angular-flash

A simple lightweight flash message module for AngularJS and Bootstrap.

Demo

angular-flash | jsfiddle | codepen

Install

npm

You can also find angular-flash on npm

$ npm install angular-flash-alert

Bower

You can Install angular-flash using the Bower package manager.

$ bower install angular-flash-alert --save

Add the Following code to the <head> of your document.

<link type="text/css" rel="stylesheet" href="dist/angular-flash.min.css" />
// If you are using bootstrap v3 no need to include angular-flash.css
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script src="dist/angular-flash.min.js"></script>
// Do not include both angular-flash.js and angular-flash.min.js

Add ngFlash dependency to your module

var myApp = angular.module("app", ["ngFlash"])

Include directive below in your HTML template.

<flash-message></flash-message>

Configure

You can configure angular-flash by two ways:

Add attributes on the <flash-message> directive.

<flash-message
    duration="5000"
    show-close="true"
    on-dismiss="myCallback(flash);"
></flash-message> 
<!-- 
5000ms as the default duration to show flash message.
Show the close button (x on the right).
Call myCallback with flash dismissed as parameter when flash has been dismissed.
-->

Set configuration with flashProvider.

app.config((FlashProvider) => {
    FlashProvider.setTimeout(5000);
    FlashProvider.setShowClose(true);
    FlashProvider.setOnDismiss(myCallback);
});

Use a custom template

By default, angular-flash use the Bootstrap flash standard template, but you can set your own template.

By giving it in the Js: use .setTemplate(...) with the template in parameter.

app.config((FlashProvider) => {
    FlashProvider.setTemplate(`
        <div class="my-flash">{{ flash.text }}</div>
    `);
});

By giving it in the HTML: use .setTemplatePreset('transclude') with the template transcluded in the <flash-message> directive.

app.config((FlashProvider) => {
    FlashProvider.setTemplatePreset('transclude');
});
<flash-message>
    <div class="my-flash">{{ flash.text }}</div>
</flash-message>

How to use

Inject the Flash factory in your controller

myApp.controller('demoCtrl', ['Flash', function(Flash) {
    $scope.successAlert = function () {
        var message = '<strong>Well done!</strong> You successfully read this important alert message.';
        var id = Flash.create('success', message, 0, {class: 'custom-class', id: 'custom-id'}, true);
        // First argument (string) is the type of the flash alert.
        // Second argument (string) is the message displays in the flash alert (HTML is ok).
        // Third argument (number, optional) is the duration of showing the flash. 0 to not automatically hide flash (user needs to click the cross on top-right corner).
        // Fourth argument (object, optional) is the custom class and id to be added for the flash message created. 
        // Fifth argument (boolean, optional) is the visibility of close button for this flash.
        // Returns the unique id of flash message that can be used to call Flash.dismiss(id); to dismiss the flash message.
    }
}]);

Flash types

  • success
  • info
  • warning
  • danger

Methods

These methods are mostly for internal usage but can be used also from outside.

Flash.dismiss(1);
// Dismiss the flash with id of 1. Id is not the index of flash but instead a value returned by Flash.create()
Flash.clear();
// Dismisses all flashes shown.

Animating

You can animate the flash messages via traditional Angular way by including ngAnimate as a dependency of your application and then defining the CSS transitions for different classes (ng-enter, ng-move, ng-leave) provided by Angular.

Example:

.alert.ng-leave {
  opacity: 1;
  transition: opacity 1.5s ease-out;
}
.alert.ng-leave-active {
  opacity: 0;
}

Multiple flash containers

You can send flashes to different containers by naming them and specifying their name in the config you pass to the Flash.create function.

<flash-message name="flash-fixed"></flash-message>
Flash.create('success', 'Hooray!', 0, {container: 'flash-fixed'});
