Testing accessibility can be any or all of slow, expensive and frustrating, but it doesn’t have to be. Open source accessibility testing tools can help you find issues in a timely and useful way. Accessibility Developer Tools is a JavaScript library for automated accessibility testing of the DOM. We'll discuss how it works, and how it makes it easier for developers to test for accessibility.

A promise is a proxy for an eventual result, like an asynchronous version of return or throw, but they can also pipeline messages asynchronously to and from remote objects. A Promise type will likely be in ECMAScript 6, and many modern libraries use them already. In this talk, I will bring you up to speed with what they are and what you can do with them today…and what they “promise” for tomorrow.

90-Minutes: Front end development is harder than ever! Differing screen resolutions, changing browser support, varying network speeds and other considerations all jockeying for our attention during development. Fortunately, we have more powerful tools to help us develop, test and refine the amazing sites we build! Let's use those tools to automate all the front-end dev things...

It's time for video narratives to truly be of the web. Video shouldn't just be a one-way stream: it should create a dynamic, interactive, responsive visual narratives that leverage all the resources of the web, whether those are simply text, or complex visualizations or localized data. Data Docs, an experimental, open-source video platform, hopes to support and inspire a new iteration of....

The quality of modular web applications can be improved by having the right set of APIs. This talk highlights the recent API design best practices, from using static polymorphism for consistent naming, preventing dangerous convenience (e.g. Boolean trap), and avoiding unreadable code due to confusing semantics. Real-world examples and automated tools to recognize bad API will be shown as well.

Abstractions in FP can be daunting if you're not familiar with set theory or lambda calculus or category theory & all that. I'm certainly not. I'll translate some of the most important functional patterns & interfaces in JS directed towards us object orienters who may not have majored in math. You'll leave with a killer toolset and you'll weep at the beauty...if you have a heart.
Dan Tocchini (The Grid)

Web developers are expected to build increasingly sophisticated UIs faster, cheaper, with tools that have not evolved with the times. Why is the trivial task of centering an element with CSS so obtusely complex ?

HTML forms have been the bane of web developers for years. Not anymore! With HTML5 you may learn to love forms. Browsers now enable you to provide users with rich date GUIs, validate forms and provide validation feedback without JavaScript. JavaScript-free placeholder text, pattern matching, required fields, auto focus, error handling is now a reality.

Do you still need jQuery? Has it become a crutch? Can you get away with dropping jQuery as a dependency and use native browser APIs instead? For the majority of this session we will be looking at common jQuery snippets and show how to convert them either using native browser APIs or utilizing popular micro-libraries.

It's been scientifically proven that more diverse communities and workplaces create better products and the solutions to difficult problems are more complete and diverse themselves. Companies are struggling to find adequate talent. So why do we see so few women, people of color, and LGBTQ people at our events and on the about pages of our websites?
Pamela Fox (Khan Academy)
What if everyone learnt to program in middle school? How would that change the way that they learnt other subjects? How would it affect their personal life? Their career? It's kind of a crazy idea, but it might be crazy in a good way. In this talk, I'll lay down my ideas for how this could happen and what it might mean, based on my experience teaching programming online on Khan Academy.

In this talk, I will look at two of the technologies that lie at the basis of responsive web design: the viewport meta tag and CSS media queries. I will explain how viewport is being standardized as @viewport, and how many other new features in CSS, such as the resolution media query, object-fit, relative length units etc., can be used to create even more compelling responsive designs.

Based material from the book "RESTful Web APIs", this talk walks you through the creation of a great UI for a Collection+JSON media type API and then shows how minor changes on the server are automatically handled by the client without rewrites or redeploys. The same library can even used for different APIs with the same smooth results. Reusable libraries for hypermedia clients is a reality.

Young children playing with mobile devices don’t have a preconceived idea of what it means to tap, or swipe, or talk into the mic, or that only one little point of one hand should touch the screen at a time. They rely on trial and error and cues from the app. This session will cover intuitive gestures, interactivity cues, and element placement, as well as legal considerations for children's apps.
Ilya Grigorik (Google)
Performance is a feature, but what exactly is performance? Should UX be part of it and are there design principles that will help us deliver experiences that "feel faster"? What does it mean for a site to "feel fast" anyway and what is fast enough?

At Facebook we take the future of JavaScript seriously, and we go to great lengths to accelerate the adoption of new language features both within the company and without. Join us for a close look at some of our techniques for transpiling, desugaring, refactoring, and otherwise improving a very large JavaScript codebase.
Aaron Frost (Domo), Dave Geddes (Domo)
Across the board, the JavaScript community is thriving. This last year has seen unprecedented levels of adoption. Dave and Aaron will take a look at some of the reasons for the success of the JavaScript community, while also exploring some of the painful bits along the way.

Modern applications written in JavaScript are vulnerable to many of the same attacks, like XSS and CSRF, that threaten traditional web apps. But defending against them requires new tools and techniques. This talk will illustrate best practices for securing these apps, and introduce some of the security conventions and tools we've built into Meteor, a full-stack JavaScript framework.

If not programmed and configured in a security conscious manner, Node.js web applications expose attack vectors that can be exploited for severe technical and business impact. In this presentation, attendees will learn about possible security pitfalls and walk out with a cohesive action plan to effectively address these concerns and build resilient Node.js web applications.
Christine Sotelo (New Relic, Inc.)
Front-end performance bottlenecks and errors leave a lasting impression on your customers. This is not the impression you want. Christine will show you how to quickly identify problems in your front-end code and make sure your users stay happy and keep visiting your web app.

Developing large apps is difficult. Ensuring that code is consistent, well structured, tested and has an architecture that encourages enhancement and maintainability is essential. But, how do you achieve this when building HTML5 single page apps? In this talk you'll learn the main concepts to apply when building a front-end app that scales and how BladeRunnerJS can support the development process.

The field of user experience has proven in the last decade how research methodologies can significantly improve the usability, intuitability, and enjoyment of products. Yet API design is dominated by discussion of how one technology (HTTP) is most purely applied (REST/Hypermedia). User research and testing can elevate the level of design for APIs. I will present strategies for building great APIs.
Scott Hanselman (Microsoft)
How does the pervasiveness of JavaScript on the client change how we architect applications? We can create hundreds virtual machines in the cloud, but we are using the millions of visual machines that visit our sites every day?
