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.

Practical Example - Building a Static Server

We have looked at Node.js and what it has to offer in the past few chapters. While we have not gone over every module or everything that Node.js has to offer, we have all the pieces to put together a static content/generator site. This means that we will set up a server to listen for requests and build pages off of that request.

To implement this server, we will need to understand how site generation works, and how we might implement this as an on-the-fly operation. On top of this, we will look at caching so that we do not have to recompile every single time a page is requested. Overall, in this chapter, we will look at and implement the following:

  • Understanding static content
  • Setting up our server
  • Adding caching and clustering
