Build Reactive Websites with RxJS: Master Observables And Wrangle Events
by Randall KoutnikUpgrade your skillset, succeed at work, and above all, avoid the many headaches that come with modern front-end development. Simplify your codebase with hands-on examples pulled from real-life applications. Master the mysteries of asynchronous state management, detangle puzzling race conditions, and send spaceships soaring through the cosmos. When you finish this book, you'll be able to tame the wild codebeasts before they ever get a chance to wreck your day. The front-end world can be fraught with complexity. The RxJS library offers a solution: Observables. Observables merge other JavaScript asynch mechanisms such as callbacks and promises into a new way of looking at data. Instead of dealing with objects and keeping track of their state, Observables view asynchronous events as a stream. RxJS provides you the tools to manage, manipulate, and process Observables to simplify and speed up your front-end applications. Never fear, you're in exactly the right place. Don't worry about getting stuck in a mire of theory. Start off with the basics, building small applications that illustrate deeper points. Take those building blocks and apply them to much more complex problems like handling asynchronous state and dodging race conditions before they happen. Once you've got a handle on complex problems, take a leap into architecture, discovering how to structure an Observable-based application both without a framework and in the land of Angular 2. After mastering Observables, switch gears to building a canvas-based game, demonstrating your deep understanding of the flexibility of Observables. Master the Observable with RxJS, and make your asynchronous JavaScript code that much cleaner and simpler. What You Need: Any major browser and text editor, as well as the current versions of git, NodeJS, and npm.

Develop your own theme using standard HTML and CSS, using Hugo’s powerful templating features to organize your site’s components. Create your site’s content with HTML or Markdown and use Hugo’s content templating features to build new content quickly. Build a fully-featured blog with archive pages, tagging, and pagination, and integrate an external commenting system to provide interactivity. Use data from front-matter, site-wide configuration, and external JSON sources to add content, and generate JSON others can use. Integrate JavaScript with your site to create a search engine. Get Hugo working with Webpack so you can leverage the wider web development ecosystem, and explore ways to publish your site to various services.
