schedule 09:00 AM - 10:00 AM place Grand Ballroom

You can find solutions to thousands of jQuery problems on the Internet in blog posts, StackOverflow answers, or on Github. The problem is, many of those answers and code snippets are very obsolete! The web development world of 2006 that jQuery was born into is very different than the world of 2015, and jQuery has evolved to keep up. Yet there are still features inside of jQuery that only remain because of compatibility concerns, not because they're a good idea in modern web development.

This talk will discuss features of jQuery that are best to avoid if you want a fast web site or HTML app that works with the widest range of browsers--even browsers that haven't yet been released! You'll also learn how using some of these features can make it very hard to follow modern practices such as Responsive Design. For each feature, you'll learn the modern 2015 way to do each of these tasks.

    • ... and grew...
    • ... and keeps growing!
  • New versions of jQuery in January 2013 (1.9, 2.0)
    • Many bad APIs and practices removed
    • jQuery Migrate plugin helps developers find problems
    • Allows older plugins to still work, but it's a crutch

    “Internet of things” is the concept of basically connecting any device with an on and off switch to the Internet.

    IoT has been possible through devices like Arduino, Raspberry Pi and many more. Initially, working with them started with C/C++. Now, you can do the same with different languages like Python, Ruby, JavaScript, Go and more languages are coming to this landscape. NodeJS, frameworks and npm has built an environment like no other. Just with the the fundamental knowledge of JavaScript and reading through API docs, one can easily get started with IoT. That's what I will be showing.

    I would like to share my approach, resources etc I learned from and show things that are possible.

    Maintaining a jQuery plugins website is hard but equally rewarding. In this talk I am going to outline some of the initial difficulties I have faced and its corresponding learnings. jquer.in also played an important role into how I become a Front End Developer. Even now it plays a huge role into improving my writing skills, coding skills, contacts.

    Over the past decade, eXtreme Programming practices like Test-Driven Development (TDD), Behavior Driven Developer (BDD), Refactoring and Continuous Integration have fundamentally changed software development processes and inherently how engineers work. Practitioners claim that it has helped them significantly improve their development speed, design quality and responsiveness to changing requirements. Software professionals across the board, from Internet startups to medical device companies to space research organizations, today have embraced these practices. But can these practices be applied to front-end development? Especially jQuery plugin development?

    This demo will show how we can test drive a jQuery plugin with the help of various patterns, strategies, tools and techniques. Participants will understand how they can apply this approach for testing any jQuery code.

    What do SASS, LESS & Stylus all have in common? They all mimic features we already have, natively, in JavaScript. Variables, Functions, Inheritance, Modularity and a whole lot more are all solved problems. Let's change how we think about approaching creating our styles and utilize the power of the most ubiquitous language already within our projects. You'll learn just how easy and powerful it it is to write JavaScript to generates CSS. This will change your world!

    The list of solidified ES6 has kept growing and we, on the client side, just get greener with envy. Many of these new features won’t be supported in a broad base of browsers for years to come, but there is hope for us nonetheless. While we don’t have the ease of flipping a command line flag, like node, to bask in the warm sunlight of ES6 sugar, we can build a system that gives us similar results.

    Using a combination of shims and transpilers, we can enjoy these new language features while still maintaining support for all of the browsers you’d need. I'll first explain some of the great new additions to the JavaScript programming language and example use cases with code that take advantage of ES6's elegance for client side development. I will go through the details of setting up a development environment with source maps for debugging the code that you wrote, rather than what is generated by a transpiler.

    After listening to this talk, I hope your jealousy will be soothed, and I know that your curiosity will be satisfied.

    Famo.us is a pure javascript UI framework which deviates from traditional web development approach around declerative coding & brings in the ability to marry different visual elements under the HTML5  and Open Web umbrella ( such as CSS3, Canvas, SVG & WebGL ) to create absolutely stunning user interfaces. In this talk we are going to have a look at some of the capabilities of famo.us by means of a few demonstrations. We will demonstrate a few web applications built with Famo.us, right from the basic apps, to the more engaging ones , all the way to the more advanced applications which can arguably thwart any traditional multimedia content consumption platform in favour of the web.

    I’d like to talk to you about what memory leaks are, how they occur and, most importantly, why you should care. With JavaScript becoming ever so prominent, it’d be fun to get to know the common caveats and understand what happens under the hood a little better.

While jQuery allows us the abstraction powerful abstraction around cross-browser API differences, it can also prove to be a "security nightmare" due to the ways of usage.This session will take you through common jQuery security mistakes including XSS, data validations, inline events, URL encoding, hosted plugins and how to avoid them.

This talk will highlight many of the efforts we are currently focussed on and we'll also dive into some of the projects we've been working on with the community to give you an idea of current outcomes of those efforts and demonstrate some of the uses of those projects. Though jQuery and its related projects are still important to the web, this talk will focus more on the other efforts the jQuery Foundation is involved in that many may not know about.

    Over the past seven years, jQuery UI has identified and solved many common problems for web developers. Often times, the problems don't apply just to users of jQuery UI, or even jQuery Core. In these cases, we try to solve the problem in the best way for the largest audience, rather than creating an isolated solution within jQuery UI. We're able to do this by working with the community and bringing together various groups to collaborate on solutions. In this talk, I'll discuss how this concept is at the heart of the jQuery Foundation and explain some of the projects that have been born out of jQuery UI.

    Advances in JavaScript, HTML5, and the proliferation of related JavaScript libraries, have laid the technological foundation for data visualization. This current and evolving technological landscape, with a wealth of data from innumerable sources, is offering a vast opportunity for Web designers, developers and data analysts to be key players in transforming raw data into meaningful representation. This workshop demonstrates the power and flexibility of modern JavaScript and JQuery libraries to present you best-of-breed visualizations with a real-world use case.
