D3 Start to Finish shows you how to build a custom, interactive and beautiful data visualisation using the JavaScript library D3.js (versions 6 & 7). The book covers D3.js concepts such as selections, joins, requests, scale functions, events & transitions. You'll put these concepts into practice by building a custom, interactive data visualisation.

Lots of design token-related tips and tricks to learn in this book — from design tools to production, with an emphasis on the fact tools and automation are only useful if good communication is happening between designers and developers in the first place. -- @kaelig, Development acceleration at @Shopify -- Co-chair @DesignTokens

Imagine creating dynamic, interactive web applications with minimal JavaScript. That’s the revolutionary promise of htmx, a technology that redefines frontend development. This book is your gateway to mastering htmx alongside Java, Spring Boot, and Thymeleaf, transforming the way you build web interfaces.

All software design is composition: the act of breaking complex problems down into smaller problems and composing those solutions. Most developers have a limited understanding of compositional techniques. It's time for that to change.

SolidJS is one of the fastest-growing reactive UI libraries—blazing fast, predictable, and simple to use. SolidJS: The Complete Guide takes you from first steps to production-ready applications, covering everything from signals, effects, and JSX rules to routing, SSR, and SolidStart. You’ll also master Solid Router for navigation and SolidStart for building full-stack apps, with plenty of real-world examples for hands-on practice. Whether you’re a beginner in reactive programming or a React developer curious about Solid’s unique approach, this book gives you the knowledge and techniques to write cleaner, more efficient code.

The latest version of WebAssembly has arrived and it has some really cool new features. I knew that I had to completely rewrite this book to make sure it was up to date. Now, here we are. Within this book, I will take you from the very basics of memory, control flow, and the mechanics that make Wasm work, through to compiling multiple languages, building multi-threaded applications, and optimising for real-world performance.

JSON succeeded not because it was better--XML had schemas, namespaces, and 10 years of tooling, but because it understood modularity in ways XML never could. This book deconstructs how a deliberately incomplete format defeated a comprehensive standard, then shows you the production patterns (JSON Schema, JSONB, MessagePack, versioning strategies) that make JSON systems scale from prototype to billions of requests.

Learn the fundamentals of HTML, SVG, CSS and JavaScript for building data visualisations on the web. Ideal if you're wanting to learn D3.js or you use Python and/or R and wish to get started with HTML, SVG, CSS and JavaScript. Straight to the point with lots of code examples.

In this book, you'll uncover strategies that industry professionals use to build scalable, performant, and maintainable React applications, all without becoming overwhelmed by complexity.

The foundation of all programs is organization of variables/functions into nested scopes. Yet, many never contemplate how & why these decisions are made and the impacts on code maintainability. Scope & Closures examines lexical scope, builds on its principles for the power of closure, and digs into the module pattern for better program structure.

Every Node.js developer uses asynchronous code but only a few truly understand what happens behind the scenes. This book reveals the internals of the Node.js Event Loop, including microtasks, macrotasks, and concurrency under load. You'll learn to master performance, scalability, and non-blocking architecture at a level that sets professionals apart.

Cut through the noise of modern JavaScript tooling. This hands-on guide shows how Node.js, Bun, pnpm, Vite, TypeScript, Biome, Vitest and more fit together in real production workflows. Learn what each tool solves, when to use it and how to build faster, cleaner and more reliable applications in 2026.

Build real-time web apps that hold up beyond the demo. This hands-on guide takes you from WebSocket fundamentals and Socket.IO essentials to security, Redis scaling, monitoring and production deployment. Learn how the pieces work, why they matter and how to build fast, reliable systems ready for serious traffic.

A PWA is a web application that can be used on any device, under any network condition. There are certain traits that applications have, but web applications do not. Throughout the book we'll take a look at how to add app like features to web apps in order to make them work offline, perform under any network connection and become re-engeagable.
