The module consists of there elements - directive, service and provider.

Directive

notifications-bar element directive, should be placed once, typically right after <body> open tag.

<notifications-bar class="notifications"></notifications-bar>

<notifications-bar class="notifications" closeIcon="fa fa-times-circle"></notifications-bar>

The default is the glyphicon-remove icon so don't forget to import Glyphicons if you aren't defining a closeIcon attribute.

Possible to use as attribute, as well

<div notifications-bar class="notifications"></div notifications-bar>

Service

notification service is used by controllers (or other directives), to show notifications.

app.controllers('app', function ($scope, api, notifications) {
	api.get({resource: 'tasks'})
		.then(function (tasks) {
			$scope.tasks = tasks;
		}, function (error) {
			notifications.showError({message: error.message});
		});

	$scope.submitTask = function () {
		api.post({resource: 'tasks'}, {description: this.description})
			.then(function () {
				notifications.showSuccess({message: 'Your task posted successfully'});
			}, function (error) {
				notifications.showError({message: 'Oh no! Task submission failed, <em>please try again.</em>'});
			});
	}
});

Provider

notificationsConfigProvider is used to override some notifications bar defaults.

app.config(['notificationsConfigProvider', function (notificationsConfigProvider) {
	// auto hide
	notificationsConfigProvider.setAutoHide(true)

	// delay before hide
	notificationsConfigProvider.setHideDelay(3000)
}])

Settings

It is possible to setup the whole notifications bar module in module config and each notification separately in controller

Available options:

autoHide
hideDelay
acceptHTML
autoHideAnimation
autoHideAniationDelay

Please note, HTML support is only configurable at a global level. If HTML is to be supported, make sure to inject the 'ngSanitize' dependency.

var app = angular.module('app', ['ngNotificationsBar', 'ngSanitize']);

During configuration

app.config(['notificationsConfigProvider'], function (notificationsConfigProvider) {
	// auto hide
	notificationsConfigProvider.setAutoHide(true);

	// delay before hide
	notificationsConfigProvider.setHideDelay(3000);

	// support HTML
	notificationsConfigProvider.setAcceptHTML(false);
	
	// Set an animation for hiding the notification
	notificationsConfigProvider.setAutoHideAnimation('fadeOutNotifications');
	
	// delay between animation and removing the nofitication
	notificationsConfigProvider.setAutoHideAnimationDelay(1200);
	
}])

Override in controller

app.controller('main', function ($scope, notifications) {
	$scope.showError = function () {
		notifications.showError({
			message: 'Oops! Something bad just happened! (hides faster)',
			hideDelay: 1500, //ms
			hide: true //bool
		});
	};
});
