The JavaScript Ecosystem

In 2007 Steve Yegge in his famous ì The Next Big Languageî blog post, was speculating about how big JavaScript would become - and he was right! With innovations like V8, Node.js, CoffeeScript, client-side MVC frameworks, and more, it has become the fastest growing programming platform ever! In this tracks leading experts in the field will provide valuable insight into how they leverage JavaScript for building innovative products and services. Presentations will cover several issues like popular libraries and tools, motivations, best-practices, deployment patterns and more.

Testable JavaScript

10:20pm - 11:10pm

By: Mark Trostler

Testable JavaScript is a process. Whether starting with a blank slate or an already implemented application (or somewhere in-between) being able to test your JavaScript code simply, cleanly, and effectively is a necessary feature. Code that cannot be tested will be rewritten.

While JavaScript is unique due to the myriad of environments within which it runs, there are several tried and true ‘testable’ methodologies from other languages which also hold true for JavaScript. And of course there remain the unique challenges that JavaScript developers must face while writing and testing their code.
What patterns make code testable? Which anti-patterns hinder testing? What metrics and common sense guideposts can be used to measure the testability of our code? Once the process of creating testable code has started now what?

Join me to break down the process of writing testable JavaScript. We will investigate ideas, patterns, and methodologies that greatly increase the testability, and hence the maintainability, correctness, and longevity of your code. Whether you write client- or server-side JavaScript mastering this process will greatly enhance the quality of your code.
Testing Mobile Apps using Node.js, Appium, and Robots

2:50pm - 3:40pm

By: Jason Huggins

Appium is a new open source automation tool for testing native or hybrid applications on iOS and Android. Written in JavaScript and powered by Node.js, Appium is a Selenium WebDriver-compatible server. Appium can test apps in emulators and on real devices. There is also early support for testing with Tapster, a robot-controlled stylus on real devices. (The robot's powered by Node, too!)

Appium has two key tenants:
* You don't have to recompile your app or modify it in any way just to test automate it.
* You can write your tests in any language.

In this talk, I'll explain Appium's Node.js design, and show how to code simple tests to automate an app running in iOS and Android simulators and on real devices. There will be a few robot demos, too. Finally, I'll explain why I think robots like Tapster will be an important part of mobile test automation in the future.
Combining JavaScript with Other Languages on the Web

5:10pm - 6:00pm

By: Alon Zakai

JavaScript runs everywhere and is familiar to a huge community of developers, and consequently many applications are written in JavaScript these days. There are times however when other languages are desired, for example because of existing codebases, preferred language features, or performance. In this talk we'll discuss writing and deploying web applications that use both handwritten JavaScript and another language like C++ that has been compiled into JavaScript. We will present the advantages of that approach, open source tools like Emscripten and Embind that enable it, asm.js optimizations which let it run at near-native speeds, and several real-world examples of such projects.
Javascript Unconference

11:30pm - 12:40pm

By: Nitin Bharti

Meeting each other in the context of conversations we care about is why at QCon we are giving prime time to the unconference format; it creates a space for peer-to-peer learning, collaboration and creativity.

First we’ll father in a circle to be guided through creating an agenda using open space technology. Then there will be three three 20 minute time slots, each with 5 concurrent break out discussions that were designed by you.

Attendees often know more than the speakers! Bring your questions, ideas - be prepared to be surprised.
The past, present, and future of web apps

4:00pm - 4:50pm

By: Erik Bryn

There is an evolution underway with the way web applications are written. The move away from server generated HTML to fully client-side JS applications has ushered in richer user experiences, more competitive to those of native apps. Erik will talk about how we got where we are today and where he thinks we're going.
Surviving Big JavaScript Projects

1:40pm - 2:30pm

By: Anton Kovalyov

Every engineer working on Firefox has to deal with a large, bazaar-style project. Thousands of developers, both Mozilla employees and outside contributors, commit hundreds of patches every day. How do you manage such a project? And, if you're a new contributor, how do you find your way around the mountains of legacy code and implicit knowledge? This talk gives you an inside look into one of the biggest JavaScript projects and presents techniques to help keep your team's code quality on a high level while allowing your teammates to do what they do best: push tons of changes every day.
