Empowering the "mobile web"

The document summarizes techniques for improving JavaScript performance in web applications. It discusses how JavaScript execution blocks the browser UI thread, leading to unresponsive user experiences if scripts run for too long. It then provides recommendations to limit JavaScript execution times to under 50ms and describes load time techniques like placing scripts at the bottom of the page, combining files, and loading scripts dynamically or deferring their execution to improve page load performance.

React is a UI library that is changing the way web applications are written. While there are many benefits to using React, managing an application's complexity as it scales is one of the most powerful.

Electron is a fantastic tool for creating cross-platform apps with HTML, CSS, and JavaScript that look and feel relatively native to the hosted Platform. In this presentation I'll give a quick overview of what's possible.

This document introduces web workers, which allow JavaScript code to perform processor-intensive calculations without blocking the user interface (UI) thread. Web workers allow web pages to run multiple scripts simultaneously, improving performance for tasks like live syntax highlighting, crunching large amounts of data, and smooth animations. They work by executing scripts in background threads separate from the main script, so the UI thread is not blocked. Developers create and communicate with worker threads to offload processing work from the UI thread.

Webpack tutorial with tips for Symfony users. Topics covered include: current frontend trends, setup, loaders, dev tools, optimization in production, bundle splitting and tips and tricks for using webpack with existing projects. Symfony Munich Meetup 2016.

This document discusses web workers, which allow JavaScript to execute tasks in background threads apart from the main execution thread. It covers the need for web workers due to JavaScript's single-threaded nature. There are two types of web workers - dedicated workers which are linked to a single script, and shared workers which can be accessed by multiple scripts. The document outlines the web workers API, how to communicate with workers using message passing, and provides examples of dedicated and shared workers. It also discusses browser support for web workers and how to check for support.

The document discusses responsive interfaces and how to keep the user interface responsive when executing JavaScript. It explains that the UI thread is used for both drawing updates and running JavaScript, so no updates can happen while JavaScript runs. It recommends keeping JavaScript execution under 50ms to avoid unresponsiveness, and describes using timers and web workers to split processing over multiple ticks to keep the UI responsive.

The document discusses lessons learned from examining popular jQuery plugins. It summarizes 30 top plugins, describing why each was created and how it grew. Key takeaways are that authors build plugins to make something better, for fun/exploration, or client needs. Managing features and user feedback is challenging. The best plugins have great demos, documentation, browser support testing, and are fun. The author is available for questions.

An introduction about JavaScript web workers I gave at BerlinJS on the 18th of July 2013. It introduces the concept of web workers for simple parallel processing in client side JavaScript.

Progressive Web Applications (PWA) is a comprehensive term describing web applications that implement a base set of browser platform features like HTTPS, Web Manifest and Service Workers. But it bleeds beyond the scope of an application's code because browsers are enabling qualified web applications to offer the same user experiences native application enjoy. This includes prominent home screen placement, push notifications, eliminated browser chrome and app store placement.

Vue.js is a JavaScript framework that provides two-way binding between DOM and JavaScript, a template language for declarative rendering, and supports installation via npm, direct download, or a script tag. It allows defining where rendering will occur, setting up data, and rendering data to the DOM. Components provide reusability through templates, logic, and styles. Additional features include routing, state management with Vuex, and use of the Vue CLI for scaffolding single file components.

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.

The document summarizes key aspects of building Firefox OS to address issues with the mobile web. Firefox OS is Mozilla's attempt to make the web a first-class citizen on phones and tablets by starting with the web stack rather than trying to add the web to an existing OS. It has launched in several countries and aims to be an affordable alternative to feature phones and closed platforms. The architecture is based on Linux, Gecko, and web technologies. It provides predictable HTML5 support and addresses performance, fragmentation, security and hardware access through its design and web APIs.

This document summarizes the Firefox OS, an open web platform for building mobile apps and customizing the user interface using HTML5, CSS, and JavaScript. It outlines key web APIs, the process for developing and publishing open web apps, and the different types of apps including regular web apps, installed web apps, and privileged web apps with additional capabilities. Security levels and permissions for APIs are also discussed.

Firefox OS is an open source operating system built using HTML5 that aims to fulfill the promises made by HTML5 as a platform. It gives developers full access to device hardware through Web APIs while allowing app distribution through the web. The OS is already available on low-cost devices in certain markets. It uses the Gecko rendering engine and a simple architecture based on Linux and Android. This allows it to provide predictable HTML5 support and security for web apps. Developers can build apps using standard web technologies and distribute them via the Firefox OS marketplace or by installing them directly from the web.

This document provides an overview and introduction to the webOS platform. It discusses the webOS architecture including application architecture using stages and scenes. It covers building a basic "Destroy World" app using the command line tools. It also discusses the webOS emulator, advanced APIs like camera, storage and accelerometer access. Finally it discusses submitting apps to the webOS app catalog and a promotion for hot new apps.

Firefox OS allows developers to build apps and customize the user interface using HTML5, CSS, JavaScript, and Web APIs. Apps are developed as regular web apps, with the addition of an app manifest file. Apps can be published to the Firefox Marketplace or installed directly. The Firefox OS platform provides both regular web APIs as well as more privileged APIs that require permissions. Future plans include additional APIs for features like spell checking, peer-to-peer connectivity, and WebRTC. Developers can get help through IRC channels or mailing lists and try things out using emulators, boilerplate apps, and the Firefox OS developer preview.
