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.

Summary

Svelte is an interesting framework in which we compile our code to Vanilla JavaScript. It utilizes modern ideas such as modules, templates, and scoped styling. We are also able to create reusable components in a simple manner. While there are even more optimizations that we could make to the applications that we have built, we can see how fast they truly are. While Svelte may not become a mainstream choice for application development, it is a great framework to see many of the concepts we have explored in previous chapters.

Next, we will take a break from the browser and take a look at how we can utilize JavaScript on the server utilizing Node.js. Many of the ideas that we have seen here will be applied there. We will also see new ways of coding our applications and how we can use one language across the entire web ecosystem.
