Overview of this book

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.

For this book, it is recommended to get the current version as the module support is better.

For Windows, all we need to do is download and run the executable. For OS X and Linux, this should also be simple. For Linux users especially, there may be a version in the repository manager for a specific distribution, but this version may be old or line up with the LTS version. Remember: we want to be running the latest version of Node.js.

Once we have it installed, we should be able to invoke the node command from any command line (Linux users may have to invoke the Node.js command since some repositories...
