A comprehensive guide to reactive web development with SolidJS and TypeScript

SolidJS: The Complete Guide is the most comprehensive resource available for learning SolidJS from the ground up.

Starting with the fundamentals of Solid’s reactivity system, you’ll explore signals, effects, memos, computations, and JSX rules before diving into advanced topics like context, stores, directives, asynchronous data handling, routing, and server-side rendering. Each chapter builds on the previous one, ensuring you gain both a conceptual understanding and practical experience.

The book also covers Solid Router and SolidStart, giving you practical insights into building modern, production-ready applications. Through plenty of hands-on examples, you’ll learn routing strategies, data fetching, authentication, server functions, and full-stack development patterns—everything you need to ship real-world SolidJS apps with confidence.

By the end, you’ll be ready to build scalable, reactive, and production-grade applications with SolidJS and SolidStart.

Print length: 534 pages.

The book includes more than 250 ready-to-run examples in its companion repository.
