A promise (deferred) is a very simple and powerful tool for asynchronous development. The CommonJS wiki lists several implementation proposals for the promise pattern. AngularJS has it’s own promise implementation that was inspired by Kris Kowal’s Q implementation. In this article I’ll introduce promises, it’s motivation and provide a useful tutorial about working with promises using AngularJS $q promise service.
I am developing a widget for websites. This widget lays inside an iframe in a website’s page. One of my users (which is a site owner) complained about a weird behavior of my widget. On pages where the widget was implemented, the browser’s back button didn’t work properly. Instead of navigating the user to the previous page on the website, the back button navigated the user to the previous page inside the iframe.
$http service of AngularJS allows us to communicate with a backend and make HTTP requests. There are cases where we want to capture every request and manipulate it before sending it to the server. Other times we would like to capture the response and process it before completing the call. Global http error handling can be also a good example of such need. Interceptors are created exactly for such cases. This article will introduce AngularJS interceptors and will provide some useful examples.
In this article I’ll explain what a provider is and what is the difference between a provider and other services declaration in AngularJS. Through this article I’ll also create a tidy Logger for your AngularJS application.
As we already know, AngularJS doesn’t come with an out of the box solution for data modeling. In the most abstract way, AngularJS lets us use JSON data as a model in the controller. As the time passed and my application grew, I realized that this modeling method isn’t powerful enough to fit my application’s needs. In this article I will present the way I dealt with data modeling in my AngularJS application.
I have made a css accordion using flexbox and I like to share it. This is how it looks like:
One day I was asked to add a text input component with an ability to choose a value from fixed list. After searching the web, I found several jQuery plugins that was able to solve my needs and much more. But, those components required many dependencies and weighed so much for my simple need. So I decided to write my own plugin. Easy Select requires jQuery only and takes 3kb minified (before gzip):
This article will guide you how to add user authentication to your single page application. On the back end side I will use Node.js and on the front end side I will use AngularJS. Although I used specific frameworks, you may apply the same technique for different back end and frond end frameworks (rails, Backbone, etc…).
The final application will look like this (without the horrible styling):
In this article I will show you how to build a pages slider that looks like those on our smartphones. At the end we will get this:
Backbone allows our users to browse our website without refreshing the page. Each page the user visits consists of several Backbone views which are replaced whenever the user navigates. Views reflect our data models and interact with each other. This can be done by listening and triggering events which add functionality to the page. Whenever the view is replaced, there is a need to clean up the removed view, unbind events and remove unmanaged structure.
This article suggests a solution to the views cleanup problem.
