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

Streaming is one of the pillars of writing highly performant Node.js code. It allows us to not block the main thread, while still being able to process data. The Streaming API allows us to write different types of streams for our purposes. While most of these streams will be in the form of transform streams, it is nice to see how we could implement the other three.

The final topic we will look at in the next chapter is data formats. Handling different data formats besides JSON will allow us to interface with many big data providers and be able to handle the data formats that they like to use. We will see how they utilize streaming to implement all of their format specifications.
