A Guide to Building Your First Ember.js App

by Balint Erdi

As modern web applications do more and more on the client-side (the fact itself that we now refer to them as “web applications” as opposed to “web sites” is quite telling), there has been rising interest in client-side frameworks. There are a lot of players in this field but for applications with lots of functionality and many moving parts, two of them stand out in particular: Angular.js and Ember.js. Angular.js has already been introduced on this blog, so we're going to focus on Ember.js in this post, in which we'll build a simple Ember application to catalog your music collection. You'll be introduced to the framework's main building blocks and get a glimpse into its design principles.

A Year Building a WebRTC Application: Lessons in Startup Engineering

by Alexandre Mondaini Calvão

I've been an Engineer at Toptal for just about one year now, working on the same project since I joined the network: Ondello, a service that connects doctors and patients over WebRTC. When I first joined Ondello, I was hired as a Senior Ruby on Rails Developer, tasked to build a service up from scratch. These days, we're a team of multiple developers working on a fairly large, complex system. With this post, I'd like to share the story behind Ondello. Specifically, I'd like to talk about: how a simple application became not-so-simple, and how our use of cutting-edge technologies posed problems I'd never considered before.

A Step-by-Step Tutorial for Your First AngularJS App

by Raoni Boaventura

If you haven’t tried AngularJS yet, you’re missing out. The framework consists of a tightly integrated toolset that will help you build well structured, rich client-side applications in a modular fashion—with less code and more flexibility. One of the reasons I love working with AngularJS is because of its flexibility regarding server communication. Like most JavaScript MVC frameworks, it lets you work with any server-side technology as long as it can serve your app through a RESTful web API. But Angular also provides services on top of XHR that dramatically simplify your code and allow you to abstract API calls into reusable services. As a result, you can move your model and business logic to the front-end and build back-end agnostic web apps. In this AngularJS tutorial, we'll do just that, one step at a time.
