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

In this chapter, we learned how service workers can turn our applications from always being online to systems where we can create truly always working applications. By saving the state, handling requests locally, enriching requests locally, and even saving requests for offline use, we are able to handle the full state of our application.

Now that we have looked at creating rich web applications from both the client side and the server side with JavaScript, we will start to take a look at some advanced techniques that we can use to create highly performant applications that we only thought were possible through native application code. We can do this by utilizing C, C++, or Rust.

However, before we get to that, one piece of application development that is often overlooked by application developers is the deployment process. In the next chapter, we will look at a way of...
