## Installation
Make sure that you are in your React Native project directory and run:
```batch
$ npm install react-native-message-bar --save
```
## Basic Usage
- 1. Import the `react-native-message-bar` package
```javascript
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
```javascript
// 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
```
- 3. Register and Release your Message Bar as the current main alert
```javascript
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
```javascript
// 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
```javascript
// 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.
```javascript
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.
```javascript
MessageBarManager.showAlert({
...
title: "John Doe", // Title of the alert
message: "Hello, any suggestions?", // Message of the alert
avatar: "') of your icon/avatar>", // Avatar/Icon 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.
```javascript
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 (`top`or `bottom`) of the alert.
You can choose the way the alert is shown (`SlideFromTop`, `SlideFromBottom`, `SlideFromLeft` or `SlideFromRight`).
```javascript
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.:
```javascript
```
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.
## Properties
Prop | Type | Default | Description
--------------------- | -------- | -------------------- | -----------
title | String | | Title of the alert
message | String | | Message of the alert
avatar | String | | Avatar/Icon source/URL of the alert. Use for a remote image file (eg `avatar: 'http://mywebsite.com/myimage.jpg'`) or use `avatar: require('')` for a remote image file
alertType | String | 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).
duration | Number | 3000 | Number of ms the alert is displayed
shouldHideAfterDelay | Bool | true | Tell the MessageBar whether or not it should hide after a delay defined in the `duration` property. If `false`, the MessageBar remain shown
shouldHideOnTap | Bool | true | Tell the MessageBar whether or not it should hide or not when the user tap the alert. If `false`, the MessageBar will not hide, but the `onTapped` function is triggered, if defined. In addition, if `false`, the `onHide` function will not be triggered. The property `shouldHideAfterDelay` take precedence over `shouldHideOnTap`. That means if `shouldHideAfterDelay` is `false`, the value of `shouldHideOnTap` is not taken into account, since the MessageBar will not ever be hidden

onHide | Function | | Callback function after alert is hidden
stylesheetInfo | Object | { backgroundColor: '#007bff', strokeColor: '#006acd' } | Background color and line stroke colors of the alert when alertType is equals to `info`

stylesheetExtra | Object | { backgroundColor: '#007bff', strokeColor: '#006acd' } | Background color and line stroke colors of the alert when alertType is equals to `extra`
durationToShow | Number | 350 | Duration of the animation to completely show the alert
durationToHide | Number | 350 | Duration of the animation to completely hide the alert
viewTopOffset | Number | 0 | Offset of the view from the top. That means the alert touch the top edge of the screen.
