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 jаvascript. 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 jаvascript 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 jаvascript 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 jаvascript 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 jаvascript to run it on a browser
