HTML5 Web Workers-unleashed

No one wants a slow loading, slow reacting application. As page weight has increased so has the dependency on JavaScript to drive rich user experiences. Today many pages load over 2MBs of JavaScript, but is this healthy? Do your scripts and dependencies perform well? In this session we will review common JavaScript performance bottlenecks, how to detect them and how to eliminate them. This session will review common bad coding syntax, architecture and how to replace them with better alternatives. You will also be exposed to caching, code organization, build and deployment best practices that produce the best user experiences. Finally, you will see how to use the navigation timing and performance timing APIs to fine tune your applications to produce a fast, lean application your customers will love.

Benefits for a medical conference app replacement are discussed.

Bower, Grunt, and RequireJS are just a few tools that have been re-shaping the frontend development world, replacing cluttered script tags and server-side build solutions with a sophisticated, but sometimes complex approach to dependency management and module loading. In this talk, we'll put on our trendy frontend developer hat and find out how these tools work and how they differ from what we might be used to. Most important, we'll see how using tools like this might look in Symfony2 and how our application can be a friendly place for a frontend guy/gal.

Do you want to leverage HTML, CSS and JavaScripts APIs to deliver rich user experiences that outlive the framework du jour? Do You want to understand good front-end application architecture and performance principles. Then you want to build applications in Vanilla JS. Despite popular belief Vanilla JS is not as difficult to master and implement as you might think. In this tutorial Chris Love will demonstrate how to apply many common web performance optimization, good architecture and tricks to build a fast, native-like application user experience customers desire without dependency on large, fast food frameworks. This tutorial will demonstrate the following concepts: - Applying the 14kb Rule for Instant Loading - Markup Management - Eliminating Excess AJAX Calls - Working With and Around Application Cache - Applying Service Workers and HTTP/2 For Even Better User Experiences - Leveraging common browser APIs & good architecture

Everybody knows Javascript is single-threaded and that it shares this same thread with other browser-related processes such as painting and compositing. There are several techniques to implement pseudo multithreading in JavaScript; however, during this talk we will focus our attention on how to use and debug the Service Worker API. Our end goal is to explore practical use cases in order to simplify the process to render complex user interfaces and transitions in a browser.
