React is a JavaScript library developed for one main reason-to build reusable UI components that present ever-changing data. The React philosophy is to focus solely on the user interface. In model-viewcontroller (MVC) terminology, React is the view. Because it has to work with models and other libraries, it's designed to play nicely with pretty much any other framework, router, style, and model library. And it's well supported-React emerged from Instagram and is now used by Facebook, Asana, Khan Academy, and Atom among many more. React Quickly is for anyone who wants to learn React.js fast. This handson book teaches needed concepts by using lots of examples, tutorials, and a large main project that gets built throughout. It starts with the basics, including how React fits into applications, JSX, and handling states, and events. Next, it explores core topics like components, forms, and data. Finally, the book dives into React integration topics, like unit testing and isomorphic JavaScript with Express.js, and Gulp. Key Features: * Uses videos to supplement learning * Chock full of examples * Gets readers using React quickly This book is for web developers who have some JavaScript experience. About the Technology: React is a JavaScript library developed for one main reason-to build reusable UI components that present ever-changing data.

Is Responsive Web Design (RWD) slowing your site down? It doesn't have to. With this concise book, you'll learn practical techniques for improving performance with RWD, including a default set of guidelines you can use as an easy starting point. Web performance researcher and evangelist Guy Podjarny walks you through several existing solutions for dealing with RWD performance problems, and offers advice for choosing optimizations that will be most useful for your needs. RWD performance problems stem from excessive downloads of resources, including images, JavaScript and CSS, and HTML--downloads designed to let your web application adapt to different screen sizes. Podjarny presents a series of increasingly larger-scope solutions to each issue, including client-side techniques and RESS (Responsive + Server Side Components). Address performance issues by starting with Podjarny's default guidelines Use a JavaScript image loader and an image transcoding service to create Responsive Images Reduce JavaScript and CSS downloads with asynchronous scripts, conditional loading, and multi-viewport CSS Prioritize resources to avoid excess content in RWD and defer the load of any content that's not critical Explore server-side Adaptive Delivery and RESS solutions as an alternative to "pure" RWD Guy Podjarny, or Guypo for short, is the Chief Technology Officer (CTO) of Akamai's Web Experience business unit.
