Vue JS is a progressive framework for building user interfaces. It uses a component-driven approach and features like reactivity and computed properties that make it possible to build desktop, mobile, and web applications. Some key features include reactive data binding, conditional rendering, mixins, slots for content distribution, and Vuex for global state management between components. Asynchronous and dynamic components add flexibility. Vue shares similarities with React in using virtual DOM and components but differs in file structure and size.

I believe ServiceWorker is one of most important specifications for the next web world. Offline and its technologies are very friendly concepts to native application developers. But, now I think front-end developers have to know that for stepping into new paradigm. With ServiceWorker, you can make your web application can run offline, and it also means you can make your web application load extremely fast. I've told about ServiceWorker very briefly in this slide. But you can understand how ServiceWorker runs on. If you want to know its usage, I highly recommend Topeka, which is a polymer demo application at google I/O 2014, that also includes material design and ServiceWorker in inside of it. If you want to know ServiceWorker some more or in detail, I'd like to recommend to read the following, written by Jungkee Song, one of authors of this spec. http://www.slideshare.net/jungkees/service-workers
Sooner or later, any application needs to be released. And before that, it needs to be tested. Ideally! The purpose of this talk is to explore Nightwatch as a testing framework, how to set up an automated CI system using Travis and using SauceLabs as a browser farm.

This document discusses optimizing React and Webpack applications for production. It recommends: 1. Not optimizing prematurely and ensuring engineering and product goals are aligned before optimizing. 2. Understanding available optimization options at build time like minification, code splitting, and using production builds of dependencies, and at runtime like server-side rendering and component lifecycle methods. 3. Instrumenting the application to measure performance metrics like bundle size, load time, and render time to identify optimization opportunities. 4. Setting meaningful benchmarks based on the actual user experience expected, rather than arbitrary metrics, to determine what constitutes acceptable performance.
This document discusses module bundling tools for JavaScript applications. It introduces the problems of growing code complexity and need for optimized delivery of code. It then summarizes two popular module bundling tools: Webpack and jspm.

It will also cover lessons learned as we used MongoDB to rapidly develop and scale Doodle or Die.
NPM scripts allow developers to run predefined scripts at different stages of installing, publishing, and interacting with packages. These scripts are defined in the package.json file under the "scripts" key. Common script names include preinstall, install, postinstall, prepublish, publish, and postpublish. NPM versioning follows semantic versioning principles where versions are denoted as MAJOR.MINOR.PATCH. Dependencies can specify version ranges like tilde (~), caret (^), and hyphen (-) to control updates. Private NPM repositories and shrinkwrapping help ensure reproducible builds across environments. Scoped packages allow publishing packages under a unique namespace.
This document discusses using NPM scripts as a build tool. It covers setting up scripts in the package.json file to automate common tasks like linting, testing, building assets, and running dev servers. Examples are provided of setting up scripts for CSS preprocessing, bundling JavaScript, running tests, and more for both AngularJS and React projects. Chaining, piping, and running tasks concurrently with NPM scripts is also covered.

Video at http://www.youtube.com/watch?v=HaJnhYPLvx0 Large Drupal projects will generally have a themer or five working alongside the developers, site builders and designers. Themers are the magicians who transform what Drupal wants to do into what the designer wants it to do. Smaller projects also usually need someone on the team who can make sense of Drupal's output, knows more CSS and JS than anyone else and can configure Views with their eyes closed. The thing is — and whisper this, if possible redundancy concerns you — we can bypass the themer entirely. With some simple configuration, a site builder can get Drupal to output exactly the semantic, lightweight markup that any modern front-end designer would be proud of. The designer can be left alone to write the most appropriate HTML, CSS and JS, while the site builder need only choose a couple of options when putting together content types, views and panels to make Drupal behave. A friendly developer may have to lend a hand every now and then, but that’s it. You can get rid of the themer altogether. http://2013.drupalcamplondon.co.uk/session/death-themer
