In one of our project’s test code, we have to create many objects asynchronously and use them later in our tests. Our codebase is promise-based, so we have to chain these promises in a way that makes it possible to access all the variables we want in later time. There are many ways to do this, which we’ll explore.

Catberry was developed to help in creating "isomorphic" Web applications. Isomorphic applications are apps that use the same codebase to run from both server and client-side environments. This means you write the code only once, and deploy it the way you want. Catberry handles all the differences between these two environments, and will make sure the normal JavaScript modules that would need a server-side environment to run will execute without errors inside a browser. The application fits best when developing single-page applications (SPAs) and is also very well documented, helping developers new to the platform easily get acquainted to all of its features. Catberry uses modern technologies like HTML 5, Browserify, Connect, and Express, works on most modern browsers, and can also be extended via dedicated packages. Main features:

Two-way data-binding is such an important feature - align your JS models with your HTML view at all times, to reduce boilerplate coding and enhance UX. We will observe two ways of doing this using native JavaScript, with no frameworks - one with revolutionary technology (Object.observe), and one with an original concept (overriding get/set). Spoiler alert - the second one is better.

I will teach you how to take advantage of the MEAN stack in becoming a full-stack JavaScript developer. Node.js was created by Ryan Dahl and it’s basically a platform built on Chrome’s JavaScript runtime called V8, whose greatest advantage over other JavaScript engines is the compiling of JavaScript code to native machine code before executing it. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

It’s fairly trivial to add a ‘drag and drop’ interface to Ember.js with html5, without the need for external libraries, although the caveat is that mobile browsers don’t (yet) support html5 drag and drop. The basic premise is to create 2 components:
Using transclusion, we can then easily add our ‘drag and drop’ functionality into our Ember application with different UI.

Because Ember is well designed for asynchronous routing, it’s really easy to add application loading messages by making use of the little known global loading route that you get for free. Let’s get started! We’re going to create a few things:

When integrating node-webkit and angular, I found that I cannot run e2e test in the default chrome browser. It was because node-webkit allows us to use local node packages, which chrome does not support. After playing around these toys for a while, I think I have just figured out how to run e2e test in the context of node-webkit.

Flow is a static type checker for JavaScript. It can be used to catch common bugs in JavaScript programs - such as silent type conversions, null dereferences and so on - often without requiring any changes to your code. It also adds type syntax to JavaScript, so that developers can express invariants about their code and have them maintained automatically. Flow is used at Facebook but remains very much a work in progress.

In this post, we are going to build a desktop application that is like your typical one to one chat client. Where, a user logs in, sees a list of other users. And can chat with any of them. This app is called Chatter. As you can see from the above demo, we have used Firebase as our data store to manage the user’s presence and their chat messages. And also, if you did notice, when User B sent a new message to User A, a new chat window opened automatically, like a typical chat app. We will take a look at how all the above can be achieved. So, let us get started on building Chatter.

Sometimes you want to poll an API for new data periodically. Sometimes you depend on properties that change over time, but are out of Ember's control. Fear not, Ember's run.later has you covered. If you want to re-evaluate a computed property on a schedule, you need to depend that property on a property that changes over time. Turns out that creating such a property is fairly simple.

Highcharts is one of the better supported and developed front end charting libraries out there, and it makes creating standard charts a breeze. If you have a custom chart the likes of which the world has never seen however, you might be better off building it in something like D3.js. If all you need is a vanilla chart in your Ember app, read on. Implementing Highcharts in your Ember application so that it live binds to your data is simple, and really highlights the power of Ember.

In this article, we will create a SPA using ASP.NET MVC, WEB API and Angular.js. Angular.js is a Model-View-* JavaScript based framework for developing SPA applications. Similarly ASP.NET Web API is a good fit for providing data for these type of applications. SPA is the requirement of this new generation of web applications. It provides an easy interaction with WEB interfaces for users looking for a Desktop like experience on the Web. A mashup of client-server technologies like Angular.js and ASP.NET Web API helps you create enterprise ready SPA applications.
