Key benefits

  • Discover effective techniques for accessing DOM, minimizing painting, and using a V8 engine to optimize JavaScript
  • Understand what makes the web tick and create apps that look and feel like native desktop applications
  • Explore modern JavaScript frameworks like Svelte.js for building next-gen web apps

Description

High-performance web development is all about cutting through the complexities in different layers of a web app and building services and APIs that improve the speed and performance of your apps on the browser. With emerging web technologies, building scalable websites and sustainable web apps is smoother than ever. This book starts by taking you through the web frontend, popular web development practices, and the latest version of ES and JavaScript. You'll work with Node.js and learn how to build web apps without a framework. The book consists of three hands-on examples that help you understand JavaScript applications at both the server-side and the client-side using Node.js and Svelte.js. Each chapter covers modern techniques such as DOM manipulation and V8 engine optimization to strengthen your understanding of the web. Finally, you’ll delve into advanced topics such as CI/CD and how you can harness their capabilities to speed up your web development dramatically. By the end of this web development book, you'll have understood how the JavaScript landscape has evolved, not just for the frontend but also for the backend, and be ready to use new tools and techniques to solve common web problems.

Who is this book for?

This JavaScript book is for web developers, C/C++ programmers, and anyone who wants to build robust web applications using advanced web technologies. This book assumes a good grasp of Vanilla JavaScript and an understanding of web development tools, such as Chrome Developer tools or Mozilla’s developer tools.

What you will learn

  • Explore Vanilla JavaScript for optimizing the DOM, classes, and modules, and querying with jQuery
  • Understand immutable and mutable code and develop faster web apps
  • Delve into Svelte.js and use it to build a complete real-time Todo app
  • Build apps to work offline by caching calls using service workers
  • Write C++ native code and call the WebAssembly module with JavaScript to run it on a browser
  • Implement CircleCI for continuous integration in deploying your web apps

As a professional programmer with over 30 years experience, I was intrigued about the premise of using JavaScript for high-performance web applications. The industry is ripe with Web Programmers, and books on the subject seem to stem from either the front-end or back-end programming. This book approaches the subject from both aspects. It takes the reader through the steps in both logic and by example for utilizing JavaScript in High Performance (i.e. high speed and high bandwidth) applications.I call this book a journey, as it moves the reader from the requirements for high-performance tools through DOM and API calls, Streams, Service Workers to Web Assembly. There are even brief glimpses into HTTP3 and Database applications within the browser. It appears to be a well thought out process, that although some subjects might be controversial amongst web programmers, the author expresses their view in a logical manner. This book is a great tool for those who may be interested in generating optimized code, something that in my view we need to concentrate on more. It is also for those who may be new to the field, as it compiles all of the necessary information into one succinct manual/story.I purchased the hard-copy of this book with great hopes that it would meet up with my expectations and it certainly did. The formatting and examples were easy to read. I also want to note that the examples appear to be skeletal in nature, making them easy to enter, test and modify for my own use. Well worth the money.

Book about anything and nothing at the same time. Title is absolutely misleading.
