Book Description
JavaScript applications of today look a lot different from their predecessors of just five years ago. Because of this rapid growth in sophistication and capabilities,we've seen an explosion in JavaScript frameworks; the JavaScript development landscape is a fragmented one. To build large-scale JavaScript applications,we need more than just tools – we need scalable architectures. We create scalable JavaScript architectures by looking at what aspects of our application need to scale and why. Only then can we apply the best patterns and components to our architecture,scaling it into the future.
JavaScript at Scale will show you how to deal with scalability from a number of perspectives; addressability,testability and component composition.
The book begins by defining ‘scale’ from a JavaScript point of view,and dives into the influencers of scale,as well as scalable component composition and communication. We will also look at how large-scale architectures need the ability to scale down,and recover from failing components,as well as scale up and manage new features or a large user base.
Filled with real-world JavaScript scaling scenarios,and code-first examples,JavaScript at Scale is your guide to building out applications that last. Each topic is covered in a way that it can be applied to your own unique scenarios; by understanding the fundamentals of a scaling issue,you’ll be able to use that knowledge to tackle even the most difficult of situations.
The code examples follow the same approach,using ECMAScript 6 syntax that can be translated to the framework of choice.
