Hands-On JavaScript High Performance is your practical guide to optimizing various pieces of web and JavaScript like DOM, classes, and workers with Node.js. By building complete projects, you'll learn about emerging technologies like WebAssembly, Service Workers, and Svelte.js to prepare yourself for writing optimized code and build faster apps.
An example-driven guide covering modern web app development techniques and emerging technologies such as WebAssembly, Service Workers, and Svelte.js to build faster, secure, and scalable apps

Key Features

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

Book DescriptionHigh-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.

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

Who this book is forThis 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.

Justin Scherer has been professionally developing JavaScript applications for over 10 years. On top of this, he has worked in a variety of fields ranging from embedded systems to high-performance cluster applications. Justin has led development teams that utilize JavaScript on the web and on the server. He currently works for a large financial institution where he is leading the charge on developing highly performant front-end and middleware using JavaScript. On his off time, he has a handful of hobbies: playing the piano, going to concerts, repairing watches, reading, and spending time with his wife. His mind is constantly wandering to new areas where technology, especially web technology could prove useful.
