29400',
                         titleColor: '#ffffff', messageColor: '#ffffff' }}, // Default are orange colors with white title and message
  stylesheetError : {{ backgroundColor : '#ff3232', strokeColor : '#FF0000',
                         titleColor: '#ffffff', messageColor: '#ffffff' }}, // Default are red colors with white title and message
  stylesheetExtra : {{ backgroundColor : 'black', strokeColor : 'gray',
                         titleColor: '#ffffff', messageColor: '#ffffff' }}, // Default are blue colors with white title and message, same as info

  ...
});

Customize Alert Content

You can customize the style of the Title, Message and Icon/Avatar.

MessageBarManager.showAlert({
  ...

  title: "John Doe", // Title of the alert
  message: "Hello, any suggestions?", // Message of the alert
  avatar: "<URL/require('<path>') of your icon/avatar>", // Avatar/Icon <URL> of the alert or enter require('LOCALPATH') for local image

  /* Number of Lines for Title and Message */
  titleNumberOfLines: 1,
  messageNumberOfLines: 0, // Unlimited number of lines

  /* Style for the text elements and the  */
  titleStyle: {{ color: 'white', fontSize: 18, fontWeight: 'bold' }},
  messageStyle: {{ color: 'white', fontSize: 16 }},
  avatarStyle: {{ height: 40, width: 40, borderRadius: 20 }},

  ...
});

Customize Message Bar Alert Layout

You can customize the inset (padding) and the offset of the alert.

MessageBarManager.showAlert({
  ...

  /* Offset of the View, useful if you have a navigation bar or if you want the alert be shown below another component instead of the top of the screen */
  viewTopOffset : 0, // Default is 0
  viewLeftOffset : 0, // Default is 0
  viewRightOffset : 0, // Default is 0

  /* Inset of the view, useful if you want to apply a padding at your alert content */
  viewTopInset : 15, // Default is 0
  viewLeftInset : 0, // Default is 0
  viewRightInset : 0, // Default is 0

  ...
});

Customize Position and Animation, Twitter Style!

You can choose the position (topor bottom) of the alert. You can choose the way the alert is shown (SlideFromTop, SlideFromBottom, SlideFromLeft or SlideFromRight).

MessageBarManager.showAlert({
  ...

  /* Position of the alert and Animation Type the alert is shown */
  position: 'bottom',
  animationType: 'SlideFromLeft',

  ...
});

Setting default values for an alert reference

Default values (for style etc.) can be set when MessageBarAlert is added to your render function e.g.:

<MessageBarAlert
  ref="alert"
  titleStyle={{
    fontSize: 36,
    fontWeight: 'bold'
  }}
  messageStyle={{
    fontSize: 28
  }}
  duration={6000}
  viewTopOffset={10}
  stylesheetSuccess={{
    backgroundColor: '#52d80f',
    strokeColor: '#43c90e',
    titleColor: '#ffffff',
    messageColor: '#ffffff'
  }}
/>

These values override the built-in default values and hold for all MessageBarManager.showAlert() calls on the same reference. All properties except title, message, avatar, and alertType can be set in render.
